The document discusses two forms of plant reproduction: sexual reproduction which involves meiosis and fertilization, and asexual reproduction or vegetative propagation which involves mitosis. It provides details on sexual reproduction in angiosperms using flowers, conifers using cones, and ferns using spores. The document also lists different structures used in vegetative propagation like tubers, rhizomes, stolons, bulbs, and corms.

4. Sexual
reproduction
occurs in many
kinds of plants
in different
ways. Some
plants form
pollen that
fertilizes eggs in
the flower or
cone, others
produce spores.

5. Angiosperms reproduce using their flower structure:

6. The petals attract insects and
birds to encourage pollination.
The stigma, style, and ovary
make up the female structure
– the pistil. The ovary
houses the ovules (eggs) before
and after fertilization
The anther and filament make up
the male structure – the stamen
- that produces the pollen.

7. When the ovary ripens it becomes fruit – that contains the seeds.

8. Seed

9. In
conifers,
the plant
produces
male and
female
cones –
male
cones
contain
pollen,
while
female
cones
bear eggs.

10. In ferns, sexual reproduction takes place by the
production of spores that fertilize eggs in alternating
generations of the plant’s life cycle.

11. Asexual
Reproduction

12. Most plants can also reproduce new
plants through asexual reproduction
– also called vegetative propagation –
where new plants grow from a piece
of the old plant.
Some plants have special structures
for vegetative propagation . . .
