What is the function of the transport system in plants?
Plants have two transport systems – xylem and phloem . Xylem transports water and minerals. Phloem transports sugars and amino acids dissolved in water.
What are the specialized structures of plants?
Just as people have tissues and organs, plants also have specialized tissues and structures. The tissues and structures make up two broad systems: the shoot system and the root system. The shoot system is made up primarily of leaves, stems, and reproductive structures (e.g., flowers, fruit, seeds, etc.)
What are the structures of plants and their functions?
The three main parts are: the roots, the leaves, and the stem. Each part has a set of jobs to do to keep the plant healthy. The roots absorb water and minerals from the soil and anchor the plant in the ground. The stem supports the plant above ground, and carries the water and minerals to the leaves.
What is the function of the phloem?
Phloem is the vascular tissue in charge of transport and distribution of the organic nutrients. The phloem is also a pathway to signaling molecules and has a structural function in the plant body. It is typically composed of three cell types: sieve elements, parenchyma, and sclerenchyma.
What are the four components of phloem?
Phloem is composed of various specialized cells called sieve tubes, companion cells, phloem fibres, and phloem parenchyma cells.
What is the structure and function of xylem?
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.Mehr 26, 1392 AP
What are the features of xylem?
The xylem is a tissue which transports water and minerals from the roots up the plant stem and into the leaves. Xylem consists of dead cells. The cells that make up the xylem are adapted to their function: They lose their end walls so the xylem forms a continuous, hollow tube.
What are cork cells and their functions?
A mature cork cell is non-living and has cell walls that are composed of a waxy substance that is highly impermeable to gases and water called suberin. The layer of dead cells formed by the cork cambium provides the internal cells of the plants with extra insulation and protection. …
What is another name of Phellogen?
cambium, called the phellogen or cork cambium, is the source of the periderm, a protective tissue that replaces the epidermis when the secondary growth displaces, and ultimately destroys, the epidermis of the primary plant body.
What is another name for cork cambium?
Synonyms for cork cambium are bark cambium, pericambium and phellogen. Phellogen is defined as the meristematic cell layer responsible for the development of the periderm.
