Reproduction in Non Vascular Plants

• Algae – reproduce either sexually(2 parents using sperm and egg) or asexually(1 parent makes a copy of itself)

• Mosses and Liverworts- must do both sexual and asexual reproduction to make a baby

Pollination (Thanks, Cupid!)Pollination (Thanks, Cupid!)

Pollen is carried from the anther of one flower to the stigma of

another flower.

Pollen grains burrow down the pistil, style

From Flower to Fruit- a Love Story

From Flower to Fruit- a Love Story

Once upon a time, Rholl grew tomato plants in his garden.

In June, he began to notice little yellow flowers. He was very happy!

By the end of June, he was sad because the little yellow flowers

were gone.

By the end of July, he noticed small green bumps where the

flowers used to be.

The bumps got bigger and

bigger and bigger!

One day in August, he noticed the bumps turning yellow.

Finally one day at the end of August, he realized...These are

TOMATOES!!

These are flowers! They are the ripened ovaries of the tomato

flower.

Rholl presents his wife with a cart of partially rotten ovaries of a flower. I married

a geek!

“ That evening at dinner...”“ That evening at dinner...”

Science geek Rholl proves his point by dissecting the salad to reveal seeds in the tomatoes

Afruit is a ripened ovary!

Mrs. Rholl admitted that even though she married a science geek, she married the smartest man in the whole wide world!

See, it is a See, it is a love story.love story.
