Photosynthesis

& Cellular Respiration

What is Photosynthesis?

The process of capturing and transforming the energy of sunlight into chemical energy

Who Uses This Process?

Plants (Plant Cell)

Some Bacteria's

Protists They make their

own food!

Which Organelle inside the

plant cell performs

photosynthesis?

Organelle: Chloroplast

Why is it Green?

Pigment called chlorophyll

Chlorophyll – Contains photosynthetic membranes

Converts light energy to chemical energy

Chlorophyll Why are plants green?

Light-absorbing chlorophyll molecules are present in thylakoid discs that fill the CHLOROPLAST

Out of the entire spectrum of colors that makes up white light, chlorophyll absorbs both the red and blue.

Green is reflected away, and is the color you observe.

What do you need for

photosynthesis to take

place?

Sunlight

Carbon Dioxide (Co2)

Water ( H2O)

Oxygen

Glucose

Photosynthesis Equation

How does the water, carbon dioxide and

sunlight enter the plant?

Guard Cell

Guard cell walls have cellulose

This causes the bow in the

Guard cell and stomate opens

What is Photolysis?

This part of photosynthesis occurs in the granum of a chloroplast where light is absorbed by chlorophyll;

A type of photosynthetic pigment that converts the light to chemical energy.

This reacts with water (H2O) and splits the oxygen and hydrogen molecules apart.

From this dissection of water, the oxygen is released as a by-product
