REPRODUCTION

(ROCK!)

How can we define reproduction?

• Does it have to do with sex?

• Are there many types?

• Do all organisms reproduce?

• Can organisms reproduce in more than one way?

• What are flowers?

• How is an apple formed?

Reproduction is the production of new

organisms.

Types of reproduction

• Asexual reproduction: it is the biological process by which an organism creates an identical copy of itself. Only 1 parent or 1 cell is involved.

• Sexual reproduction: in this case two parents or two cells are needed. The new organism is different to its parents (even if it has some information from each of the parents).

SEXUAL OR ASEXUAL?

AND THESE?

ARE THESE ALIENS?

PLANTS ALSO HAVE ASEXUAL REPRODUCTION AS BULBS (onions), TUBERS (potatoes), RUNNERS (strawberries), . . .

IS IT THE ONLY TYPE OF REPRODUCTION THEY HAVE?

DO YOU THINK THIS LOBSTER AND THIS SHARK HAVE ASEXUAL REPRODUCTION? ONLY? AND THE KOMODO DRAGON?

TWO CELLS COMING FROM TWO DIFFERENT PARENTS. . .

Which kind of reproduction is this? Which is the name of these cells?

WHAT ARE THESE? DO THEY HAVE ANYTHING TO DO WITH REPRODUCTION?

WHICH TYPE?

FLOWERS CONTAIN THE PLANT’S SEXUAL ORGANS!!! IN THESE ORGANS WE FIND THE PLANT´S SEX CELLS: POLLEN AND EGG (OVULE).
