what are stomata responsible for?
79870
They are pores surrounded by specialized parenchymatic cells, called guard cells. Stomata have two main functions, namely they allow for gas exchange acting as an entryway for carbon dioxide (CO2) and releasing the Oxygen (O2) that we breath. The other main function is regulating water movement through transpiration.

The two main functions of stomata are to allow for the uptake of carbon dioxide and to limit the loss of water due to evaporation. In many plants, stomata remain open during the day and closed at night. Stomata are open during the day because this is when photosynthesis typically occurs.

Image caption: Carbon dioxide enters, while water and oxygen exit, through a leaf's stomata. Stomata control a tradeoff for the plant: they allow carbon dioxide in, but they also let precious water escape.

Xylem is the vascular tissue responsible for the transport of water and nutrients from the roots in the soil to the above-ground parts of the plant. ... The TE are completely dead at maturity, and act like pipes to allow water and dissolved minterals to flow through them.

Introduction. Leaves provide food and air to help a plant stay healthy and grow. Through photosynthesis, leaves turn light energy into food. Through pores, or stomata, leaves “breathe” in carbon dioxide and “breathe” out oxygen.

Stomatal pores in plants regulate the amount of water and solutes within them by opening and closing their guard cells using osmotic pressure. In order for plants to produce energy and maintain cellular function, their cells undergo the highly intricate process of photosynthesis. Critical in this process is the stoma.

Xylem transports water and soluble mineral nutrients from roots to various parts of the plant. It is responsible for replacing water lost through transpiration and photosynthesis. Phloem translocates sugars made by photosynthetic areas of plants to storage organs like roots, tubers or bulbs.

Plants take carbon dioxide (CO2) out of the atmosphere to do photosynthesis, and thus help reduce the greenhouse gases warming the planet. ... This increased warming results from plant leaves' natural reaction to high CO2 environments. Plant leaves have tiny vents called stomata that open or close to let the plant breathe.

Most stomata are located on the bottom of leaves, or the ventral portion. The main reason for this is to control water loss from evaporation, as water...

The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis. The central leaf, or mesophyll, consists of soft-walled, unspecialized cells of the type known as parenchyma. ... Oxygen is passed into the atmosphere through stomata—pores in the leaf surface.

Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata.

Tracheids are tubular cells in the xylem of vascular plants, involved in the conduction of water from the roots to the leaves. Vessels are elongated dead cells found in the xylem of flowering plants, consisting of perforated cell walls throughout which the water flows.

Main function – upwards water transport. The xylem, vessels and tracheids of the roots, stems and leaves are interconnected to form a continuous system of water-conducting channels reaching all parts of the plants. The system transports water and soluble mineral nutrients from the roots throughout the plant.

Light increases the rate of water absorption and the resulting increased turgidity of the two guard cells, which form the boundary of each stoma, brings about the opening of the stomates, increasing transpiration rate.
