Presentation transcript:

Active Transport S7L2: Students will describe the structure and function of cells, tissues, organs, and organ systems. a. Explain that cells take in nutrients in order to grow and divide and to make needed materials.

What is active transport? When an input of energy is required to move materials through a cell membrane Two types: Endocytosis and Exocytosis

What is endocytosis? Process of taking materials into a cell by surrounding it with the cell membrane Materials enter

What is exocytosis? Process of releasing materials out of a cell Materials Exit
