This document discusses photosynthesis and defines it as the process by which plants convert light energy from the sun, carbon dioxide, and water into chemical energy stored as glucose. It states that photosynthesis takes place in chloroplasts, which contain the green pigment chlorophyll. The key components needed for photosynthesis are light, carbon dioxide, and water. The equation for photosynthesis is provided as carbon dioxide + water + light energy → glucose + oxygen. Structures involved in photosynthesis like the chloroplast, thylakoid membrane, and photosystems are also outlined.

1. PHOTOSYNTHESIS
How plants make their own food

2. LESSON OBJECTIVES
 Defining photosynthesis
 Know what the plant needs in order to
photosynthesize.
 Know the equation for photosynthesis
 Describe how the process takes place
 Name the organelle and green pigment required
for photosynthesis.

3. WHAT IS PHOTOSYNTHESIS
 Photosynthesis is the process by which
organisms convert light energy into
chemical energy in form of reducing power
( as NADPH or NADH) or ATP, and use this
chemicals to drive Carbon Dioxide fixation
and reduction to produce sugars.

4. What photosynthesis needs
 These are the things a plant needs for
photosynthesis.
 1. water
2. Carbon dioxide
3 light energy from the sun.

5. EQUATION FOR THE PROCESS
CO2 + 2 H2O + → [CH2O] + H2O + O2
Carbon Dioxide + water = oxygen
+ water + glucose

6. PHOTOSYNTHESIS PROCESS

7. WHERE DOES PHOTOSYNTHESIS TAKE
PLACE?
 Photosynthesis takes place inside plant cells
in small things called chloroplasts.
Chloroplasts (mostly found in the mesophyll
layer) contain a green substance called
chlorophyll.

8. STRUCTURE OF PLANT CELL

9. STRUCTURE OF CHLOROPLAST
 Chloroplast is the structure that is found in plant cell only, it contains a
green pigment called chlorophyll.
 Function of chlorophyll
 Chlorophyll is vital for photosynthesis, which allows plants to absorb energy
from sun light.
 Chlorophyll molecules are specifically arranged in and around photosystems
that are embedded in the thylakoid membranes of chloroplasts. In these
complexes, chlorophyll serves two primary functions. The function of the vast
majority of chlorophyll (up to several hundred molecules per photosystem) is
to absorb light and transfer that light energy by resonance energy transfer to
a specific chlorophyll pair in the reaction centre of the photosystems. The
two currently accepted
