Question

CELLULAR REPRODUCTION (Chapter 9) 1. Distinguish between: a. parent cell and daughter cells b. stem cells and differentiated cells c. sexual and asexual reproduction d. prokaryotic (binary) fission and eukaryotic mitotic cell division

Answer 1

1. How can we understand the difference between parent cell and daughter cell.

Explaination:---

In cell division, a parent cell is the cell that divides to give rise to two daughter cells.

In mitosis, the two daughter cells contain the same genetic content as the parent cell.

In meiosis, the daughter cells have different genetic content and half the number of chromosomes of the parent cell.

2. Stem cell:-- A stem cell is a cell with the unique ability to develop into specialised cell types in the body. In the future they may be used to replace cells and tissues that have been damaged or lost due to disease. But

Differntiated cell:-- Cellular differentiation is the process where a cell changes from one cell type to another. Usually, the cell changes to a more specialized type. eg. some cells change into neurons, RBC, etc.

3. *Asexual reproduction means reproducing without the interaction of two sexes or genders, whereas

*sexual reproduction involves the fusion of two special cells called gametes, one from a male source and one from a female source.

4. Key point is that Binary fission is different from mitosis because prokaryotic cells do not have a true nucleus like eukaryotes.
