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 Germination
