Plant life cycle

Male and female parts • Color the anther blue and the pistil pink

Pollination

• Pollen is made in the anther• Eggs or ovules are made in the Pistil• Pollen leave the anther by wind,

water and animals

Pollination: Flowers do not

have to be beautiful

• Krubi

Pollination: Flowers do not have to be beautiful

• Rafflesia

FERTILIZATION• Pollen will stick to the sticky tip of

the stigma

Fertilization • Sperm inside the pollen will swim

down the HILUM• Which is a tube that connects the

pistil to the OVARY• Label the sperm and egg.• The sperm carries ½ of the

chromosomes, and the egg carries ½ of the chromosomes

FERTILIZATION• The EMBRYO (baby) forms inside the

ovule after fertilization• The plant feeds the embryo through

the hilum• The embryo and other parts of the

seed grow by the process of…. Guess….

• Mitosis• The ovule will grow until it matures

and forms a seed

GERMINATION

• LABEL• Hilum,

embryo, seed coat, cotyledon

Germination

• Functions • Hilum: attaches seed to plant for

food/water• Embryo: baby plant• Cotyledon: stored food for

germination• Seed coat: protection

Germination • Germination is when the embryo

leaves the seed• It pushes out the root, and grows

root hairs

In a human….

In a human….• What would do the same job as the cotyledon?

• Where is the embryo?• What would do the

same job as the seed coat?

• Compare how the plant embryo and human embryo get energy and nutrients to do mitosis

Germination

• Root hairs soak up water by the process of ….. Guess….

• Diffusion• Then the leaves pop out, and start

growing• The plant can then start to perform

photosynthesis
