The document discusses the life processes of plants which include nutrition, interaction, and reproduction. It classifies plants into three types: grass, bushes, and trees. It also describes the male and female reproductive organs of flowers and the process of pollination and fertilization leading to the production of fruits and seeds.

2. Plants give us: food, medicine, clothes, and the
oxygen we need to live.
Plants have three life processes: Nutrition,
interaction and reproduction.
We can classify plants into: Grass, bushes and
trees.

Animals eat the fruit and the
seeds are in the feaces

places. It’s means that a
new plant grows from
each seed.

4. • Animal pollination is carried out
by birds and insects. Colorful
petals attract animals to a flower
to drink a sweet liquid called
nectar. Pollen from the stamens
stick to the animal’s body.
• Wind pollination is used by
plants which don’t have colorful
petals to attract animals.

5. 4. Chloroplast in the
leaves help to make
sap or glucouse.
3. The leaves mix
water, minerals,
sunlight and carbon
dioxide to make sap
or glucousse.
5. The leaves have holes called
stomata, that absorb CO2 and release
oxygen to the atmosphere.
2. Water and
minerals rise up
the stem through
some vessels
called xylem and
reach the leaves
1. The roots fix the
plant to the ground
and absorb minerals
and water from the
soil.
6. Sap or glucouse
circulates from the
leaves to the rest of
the plant.
7. Remember!
Photosynthesis is the
process in which plants
use water, minerals, CO2
and sunlight to make
their own food. This also
means that plants
release oxygen to the
atmosphere.
