2. plants make their own food

3. cells with membrane organelles

Explanation:

brainliest please

1. A

2. B

3. A

Explanation:

1. Heterotrophs are organisms that cannot make their own food and instead rely on others for energy.  Heterotrophs are not individual cells , nor or they always single-celled. So, the answer is A.

2. Plants and animals have many similarities (both are eukaryotic and both are multicellular), but they also have key differences that make them unique from each other. One of these is that plants are autotrophs, which means that they can make their own food. So B is the answer.

3. Eukaryotes are organisms with a nucleus and membrane-bound organelles. This is in contrast with prokaryotes, which do not have these things. The answer is A.
