Question

question 2
the function of the nuclear membrane (envelope) is to:
a control the passage of materials between the nucleus and cytoplasm
b form mitochondria
c direct the activities of the cell
d transfer energy

Explanation:

The nuclear membrane (envelope) is a double - membrane structure. It has nuclear pores. These pores are responsible for regulating what goes in and out of the nucleus, thus controlling the passage of materials between the nucleus (where genetic material is stored) and the cytoplasm (the fluid part of the cell outside the nucleus).

• Option B: Mitochondria have their own structure and are not formed by the nuclear membrane.
• Option C: The nucleus (containing DNA) directs the activities of the cell, not the nuclear membrane.
• Option D: Organelles like mitochondria (for cellular respiration) and chloroplasts (in plants for photosynthesis) are involved in energy transfer, not the nuclear membrane.

Answer:

A. control the passage of materials between the nucleus and cytoplasm
