What is meant by somatic cell?
A somatic cell is any cell of the body except sperm and egg cells. Somatic cells are diploid meaning that they contain two sets of chromosomes one inherited from each parent. Mutations in somatic cells can affect the individual but they are not passed on to offspring.
What is a chromosome apex?
A chromosome is made of a single long DNA double helix wrapped around proteins called histones. The DNA and histones together form a nucleosome. The nucleosomes pack together to form a chromosome.
Are neurons somatic cells?
Let’s take a look at a specialized group of somatic cells called neurons. Neurons are nerve cells and their function is to transmit signals from the body to the brain. The physical characteristics of neurons are unique. They have a large central area called the cell body.

What are specialized reproductive cells called?
gameteA gamete is a specialized reproductive cell . The cells usually have one half as many chromosomes in their nuclei as the majority of body cells which are known as somatic cells. All sexually-reproducing plants animals and microbes produce gametes sometime during their life span. See also who was hesiod
What are reproductive cells that unite to form a new cell called zygote?
Gametes are reproductive cells that unite during sexual reproduction to form a new cell called a zygote. This condition is called ‘anisogamy’ or ‘heterogamy’ wherein the female and male gametes are of different sizes (in the case of humans the ovum is ~20 times larger than the sperm cell).
What do reproductive cells contain?
Reproductive cells: The eggs and sperm are the reproductive cells. Each mature reproductive cell is haploid in that it has a single set of 23 chromosomes containing half the usual DNA amount.
What is a fertilized egg called?
When sperm fertilizes (meets) an egg this fertilized egg is called a zygote (ZYE-goat). The zygote goes through a process of becoming an embryo and developing into a fetus. The male reproductive system and the female reproductive system both are needed for reproduction.

What is in the sperm cell?
A Sperm Cell or Spermatozoa. The mature sperm cell (spermatozoa) is 0.05 milliliters long. It consists of a head body and tail. The head is covered by the ac cap and contains a nucleus of dense genetic material from the 23 chromosomes. See also how many miles is 800m
What does haploid cell mean?
Haploid describes a cell that contains a single set of chromosomes. The term haploid can also refer to the number of chromosomes in egg or sperm cells which are also called gametes. … The number of chromosomes in a single set is represented as n which is also called the haploid number. In humans n = 23.
Do males and females have a cervix?
Men do not biologically have a cervix because it is part of the female reproductive system. Meanwhile some women need to have them removed or in very rare cases are not born with a cervix.

How do diploid cells reproduce?
Diploid cells have two sets of chromosomes. … A diploid cell replicates or reproduces through mitosis. It preserves its diploid chromosome number by making an identical copy of its chromosomes and distributing its DNA equally between two daughter cells.
What are daughter cells called in meiosis?
haploidThe process results in four daughter cells that are haploid which means they contain half the number of chromosomes of the diploid parent cell. Meiosis has both similarities to and differences from mitosis which is a cell division process in which a parent cell produces two identical daughter cells.
What is the name of a reproductive cell?
In the human reproductive process two kinds of sex cells or gametes (GAH-meetz) are involved. The male gamete or sperm and the female gamete the egg or ovum meet in the female’s reproductive system.
How do sperm get to the egg?
Fertilization: after sperm arrive the magic happensSee also How Long Do Wolf Pups Stay With Their Mother? The magic happens in the fallopian tubes. As the fallopian tube pushes the egg towards the uterus cilia push the sperm towards the egg.
What is the function of reproductive cell?
To produce egg and sperm cells. To transport and sustain these cells. To nurture the developing offspring. To produce hormones.
What is the somatic reproduction?
the process by which a living entity or organism produces a new individual of the same kind. The sex glands or gonads (the ovaries in the female and the testes in the male) produce the germ cells (ova and sperm) that unite and grow into a new individual.
What is the term for a male reproductive cell apex?
The term for a male reproductive cell is called a sperm cell.
What is meant by diploid cells?
Diploid describes a cell that contain two copies of each chromosome. Nearly all the cells in the human body carry two homologous or similar copies of each chromosome. … Germ line cells are haploid which means they contain a single set of chromosomes.
What is the difference between vegetative cell and generative cell?
Generative cell divides and forms sperm cells that are male gametes of the flowering plants. The key difference between vegetative and generative cell is that vegetative cell is non-reproductive while the generative cell is reproductive.

What are human reproductive cells?
The formation of sex cells is a central part of human reproduction: In fertilization an egg cell and a sperm cell combine. These sex cells are also called reproductive cells or gametes. Sperm cells are produced in men’s testicles and egg cells are produced in women’s ovaries.
What are vegetative cells called?
