Why do we choose a leaf that has been exposed to light for some time?

i belive that the leave was covered so that lis=ght could not pass through them as we are testing whether light is needed for starch reproduction

Where in the leaf does almost all photosynthesis occur?
Almost all photosynthesis occurs in the chloroplasts, specifically in the chlorophyll molecules located in the mesophyll cells of the leaf. The mesophyll cells are located in the middle layer of the leaf, where they are well exposed to light.
What substance is produced when a green leaf is exposed to sunlight?
i think it is oxygen
What does sun supply to a leaf?
The sun can supply light and heat to the leaf.
Will photosynthesis take place in foil covered leaf?
no because the leaves or anyother part of the plan has to be exposed to the sun so the energy from the light will hit the plant and it can crreate sugar to supply energy (with carbon dioxide as well)
What does the sun supply to the leaf?
Light energy.

What is the function of the leaf in plant?
The function of a plant leaf is to provide a structure in which chloroplasts can be exposed to sunlight so that they can perform photosynthesis.
When light energy from the Sun strikes a leaf how is the energy conserved?
When light energy strikes a leaf then chlorophill (a) present in leaf absorb that light energy . By use of that energy photosynthesis occurs.
What happens when light strikes a green leaf?
the leaf reflects on the light so it prevents it to burn (fire)
What are 3 analagies to a leaf?
1. Your as green as a leaf 2. Your as light as a leaf. 3. He fell down as slowly as a leaf
When light strikes a green leaf how does this explain why leaves appear green?
Light that is white contains all the colours. When the light hits the leaf, it absorbs all the colours apart from the green light which is reflected back out to your eyes. So you see the leaf as green.
When white light shines on a green leaf why do you see green?
our eyes detect the green light that is reflected off the leaf
Does the size of a leaf affect the rate of transpiration?
The more leaves the plant has, the more surface there is for photosynthesis. This means there will be more stomata so the plant can take in more carbon dioxide. This will also result in more water vapour leaving the plant.
How do you play a gum leaf?
Take one large gum leaf. With your fingernail, scratch off a small piece of the flesh of the leaf from one side, leaving the membrane of the other side exposed. It is slightly transparent if done successfully. With your lips pursed, blow across the exposed membrane to make a sound. Accomplished gum leaf players can get simple tunes out of the vibrating edge of the membrane.
