1. Name the stage of cell division in which paired homologous chromosomes get shortened and thickened?

The stage of cell division in which paired homologous chromosomes get shortened and thickened is prophase I of meiosis. During this stage, the chromosomes condense and become visible as distinct structures, allowing for the homologous chromosomes to pair up and exchange genetic material through a process called crossing over. The shortening and thickening of the chromosomes during prophase I is important for proper alignment and separation of the homologous chromosomes during subsequent...

Describe mitosis with labeled diagram.

Mitosis is a complex process of cell division that allows a single cell to produce two identical daughter cells. It consists of several distinct stages, each with specific events and changes occurring within the cell. Here is a simplified description of the process of mitosis:

1. Interphase: This is the phase before mitosis actually begins. The cell undergoes growth and replicates its DNA to ensure each daughter cell receives a complete set of genetic information. Interphase is divided into...

Can sexual reproduction occur without meiosis cell division? Why not?

Sexual reproduction is not possible without meiosis cell division because meiosis cell division male and female gamete cannot be formed and sexual reproduction is impossible. So, meiosis cell division is essential in sexual reproduction.

7. explain cell plate cytokinesis 

Cell plate cytokinesis is a type of cell division that occurs in plant cells, where a new cell wall is formed to separate two daughter cells. This process occurs during the later stages of cell division, specifically during telophase and cytokinesis.

During the process of cell division in plant cells, the spindle fibers pull the chromosomes towards opposite poles of the cell, and a new cell wall needs to be formed to separate the two daughter cells. However, since plant cells have a cell wall...

6. differentiate between animal cytokinesis and plant cytokinesis?

In plant cytokinesis, cells are divided by the formation of a cell plate in the middle of the mother cell whereas, in animal cytokinesis,cells are divided by the formation of a cleavage furrow on both sides of the mother cell. similarly,cell wall formation does not occur during animal cytokinesis while cell walls form during plant cytokinesis.

4. What are homologous chromosomes? What happens to homologous chromosomes during meiosis?

Homologous chromosomes are a set of one maternal and one paternal chromosome.In meiosis homologous chromosomes pair and allows the crossing over of genetic material. This process is known as recombination.
