Concepts to know (multiple choice on the test)
1. cells are the building blocks of life
2. the nucleus controls all functions of the cell
3. the most numerous organisms on earth are bacteria
4. humans are classified as being vertebrates and mammals
5. nonvascular plants lack tubes for carrying water and food
6. vascular plants have vines and tubes
7. the cells of bacteria are different from all other cells because they do not have a nucleus
8. be able to look at a picture to tell if something is an arachnid, insect, crustacean, or arthopod
Short Answers
1. Be able to describe the difference between a vascular and non vascular plant:
Vascular plants have tubes that carry water and food. Nonvascular plants are smaller and do not have
tubes that carry water and food.
2. Some bacteria carry disease, but not all bacteria are harmful. List two ways bacteria are helpful: The
help us digest food, they can be used to clean up oil spills, they make oxygen
3. Know that a fern is a vascular plant that has spores on the underside of leaves
4. Why don’t ferns produce flowers? Not all vascular plants are flowering plants. There are two
categories of vascular plants that do not produce flowers: cone-bearing plants and ferns.
