Cell Biology Quiz
Transportation Mechanisms
- Active Transport: The movement of molecules from an area of low concentration to an area of high concentration, requiring energy from the cell.
- Passive Transport: The movement of molecules from an area of high concentration to an area of low concentration, without using energy from the cell.
Cell Organelles in Plants and Animals
-
Plant Cell Organelles:
- Chloroplasts: Responsible for photosynthesis, present in plant cells.
- Vacuoles: Store water, nutrients, and waste products, larger in plant cells.
-
Animal Cell Organelles:
- Lysosomes: Contain digestive enzymes, responsible for breaking down waste and foreign substances.
- Centrioles: Involved in the formation of cilia, flagella, and spindle fibers.
Cell Division
Meiosis
- Purpose: Produces gametes (sperm and egg cells) with a unique combination of chromosomes.
- Process: Involves two successive cell divisions, resulting in four non-identical daughter cells.
Mitosis
- Purpose: Produces two identical daughter cells with the same number of chromosomes as the parent cell.
- Process: Involves one cell division, resulting in two identical daughter cells.
