They contain a network of small tubes that runs between the roots and the leaves, thus acting as the plumbing system in the plant. Stems. It also produces lysosomal enzymes and sends them to their required destinations. These roots grow outward into the air instead of growing underground in soil, and absorb moisture from humid air to survive. A typical tree trunk shows six parts: i) Outer bark: The outermost layer of the trunk, branches, and twigs of the tree. It also helps to reduce water loss from the living cells of the tree. Leaves are the food factories of a tree. bronchi. Denise Wawrzyniak/Wikimedia Commons . It is responsible for coordinating all of the metabolic functions, including cell growth, protein synthesis, and cell division. This part of the tree holds medicinal properties. The roots of a plant are the lower section of the plant attached to the stem at its base. The cerebrum is the largest part of the brain. It is made predominantly from cellulose fiber and also has the function of preventing the cell from growing too big. Plant cells are known as eukaryotic cells. The root system of the plant provides physical support by anchoring the plant body to the soil. As chlorophyll is essential to perform photosynthesis, these leaves will typically require higher levels of sunlight in order to thrive. Some stems perform the function of storage of food, support, protection and of vegetative propagation. The first thick branches of a tree arising from the central wooden axis are called.
