Ecosystem processes Flashcards
producer
organisms that make their own food
consumer
organisms that get energy from eating other organisms.
word equation for photosynthesis
carbon dioxide + water = glucose + oxygen
word equation for aerobic respiration
oxygen + glucose = water + Carbondioxide
the stuff that makes leaves green
chlorophyll
the source of energy for plants
the sun
the reason why leaves have such large surface area is…
to absorb as much light as possible
cuticle
protects plants against drought, extreme temperatures, UV radiation, chemical attack and more
upper epidermis
mainly involved in water conservation by eliminating excess sunlight.
lower epidermis
mainly involved in gas exchange
palisade mesophyll
where most of the photosynthesis occurs in the leaf.
spongy mesophyll
facilitate the exchange of gases essential to the process of photosynthesis
guard cells
regulate CO2 influx from the atmosphere into the leaves for photosynthic fixation
Stoma(ta)
the hole on the bottom of the leaf for carbon dioxide to diffuse in and oxygen to diffuse out.
the place that plants store their excess glucose
starch
the place that humans store their excess glucose
fat, glucogen
