Cellular Processes

Brainstorm: What must cells do to stay alive?

Four Cell Processes 1. Photosynthesis 2. Cellular Respiration 3. Waste elimination (Diffusion and osmosis) 4. Mitosis

- Plants use _______________________, ____________________, ____________________to make simple sugars like ________________. _____________ and ______________ are released. EQUATION: WHERE: - Photosynthesis occurs in the _____________________. The process in which plant cells convert light energy into food. HOW: WHAT:

Cellular Respiration WHAT: The process which cells use to make energy. HOW: All organisms break down ___________and _____________, into _________________, ___________________________, releasing ___________________ (ATP). The cell uses this ATP (__________________) to build, repair, and reproduce cells. EQUATION: WHERE: - Respiration occurs in the _________________________.

We can summarize these processes with chemical equations. Photosynthesis: Cellular Respiration:

1.If a cell does not undergo certain cellular processes, what would happen? 2.Plants use light energy from the sun to undergo this cellular process? 3.Plants combine carbon dioxide and what to make products? 4.What products do plants produce during photosynthesis? 5.What happens to the sugars produced by plants? 6.All organisms, including plants and animals, undergo this cellular process to release energy. What is it? 7.What do the cells use this energy to do? 8.Which two cellular processes are opposite each other? On a separate piece of paper, write the question, highlight the question, answer the question.

Waste Elimination What: The cell uses diffusion to get rid of waste products, like CO2. How: During diffusion, materials move from an area of high concentration to an area of low concentration. Where: Across cell membrane.

A special type of waste elimination is...

MITOSIS What: Cell reproduction needed for growth, repair, and cell replacement. How: Cell makes exact copies of itself. One parent cell divides into 2 identical daughter cells.
