Unit 2Structures of Living Things

Lesson 1How do organisms

transport materials?

Cells as Building Blocks• A cell is the basic unit of structure and function in

living things.• Every living thing is made up of cells.• Jobs that our cells do:

– Break down food– Carry oxygen to other cells– Carry away waste materials

Cell Structures & Functions• Plant Cell • Animal Cell

Tissues• Most of your body is made of muscle

blood.

• Nervous tissue makes muscles contract.

Tissues work together in an Organ.

• Stomach: breaks down food.

• Heart: pumps blood to the body.

• Lungs: take in oxygen.

All of these work together to form an

organ system.

Circulatory System• Made of: Heart, blood vessels, &
