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 endoplasmic reticulum, but animal cells can have endoplasmic reticulum. the cytoplasm of plant cells has mitochondria, vacuoles, and chloroplasts.

Explanation:

1. Mitochondria break down sugar to release energy (cellular respiration), not store sugar. Vacuoles can store substances but not break down sugar for energy release. So the first statement is false.
2. The cell - membrane and cell - wall of a plant cell act as barriers separating the cell from its surroundings. This statement is true.
3. Both plant and animal cells have endoplasmic reticulum. So the third statement is false.
4. The cytoplasm of plant cells contains mitochondria (for energy production), vacuoles (for storage), and chloroplasts (for photosynthesis). This statement is true.

Answer:

The cell membrane and cell wall separate a plant cell from its surroundings.
The cytoplasm of plant cells has mitochondria, vacuoles, and chloroplasts.
