What part of the leaf stops the leaf cells from drying out?
waxy layer
What pigment makes leaves green?
chlorophyll
What ADAPTATION does this cell have to help it function?
large surface area
Why does chlorophyll appear to be green?
it reflects green light & absorbs other colors
What is the function of chlorophyll?
absorb light energy from sunlight
Besides transporting water and minerals, what is ONE OTHER FUNCTION of xylem vessels?
support plant (has strong, hard walls)
What gas is made by plants in photosynthesis?
oxygen
In a food chain/web, what do the arrows represent?
energy transfer / flow
Every food chain begins with a ___.
plant / producer
What is the name of the vessel that transports water and minerals in plants?
xylem
What does "synthesis" mean?
making
What is "biomass"?
material / substance that is made of living cells and tissues
Why do plants need photosynthesis?
to make food
What layer of the leaf contains cells that do most of the photosynthesis?
palisade layer
These tiny holes in a leaf allow gases to move in and out.
stomata
What two things do plants absorb from the soil?
water & minerals
Why are most leaves thin?
so light can reach all the cells inside them

bubbles (of oxygen)
What are the two REACTANTS for photosynthesis?
water and carbon dioxide
What is the function of this cell?
absorb water (part of roots)
