Study Notes

Photosynthesis Location

Photosynthesis occurs in chloroplasts, organelles inside plant cells.
Chloroplasts contain large amounts of chlorophyll, a green pigment used to capture light energy.
Chloroplasts are surrounded by two membranes: an outer and inner membrane.
Inside chloroplasts, thylakoids are small membrane disks.
A stack of thylakoids is called a granum.
The stroma is the fluid-filled space inside the chloroplast.
Leaves contain chloroplasts and microscopic pores called stomata located on the underside of the leaf.
Stomata allow carbon dioxide to enter and oxygen to exit the leaf during photosynthesis.
Guard cells regulate the opening and closing of stomata, controlling gas exchange.
Chlorophyll absorbs light energy, other colours are reflected, making the leaves appear green.
The absorbed light energy powers photosynthesis.
