,What structure acts as a selective barrier to control what enters and exits the nucleus?
✔✔ Nuclear envelope.
What is the primary function of microtubules in the cell?
✔✔ To provide structural support and facilitate intracellular transport.
Which organelle helps to maintain the cell’s internal environment by regulating ion
concentrations?
✔✔ Endoplasmic reticulum.
What is the role of centrioles in cell division?
✔✔ To organize microtubules and facilitate the separation of chromosomes.
What is the function of vacuoles in plant cells?
✔✔ To store nutrients, waste products, and help maintain turgor pressure.
What is the function of the nucleolus within the nucleus?
✔✔ To produce ribosomal RNA and assemble ribosomes.

, How do plant cell walls differ from animal cell membranes?
✔✔ Plant cell walls provide structural support and are rigid, whereas animal cell membranes are
flexible and lack a rigid cell wall.
What is the role of chloroplasts in plant cells?
✔✔ To carry out photosynthesis and convert light energy into chemical energy.
Which cell organelle is involved in the detoxification of harmful substances?
✔✔ Smooth endoplasmic reticulum.
What is the primary function of microtubules in the cytoskeleton?
✔✔ To provide structural support and assist in cell division.
How does the structure of the cell membrane contribute to its function?
✔✔ The cell membrane’s phospholipid bilayer allows selective permeability, regulating the
entry and exit of substances.
