select all the true statements.
in plant cells, chloroplasts make sugar using sunlight, and mitochondria break down the sugar to release energy.
a plant cell does not have a golgi, but an animal cell can have a golgi.
the nucleus of a plant cell contains the chromosomes but not the chloroplasts.
in plant cells, chloroplasts make sugar using sunlight, and vacuoles store the sugar.
submit

Explanation:

• First statement: Chloroplasts perform photosynthesis (make sugar using sunlight) and mitochondria perform cellular respiration (break down sugar to release energy). This is correct.
• Second statement: Both plant and animal cells have Golgi apparatus. So this statement is false.
• Third statement: The nucleus contains chromosomes (genetic material) and chloroplasts are organelles outside the nucleus. This is correct.
• Fourth statement: Chloroplasts make sugar, but vacuoles mainly store water, ions, etc. and not sugar (sugar is transported and stored in other forms like starch in some plant tissues). So this statement is false.

Answer:

• First statement: In plant cells, chloroplasts make sugar using sunlight, and mitochondria break down the sugar to release energy.
• Third statement: The nucleus of a plant cell contains the chromosomes but not the chloroplasts.
