Sexual Reproduction
Most plants grow from seeds
These plants have parts that are
responsible in the making of seeds.
These seed-making parts of plants are
found in the flowers.

Ovules
An egg cell is
formed in the
ovule.
The ovules, after
fertilization, will
develop into seeds
and the ovary
surrounding it
becomes the fruits
in most plants.

What is the Role of
Pollination?
 One important function
of the flower is to
produce seeds. but,
how?
If seeds are to be produced, the
pollen grains from the anther must
land on the stigma.
What is pollination?
 Is the first step in the process of
development of seeds in plants.
 Occurs mainly by wind and by
animals such as insects and birds.
Two types of Pollination
Self-pollination
 When pollen from
a plant’s anther is
transferred to that
same plant’s
stigma.
Cross-pollination
 When pollen from
a plant’s anther is
transferred to
another plant’s
stigma.
Fertilization and development of the
seed
Fertilization – is the union of sperm cells and egg
cells.
 after fertilization the ovules gradually transform
into mature seeds and the ovaries into fruits.
