1.True or false? Gametogenesis is the same as meiosis?

2. Name two types of gametogenesis and how they are different from each other.

3 Why is it important that only one viable egg cell is produced during meiosis in females?

Respuesta :

1. False. They are similar, though.

meiosis- A kind of cell division involving having the chromosome number. It is responsible for genetic recombination.

Gametogenesis- It's the process when gametes or germ cells are produced in an organism. They undergo meiosis to form gametes.

2. Spermatogenesis- happens in the testes of males. 4 gametes are produced. Spermatogenesis involves a metamorphosis stage called spermiogenesis. Spermatogenesis produces small, motile spermatozoa

Oogenesis- takes place in the ovary in a female. 1 gamete produced. in oogenesis there is no metamorphosis stage. In oogenesis the ovum is spherical, and isn't motile and is bigger with more food reserves and cytoplasm.

3. Because The one egg cell that results from meiosis contains most of the cytoplasm, nutrients, and organelles.

1. No, Gametogenesis is not same as meiosis.

What is gametogenesis?

The creation of gametes from haploid progenitor cells is known as gametogenesis.

What is meiosis?

Meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm).

2. Gametogenesis are classified into two types. They are

  • Spermatogenesis
  • oogenesis.

What is Spermatogenesis?

Spermatogenesis is the scientific name for the production of sperm cells.

To create spermatozoa, rounded immature sperm cells go through many mitotic and meiotic divisions (spermatocytogenesis), a metamorphic change (spermiogenesis), and a metastatic transformation.

What is oogenesis?

The process of developing mature female gametes from primordial germ cells is known as oogenesis.

3. Meiosis produces one egg, which has the greatest nutrition, cytoplasm, and organelles. One huge cell and one cell with more DNA result from the uneven distribution of chemicals (polar body which gradually degenerates).

What is cytoplasm?

The gelatinous liquid that makes up a cell's interior is called cytoplasm.

What is organelles?

Inside cells, organelles are specialized structures that carry out a variety of tasks.
