Explanation:

• For question 22: The cell theory states that all living organisms are made of cells and cells are the basic unit of life, which gives a foundational understanding.
• For question 23: Improper chromosome distribution during embryo mitosis can lead to developmental issues.
• For question 24: The cell - membrane's main role in an animal cell is to act as a semi - permeable barrier for regulating substances entering and leaving the cell.

Answer:

1. a. It provides a foundational understanding that all living organisms are made of cells, and cells are the basic unit of life.
2. b. Developmental abnormalities or birth defects
3. c. Acting as a semi - permeable barrier to control what enters and exits the cell.
