Question

select all the true statements.
in plant cells, mitochondria store sugar, and vacuoles break down the sugar to release energy.
the cell membrane and cell wall separate a plant cell from its surroundings.
plant cells do not have mitochondria, but animal cells can have them.
an animal cell has a cell membrane, but a plant cell does not.

Explanation:

• Cell Membrane: Both plant and animal cells have a cell membrane. So, "An animal cell has a cell membrane, but a plant cell does not" is false.
• Mitochondria: Both plant and animal cells have mitochondria. So, "Plant cells do not have mitochondria, but animal cells can have them" is false.
• Cell Membrane and Cell Wall Function: The cell membrane and cell wall (in plant cells) do separate the cell from its surroundings. So, "The cell membrane and cell wall separate a plant cell from its surroundings" is true.
• Mitochondria and Vacuoles Function: Mitochondria break down sugar to release energy, and vacuoles can store substances (but not sugar in the way described here. However, focusing on the core function of mitochondria - energy release from sugar breakdown (cellular respiration) - this statement has an element of truth. The more accurate part is that mitochondria are involved in energy release from organic compounds like sugar through cellular respiration).

Answer:

The cell membrane and cell wall separate a plant cell from its surroundings.
