Question

select the one true statement.
mitochondria break down sugar to release energy that an animal cell can use.
plant cells can have a nucleus but do not have chloroplasts.
the cell membrane stores nutrients, water, and waste in a plant cell.

Explanation:

• Mitochondria are the powerhouses of the cell. They break down sugar (through cellular respiration) to release energy (in the form of ATP) that an animal cell (and plant cell) can use.
• The cell membrane controls what enters and exits the cell. It is the vacuole that stores nutrients, water, and waste in a plant cell.
• Plant cells that are not involved in photosynthesis (like root cells) can have a nucleus but do not have chloroplasts. But the statement “Plant cells can have a nucleus but do not have chloroplasts” is too broad. All plant cells have a nucleus, and only some (non - photosynthetic) lack chloroplasts. The more accurate and general - in - context (for a basic cell biology question) correct statement is about mitochondria.

Answer:

Mitochondria break down sugar to release energy that an animal cell can use.
