Life Science Study Guide
1. All vertebrate animals have backbones.
2. These two cells are different in function by the microorganism performs all functions within a single
cell, while the muscle cell performs a certain function within an organism.
3. The function for the cell membrane is it controls what enters and leaves the cell.
4. A biologist made a table to show the characteristics of six organisms. The Internal Structure
characteristic should be used to classify the organisms as vertebrates or invertebrates.

5. Ms. Lee asked her students to draw pictures of invertebrates.
Students A and D are correct, because both organisms have
backbones.
6. Gregor Mendel was a scientist who lived in the 1800s. He studied inherited traits in pea plants. The
plants with green seeds came from parents with green seeds could have been one of the observations
about inherited traits that he recorded.
7. Sickle cell anemia is a disease caused by the presence of a trait that changes the shape of the red
blood cells. The genes of the parents of a child with sickle cell anemia would BEST help a researcher
understand if this is an inherited trait.
8. Chloroplast is the cellular structure is found in plants, but not in animals.
9. New bacteria come from other bacteria.
10. Mold on fruit is considered a harmful microorganism.
11. When we forget to wash our hands, or don't wash them properly, we are spreading harmful
microbes to other people, or giving them to ourselves by touching our eyes, mouths, noses or cuts on
our bodies.
12. Amphibians are cold-blooded, live part of their lives in water and part on land, and go through
metamorphosis.
13. In the 1670s, Antony Leeuwenhoek discovered microorganisms in the human mouth. Later these
microorganisms were determined to cause dental plaque, which is harmful to teeth. Another way
microorganisms can be harmful is that microorganisms break down meat before it is eaten.
14. A teacher showed her students a picture of a tree that does not lose all its leaves every year.
This tree should be classified as non-flowering.
15. A group of science students were asked to draw pictures of animals they observed on a field trip to a
zoo. All of these animals be would be classified as
vertebrates because they all hav. e backbones.
16. A girl observed her younger brother and listed the behaviors she saw. Reading is a learned behavior.
17. Plants that do not have specialized tube-like tissues to transport water from cell to cell are
nonvascular.
18.
is a plant cell.
19. It would not be good for your health to kill all of the bacteria in your body. Many bacteria in your
body are beneficial. These beneficial bacteria help your body perform physiological functions, such as
digestion.
20. The function of the nucleus is the same in both kinds of cells because it controls the activities of the
cell.
21. Having blue eyes is an inherited trait.
22. A microscope is best used to observe cells and their structure.
23. An apple tree is an angiosperm.
24. Label the parts of each cell. Tell if the cell is a plant or animal cell. (10 Pts.)

25. Define the difference between learned behaviors and inherited traits.
