What is the tissue differentiation?
Tissue differentiation in multicellular organisms is thus brought about by the expression of different subsets of genes in different cell lines.
What is differentiation in tissue chapter?
The process in which the meristematic tissues take a permanent shape, size and function is known as differentiation. This implies the cells of meristematic tissues differentiate to form different types of permanent tissues.
What is tissue differentiation Class 9?
In reference to biology, Differentiation is a process in which cells, tissues, organs acquire certain characteristics and features which makes them specialized in the function they perform. For example, differentiation of meristem into specialized cells and tissues like plants and stems.
How can you differentiate cell from tissue?
Cells are the smallest, structural, and functional unit of an organism. Tissues are the distinct types of material consisting of specialized cells and also types of their products. Cells are microscopic. Tissues are macroscopic.
What is cell differentiation 8?
Cell differentiation is the process by which a less specialized cell goes through development and maturation in order to become more distinct in terms of form and function.The cell size, shape, polarity, metabolism and responsiveness to signals change dramatically during differentiation.These changes are brought about …
What is plant tissue class 9?
Plant tissues are of two main types meristematic and permanent. Meristematic tissue is the dividing tissue present in the growing regions of the plant. Permanent tissues are derived from meristematic tissue once they lose the ability to divide. They are classified as simple and complex tissues.
What is differentiation in biology class 12?
Differentiation – It is a process in which the cells derived from the apical meristem (root and shoot apex) and the cambium undergo structural changes in the cell wall and the protoplasm, becoming mature to perform specific functions.
What is differentiation in bio class 11?
Hint:Cell differentiation is the process in which differentiation or the division of cells occurs to give rise to specific functions. The cells that can divide and give rise to differentiated cells are known as stem cells. In animals, an embryo differentiates into various cells giving rise to a fetus.
What is cell differentiation for Class 8?
Cell differentiation is an important process whereby a single cell gradually develops various tissues and organs. It helps in the development of an organism from a single cell zygote.
What is a tissue in biology class 9?
Tissue is a feature of multicellular organisms. Complete Answer: A group of cells having similar shape and function act together to perform a specific function is known as a tissue. All the body parts are made up of tissues including the organs. Groups of tissues make organs.
What is an example of cell differentiation?
An example of cell differentiation is the development of a single-celled zygote into a multicellular embryo that further develops into a more complex multisystem of distinct cell types of a fetus. A cell that underwent differentiation is described as differentiated.
What is meant by differentiation Class 11?
Differentiation is a process by which we can measure the rate of change of some quantity with respect to another quantity. These rates we get after differentiation are called derivatives. Suppose that we have a function y=f(x). Now, this is a function which has an independent variable x and a dependent variable y.
What is the first step in tissue differentiation?
The division of the original mass of indifferent cells into two layers of special cells is the first step toward tissue differentiation, and in some animals is the only one arrived at in their life history, throughout which they remain a simple sac made up of an external layer, Ectoderm, and an internal layer, Endoderm.
Is it possible to separate the differentiation of tissues and organs?
It is impossible to separate the differentiation of tissues and organs, or to say which is of older date in the history of animal evolution.
What is the difference between meristematic tissue and permanent tissue?
Meristematic tissue is analagous to stem cells in animals: m eristematic cells are undifferentiated 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.
What is the relationship between plant organs tissues and cell types?
The relationships between plant organs, tissues, and cell types are illustrated below. The stems and leaves together make up the shoot system. Each organ (roots, stems, and leaves) include all three tissue types (ground, vascular, and dermal).
