Guard cells diagram

Expert Answer: The opening and closing of stomata are controlled by the guard cells. When water flows into the guard cells, they swell up and the curved surface causes the stomata to open. When the guard cells lose water, they shrink and become flaccid and straight thus closing the stomata. The cell wall surrounding the pore is tough and flexible. The shape of guard cells usually differs in both monocots and dicots, though the mechanism continues to be the same. Guard cells are bean-shaped and contain chloroplasts. They contain chlorophyll and capture light energy. The subsidiary cells surround the guard cells. ei the following parts of the leaf in the diagram below.

A student set up an experiment to investigate water loss from leaves. The student: • took ... Thus, the guard cells swell. The walls of guard cells of stomatal pore are thicker outside and the walls present inside are thinner, guard cells bulge to due to the inflow of water, thus widening the stomatal opening. When the osmotic pressure of the guard cells becomes lower (during the night), the water leaves these cells due to exosmosis and ... Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata. Light is the main trigger for the opening or closing.

Answer (1 of 2): Leaves have special pores called stomata that make gas exchange possible while helping to control the loss of water. The stomata operate through the use of two tiny jellybean shaped cells called guard cells located in the outer layer of tissue called the epidermal layer. Guard ce... Essentially, guard cells are two bean-shaped cells that surround a stoma. As epidermal cells, they play an important role in gaseous exchange in and out of plant leaves by regulating the opening and closing of pores known as a stoma. In addition, they are the channels through which water is released from leaves to the environment. As such, guard cells play a crucial role in photosynthesis by regulating the entry of materials necessary for the process. Apart from regulating gaseous exchange (as well as water release from leaves), they have also been shown to contain chloroplasts which also make them a site of photosynthesis. Some of the factors that influence guard cell activities include: 1. Humidity 2. Temperature 3. Light 4. Carbon dioxide 5. Potassium ions 6. Hormones *In Greek, the word "stoma" means mouth. *Although stomata are commonly found in plant leaves, they can also be found in the stems. (e)€€€€€The diagram below shows two guard cells surrounding a closed stoma and two guard cells surrounding an open stoma. € When light intensity is high potassium ions are moved into the guard cells.

Guard Cells These cells resemble the shape of a kidney or dumbbell-shaped that consists of the chloroplast. They contain chlorophyll and capture light energy. The primary function of guard cells is to properly carry out the opening and closing mechanism of the stoma. Guard cells have numerous ectodesmata.The guard cells become turgid when the water concentration is high within the cell than the surrounding. Conversely, the low concentration of water within the cell than the surrounding makes the guard cells flaccid.. Organelles within the guard cells: Microtubules orient cellulose microfibrils and contribute to building guard cells. Create a labeled diagram that explains how guard cells sense blue light and respond by becoming turgid. Include PHOT, H+ pump, hyperpolarization-gated K+ channels, H+/solute cotransporters, solute concentration, H2O, and pressure potential. B-represents guard cells. kigney shaped and dumbel shaped respectively. C-represent subsidiary cells - epidermal cells surrounding the guard cells, maintain turgor pressure of the guard cells. So, the correct answer is ' A-Stoma ,B-Guard cells,C- Subsidiary cells'

The guard cells are bean-shaped in dicots and dumb-bell shaped in monocots. The inner wall of the guard cell is thick whereas the outer wall is thin. Plants need gases like oxygen for respiration and carbon dioxide for photosynthesis. It is through this small opening called stomata the gases diffuse inside the leaf and are taken in.
