Why is photosynthesis important?
Photosynthesis can be considered the fundamental life process for nearly all plants and animals. It provides the source of energy that drives all their metabolic functions and the oxygen required for respiration.
What is a chloroplast and its function?
A chloroplast is an organelle within the cells of plants and certain algae that is the site of photosynthesis which is the process by which energy from the Sun is converted into chemical energy for growth.
Why Do Plants Need Chloroplasts And Mitochondria?
Plant cells need both chloroplasts and mitochondria because they perform both photosynthesis and cell respiration. Chloroplast converts light (solar) energy into chemical energy during photosynthesis while mitochondria the powerhouse of the cell produces ATP- the energy currency of the cell during respiration.Plant cells need both chloroplasts and mitochondria because they perform both photosynthesis and

Why is it important that plant and animal cells both have mitochondria?
It is important to note that plants need both chloroplasts and mitochondria because without one organelle say the mitochondria the entire cell would be unable to carry out its life activities. … Thus both organelles are equally important for normal cellular function.
Why do plants need a mitochondria?
Explanation: Plant cells require mitochondria to produce energy for the cell usually through photosynthesis during the day. When the sun sets and the energy from sunlight is lost the plant continues on through the night producing energy through cellular respiration.
What is the function of chloroplast and mitochondria?
Mitochondria are the “powerhouses” of the cell breaking down fuel molecules and capturing energy in cellular respiration. Chloroplasts are found in plants and algae. They’re responsible for capturing light energy to make sugars in photosynthesis. See also what is plottage in real estate
Why is the mitochondria the most important organelle?
As the power plants in virtually every human cell (as well as animal plant and fungi cells) mitochondria play an essential role in creating energy to drive cellular function and basically all of our biological processes.
Why can a cell survive without mitochondria?
Without mitochondria (singular mitochondrion) higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen) a process much less efficient than aerobic respiration.
Role of Chloroplast and Mitochondria
What are the roles of chloroplast and chlorophyll in photosynthesis?
What are the roles of chloroplasts and chlorophyll in photosynthesis? Chloroplasts contain a light absorbing molecule called chlorophyll and this is the place in plants where photosynthesis takes place.
How do mitochondria and chloroplast work together in plants to sustain life which organelle would a plant have more of why?
How do the chloroplast and mitochondria work together to keep plant cells alive? Chloroplasts convert sunlight into food during photosynthesis then mitochondria makes energy out of the food in the form of ATP.
What would happen if there was no chloroplast in a plant cell?
Without chloroplasts plants would not be able to get their energy from the sun and would cease to survive leaving us without food. On the other hand without mitochondria animals would be lacking in cellular energy and would also fail to survive.
What is an important function of mitochondria?
Mitochondria. Mitochondria are membrane-bound cell organelles (mitochondrion singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
Why do plant cells need chloroplasts and animal cells don t?
Plant cells have chloroplasts while mitochondria are found only in animal cells. Because plants cannot obtain sugar from food they must rely on sunshine to do it. The chloroplast is where this process (photosynthesis) occurs. A plant requires sunlight carbon dioxide (CO2) and water to perform photosynthesis.
What is the relationship between a chloroplast and a mitochondria Why does a mitochondria need chloroplasts and vice versa?
Chloroplasts and mitochondria do not knowingly work together. However the glucose and oxygen produced by photosynthesis in the chloroplasts are required by the mitochondria in order to carry out aerobic cellular respiration.
How do chloroplasts and mitochondria work together?
-Chloroplasts convert the sunlight (absorbed by the chlorophyll) into food and then mitochondria make/produce energy out of the food in the form of ATP.
What would happen if the chloroplast was removed from a cell?
Chloroplasts are the organelles which gives color to the plant and helps the leaves to capture the sunlight to perform the process of photosynthesis. Therefore if chloroplasts are taken out of the leaves then the plant will not be able to do its photosynthesis. As a result the plant will die.
Why chloroplast is absent in animal cell?
