Fill in the blanks:
_______; Tissues; _________; Organ Systems; _________ | Cells; Organs; Organisms |
Name an organ system, and describe its organs and function. | **Answers will vary**
(Ex.) One example of an organ system is the nervous system. Its main organs are the brain, spinal cord, and neurons (aka nerves.) The function of the system is to control the body's actions, and also store data. |
Name two organelles that are exclusive to the plant cell. | 1) The cell wall
2) Chloroplast |
Describe the function of the lysosome. | The lysosome is an organelle in both the plant and animal cells. It is responsible for breaking down waste, nutrients and other things. |
Name an organelle, and its function. | **Answers will vary**
(Ex.) The nucleus is one of the organelles in a cell. It directs the activities in a cell, and controls what happens to the cell. |
What is the function of the excretory system? | The excretory system is the system in charge of getting rid of waste in the body. It is also in control of water in the body. |
What two parts of the plant cell help support it and maintain it’s shape? | 1) Vacuole
2) Cell wall |
What organelle provides most of the energy for the cell? | Mitochondria |
Compare and contrast cells and tissue. | Cells and tissue are both alike and different. They are different because the cell is the smallest unit of an organism, while tissue is not. They are alike because they can both be specialized in certain functions. |
Which way does blood flow in veins? Arteries? | Blood flows to the heart in veins, and away from the heart in arteries. |

The ___________ controls the body’s actions and reactions. | Nervous system |
The ___________ is composed of all of the bones in the body. It gives the body shape, and the ability to move. | Skeletal system |
The ___________ is composed of all of the muscles in the body. It gives the body shape, and the ability to move. | Muscular system |
Name five organelles that are in both pant and animal cells. | (Ex.) Nucleus, ER, Golgi apparatus,lysosomes, vacuoles, cytoplasm, microtubules, cell membrane, mitochondria, etc. |
Give an example of a type of tissue in the body. | (Ex.) Nerve tissue, skin tissue, bone tissue, etc. |
The ___________ controls all of the hormone levels and actions in the body. | Endocrine system |
