1. Aim: How do plant cells photosynthesize to make food? DO NOW: 1. What color do chloroplasts, in plant cells, have? Why? 2. What is the purpose of this pigment, in chloroplasts, in plant cells?

2. Organelle? Chloroplasts of plant cells

3. Photosynthesis CO 2 + H 2 O + sunlight  C 6 H 12 O 6 + O 2 Chemical Equation Carbon Dioxide + Water + Sunlight  Oxygen + Glucose Word Equation __________________________________________ Q: What are the reactants & products in this chemical reaction?

5. Guard Cells & Stomates GUARD CELLS in plant cells control the opening & closing of the STOMATES (pores) in the leaves of plants Important to prevent too much water from being lost on a hot day Carbon dioxide is also allowed in, by way of these guard cells & stomates

7. Xylem & Phloem The “circulatory system” of plants Tissues, made of cells, that are involved in transport & which are located in vascular bundles Xylem cells transport water & dissolved minerals up the plant Phloem cells transport nutrients, like glucose sugars, & other molecules, created by plants, down the plant Tree sap comes out of phloem tissue Xylem dies and has to be created again, but phloem is always alive!

8. Cross-Section of a Plant Stem
