Parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with least differentiation, to various functions. Parenchyma makes up the chloroplast-laden mesophyll (internal layers) of leaves and the cortex (outer layers) and pith (innermost layers) of stems and roots; it also forms the soft tissues of fruits.
Complex Tissue Structure. A hallmark trait of animals is specialized structures that are differentiated to perform unique functions. As multicellular organisms, most animals develop specialized cells that group together into tissues with specialized functions.
Parenchyma makes up the chloroplast-laden mesophyll (internal layers) of leaves and the cortex (outer layers) and pith (innermost layers) of stems and roots; it also forms the soft tissues of fruits. Meristematic tissue cells are either undifferentiated or incompletely differentiated, and they continue to divide and contribute to the growth of the plant. In contrast, permanent tissue consists of plant cells that are no longer actively dividing. Meristematic tissues consist of … Manipal 2005: Which of the following tissues is phylogenetically least differentiated ?

Plant Tissues. A mature vascular plant (any plant other than mosses and liverworts), contains several types of differentiated cells. These are grouped together in tissues. Some tissues contain only one type of cell. Some consist of several. Meristematic. The main function of meristematic tissue is mitosis.

An experimental project which examines the commitment of plant tissues to the differentiated state. One of the challenges in teaching biology is designing laboratory exercises that introduce important concepts and techniques, provide some latitude for independent study, and which are not prohibitively expensive.
In contrast, permanent tissue consists of plant cells that are no longer actively dividing. Meristems produce cells that quickly differentiate, or specialize, and become permanent tissue. Such cells take on specific roles and lose their ability to divide further. Plant Tissues. A mature vascular plant (any plant other than mosses and liverworts), contains several types of differentiated cells. These are grouped together in tissues. Some tissues contain only one type of cell.
Is the "main axis" of a plant that elongates and produces leaves. "Nodes" occur where leaves are attached to the stem. "Internode" is the region between nodes. At the stem end, a "Terminal bud" contains an apical meristem and produces new leaves. Stem also has "vascular tissue" that transports water and minerals.
Its cells have thick, hard walls. Xylem tissue dies soon after it is formed and is the wood in the middle of a tree. The dead cells are like pipes, hollow and rigid.. Xylem is one of two tissues in the plant which transport substances that plants need to live. Substances that xylem transports include water and minerals obtained through the plant's roots Parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with least differentiation, to various functions.

Meristematic tissue cells are either undifferentiated or incompletely differentiated, and they continue to divide and contribute to the growth of the plant.
