What is the function of the lamina?

The basal lamina helps to attach and anchor the cells to the underlying connective tissue. Proteins (integrins and proteglycans) in the cell membranes attach to proteins in the basal lamina, which in turn is linked to the extracellular matrix of connective tissue.

How leaves help plants?

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. Green plants such as trees use carbon dioxide, sunlight, and water to create sugars. Sugars provide the energy that makes plants grow.

What is the function of phloem?

While the main role of the phloem tissue is to transport carbohydrates from sources to sinks through the sieve elements, phloem is also composed of parenchyma cells, which play a key role in the storage of water, non-structural carbohydrates and storage proteins (Rosell 2016).

Where does stomata located in plant?

The majority of stomata are located on the underside of plant leaves reducing their exposure to heat and air current. In aquatic plants, stomata are located on the upper surface of the leaves.

What are plant veins?

The veins are the vascular tissue of the leaf and are located in the spongy layer of the mesophyll. The pattern of the veins is called venation. In angiosperms the venation is typically parallel in monocotyledons and forms an interconnecting network in broad-leaved plants.

What is the difference between lanceolate and oblanceolate leaves?
