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.
Parts of a Flower
Sepals
Petals
Receptacle
Pistil
Stamen
Stamen
The stamen (plural stamina or stamens) is the pollen-producing reproductive organ of a flower.
Filament- Supports the Anther
Anther- Produces Pollen Grains
Pistil
The ovule producing part of a flower.
The ovary often supports a long style, topped by a stigma. The mature ovary is a fruit, and the mature ovule is a seed. Stigma: The part of the pistil where pollen germinates.
Peduncle
The stalk of a flower.
Types of Flowers
Complete Flowers- have both male and female parts
Incomplete Flowers- have either male or female parts but not both.
Pollination
is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds.

How Are Flowers Useful to Us?
Flowers are not just beautiful to look at,
but they also serve a vital role in our ecosystem.
Flowers help our ecosystem flourish and attract a plethora of life to the area and facilitate the expansion of our environment. If flowers are cut down or destroyed before pollination can occur, that particular species has a high chance of dying off in that area. In addition, local wildlife will also vanish in that area since they would have no food. Flowers help keep the ecosystem growing and provide new plant life, as well as help sustain local insects and birds.

Solution
Sporophyte (2n): Diploid, multicellular form of a plant. It forms haploid spores through meiosis.
Gametophyte (n): Haploid, multicellular form of a plant. It forms gametes through mitosis.
1. ANS: A sporophyte (It is in diploid, but its spores are haploid).
2. ANS: A gametophyte
3. ANS: A sporophyte
4. ANS: A gametophyte
5. ANS: A gametangium
6. ANS: An archegonium
7. ANS: antheridium
8. ANS: antheridium
9. ANS: gametophyte
10. ANS: Egg (After fertilization it divides and forms embryo).
11. ANS: A sporophyte (in spores it occur)
12. ANS: A sporangium (spores are produced when sporangium splits).
13. ANS: Spores (Spores are covered by a polymer called sporopollenin).
14. ANS: Spore (Through mitosis spores can produce gametes)..
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.
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.
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 . . .
