Why do we eat roots of some plants?
Because.. ~ in some plants root get modify to do special function other than conduction of water and mineral. ~ For example Carrot potato and Beetroot in which root get modify for the storage of nutrients.
What happens to the food prepared by a leaf?

How do green leaves make food?
Green plants have the ability to make their own food. They do this through a process called photosynthesis which uses a green pigment called chlorophyll. … Through photosynthesis the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose a type of sugar.
When plants make their own food?
Plants make their own food by a process called Photosynthesis. Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy and stored in the form of starch which can be used later. Photosynthesis is a key process in the growth of plants.
How Excess food is stored?
Excess glucose is made into glycogen which is stored in the liver and muscles. Aerobic conditioning can increase muscle storage levels five-fold. Dietary carbohydrates eaten in excess are converted into fatty acids and stored in adipose tissue.

When plants make their food excess is stored as?
StarchStarch. When a plant produces glucose in excess it can be converted into starch and stored usually in the roots and seeds of the plant where it is kept as a long-term energy reserve for the plant.
What do plants do with the food they produce?
Plants use the energy stored in the sugar created in photosynthesis and the carbon hydrogen and oxygen that make up sugar along with other elements they absorb from the soil to build the tissue of their bodies and make everything they need to run their metabolisms.
How Do Plants Eat? What is Photosynthesis?
Where is the excess food made by plants stored?
The food synthesized by the plant is stored as starch.
Why do plants store food?
Plants Store their extra food in fruits stems roots and leaves. Storing the food helps them to use it in winter and survive because there is very little sunlight available and so they photosynthesize less.
How do plants store their extra food?
Plants store their food in the form of starch in various parts of them. Starch is a polysaccharide of glucose monomers. Glucose residues are linked by glycosidic bonds. This starch can be stored in the leaves stems roots flowers fruits and seeds of a plant.
How do plants make food without leaves?
Plants like cacti don’t have leaves in the traditional sense. (Their spines are actually modified leaves.) But the cells in the body or “stem” of the cactus plant still contain chlorophyll. Thus plants like cacti can absorb and convert energy from the sun through the process of photosynthesis.
What part of plant is used for food?
Leaves: The flat green bladelike part of a plant. Stems: The main stalk of the plant. Fruit: The sweet and fleshy product of a tree or other plant that contains seed and can be eaten as food. Seeds: The small capsules within the fruit or grain of a plant that are capable of developing into another plant.

Do we eat the roots of plants?
We eat the root of some plants the leaves of other plants and we eat the fruit. It is seldom that we eat the entire mature plant. Usually when we eat plants we call them either fruits or vegetables. Since most plant foods are grouped into the two groups many of the foods we eat as vegetables are actually fruits.

What will happen to the excess food produced during photosynthesis?
The excess is released from the leaves making it available for respiration to animals and many microorganisms.
How plants make food by photosynthesis?
Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis which means ‘making out of light’. The foods are called glucose and starch.
Which part of the plant are eaten as food?
Plants have leaves roots stem flowers as their parts. We consume almost every part of the plant (root stem leaves flowers fruits etc) as food. Fruits vegetables grains seeds herbs are the foods we eat that are obtained from plant sources.
