All the stages of an organism’s life

Seed:

Each seed contains a plant embryo.

Each seed contains food for the embryo. The food helps the embryo survive during the

time it cannot make its own food. A tough outer case protects the embryo

Germinate:

Seeds do not always germinate right away; they can wait for extensive periods of time to grow.

When a seed germinates, it begins to grow.A seed needs water, nutrients and the right temperature to grow.

Seedling:

After the seed germinates, it grows into a young plant called a seedling.

It looks like its parent because of heredity.Color and size (height and weight) are examples of heredity.

Stages of the Life Cycle:

Seeds germinate into a plant. The plant grows, develops, reproduces and

then dies.

How Are Seeds Made?

Flowering Plants

sunflower, tulips, marigold,lily, jasmine, rose,lotus,hibiscus, Petunia,daisy,water lilies

Conifers

pine, fir, spruce,

evergreen

FLOWERING PLANTS

Female parts: Male parts:

-- makes the eggs that -- makes pollen, which is become seeds. the powdery material

that is needed by the

eggs to make seeds.

Eggs + Pollen = Seeds

FLOWERING PLANTS

Eggs + Pollen = Seeds

Wind

Insects (bees/birds)

Animals Nectar = sugary liquid in flowers.

While the animals drink the nectar, pollen rubs off on their bodies. When they move to other flowers, some of the pollen is transferred to female flower parts.

Life Cycle of a Flowering Plant

3.The plant is an adult.

1. A seed might become a new plant.

2.A new plant grows.

4.The plant flowers.

Insects, wind, or animals carry pollen to eggs.

5.Flowers become fruits with seeds.

Conifers

• Some plants do not have leaves; they have needles or brushes.

• There are two kinds of cones: ***small pollen cones ***large seed cones

Wind blows pollen from small to large cone. Pollen + large cone = Seed

Pollen + large Conifer Cone = Seed

• Seed grows inside a large cone.

• When seeds are ripe, they fall to the ground.

• Each seed has the ability to germinate and eventually grow into a tree.

Life Cycle of a Conifer

3.It makes two kinds of cones..

1. Ripe seeds from a large

cone germinate in the soil.

2.A new tree grows.

4.Pollen from the small cone falls on the larger cone.

5.This larger cone grows with seeds

Inside. Ripe seeds fall to the ground.

What Other Ways Do Plants Reproduce?

• Seeds

• Cuttings: pieces of the plant that was cut off from the original. When placed in water, new roots will grow. (i.e., perennials such as salvias, geraniums, asters and dianthus, as well as roses, heathers, hydrangeas and more)

What Other Ways Do Plants Reproduce?

• Bulb: an underground stem (i.e., onion)

• Tuber: an underground stem (i.e., potato)

What Other Ways Do Plants Reproduce?

• Spores: not as tough as seeds and does not have a food supply but if it gets light, water, and nutrients, it can grow into a new plant. (i.e., mosses and ferns)
