2. What is photosynthesis?
 Photosynthesis is the process by which green plants
makes food in the presence of sunlight, in order for
photosynthesis to take place in green plants they need
water and minerals from the soil, sunlight and air.
 air(carbon dioxide).

4. The process of photosynthesis
 Plants acquire carbon dioxide from the air. It goes
through the pores in the leaves called the stomata,
water is absorbed from the soil by the roots. This water
is taken by the xylem vessels and is being distributed
to other parts of the plant.

5. Photosynthesis in green plant
 Photosynthesis takes place in the chloroplast of a
green plants. The chloroplast contains a green pigment
called chlorophyll that trap the energy from the sun.
The plant use this energy to make food.
Photosynthesis takes place in green leaves but it can
occur in any area of the plant that is green. After
photosynthesis food is stored in the plant ,example
root, stem, and leaves. Oxygen is release into the
atmosphere ,while the manufactured food is being
transported by the phloem vessel.

6. The Plant Transport System
 Plants have two different types of transport tissue.
Which include the xylem and phloem. Xylem
transports water and solutes from the roots to the
leaves, phloem transports food from the leaves to the
rest of the plant. Transpiration is the process by which
water evaporates from the leaves, which results in
more water being drawn up from the roots. Plants have
adaptations to reduce excessive water loss.

7. Functions of the vessels in plants
Xylem vessels Phloem vessels
 It absorb water from the soil
through root hair cells.
 Water is transported up the
stem to the leaves of a plant.
 Water evaporates from the
leaves by a process called
transpiration.
 It is consist of dead cells.
 It have a thick cellulous wall.
 It transport food substances
from the stem to growing
tissues of the plants.
 It stores food in the tissues of
plants.
 It consist of columns of living
cells.

10. Photosynthesis
Advantages Disadvantages
1. All food comes from plant
whether directly or
indirectly.
2. Oxygen which is needed by
animals is produce as a
result of photosynthesis.
3. The level of carbon dioxide
is reduce by photosynthesis.
1. Photosynthesis cannot be
done in shade.
2. Photosynthesis can not be
done over night.
