what is reproduction?
Reproduction is a fundamental
feature of all known life; each
individual organism exists as the
result of reproduction.

Plant reproduction is the
process of generating new plant
individuals or offspring.
8. STEM:
Provides support for the leaves, flowers and fruit.
SEPALS:
Protects the developing reproductive structure.
PETALS:
Can be colorful to attract specific pollinator to the flower.
STAMEN:
Male reproductive part. Contains 2 parts which is the Anther and Filament.
ANTHER:
Produces male sex cells or pollen grains.
9. FILAMENT:
Holds the anther
CARPEL/PISTIL:
Is the female reproductive part. Contains 3 parts which is Stigma, Style and Ovary.
STIGMA:
Collects pollen grains.
STYLE:
Supports the stigma and connects it to the ovary. It also assist the process of
fertilization.
OVARY:
Protects the ovule.
OVULE:
Female gamete or egg cells.
10. Flower

Flower
The organ of sexual reproduction is the flower.
Male gametes are found in pollen grains and
produced in the anthers of the flower. Female
gametes are found in ovules and produced in
the ovary of the flower.
11. TYPES OF
FLOWER
BISEXUAL FLOWER
Contains both male and female reproductive organs.
UNISEXUAL FLOWER
Has only one reproductive part. Each flower is either
"staminate" (having only functional stamens) and thus "male",
or "carpellate" or "pistillate" (having only functional carpels)
and thus "female".
12. Sexual Reproduction

Flowering plants reproduce sexually through a process
called pollination. The flowers contain male sex organs
called stamens and female sex organs called pistils. Plants
can either self-pollinate or cross-pollinate.
13. 2 TYPES OF POLLINATION
SELF POLLINATION
Self-pollination is a form of pollination in which
pollen from the same plant arrives at the stigma
of a flower or at the ovule.
CROSS POLLINATION
Cross-pollination is the process of applying pollen from
one flower to the pistils of another flower. Pollination
occurs in nature with the help of insects and wind.
14. SEED
SEED
Seeds produced through fertilization
contain genetic material from both
parents. As a result, the offspring are not
genetically identical to either of the
parent plants.
15. Asexual Reproduction
Asexual Reproduction
Asexual Reproduction

in Plants
Asexual reproduction produces plants that are
genetically identical to the parent plant because no
mixing of male and female gametes takes place.
Vegetative reproduction results in new plant individuals
without the production of seeds or spores
16. Reproduction in Animals

H O W D O A N I M A L S R E P R O D U C E ?
During sexual reproduction in animals, a haploid sperm and
unites with a haploid egg cell to form a diploid zygote. The
zygote divides mitotically and differentiates into an embryo. The
embryo grows and matures, After birth or hatching, the animal
develops into a mature adult capable of reproduction.
17. Human Reproduction
Human Reproduction
Human Reproduction
Human reproduction is any form of sexual
reproduction resulting in human fertilization. It
typically involves sexual intercourse between a
sexually mature male and female. These are
specialized reproductive cells called gametes,
created in a process called meiosis.

Some animals are also capable of asexual
reproduction whenever sexual reproduction is not
possible. Asexual reproduction in Animals occurs in
invertebrates and can be done through Budding or
Fragmentation.
19. BUDDING
BUDDING
where an outgrowth arises from a parent and drops
off to develop into a new organisms
hereditary material in the daughter cell and parent
are exactly the same
occurs in organisms such as Hydra, Jelly fish, Sea
anemones, Yeast and some Fungi.
20. FRAGMENTATION
FRAGMENTATION
Multicellular or Colonial organisms is a form of
Asexual reproduction or cloning in which an
organism is split into fragments. Each of these
fragments develop into mature, fully grown
individuals that are clones or the original organism.
21. PARTHENOGENESIS
PARTHENOGENESIS
Parthenogenesis is a form of asexual
reproduction by self-impregnation resulting
in the production of a zygote from an
unfertilized egg. Thus, it is also referred to by
many as “virgin birth”. Parthenogenesis takes
place in both asexual animals and plants. In
animals, the embryo develops from an
unfertilized egg.
22. Heredity, also called inheritance or biological
inheritance, is the passing of traits from parents
to their offspring; either through asexual
reproduction or sexual reproduction, the
offspring cells or organisms acquire the genetic
information of their parents.
Transfer of Genes from
Parent to Offspring

Assisted reproductive technology (ART) is used to treat
infertility. It includes fertility treatments that handle both a
woman's egg and a man's sperm. It works by removing eggs
from a woman's body. The eggs are then mixed with sperm
to make embryos. The embryos are then put back in the
woman's body. In vitro fertilization (IVF) is the most common
and effective type of ART.
24. Genetic Engineering
Genetic Engineering
Genetic Engineering
Genetic engineering is the process of using
recombinant DNA (rDNA) technology to alter the
genetic makeup of an organism. Genetic
engineering involves the direct manipulation of
one or more genes. Most often, a gene from
another species is added to an organism's
genome to give it a desired phenotype.
25. In Vitro Fertilization
In Vitro Fertilization
In Vitro Fertilization
In vitro fertilization (IVF) is a complex
series of procedures used to help with
fertility or prevent genetic problems and
assist with the conception of a child.
During IVF , mature eggs are collected
(retrieved) from ovaries and fertilized by
sperm in a lab.
26. Plant Tissue Culture
Plant Tissue Culture
Plant Tissue Culture
Plant tissue culture is defined as culturing plant
seeds, organs, explants, tissues, cells, or protoplasts
on a chemically defined synthetic nutrient media
under sterile and controlled conditions of light,
temperature, and humidity.
