Sertoli cell (nurse cells), nourish and protect developing spermatozoa.
A developing sperm cell begins to grow a tail during the spermatid stage of spermatogenesis. This process occurs as part of sperm cell maturation, where spermatids undergo elongation and develop their characteristic tail to enable them to swim and fertilize an egg.
Developing sperm are known as spermatocytes which develop into spermatids. Mature sperm are known as spermatazoa.
Mitochondria are located in the tail of the sperm. They provide the sperm with that whip like energy to move. They can give the energy to the sperm because mitochondria are the "powerhouse" of the cell.
A single pollen grain has 2 sperm. Double fertilization occurs when 1 of these sperm combines with the egg, and the other sperm combines with a cell (this is called endosperm) That is in order for the seed to keep being produced.Seed has to be germinated, and without the extra sperm (double fertilization) the plant couldn't germinate and would go extinct.
No, the egg does not destroy the sperm's mitochondria. During fertilization, the sperm cell's mitochondria are typically destroyed, as the egg provides the necessary energy-producing organelles for the developing embryo.
The cytoplasm in the egg cell contains stored food reserves to provide nutrients and energy for the developing embryo once fertilization occurs. This is because the egg cell needs enough resources to support the early stages of embryonic development until it is able to obtain nutrients from its environment.

Question:At the beginning of prophase I there are ________ molecules of DNA in a developing human sperm cell.Your Answer:2392CORRECT ANSWER46INCORRECThalf as many (as compared to somatic cell)twice as many (as compared to mature sperm)
The mitochondria provide energy to the sperm's 'tail' (flagellum) so that it can move, and propel the sperm cell forward.
provide DNA to an egg to form an offspring

The combining of an egg and sperm to create 1 single cell is "conception."
Humans start out as the fusion of a sperm cell from the father and an egg cell from the mother, resulting in a fertilized egg called a zygote. This zygote then begins to divide and grow, eventually developing into a mature human being.
