Science Module A Chapter 1 Study Guide
1. What is a life process and give a few examples? A function that a living thing performs to stay
alive and reproduce. Take in materials, grow and develop, release energy, react to
surroundings, give off wastes, reproduce.
2. The basic unit that makes up all living things is called a cell.
3. Cells are so small that you can only see them with a microscope.
4. What two parts does a plant cell have that an animal cell doesn’t and what do those parts do?
Cell wall- gives plants their shape.
Chloroplast- where the plant makes its food.
5. The control center of a cell is called its nucleus.
6. The power sources of a cell are called its mitochondria.
7. The part of a cell that acts like a skin and holds a cell together is called a cell membrane.
8. The part of the cell used for storage of food, nutrients, and waste is called a vacuole.
9. The jellylike material that fills up cells is called cytoplasm.
10. Any living thing that can carry out life processes on its own is called an organism.
11. A special part of an organism that performs a specific function is called an organ.
12. How are simple organisms different from people? Simple organisms do not have organs that
carry out specific functions.
13. A group of similar cells that work together are called tissue.
14. A group of organs that work together to carry out life processes is called an organ system.
15. What is an example of an organ system? Digestive system, nervous system
16. Who is given credit with discovering the cell? Robert Hooke
17. An undeveloped plant sealed in a protective coating is called a seed.
18. The part of the plant where seeds are produced is called the flower.
19. The part of the plant where food is made is called the leaf.
20. What do plants need in order to make their own food? What gas do plants give off as a waste
product? A plant needs water, sunlight, and the carbon dioxide in air to make food. Plants
produce oxygen as a waste product.
21. The part of the plant that carries water and nutrients from the roots to other parts of the plant is
called the stem.
22. The part of the plant that takes in water and nutrients from the ground is the root.
23. Do all plants have the same parts? Why or why not? No; Plants can have different kinds of roots,
stems and leaves. Some plants are flowering and others are non-flowering.
24. A green material that can trap energy from the sunlight is called chlorophyll.
25. Describe the process of photosynthesis.
1} Plants take in carbon dioxide from the air and water from the ground.
2} Inside the leaves, in the chloroplasts, the carbon dioxide and water are changed into the
plants food (sugar).
3} The stem carries the sugar to all parts of the plant.
4} The plant also makes oxygen, but the oxygen is released back into the air.
