Plants have small pores on the underside of their leaves, known as stomata. When the sun rises, these pores open and the plants absorb carbon dioxide (CO 2) from the atmosphere, which they need, in ...

Scientists have discovered that certain plants can survive stressful, dry conditions by controlling water loss through their leaves without relying on their usual mechanism - tiny pores known as ...

New research in plants shows that a gene called MUTE is required for the formation of stomata -- the tiny pores that a critical for gas exchange, including releasing the oxygen gas that we breathe.

Plants constantly make trade-offs in their decisions: more light means more opportunity for photosynthesis, but then hot temperatures and dry air makes wilting more likely. Stomata - microscopic ...

All living organisms need energy to perform various life processes and so plants also. To perform various metabolic activities plants need food for energy. With the help of the process of ...

Plants need food to respire, grow and reproduce. Unlike animals, plants are able to make their own food by the process of photosynthesis. Photosynthesis takes place in the part of the plant cell ...

A leaf usually has a large surface area, so that it can absorb a lot of light. Its top surface is protected from water loss, disease and weather damage by a waxy layer. The upper part of the leaf is ...

Plants know how to do a neat trick. Through photosynthesis, they use sunlight and carbon dioxide to make food, belching out the oxygen that we breathe as a byproduct. This evolutionary innovation is ...
