What is reproduction in plants   ?

Reproduction is one of the characteristics of living things that enable them to replicate , reproduce or in case of plants sprout forth young seedlings that resemble their parents . Plants do not move from one place to another because they are fixed in one position by their roots , hence they need the assistance of external factors to aim them in the process of reproduction . These external factors are called agents of pollination .


Methods of Reproduction in Plants 

There are two methods of reproduction in plants which are Sexual Reproduction and Asexual Reproduction

Sexual Reproduction in Plants : This involves the union of male and female gametes in plants to form seedlings .In sexual reproduction, flowering plants make use of seeds.  In most plants, the seedlings are developed from their flowers or fruits . These seeds, which are obtained from flower when the male and female parts of flower meet to form union, seeds are obtained from flower.


Asexual Reproduction : This type of reproduction in plants involve the reproduction of young seedlings or plants from parts of the parent plants . This type of reproduction in plants is also known as vegetative reproduction . This types of reproduction does not involve the union of the male and the female sex gametes . The types of vegetative propagation involves budding, spore formation , fragmentation and vegetative propagation . The use of vegetative parts of plants may involve the use of the plant’s leaves, stems, buds and roots for asexual or vegetative propagation . Some plants part can also reproduce young ones without seeds, plants like cassava  can reproduces by planting of the stem and  yam can reproduces by planting the  tuber.



Flower is the organ responsible for producing fruits in flowering plants. So, the male and the female reproductive parts of a plant are in the flower.

The two (2) major parts of flower are:

The Stamen or the Male part: it consists of the anther and filament.

The pistil or the female part: it consists of the ovary, stigma and style.


Part of a flower Function
Anthers It produces pollen grains
Stigma Receives pollen grains during pollination
Sepals Protects the floral parts in the bud
Petals Attracts insect because of the possession of sweet smell and bright colors.
Style It is the pollen tubes that carries the male gamete into the female gamete (ovary)
Ovary It houses the egg or the ovule
Filament It holds the anther

What is Pollination ? 

Pollination is one of the ways by which plants reproduce which involves the transfer of pollen grains from the anther to the stigma of flowers .

Types of Pollination 

  1. Self Pollination : This involves the transfer of pollen grains from the anther to the the stigma of the same flower
  2. Cross Pollination : This  involves the transfer of  pollen grains from the anther of one flower to the stigma of another flower

What are the agents of Pollination 

The agents of pollinations are those factors that help in the disperse of pollen grains from the anther to the stigma of flowers . These are the agents of pollination

  1. Human Activities on the farm
  2. Interaction of insects like butterfly or bee with flowers .
  3. Wind
  4. Water




The topic is presented step by step


Step 1:

The class teacher revises the previous topics


Step 2.

He introduces the new topic


Step 3:

The class teacher allows the pupils to give their own examples and he corrects them when the needs arise




The class teacher wraps up or conclude the lesson by giving out short note to summarize the topic that he or she has just taught.

The class teacher also goes round to make sure that the notes are well copied or well written by the pupils.

He or she does the necessary corrections when and where  the needs arise.


Evaluation . 

  • Define reproduction in plants
  • Explain Sexual reproduction
  • Mention Parts of a flower
  • Explain Pollination of flower
