photosynthesis. Flashcards
what are the factors that affect photosynthesis?
light intensity.
temperature.
carbon dioxide concentration.
why does light intensity affect photosynthesis?
limited by light intensity.
limited by carbon dioxide concentration or temp.
why does temperature affect photosynthesis?
particles have more energy - increase rate.
optimum temp then they become denatured.
why does carbon dioxide concentration affect photosynthesis?
limited by carbon dioxide concentration.
limited by light intensity or temp.
how does a plant use the product of glucose it has produced?
used by plant for respiration.
may also be changed into other products: insoluble starch ( stored in stem, leaves, or roots.)
fat or oil which is also stored eg: in seeds.
cellulose- to strengthen cell walls.
proteins- growth and for enzymes.
what do you test a green leaf for and what does this let you know?
starch.
plant has photosynthesising.
what does the graph for rate of photosynthesis and light intensity looks like?
curved line going up. like the start of n.
what is the graph for rate of photosynthesis and light intensity limited by at the beginning and end?
end: co₂ concentration or temp.
what does the graph for rate of photosynthesis and co₂ concentration?
curved line going up like the start of n.
what is the graph of rate of photosynthesis and co₂ concentration limited by at the beginning and end?
end: light intensity or temp.
beginning: co₂ concentration.
what is the graph for rate of photosynthesis and temp look like?
n.
what is the graph rate of photosynthesis and temperature limited by at the beginning, middle and end?
beginning: particles have more energy- increases rate of reaction.
middle: optimum temp.
end: enzymes denatured.

function of tissue and how it has adapted to its function: spongy mesophyll.
gas exchange.
big air spaces.
function of tissue and how it has adapted to its function: palisade mesophyll.
photosynthesis.
contains lots of chloroplasts.
function of tissue and how it has adapted to its function: epidermal.
reduce water loss.
covers whole plant.
function of tissue and how it has adapted to its function: meristem.
allows plant to grow.
differentiate into different types of plant cell.
function of tissue and how it has adapted to its function: xylem.
transport water and minerals.
vascular bundle.
function of tissue and how it has adapted to its function: phloem.
transport food.
vascular bundle.
