What are two major differences between spermatogenesis and oogenesis?
Complete answer:
Spermatogenesis | Oogenesis |
---|---|
Produces motile gametes | Produces non-motile gametes |
Four sperms are formed by the equal cytokinesis that occurs during spermatogenesis. | One ovum and four polar bodies are produced by unequal cytokinesis occurring during oogenesis. |
What is Gametogenesis write the difference between spermatogenesis and oogenesis?
Spermatogenesis leads to the formation of sperms, whereas oogenesis helps in the formation of ova. The fertilization of sperm and ova leads to the formation of a zygote which further develops into an embryo….Spermatogenesis vs Oogenesis.
Spermatogenesis | Oogenesis |
---|---|
Produces motile gametes | Produces non-motile gametes |
What is similar between spermatogenesis and oogenesis?
Spermatogenesis and Oogenesis have following similarities: 1)Both process occurs inside the gonads (testes and ovaries). 2)Both are completed in three phase ; multiplicative, growth and maturation phase.
What is the difference between spermatogenesis and Spermiogenesis?
Sperms are the male gametes produced in the seminiferous tubules of the testes. The main difference between spermatogenesis and spermiogenesis is that spermatogenesis is the formation of sperm cells whereas spermiogenesis is the maturation of the spermatids into sperm cells.
What hormone stimulates a primordial follicle to develop into a primary follicle?
follicle stimulating hormone (FSH)
At sexual maturity, two hormones, produced by the pituitary gland: follicle stimulating hormone (FSH) and lutenising hormone (LH) cause these primordial follicles to develop. In each ovarian cycle, about 20 primordial follicles are activated to begin maturation.
Why does the female body produce one egg cell and three polar bodies?
The one egg cell that results from meiosis contains most of the cytoplasm, nutrients, and organelles. This unequal distribution of materials produces one large cell, and one cell with little more than DNA. This other cell, known as a polar body, eventually breaks down.
What are the stages of spermatogenesis?
Spermatogenesis can be divided into three phases: (1) proliferation and differentiation of spermatogonia, (2) meiosis, and (3) spermiogenesis, a complex process that transforms round spermatids after meiosis into a complex structure called the spermatozoon.
What is the difference between spermatogenesis and oogenesis?
The process of spermatogenesis is the basis for sexual reproduction which permits genetic recombination, resulting in genetic variation among the species. Oogenesis is the process of formation of female gamete or ovum through a series of mitotic and meiotic divisions occurring in the female reproductive system.
Where does oogenesis take place in the ovary?
Oogenesis is the process of the formation of mature female gametes from oogonia in the ovary. The process normally takes place in three phases such as multiplication, growth, and maturation. The process results in the formation of a diploid cell that undergoes meiosis to result in a single ovum.
When does spermatogenesis begin and when does it end?
Spermatogenesis is a continuous process that begins with puberty and continuous until death. The early stages of oogenesis begin in the fetal stage while the rest continue after puberty till menopause.
How is spermatogenesis regulated in the male reproductive system?
The head consists of acrosomes that secrete enzymes and helps in the entry of sperm inside an ovum. The overall process of spermatogenesis is regulated by various glands and their products. The luteinizing hormone by the pituitary gland regulates the formation of sperm and the production of testosterone in the male reproductive system.
