Content:

Plants’ Reproduction:

1. Meaning:
   • Reproduction is how plants make new plants.
   • Plants can make babies to grow into new plants.
2. Types of Reproduction:
   • Sexual Reproduction:
     • Plants make seeds by joining pollen (from male) with eggs (from female).
     • Example: Apple trees produce seeds through flowers.
   • Asexual Reproduction:
     • Plants make new plants without seeds.
     • No need for pollen and eggs.
3. Types of Asexual Reproduction:
   • 1. Cutting:
     • Pieces of a plant can grow into new plants.
     • Example: Rose stems can grow into new rose plants.
   • 2. Runners:
     • Plants send out shoots that become new plants.
     • Example: Strawberries make runners for new strawberry plants.
   • 3. Tubers:
     • Plants grow new plants from underground stems.
     • Example: Potatoes grow new plants from their “eyes.”
   • 4. Bulbs:
     • Plants make new plants from bulbs underground.
     • Example: Tulips grow from bulbs in the ground.
   • 5. Suckers:
     • New shoots grow from the plant’s base.
     • Example: Some fruit trees create new trees from suckers.

Remember, plants have cool ways to become new plants! 🌱
