- The leaf is one of the most important organs of a plant. Leaves produce food for the plant through a process called photosynthesis. The leaves of different plants vary widely in size, shape and colour and are adapted to carry out photosynthesis.

The term leaf refers to the organ that forms the main lateral appendage on the stem of vascular plants. In general, leaves are thin, flat organs responsible for the photosynthesis of the plant. Although photosynthesis typically only occurs on the upper surface of the leaf, it can occur on both sides in some plant species. Leaves are typically compr...
In general, the types of leaf can be divided into six major types, although there are also plants with highly specialized leaves:

Which of the following statements is TRUE regarding guttation: A. It typically occurs at night. B. It occurs when the stomata are closed. C. It results from increased water pressu...
Jul 12, 2023 · In the leaves of the plant is a compound called chlorophyll which it uses to absorb sunlight. Plants have xylem which is similar in function to human veins. They carry water and nutrients that the plant takes from the soil using its roots, to other parts of the plant, including the leaves.
Oct 31, 2023 · The xylem transports water and minerals to the leaves; the phloem transports the photosynthetic products to the other parts of the plant. Plants in cold climates have needle-like leaves that are reduced in size; plants in hot climates have succulent leaves that help to conserve water.
Leaves are the main sites for photosynthesis: the process by which plants synthesize food. Most leaves are usually green, due to the presence of chlorophyll in the leaf cells. However, some leaves may have different colors, caused by other plant pigments that mask the green chlorophyll.
Oct 24, 2024 · 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.
