A polar body is a ?primordial follicle a tiny cell consisting of a nucleus and a small amount of cytoplam that is devoid of organelles the first stage of mitosis after fertilization occurs . a teriary follicle the area of the cell where mitotic spindles form during metaphase
A polar body is a tiny cell that forms during oogenesis (egg development) in females. It is produced during the first stage of meiosis (not mitosis) after fertilization occurs. A polar body contains a nucleus and a small amount of cytoplasm but is devoid of organelles. It is eventually discarded and does not contribute to the development of the embryo.
A primordial follicle refers to a stage of ovarian follicle development where a single oocyte (immature egg) is surrounded by a layer of supporting cells.
A tertiary follicle is also known as a mature or Graafian follicle. It is the final stage of follicle development before ovulation, characterized by a fluid-filled cavity called the antrum and a fully developed oocyte.
The area of the cell where mitotic spindles form during metaphase is called the spindle apparatus. It is responsible for separating chromosomes during cell division. However, it is not directly related to polar bodies or follicle development.
A polar body is a small, non-functional cell that is formed during the process of oogenesis, which is the development of eggs in females. It is not directly associated with any specific stages of mitosis after fertilization.
To provide some additional context, let's break down the information you mentioned:
1. Primordial follicle: A primordial follicle is an early stage of follicle development in the ovaries. It consists of a single primary oocyte surrounded by a layer of flattened cells.
2. Tiny cell with a nucleus and cytoplasm devoid of organelles: This description matches the general characteristics of a polar body. A polar body is a byproduct of oocyte maturation and is responsible for discarding excess genetic material during the process.
3. First stage of mitosis after fertilization occurs: After fertilization, the zygote is formed, and it undergoes a series of cell divisions through mitosis to develop into an embryo. It does not specifically refer to polar bodies, as they are not involved in this process directly.
4. Tertiary follicle: A tertiary follicle, also known as a mature or Graafian follicle, is a fully developed ovarian follicle that is ready to release the egg during ovulation.
5. Area of the cell where mitotic spindles form during metaphase: The area where mitotic spindles form during metaphase is called the spindle apparatus. It is responsible for aligning and separating chromosomes during mitosis.
In summary, while the information you provided contains accurate descriptions of various terms related to reproduction and cellular processes, they are not directly connected in the way described.
