Unit 3 Test: Study Guide
Living Organisms
1. What are the building blocks of all living organisms? cells
2. What are the 5 characteristics that makes something living? Made of cells, grow and develop, use
energy, respond to their environment, reproduce
3. What is the difference between unicellular and multicellular organisms? Unicellular-simple one celled,
multi-more than 1-complex
4. What is the difference between an autotroph and heterotroph? Autotroph-plants make their own
energy, heterotroph-get their energy from other organisms-consuming/eating
5.
Unicellular
Organism
Plant/Animal or Both?
Drawing of Organism
How Do They Move
Amoeba
animal
Pseudopods (false feet)
Euglena
both
Flagellum (also moves food into
the mouth)
Paramecium
animal
cillia
Volvox
plant
flagellum
Plant and Animal Cells
6. What does the CELL THEORY state? All living things are made of one or more cells
7. How do plant and animal cells differ? Plant cells have chloroplast (energy from the sun), plant has one
large vacuole, plant has a cell wall (protect/gives it structure)
8.
H
Digests cell parts and food
A. Mitochondria
D States that all living things are made of cells
B. Cell Wall

C
Protects the cell
Packages and secretes proteins
Fluid material that contains the organelles
Stores waste and food
Supplies energy for the cell
Transports proteins throughout the cell
Controls all the functions of the cells
Contains chlorophyll/allows photosynthesis to occur
Cell Cycle (including Mitosis)
9. How did we use a hamburger to show the stages in the cell cycle?
C. Chloroplast
D. Cell Theory
E. Cytoplasm

10. What are the six stages of the CELL CYCLE in order? Interphase, prophase, metaphase, anaphase,
telophase, cytokinesis
11.
Stage of
Mitosis
What Happens in Each Stage?
Prophase
nucleus PREPARES to split
Metaphase
Chromatids line in the MIDDLE
Anaphase
Chromatids pull APART
Telophase
TWO nuclei
Cell begins to split
Diagram Each Stage
12. Which is the longest stage in the CELL CYCLE? interphase
13. What is the end result of the cell cycle? Two identical cells (Cytokinesis)
14. What are the FOUR reasons why cells divide? Reproduce, grow, replace, repair
Body Systems
15. What are the four types of tissues? Connective, muscular, epithelial (skin), nervous
16. What is the correct order of the make up living organisms? Cell, tissue, organ, organ system, organism
17. Which two systems send messages to the rest of the body? nervous/endocrine
18. Which two systems work together to move oxygen throughout the body? circulatory/respiratory
19. What is the major organ of both the circulatory and muscular system? heart
20. Which two systems move the body? Muscular/skeletal
21. Which organs are in the digestive system? Small intestine, stomach, esophagus
22. Which organ digests the most materials? Small intestine
23. What is homeostasis and how does it relate to the body? Balance in the body (ex. Sweat allows body to
cool and maintain its temperature)
24. Which is the largest organ of your body? Skin (liver is the biggest IN your body)
25.
