Plants Growing
Plants are alive, just like people and animals. How do we
know this? Living things all do certain things:
·
They grow and die.
·
They need energy, nutrients, air, and water.
·
They produce young.
·
They are made up of cells.
·
They react to what's around them.
Starting
to Grow
Where Do Plants
Come From?
Plants come from seeds. Each seed contains a
tiny plant waiting for the right conditions to germinate, or start to grow.
What Do Seeds Need to Start to Grow?
Seeds wait
to germinate until three needs are met: water, correct temperature (warmth),
and a good location (such as in soil).
During its
early stages of growth, the seedling relies upon the food supplies stored with
it in the seed until it is large enough for its own leaves to begin making food
through photosynthesis.
The
seedling's roots push down into the soil to anchor the new plant and to absorb
water and minerals from the soil. And its stem with new leaves pushes up toward
the light.
The germination stage ends
when a shoot emerges from the soil. But the plant is not done growing. It's
just started. Plants need water, warmth, nutrients from the soil, and light to
continue to grow.
