Asexual Reproduction Genetically Identical
Offspring

• Budding
• Binary Fission

Budding

• New Organisms Arise as an Outgrowth from the
  Parent Organism
• Seen Mostly in Marine Animals
• Examples Include Hydra.

Hydra with bud

Imagine

• Apart from budding and binary fission, there are
  other methods by which a single parent reproduces
  the young ones. You will study about these in
  your higher classes.

Activity

• Get Permanent slides of hydra, observe them using
  hand lens or a microscope. Look out for any
  bulges from the parent body. Count the number of
  bulges that you see in different slides. Also,
  note the size of the bulges. Draw the diagram of
  hydra, as you see it.
