Content :

What are insects and wind pollinated flowers   ?

Insect pollinated flowers are quite different from wind pollinated flowers in the following ways

  1. Insect pollinated flowers produce nectars to attracts insect while wind pollinated flowers do not
  2. Insect pollinated flowers produce scents while wind pollinated flowers do not .
  3.  Insect pollinated flowers are not light weight while wind pollinated flowers are light weight
  4. Insect pollinated flowers produce large petals that are brightly coloured to attract insects while wind pollinated flowers do not
  5. The pollinating agent for insect pollinated flowers are insects while the pollinating agent for wind pollinated flower is wind

 

FERTILIZATION AND FRUIT DEVELOPMENT IN PLANT

Fertilization in plant occurs after pollination, the male sex cell or sperm (male gamete) in the pollen grain unite with the female sex cell, or ovule in the ovary to form seeds (zygote and embryo), which  develop  to form the fruit.

Differences between pollination and fertilization

Pollination Fertilization
It is the transfer of male part into the female part. It is the union of the male gamete and female gamete.
It occurs outside the plant It occurs inside the plant
Agents are needed for pollination to occur Fertilization occur without  any agent

 

 

 

Presentation

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

 

 

Conclusion

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 . 

  • Mention two differences between wind pollinated flowers and insect pollinated flowers
  • Mention two differences between fertilization and pollination
  • Mention Parts of a flower
  • Explain Pollination of flower

Assignment

Prepare for the next lesson by reading about water cycle
