- 12. Multiple Choice
Which of the following best describes why a cell would not be able to reproduce if its nucleus were damaged?
The nucleus is responsible for creating the energy used to perform cell division.
The nucleus is responsible for housing the genetic information needed for cell division.
The nucleus is responsible for letting the materials in that are needed for cell division

- 13. Multiple Choice
Which organelle may often be referred to as the "gate keeper" because it controls what goes in and out of the cell?
the cytoplasm
the nucleus
the cell membrane
the mitochondrion
- 14. Multiple Choice
Which statement best compares multi-celled organisms to single-celled organisms?
Multi-celled organisms always get energy differently than single-celled organisms.
Single-celled organisms carry out fewer life functions than multi-celled organisms.
Single-celled organisms are always larger than multi-celled organisms, but multi-celled organisms always perform more functions.
Multi-celled organisms have many cells that perform different functions, and single-celled organisms perform all functions within one cell.
- 15. Multiple Choice
Multi-celled organisms have many cells that perform different functions, and single-celled organisms perform all functions within one cell.
Animal cells do not contain cytoplasm because animals use lungs to conduct respiration.
Animal cells do not contain chloroplasts because animals do not conduct photosynthesis.
Animal cells do not have mitochondria because animals do not produce their own energy.
Animal cells do not have cell membranes because animals use bone structures for support.
- 16. Multiple Choice
Vacuoles are cell structures that are sometimes compared to warehouses. They have the ability to store things such as water and nutrients, and in some cases provide rigidity for the cell.

a cactus cell
a human cell
a worm cell
a mushroom cell
