a flowering plant that produces seeds with TWO seed leaves or food storing veins. A bean seed.
a flowering plant that produces ONE leaf seed. About one third of plants are monocot. A corn seed.
a tough protective covering on the seed enclosing the enbryo and the food supply. When leaves on the young plant starts to grow and open up the seed coat falls off.
an organism in its earliest stages of development in most plants the embryo is found inside a seed and develops into a young plant
are the largest parts of the seed that supply food for the young plant while it's growing
material contained inside the seed
the sprouting of a seed to become a new plant when it begins to grow
the scattering of seeds aways from the parent plant
makes their own food through photosynthesis such as green plants and grass and trees and flowers
eats a producer-a living thing like humans, cows, cats or dogs
a bacteria or fungus that eats dead material and returns to the soil
5 STEPS OF GERMINATION
1. as soon a seed receives water and warmth the embryo starts to grow.
2. The root pushes its way out of the seed coat and begins to anchor to the soil so the seed can suck up water and minerals.
3. the stem begins to develop and grows upward searching for light
4. stems continue to grow and leaves form
5. germination is complete and the plant makes its own food through the leaves and can do photosynthesis
3 MAIN WAYS SEEDS ARE DISPERSED
1. WIND-the seeds fly in the air such as seeds from a dandelion or maple seeds that look like helicopters fall off maples trees
2. WATER-the seeds float from one ocean to another or by rain. The coconut seed floats and travels.
3. ANIMALS-they are carried in insect and birds mouths and chipmunks carry seeds and bury them. They can also be carried on the fur of animals.
What is a food chain?
A food chain is a series of steps showing the transfer of energy among living things.
AN EXAMPLE OF A FOOD CHAIN
1. The catepillar feeds on its leaves.
2. The robin preys on a caterpillar.
3. The hawk preys on the robin.
4. The earthworm feeds on the dead hawk and the nutrients passon to the soil later on.
2 examples of PRODUCERS, CONSUMERS, and DECOMPOSERS
1. PRODUCERS-grass and trees
2. CONSUMERS-human or cow
3. DECOMPOSERS-fungus or bacteria
What are the 2 main fuctions of a seed?
1. It contains stored food that helps young plants grow.
2. It contains stored food that helps the germination process.
