Life Cycle and Structures of a Plant
germination
Process in which seed coat splits open and a root begins to grow downward into the soil.
sprout/seedling
A tiny shoot begins to grow upward from the germinated seed.
plant growth
Period of time when the plant gets taller, grows
more leaves, and makes its own food by photosynthesis.
more leaves, and makes its own food by photosynthesis.
flower buds
Appear at the end of stems.
flowers
Responsible for creating new seeds if pollinated.
pollination
Process in which a pollinator (bird, insect or wind) moves pollen from one flower to another, fertilizing the flower so new seeds can grow.
Fruit or seed pod formation
Forms around the seeds to protect them until they are ready to be planted.
Seed dispersal
The fruit or seed pod opens and seeds are scattered (by wind, water, or animals) to land on/in the ground and begin germinating.
Hooks and burrs
Small hooks on seeds that attach themselves to animals so seeds can get scattered.
root
anchors the plant, brings water and minerals to plant from soil
stem
holds plant up and transports water and food through plant
leaf
"food factory" for plant, using sunlight, water and carbon dioxide to create food (sugar) for the plant, and oxygen.
chlorophyll
green substance in leaves and stems, needed for photosynthesis to occur
flower
contains eggs that can be fertilized to make new seeds
pistil
receives pollen and grows a tube to the ovary to fertilize the eggs
stamen
produces pollen, a yellow powder
pollinator
helps moves pollen from one flower to another, like a bee, bird, butterfly or other insect.
sepal
like small green leaves, helps protect flower before it opens
receptacle
end of flower stalk
petals
bright part of flowers that help attract the attention of pollinators like bees.
