Question

Answer the following in a 4th graders response 2 sentences each.

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 covers the outside and the inside surfaces of the body. It protects you, keeps germs out, and lines organs like the stomach.

3. The skeletal system gives your body shape and support and protects important organs like your brain and heart. Bones also help you move with muscles, store minerals, and make blood cells inside them.

4. The muscular system (working with the bones) supports the body and lets it move. Muscles pull on bones so you can walk, run, and pick things up.

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

6. Both epithelial and muscle tissues are groups of cells that help the body work, but they do different jobs. Epithelial tissue covers and protects surfaces with tightly packed cells, while muscle tissue has cells that contract to make the body move.
