Photosynthesis Flashcards
What do chloroplasts contain
Photosynthetic pigments, chlorophyll a, chlorophyll b, carotene, they are found in thylakoids membrane las and are attached to proteins
Pigment and protein=photosystem
what is the distance like in leaf and so what
no living cell is far away from the external environment so receive a good supply of co2 and o2
what leave have and so what
large surface area so maximum absorption of snlight
what is leaf covered by and so what
covered by a transparent cuticle which allows light to penetrate
what does stomata allow
the rapid exchange of gases
what does xylem and phloem provide
xylem inputs water and phloem re,oves ending products
what does stacking do
the thylakoid stacking maximises absorption of sunlight and allows a lot of pigment to be stored
what does the stroma contain
all the enzymes needed for photosynthesis
what is also included in the stroma and why
contain ribososmes and dna needed for protein synthesis
what does peremeable membrane allow
diffusion of gases
what does membrane provide
Attachmenrt of protiens like electron carrier
