Cells/Body Ststems

Use these to review information about cells and the human body systems.

What are the three parts of cell theory? 1) Cells are the smallest unit of an organism. 2) Cells come from other cells. 3) Cells are a part of all living things.
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.
Name the type of muscle that is involuntary, and exclusive to the heart. Cardiac muscle.
Name the type of muscle that is involuntary, and works in things like the digestive system. Smooth muscle.
Name the type of muscle that is voluntary, and works to move parts of the body. Skeletal muscle.
Where are many blood cells produced? Bones.
_____________ keep bones held together. Ligaments
_________ in the system connect the bones to muscle, so they can work together. Tendons
_________ are groups of cells that are specialized in a certain process or action. Tissues
__________ muscle is muscle that moves without you having to think about it. Involuntary
__________ muscle is muscle that you control when you are thinking about it. Voluntary
_____ do certain things for the body, and each is made up of a different type of tissue. Organs
The ___________ takes in the food that we eat and breaks it down into fuel that our body can use. Digestive system
The ___________ moves oxygen around the body (through the blood) for all the cells to use. Circulatory system
The ___________ is the system responsible for breathing, letting oxygen into the body and carbon dioxide out. Respiratory system
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
