Photosynthesis

Grab the “P-R Worksheet” document in Moodle and open in Notability.

Getting StartedGetting Started First, draw a symbol to represent each item in

the grid. Next, cut each item out, using the scissors,

and put on the correct side of the tree for PHOTOSYNTHESIS.

***Think about what you already know about plants!

Read text book page 94 and answer the questions on your worksheet.

Chemical Equation for PhotosynthesisChemical Equation for Photosynthesis

carbon dioxide + water + light energy glucose + oxygen

• Photo = light• Synthesis = combining parts to make something

•Photosynthesis = combining water and carbon dioxide (with the help of the sun) to make sugar!

Importance of Photosynthesis:Importance of Photosynthesis:1. FOOD•Produces food for almost all organisms.

– ChallengeChallenge – Can you think of a food that is NOT somehow traced back to a plant?

2. “FRESH” AIR•Removes carbon dioxide from, and adds oxygen to, the atmosphere.

Again, draw a symbol to represent each item in the grid.Next, cut each item out, using the scissors, and put on the correct side of these organisms for RESPIRATION.

Respiration (the whole truth!)Respiration (the whole truth!) Since plants AND animals have living cells,

they both need to do respiration to make energy for those cells.

Plants just make the food that their cells eat!

Chemical Equation for RespirationChemical Equation for Respiration

oxygen + glucose carbon dioxide + water + ENERGY

(ATP)

Respiration = the process of breaking down glucose (in the presence of oxygen) to make ATP ENERGY!

Your task

Read text book page 95 and answer the questions on your worksheet.

Importance of Respiration:Importance of Respiration:

• ENERGY (ATP) is like the fuel of the cell.

• ENERGY (ATP) allows cells to build and move things around to keep the organism alive.

Remember, ALL living things need and use ENERGY (ATP).
