Question

Answer the following in a 3rd graders response 2 sentences each. In your own words

2. Which type of tissue covers the surface of the body?
3. What are the functions of the skeletal system?
4. Which organ system supports the body and allows it to move?
5. Explain how form and function are related in human cells. Include examples.
6. Compare and contrast epithelial and muscle tissues.

Answer 1

2. Epithelial tissue, called epithelium, covers the outside of the body and the inside of organs. It makes skin and lines places like the mouth and stomach.

3. The skeletal system gives the body shape and support so we can stand up and protect our organs. It also helps us move with muscles and makes blood cells inside some bones.

4. The skeletal and muscular systems work together to support the body and let it move. Bones hold the body up and muscles pull on the bones so we can run, jump, and play.

5. Form means the shape of a cell and function means what it does, and the shape helps it do its job. For example, red blood cells are smooth and round to carry oxygen, nerve cells are long to send messages, and muscle cells are long and strong to help move.

6. Epithelial tissue covers and protects the outside and inside of the body, while muscle tissue can contract to make the body move. Both are made of cells and help the body, but epithelial is thin and protective and muscle is stretchy and strong.
