Photosynthesis Flashcards
Air Space
allows quicker diffusion of gas
Algae
simple aquatic organisms that make their own food through photosynthesis and are similar to plant cells
Compensation Point
point at which respiration and photosynthesis are equal
Epidermis
the outer layer of tissue in a plant
Guard Cells
either side of the stomata, able to close those up to reduce gas transfer and water loss
Inverse Square Law
light intensity is equal to one over distance squared
Photosynthetic Cell
cell packed full of chloroplasts to perform photosynthesis
Potometer
apparatus for measuring the amount of water a plant loses through transpiration
Spongy Mesophyll
middle of the leaf, a bit like a sponge, it soaks up water and nutrients and passes it along to other cells
Stomata
holes which allow gas transfer to let water out
Synthesis
the creation of something
Turgor
the pressure inside a plant cell
Wax Cuticle
a protective layer of the leaf
Wilting
protection against water loss in plants
