Classify each cell as haploid or diploid. 1. microspore:
Alex17521 [72]

Answer:

microspore: haploid

2. first polar body: haploid

3. spermatid: haploid

4. ovum: haploid

5. secondary oocyte: haploid

6. primary spermatocyte: diploid

7. microsporocyte: diploid

8. oogonium: diploid

9. megaspore: haploid

10. spermatogonium: diploid

Your answer

Explanation:

1. Microspore is a haploid spore produced by mostly ferns. They give rise to male gametophytes, which in turn produces sperm cell.

2. Polar body is one of the haploid cells that forms during the process of oogenesis (gametogenesis), specifically when the primary oocyte undergoes an unequal division.

3. A spermatid is an haploid cell that arises from the second meiotic division of the spermatogonia.

4. The ovum is the female gamete of most sexual reproducing organisms. It is also called the EGG CELL. It is haploid.

5. Secondary oocyte are haploid cells that results from the meiotic division of the primary oocyte.

6. Primary oocyte is the diploid cell that starts the meiotic division during oogenesis. It arises from the mitotic division of the oogonium.

7. The microsporocyte is the diploid cell that undergoes meiotic division to produce microspores in ferns and other land plants.

8. Oogonium are the diploid stem cells that initially starts the oogenesis process. It undergoes mitosis to form the primary oocyte, which divides meiotically till the ovum is formed.

9. Megaspore is a haploid spore that gives rise/germinates to the female gametophyte in ferns. The female gametophyte produces the haploid eggs.

10. Spermatogonium are undifferentiated stem cells that produces the sperm cells in males via the process of spermatogenesis. The spermatogonia is diploid in nature

8. Which of the following statements is true about meiosis?
Mariulka [41]

Answer:

B

Explanation:

Meiosis produces gametes that contain one complete haploid set of chromosomes

Meiosis is a reduction division, where the number of chromosomes in the daughter cells is reduced to half as compared to the parent cell. This set of chromosomes is called a haploid set or genome. The reduction from diploid to haploid occurs during Anaphase I of meiosis I, where homologous chromosomes separate and enter into two different cells. Meiosis takes place only in reproductive cells that divide to form gametes

So, the correct answer is 'Meiosis produces gametes that contain one complete haploid set of chromosomes'

hope that helps

According to cell theory,
Nataliya [291]

The right answer is D.

The cell is a biological unit (living) structural, functional and fundamental living beings, of variable size (between 10 to 100 microns).

Physically, a cell is a compartmentalized compartment by a membrane in which all the molecules are grouped together. A cell is able to fulfill different functions of the body, such as reproduction and growth (multiplication of cells), or even metabolism (sum of catabolism (degradation activity) and anabolism (synthesis activity)) .

The cells are autonomous but remain coordinated with each other to complete tasks together (such as, for example, the coordination of dendritic cells to eliminate a pathogen during an immune reaction).

There are two main types of cell organisms: Eukaryotic cells have a nucleus containing the genetic material. Prokaryotic cells lack nuclei, so their genetic material is free in the cell (eg bacteria).
