1. Pollination of Flowers
A Biology Investigatory Presentation

2. Introduction
• Pollination is the process by which pollen is
transferred from the male part (anther) of a
flower to the female part (stigma) of the same
or another flower. It is an essential step in the
reproduction of flowering plants, leading to
fertilization and seed formation.

3. Types of Pollination
• 1. Self-Pollination: Occurs when pollen is
transferred to the stigma of the same flower
or another flower on the same plant.
• 2. Cross-Pollination: Occurs when pollen from
one flower is transferred to the stigma of a
flower on a different plant of the same
species.

4. Agents of Pollination
• Pollination is aided by various agents:
• • Wind (Anemophily): Lightweight pollen
carried by wind.
• • Water (Hydrophily): Pollen travels through
water bodies.
• • Insects (Entomophily): Bees, butterflies, and
others carry pollen.
• • Birds (Ornithophily): Birds transfer pollen
while feeding on nectar.

5. Importance of Pollination
• • Ensures fertilization and formation of seeds
and fruits.
• • Maintains plant biodiversity and ecosystems.
• • Crucial for food production and agriculture.
• • Supports natural selection and evolution in
plants.

6. Conclusion
• Pollination is a vital natural process ensuring
plant reproduction, biodiversity, and food
security. Understanding its mechanisms and
importance helps in conserving pollinators
and maintaining ecological balance.

7. Extended Understanding of
Pollination
• Pollination plays an integral role in sustaining
ecosystems and agriculture across the world.
Without effective pollination, many crops such
as apples, sunflowers, and almonds would fail
to produce fruits or seeds. Bees, butterflies,
and other insects are among the most
important pollinators, responsible for
transferring pollen between flowers, thus
ensuring genetic diversity and plant
reproduction.
