Question

select all the true statements.

1. both plant and animal cells can have a nucleus.
2. the nucleus of an animal cell contains the chromosomes but not the lysosomes.
3. in an animal cell, the endoplasmic reticulum helps ribosomes make proteins, and the golgi sends proteins to different parts of the cell.
4. the nucleus of an animal cell contains the vacuoles but not the chromosomes.

Explanation:

1. Both plant and animal cells are eukaryotic, so they have a nucleus.
2. The nucleus of animal cells holds chromosomes; lysosomes are cytoplasmic organelles, not in the nucleus.
3. Ribosomes on rough ER synthesize proteins, and the Golgi apparatus modifies and transports proteins to other cell parts.
4. Animal cell nuclei contain chromosomes, not vacuoles (vacuoles are cytoplasmic).

Answer:

• Both plant and animal cells can have a nucleus.
• The nucleus of an animal cell contains the chromosomes but not the lysosomes.
• In an animal cell, the endoplasmic reticulum helps ribosomes make proteins, and the Golgi sends proteins to different parts of the cell.
