what is the most important function for a plant?
10312
The most vital function is the process of converting carbon dioxide into oxygen. Secondarily the leaves and branches collect dust and dirt from the air and then provide pathways back to the ground when it rains.

Xylem is a type of tissue in plants. It role is to transport water and minerals/nutrients to all parts of the plant.

The main job of a leaf is to make food (see left navigation for a separate page about this) for a plant. Leaves do this by using sunlight for energy to take apart water from the ground and carbon dioxide from the air. Leaves use parts of water and carbon dioxide to make sugar.

Xylem is the specialised tissue of vascular plants that transports water and nutrients from the plant–soil interface to stems and leaves, and provides mechanical support and storage. The water‐conducting function of xylem is one of the major distinguishing features of vascular plants.

Plants are multicellular, meaning they are made of many cells. If plant cells survive, the plant survives. In order to live and provide proper function to the plant, plant cells need oxygen, energy from the sun, minerals/nutrients, and water.

Plants 'breathe' and 'sweat' through their stomata, which are regulated by guard cells. Guard cells have a very important job because by opening and closing stomata, they facilitate gas exchange for photosynthesis and help minimize water loss.

cell wall. The cell wall is the protective, semi-permeable outer layer of a plant cell. A major function of the cell wall is to give the cell strength and structure, and to filter molecules that pass in and out of the cell.

The characteristics of life that plants must fulfill are: Use energy, Maintain homeostasis, and Composed of cells.

The main functions of the cell wall are to provide structure, support, and protection for the cell. The cell wall in plants is composed mainly of cellulose and contains three layers in many plants. The three layers are the middle lamella, primary cell wall, and secondary cell wall.

Among its roles in plant cell function, the central vacuole stores salts, minerals, nutrients, proteins, pigments, helps in plant growth, and plays an important structural role for the plant.

The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transport these products from the leaves to other parts of the plant, including the roots.

The leaves perform three main functions such as manufacture of food, interchange of gases between the atmosphere and the plant body and evaporation of water. It is the primary function of green leaves.
