Mainly they are not.Leaves do the main job
The epidermis protects the underlying tissues. The cuticle prevents the desiccation of inner tissues and thus prevents water loss . The stomata allows gaseous exchange for the processes of respiration and photosynthesis.
approx 80% is taken in through their root system the rest through gaseous exchange.
The endodermis, a specialized layer of cells, surrounds and borders the stele of a dicot root. It is responsible for regulating the passage of water and nutrients into the vascular tissues of the root.
1. Differentiation of plant body into stem, root and leaves. 2. Development of stomata for gaseous exchange.
Root organ contains root hair tissues
The two main tissues that make up a plant root are the xylem and the phloem. Xylem tissue is responsible for transporting water and minerals from the roots to other parts of the plant, while phloem tissue is responsible for transporting sugars produced by photosynthesis from the leaves to other parts of the plant.
the root of the plant die .....?
the root of the plant die .....?
The tissues of the stem tip are primary tissues, which are derived from the apical meristem. Secondary tissues, on the other hand, are produced by the lateral meristem (vascular cambium and cork cambium) and are responsible for increasing the girth of the stem over time.
The prefix of the word exchange is ex.
The innermost cylinder of a root is composed of vascular tissue called the stele. The stele consists of the vascular tissues xylem and phloem, which are responsible for transporting water, nutrients, and sugars throughout the plant.
pneumatophores are lateral roots that grow upward (negative geotropism) for varying distances and function as the site of oxygen intake for the submerged primary...or they are a specialized root of certain swamp plants, such as the mangrove, that branches upwards, rising above ground, and undergoes gaseous exchange with the atmosphere.Pneumatophores are aerial roots that are specialized for gaseous exchange and are found in swamp plants and mangroves.
