PLANT REPRODUCTION

Last day we were talking about PLANT NUTRITION. We are going to review today using one of our THINKING ROUTINES: QUICK WRITE / QUICK DRAW. Remember to draw and write as faster as you can with the ideas you had about last day lesson.

Today we are going to learn a bit more about how do plants reproduce. This STOPMOTION video will help you to understand.

• At the end of the video you have to answer these following questions.
  • What is it needed for POLLINATION?
  • Do you think that just the bees can help with transportation?

SEXUAL REPRODUCTION

• Flowers are the reproductive organs of the plant.
  • The stamens are the male. They produce polen.
  • The ovary is the female part. It produces ovules which becomes seeds.

POLLINATION

• Tiny pollen grains form on the stamens.
• POLLINATION is teh movement of pollen from stamens to ovary.
• It used to take place in the same plant.
• Wind and insects also carry plant to other plants.

SEEDS AND FRUITS

• After pollination the flower changes.
• Petals fall and ovary grows. It becomes a fruit with seeds.
• The fruit is ripe, it falls to the ground and the seeds fall out.
• The seeds germinate: they open, and small roots and tiny leaves grow.

ASEXUAL REPRODUCTION

• Some plants reproduce without flowers or seeds:
  • TUBERS: they are underground stems. It develops roots and a stem rise above the ground. For example he potato.
  • BULBS: they also grow underground. For example onions
  • STOLONS: These are stems which extend acroos the ground. Roots grop an a new plant begins. For example strawberries.

LET'S PRACTISE ALL WHAT YOU HAVE LEARN DURING THIS TOPIC WITH THE FOLLOWING ACTIVITIES.
