is called
photosynthesis.

* A plant is full of vascular cells that transport water and
sap throughout, from root to leaf tip. As the amount of
sunlight decreases in autumn, the veins that transport sap
into and out of a leaf slowly close off. Then a layer of
cells, called the separation or abscission layer, develops at
the base of the leaf’s stem. When this layer is completely
formed, the leaf falls off.

* Before they can grow into new
plants, seeds need to leave the
seed pod. If all the seeds a plant
produced landed just underneath
the parent plant, they would be too
crowded, and the established large
plant might not leave them enough
light or water for them all to
develop properly.

Why do plants make food?
Plants make food the same reason humans make food to survive
without the essentials they wouldn’t be able to make food – The
things that plants cannot live without are water, carbon dioxide
from the air, sunlight, and nutrients in the ground! Plants use
these things in a special process called “photosynthesis” which
allows them to make their own food,

*Pollination is
when pollen is
transferred from
the anther to the
stigma of a plant
*What does the word
pollination mean?

* Photosynthesis is the process of converting light energy to
chemical energy and storing it in the bonds of sugar. This
process occurs in plants and some algae (Kingdom Protista).
Plants need only light energy, CO2, and H2O to make sugar.
The process of photosynthesis takes place in the chloroplasts,
specifically using chlorophyll, the green pigment involved in
photosynthesis.
