How many chromosomes does a sperm cell have at prophase I?
Sperm are all 1N (half the complement of chromosomes of the original male). Prophase 1 in meiosis the cell is 4N Prophase 2 in meiosis the cells are 2N Final division creates 1N cells.

What is the correct order for the sequence of meiosis?
Interphase Prophase 1 Metaphase 1 Anaphase 1 Telophase 1 Cytokinesis 1 Prophase 2 Metaphase 2 Anaphase 2 Telophase 2 Cytokinesis 2
Strictly speaking mitosis and meiosis are divisions of the?
Mitosis is division of a cell. Consists of the stages Prophase, Metaphase, Anaphase, and Telaphase. Mitosis is part of the cell cycle. Meiosis is the division of a sex cell. Such as sperm or egg. Meiosis is unique because it goes through the stages twice. Prophase I, Prophase II, Metaphase I, and Metaphase II, etc.
How many DNA molecules are present in a sperm cell?

What are an organism's reprodutive cells such as the sperm or egg called?
this is called prophase
Why are two sperm never identical?
No two sperm cells are identical because of the process of crossing over that occurs in prophase I of meiosis.

What is a sperm cell called during meiosis?
Developing sperm are known as spermatocytes which develop into spermatids. Mature sperm are known as spermatazoa.

Which cell provide nourishment to developing sperm?
Sertoli cell (nurse cells), nourish and protect developing spermatozoa.
What happens when a egg and sperm unite?
The sperm unites with the Ovum in the womb, to form a zygote, which is the beginning of the Embryo.
What is bunny sperm made out of?
Bunny sperm is made out of the same things human sperm is made out of. Various protein molecules, as well as sperm (the little swimmers) and other liquids and fluids from the body.
