What is the function of phloem in a plant?
Phloem is the vascular plant tissue responsible for the transport and distribution of sugars produced by the photosynthesis.
What will happen if stomata will not open?
If stomata is not present in plants plants will not be able to breathe….. mean plants will not be able to take co2 in and because of this process of photosynthesis will not take place and plant will not able to make their food and will not release o2 which is necessary for human beings to live.
What affects the opening and closing of stomata?
The four factors affecting opening and closing of stomata are: (1) Light (2) Water Content of Epidermal Cells (3) Temperature and (4) Mineral Elements.
What time of day are stomata generally open?
Two Main Functions of Stomata 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. In photosynthesis, plants use carbon dioxide, water, and sunlight to produce glucose, water, and oxygen.
What are the two function of stomata?
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.
What are 2 Functions of leaves?
Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close. They regulate carbon dioxide, oxygen, and water vapour exchange with the atmosphere.
What are the two main functions of leaves?
- Manufacturing of food/ photosynthesis: the main function of leaves is to manufacture food. Food is manufactured in the presence of sunlight by leaves that contain a green pigment called chlorophyll.
- Transpiration : excess water taken up by the plants is released into the air in the form of water vapour through stomata.
What is the primary function of leaves?
The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.
