PHOTOSYNTHESIS 7 TH GRADE SCIENCE CHAPTER 4, LESSON 1

Thursday November 20, 2014 Agenda- photosynthesis Warm-up Review for benchmark test:  What is the powerhouse of the cell called?  What is the highway of the cell?

VOCABULARY Photosynthesis Autotroph Heterotroph Pigment Chlorophyll stomata Define Draw picture

Sources of energy Where do organisms get energy? All energy comes from the sun Directly-organisms make their own food Indirectly- organisms eat organisms that make their own food

Photosynthesis What are the 2 stages of photosynthesis? 1. capturing the sun’s energy 2. using energy to make food

photosynthesis What happens during stage 1 (capturing the sun’s energy)? Occurs in the leaves Chlorophyll in chloroplasts captures energy from sunlight

November 21, 2014 Agenda-photosynthesis Warm up-explain how the energy you get from your thanksgiving dinner came directly or indirectly from the sun. Review What is a pouch that stores food and water for a cell? What part of a cell might you call a mailroom?

photosynthesis What happens during stage 2 (using energy to make food)? Sugar is made (food) Needs sunlight, water and carbon dioxide Water enters roots and is sent to the leaves. Carbon dioxide enters the stomata in the leaves. Water and carbon dioxide enter the chloroplasts. Sugar and oxygen are made.

Monday December 1, 2014 Agenda-benchmark review Review In a plant cell, what captures energy to produce food? What are the 3 parts of the cell theory? What is the control center of the cell?

Tuesday December 2, 2014 Agenda-benchmark review; benchmark test tomorrow Warm-up Write a paragraph of at least five sentences describing Viruses and Bacteria, how they are spread, preventions, treatments, and types of each.

Wednesday December 3, 2014 Benchmark test Review notes

Thursday 12/4/14 Agenda-photosynthesis What are the ingredients for the process of photosynthesis? What do you get at the end of photosynthesis?

photosynthesis What is the photosynthesis equation? 6 molecules of carbon dioxide plus 6 molecules of water plus light energy yields (gives) 6 molecules of oxygen plus 1 molecule of sugar.

Photosynthesis reaction

photosynthesis Why do plants do photosynthesis? Plants use the sugar to carry out their functions.

photosynthesis Why is photosynthesis good for us? When you eat food from plants you are eating the stored sugar. Oxygen is released through stomata.
