Plants have a vital role in the ecology. Plants are essential to all life on the planet, whether directly or indirectly. The leaf is the most important of all the parts of a plant. Photosynthesis and transpiration are the two primary functions of leaves. In some plants, it also takes on ...

The meaning of LEAF is a lateral outgrowth from a plant stem that is typically a flattened expanded variably shaped greenish organ, constitutes a unit of the foliage, and functions primarily in food manufacture by photosynthesis. How to use leaf in a sen
Whole leaves or parts of leaves are often modified for special functions, such as for climbing and substrate attachment, storage, protection against predation or climatic conditions, or trapping and digesting insect prey. Intemperatetrees leaves are simply protective bud scales; in the spring when sho...
Vascular tissue is within the mesophyll tissue and brings water and nutrients to the cells. Many of the plant's important parts and functions are located within the mesophyll tissue. The epidermis, however, also plays a crucial role in the survival of the plant....

Dermal tissuemakes up the outer region of the plant and functions in mechanical protection of inner tissues and inhibition of water loss. Dermal tissue consists of theepidermisor, inwoody plants, theperiderm(see later discussion). Theepidermis(Figure 10.10) makes up the outermost layer of all pri...
A complete dicotyledon leaf consists of three parts: the expanded portion or blade; the petiole which supports the blades; and the leaf base. Stipules are small appendages that arise as outgrowths of the leaf base and are attached at the base of the petiole. The leaves of monocotyledons may...
methemoglobin reduction is impaired.89,91Although methemoglobin itself does not produce hemolysis, it is incapable of transporting oxygen and therefore contributes tohypoxia. When present in sufficient quantities, methemoglobin imparts a brown discoloration to peripheral blood and possibly to mucous ...
