Throughout evolution, plants have continuously adapted to survive in changing environments. Apart from complex structural ...

Plant behavior may seem rather boring compared with the frenetic excesses of animals. Yet the lives of our vegetable friends, ...

How do plants breathe through stomata? Key regulators of stomata are plant vacuoles, fluid-filled organelles bound by a single membrane called the tonoplast. Plant vacuoles are fluid-filled ...

A multidisciplinary team led by researchers at the Yale School of the Environment developed a new laser-based method for observing how plants adjust the pressure within their cells in response to the ...

Plant behaviour may seem rather boring compared with the frenetic excesses of animals. Yet the lives of our vegetable friends, who tirelessly feed the ...

Each hole is a single stoma. Guard cells Controls the opening and closing of stomata. Midrib Provides strength throughout the leaf, keeping it upright and sturdy in the wind. Petiole Attaches the ...

When a plant senses light, a signal is sent to the guard cell to increase its ion content, which causes the cell to take in water and swell in size. In this state, the stoma is open so that it can ...

It moves by diffusion through small holes in the underside of the leaf called stomata. Guard cells control the size of the stomata so that the leaf does not lose too much water in hot, windy or ...

Gas exchange between the plant and the atmosphere takes place through the stomata, which consist in two bean-shaped guard cells surrounding a pore. (a) Malate and Cl − efflux from the guard ...

Stomata, microscopic pores on plant leaves, regulate gas exchange and water loss by opening or closing in response to environmental cues. Guard cells surrounding each stoma regulate this process ...
