The stomata
Guard cells are specialized cells located around the stomata, or pores, on plant leaves. Their main function is to regulate gas exchange by controlling the opening and closing of these stomata. When guard cells absorb water, they swell and bend, causing the stomata to open, allowing carbon dioxide in for photosynthesis and oxygen out. Conversely, when they lose water, the stomata close to prevent water loss, helping the plant maintain its water balance.
slow cell growth
sugar solution does effect the opening and closing of stomata. when stomata is treated with sucrose solution, the guard cells will loss its water content as sucrose solution is more concentrated. water will moves from higher water potential (low concentrated) to low water potential (high concentrated). thus, water moves out from guard cell to its surrounding cell. when cell loss the water, it later lost its turgidity and shrink. the shrink cell eventually become flatten and close the stomata pore. . =)
Stomata are small pores found on the surface of leaves that regulate gas exchange in plants. They let in carbon dioxide for photosynthesis and release oxygen as a byproduct. They also allow water vapor to escape through transpiration.
Stomata
Usually, the stomata is the hole in the middle of a guard/s cell, underneath a leaf of a plant.
The stomata
No, stomata cells are not animal cells. Stomata cells are specialized plant cells responsible for gas exchange, whereas animal cells are the building blocks of animal tissues and perform various functions in animal organisms.
Carbon dioxide enters plant cells through small openings on the surface of leaves called stomata. The stomata open to allow carbon dioxide to diffuse into the plant cell during photosynthesis, where it is used to produce glucose and oxygen.
its not a cell
Stomata close under strong sunlight to prevent excessive water loss through transpiration and to protect the plant from drying out. Closing the stomata reduces the amount of water vapor that can escape from the leaf surface, helping the plant conserve water.
A plant cell has a cell wall.
A plant cell has a cell wall.
The gaurd cell in the stomata contain chloroplsts and uneven cell wall to create a pore on being turgid.
Neither Stomata nor mitochondria are cells, stomata are found in plants as a leaf's pores and mitochondria are cell organelles that serve as the powerhouse of cells by providing energy. Anyway, yes stomata are only found in plants b/c they're a specific kind of pore, and mitochondria are one of many organelles found in plant and animal cells.
The stomata, which are small openings on the surface of plant leaves, are responsible for allowing oxygen to move out of the plant and into the environment through a process called transpiration.
