how plants harness energy from the sun to make food, happens in the chloroplasts.endothermic
plant structure
waxy cuticle
upper epidermis
palisade mesophyll
spongy mesophyll
lower epidermis
guard cells
stomata
waxy cuticle
leaf adaptations for photosynthesis
shape gives them a large surface area for more light
veins conrains the xylem (water) and phloem (glucose)
thin layer allows gases to diffuse easily
photosynthesis affecting factors
light intensity
carbon dioxide concentration
temperature
amount of chlorophyll
light intensity
directly proportional to photosynthesis
limiting factor
at some point, the graph plateaus, meaning there is something else limiting the rate of photosynthesis and it is no longer light intensity
carbon dioxide concentration
a reactant in photosynthesis
directly proportion to photosynthesis
limiting factor
at some point, the graph plateaus, meaning there is something else limiting the rate of photosynthesis and it is no longer carbon dioxide concentration
temperature
directly proportional to photosynthesis
increases until it reaches the optimum temperature
at this point, the enzymes become denatured
amount of chlorophyll
reduced amount = less photosynthesis
happens when a plant is deficient in magnesium ions
how plants use glucose
F ats - glucose used to produce these for storage in the plant
O ils these for storage in the plant
S tarch - glucose is converted and another storage material
R espiration - glucose broken down to release energy
A mino acids - glucose used to produce. they are used in protien synth
C ellulose - glucose used to produce it, strengthens the cell wall
