Question

which of the following is a primary function of the nucleus in both plant and animal cells?
options: producing energy for the cell, storing the cell’s genetic material, regulating the movement of substances into and out of the cell, synthesizing proteins

what is the main role of the cytoplasm in a cell?
options: to provide a site for most cellular activities and contain organelles, to control cell division, to produce lipids and carbohydrates, to protect the cell from its external environment

the outer boundary of an animal cell is the ______, which controls what enters and exits the cell.
your answer:

which of the following describes the primary function of mitochondria in both plant and animal cells?
options: carrying out photosynthesis, generating atp (energy) through cellular respiration, storing water and nutrients, synthesizing proteins

what is the main function of the cell wall in a plant cell?
options: to provide structural support and protection to the cell, to store genetic information, to regulate the passage of molecules into and out of the cell, to synthesize proteins for the cell

Explanation:

First Question (Nucleus function)

• "Producing energy for the cell" is done by mitochondria, not the nucleus.
• The nucleus contains DNA, which is the cell’s genetic material, so "Storing the cell’s genetic material" is correct.
• "Regulating the movement of substances into and out of the cell" is the cell membrane’s function.
• "Synthesizing proteins" is done by ribosomes (with mRNA from the nucleus, but synthesis itself is ribosomes’ job).

• The cytoplasm is the gel - like substance where most cellular activities occur and it contains organelles.
• "To control cell division" is the nucleus’ role.
• "To produce lipids and carbohydrates" is more related to the endoplasmic reticulum.
• "To protect the cell from its external environment" is the cell membrane (and cell wall in plants)’s function.

The cell membrane (plasma membrane) is the outer boundary of an animal cell. It is a selectively permeable membrane that controls what enters and exits the cell.

Answer:

B. Storing the cell’s genetic material (assuming the options are labeled A - D as per typical multiple - choice, with the second option being this one)

Second Question (Cytoplasm role)
