The function of leaves is to help the plant produce food by converting the energy in sunlight into chemical energy that the plant can eat. The structures within the leaf convert the energy and make it possible for the plant to get food.Know More
Chlorophyll is the molecule in the structure of the leaves that takes the energy in sunlight to turn water and carbon dioxide gas into sugar and oxygen gas. This conversion process is known as photosynthesis.
Leaves are made out of several layers that are in between two layers of super tough skin cells called epidermis. The epidermis is also known to secrete cuticle, which is a waxy substance. All of these layers protect the leaf from pests such as insects and bacteria. There are also stomata cells that are pores where gases can enter and exit through the leaf.
Most of the food production in the leaf actually takes place in the elongated cells that are known as palisade mesophyll inside the leaf. The leaf also has veins that can help to support the leaf by transporting food, water and minerals to the leaf and to the plant.
Leaves are also important for humans as they are one of the best ways to identify various plants. Leaves come in many shapes and sizes, such as flat, wide, spiky, thin, rectangular and oval.Learn more about Botany
Plant growth is caused by water that is absorbed by the plant's roots and sunlight that spurs photosynthesis, which is the process of creating food for the plant. Plants also need space, time, clean air, healthy soil and nutrients to grow. The main ingredients that plants need are phosphorous, nitrogen and potassium.Full Answer >
Photosynthesis is the process that plants use to convert the energy in sunlight into food that they use for energy. In order to carry out photosynthesis, plants need not only sunlight but also water and carbon dioxide. The food they make is called glucose, which is a simple sugar.Full Answer >
A plant's organ system works with the roots anchoring the plant and absorbing water and nutrients, while the shoots transfer the nutrients to the leaves, which transfer light into energy via photosynthesis. A plant’s roots, leaves and stems, the three basic plant organs, work together to allow the plant to function. The plant’s shoot system, which includes the leaves, stems, and flowers, is divided into two sections: the non-reproductive portion and the reproductive portion. The reproductive portion includes the flowers and fruit. The non-reproductive portion includes the leaves and stems.Full Answer >
The main function of xylem cells is to carry water and soluble minerals from the root to the leaves of a plant. However, a secondary function of xylem tissue is to provide support for the plant. Xylem is present in vascular plants and is made up of different types cells, such as tracheids, fibers and parenchyma.Full Answer >