Green plants are autotrophs which make their food themselves need chloroplast. In animal cell it is absent because animal are heterotrophs i.e they are depend on other organisms for food and they can not make their food themselves. So thy does not need chloroplast.
Can a plant cell survive without mitochondria?
No plants cannot live without mitochondria. Mitochondria is a vital cell organelle for the survival of all living cells. In plants this cell organelle plays an important role in capturing energy in cellular respiration.
How does chloroplast help in photosynthesis?
Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis.
Why do plant cells have both chloroplasts and mitochondria and animal cells have only mitochondria?
Plant cells need both chloroplasts and mitochondria because they perform both photosynthesis and cell respiration. Chloroplast converts light (solar) energy into chemical energy during photosynthesis while mitochondria the powerhouse of the cell produces ATP- the energy currency of the cell during respiration.
Why do plants need chloroplasts?
Chloroplasts play an important part in the process of photosynthesis in some organisms. The chloroplast absorbs the energy in sunlight and uses it to produce sugars. Chloroplasts play an important part in the process of photosynthesis in some organisms.
The similar DNA structure in mitochondria and chloroplasts is explained by the theory of endosymbiosis which was originally proposed by Lynn Margulis in her 1970 work “The Origin of Eukaryotic Cells.” According to Margulis’s theory the eukaryotic cell came from the joining of symbiotic prokaryotes.
What role do chloroplasts play in the plant cell?
Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process.
Do plant cells have DNA?
Like all living organisms plants use deoxyribonucleic acid (DNA) as their genetic material. The DNA in plant cells is found in the nucleus the mitochondria and the chloroplasts. … DNA is a coded set of instructions for making RNA.
Why do plants need both chloroplasts and mitochondria quizlet?
Cells need both chloroplasts and mitochondria to undergo both photosynthesis AND cell respiration. After photosynthesis which chloroplasts are needed for which yields oxygen and glucose plants need to break down the glucose and they use cell respiration to do this which happens in the mitochondria.
What do mitochondria do in a plant cell?
Known as the “powerhouses of the cell ” mitochondria produce the energy necessary for the cell’s survival and functioning. Through a series of chemical reactions mitochondria break down glucose into an energy molecule known as adenosine triphosphate (ATP) which is used to fuel various other cellular processes.
What would happen if there was no mitochondria in a plant cell?
Mitochondria are known as power house of the cell. These organells contain many oxidative enzymes which oxidise the food and convert them into energy of the cell in the form if A.T.P. In the absence of mitochondria in the cell oxidation of food and release of energy does not takes place. Hence cell may die.
Do plant cells have both chloroplasts and mitochondria?
Both plant and animal cells are eukaryotic so they contain membrane-bound organelles like the nucleus and mitochondria. … Plants and animals are very different on the outside as well as on the cellular level. Both animal and plant cells have. mitochondria but only plant cells have chloroplasts.
Why is an organelle important?
Organelles are important because they help compartmentalize the cell for different functions. Different types of jobs can be specialized and regulated as they are combined to different parts of the cell.

How are the cell wall and chloroplasts important to plants?
Cell wall provide plant cells rigidity and structural support and cell to cell interaction. … Chloroplasts aid in carrying out the process of photosynthesis to produce food for the plants.
What are the two main function of chloroplast?
The main role of chloroplasts is to conduct photosynthesis. They also carry out functions like fatty acid and amino acid synthesis.
What makes plants green?
Chlorophyll is located in a plant’s chloroplasts which are tiny structures in a plant’s cells. … Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant so it appears green. See also consider what happens when you jump in the air
What is the role of mitochondria in photosynthesis?
Explanation: Photosynthesis is food production using the energy from sunlight. Chloroplasts are the organelles where photosynthesis occurs. Mitochondria are the organelles that convert the energy in food into ATP to be used as chemical energy by the cell.
Why is chloroplast better than mitochondria?
Mitochondria and chloroplast are organelles found in a plant cell.
