Plants and fungi reproduce through both asexual and sexual reproduction. Flowering plants reproduce sexually, with pollen carrying genetic information from male to female parts during pollination to fertilize ovules into seeds. Non-flowering plants like ferns and mosses lack flowers and seeds and instead reproduce using spores. Fungi also reproduce via spores rather than seeds.

3. 1.-WHAT IS REPRODUCTION?
Reproduction is the capacity of all living systems to
give rise to new systems similar to themselves. The
term reproduction may refer to this power of self-
duplication of a single cell or a multicellular animal or
plant.
The reproductive process always includes the
transmission of hereditary material from the parents
to the offspring.

4. 3.-ASEXUAL REPRODUCTION
Asexual reproduction only
needs one parent, unlike
sexual reproduction, which
needs two parents. Since
there is only one
parent, there is no fusion of
gametes and no mixing of
genetic information. As a
result, the offspring are
genetically identical to the
parent and to each other.
They are clones.

5. 2.-SEXUAL REPRODUCTION
Sexual reproduction happens
when a male gamete and a female
gamete join. This fusion of
gametes is called fertilisation.
Sexual reproduction allows some
of the genetic information from
each parent to mix, producing
offspring that resemble their
parents, but are not identical to
them. In this way, sexual
reproduction leads to variety in
the offspring. Animals and plants
can reproduce using sexual
reproduction.

6. 4.- PLANTS REPRODUCTION
4.1.- Flowering Plants.
Flowering plants produce seeds inside the base of the
flower, the ovary. Flowering plants make up over 80
per cent of all plant species. The flowering plants
reproduce sexually.

8. The petals are often colourful. They attract insects to
the flowers.
The stamens are the males sexual organs. They consist
of the anther and the filament. The anther contains
the pollen.
The pistils is the female sexual organ. The parts of
the pistil are the stigma, the style and the ovary. The
ovary contains the ovules.
The sepals are small and usually green. They protect
the flower when it is a bud.

9. 4.1.2.-Flowering plants or angiosperm.
Known as angiosperms (which means “seed
cases”), flowering plants produce seeds inside the
swollen base of the FLOWER, the ovary.
The flowers contains the plant’s reproductive organs.
They are the showy parts of flowering plants. Many
depend on animal pollinators, which they attract with
their colour or scent.

10. 4.1.3.-Pollination.
Pollination is the process meanwhile the stigma
catch the pollen. The pollen can be carry by insects
birds or by the wind. The pollen caught by the
stigma is transported to the ovary through the
style, there the pollen fertilise the ovules and
finally the ovules develop into a seed.

11. 5.- Non-seed plants
Ferns usually have underground stem and long
divided leaves. They don’t have seeds. They have
spores
Mosses have very short stems and small leaves.
They don’t have roots. They don’t have seeds. They
have spores.

12. 5.- Fungi are not either animals or
plants, though they are more closely
related to animals than they are to plants.
Like ferns or mosses they reproduce by
spores.
A spore is a single-celled reproductive
body that can grow into a new organism.
