Examining the Structure and function of parts of seed plants

seed coat

the outer covering of a seed

Germination

The process of a seed beginning to grow

Moisture and warmth

things a seed needs to grow

what happens when a bean seed is soaked in water?

The seed swells and the seed coat becomes soft and splits

vascular plants

plants with root, stems, and leaves

vascular plants need

water, light and carbon dioxide , and mineral nutrients to live

angiosperms

flowering plants, seeds in fruits

examples grass, corn, bean, sunflower, strawberry, tomato

gymnosperms

seeds in cones

example cedar, pine and spruce trees

roots

hold plant in the soil; absorb water and mineral nutrients.

stem

supports he part above the ground; carries water and minerals to leaves from roots

leaves

make the plant's food

embryo

is the first stage of life of a bean plant

cotyledons

the 2 halves of the embryo.

provide food for the new plant until the plant has green leaves and can make its own food.

The radicle

is the beginning of the root system of a plant.

how do you know the tree was an angiosperm?

flowers and fruit

photosynthesis

process by which plants make their own food

Stomata

tiny holes locates on the UNDERSIDE OF LEAVES

chlorophyll molecules

make leaves look green

molecules where sunlight is absorbed in the leaves of plants

Glucose

Glucose is the plant's food.

sugary substance produced by a chemical reaction in leaves

FORMULA FOR PHOTOSYNTHESIS

WATER+CARBON Dioxide+LIGHT--GLUCOSE+OXYGEN

6H2O+ 6CO2---C6H1206+6O2
