Photosynthesis Y8 Flashcards
(29 cards)
nitrogen in plants
makes proteins and causes growth
Phosphorus benefits for plants
energy transfer and helps with strong roots
potassium in plants
helps with drought tolerance, good fruit
magnesium in plants
component of chlorophyll
minerals come from…
rocks, soil, artificial fertiliser and manure
chromatography
separation of materials by passing it through a medium
signs of nitrogen deficiency in plants
lower leaves go yellow
signs of phosphorous deficiency in plants
poor flower growth, yellow leaves, dead spots
signs of magnesium deficiency in plants
top leaves go yellow
plants are…
producers
stomata
small openings on the bottom of a leaf, regulated gas exchange and controls water loss
palisade cell
found in the upper layer of leaves. Lots of chloroplasts for photosynthesis
spongy layer
loosely packed cells, some photosynthesis occurs here
lower epidermis
contains chloroplasts, guard cells and stomata
guard cells
control opening and closing of the stomata
palisade layer
where most photosynthesis takes place
symbol equation for photosynthesis
6CO2 + 6H2O -> C6H12O6 + 6O2
word equation for photosynthesis
Carbon dioxide + water -> glucose + oxygen
photosynthesis
Plants use the sun’s energy to convert water and carbon dioxide into sugars
glucose
A simple sugar that is an important source of energy
What do xylem tubes transport?
Water and minerals
What do phloem tubes transport?
Glucose
What is the vein of a leaf?
Tiny tubes that carry water into the leaf for photosynthesis and glucose out of the leaf for use in respiration within the plant
What is the waxy cuticle?
Waterproof layer which reduces water loss by evaporation
