Question

multiple select question
select all that apply
select all of the following that are the main parts of most cells.

plasma membrane
tissue fluid
extracellular fluid
cytoplasm
nucleus

Explanation:

To determine the main parts of most cells, we analyze each option:

• Plasma membrane: It encloses the cell, controlling substance entry/exit, and is a main cell part.
• Tissue fluid: It's the fluid surrounding cells in tissues, not a part of the cell itself.
• Extracellular fluid: This is the fluid outside cells (including tissue fluid), so it's not a cell part.
• Cytoplasm: It's the region between the plasma membrane and nucleus (in eukaryotes), containing organelles and cytosol, and is a main cell part.
• Nucleus: In eukaryotic cells, it contains genetic material and is a key cell part (prokaryotes lack a nucleus but most cells here likely refer to eukaryotic or the general cell structure including those with nuclei).

Answer:

• Plasma membrane
• Cytoplasm
• Nucleus
