Lots of chloroplast Contain a green substance called chlorophyll, which traps energy from the sun for photosynthesis. Stomata Tiny holes found mainly underneath the leaf to allow gases to diffuse ...

First, students learn how stomata density affects leaf carbon, water, heat budgets, and photosynthesis. Then, students design their own study to compare stomata density among leaves that differ in ...

These arms and pads contain the stomata and chloroplasts responsible for photosynthesis. The arms of this cactus allow it to photosynthesize in the absence of leaves. Credit: Engin Akyurt/Unsplash ...

This is the basis for the opening and closing of a stoma, known as stomatal movement, which controls gas exchange necessary for photosynthesis and limits water loss. How do guard cells change ...

Indeed, chloroplasts resemble modern cyanobacteria, which remain similar to the cyanobacteria of 3 million years ago. However, the evolution of photosynthesis goes back even further, to the ...
