what are tissues? give 2 examples.
Answers
Tissue is a group of cell having a similar structure and have a specific function, the tissues function as a single unit.
Explanation:
Tissue is a group of cell having a similar structure and have a specific function, the tissues function as a single unit. Cell is the basic functioning unit of a living organism. These are closely connected and function on specific functions, each tissue is assigned with a function.
Plant tissues
Tissues in plants are typically bifurcated into two, Meristematic and Permanent tissue.
Meristematic cells are undifferentiated dividing cells and to contribute towards the growth of a plant. These produce cells rapidly to form permanent tissues, the cells are specifically modified and loose the ability to divide continually. These majorly form dermal, vascular and ground tissues. Each of these three are further comprised into several complex tissues with specific functions to perform.
Animal tissues
The tissues of animals are similar to plants but have functions modified to suit animal metabolism. They are classified into four major types: Epithelial tissue, Connective tissue, Nervous tissue and the muscular tissue. Each of these types have cells of varying structures and shapes with a function to carry on.
Every tissue is designated with a specific function based on where it is located. Some of the majorly taking place functions ae movement, secretion, excretion, communication, etc.
Tissue is a collection of cells that have a similar structure and perform a certain function; tissues work as a single unit.
Explanation:
- Tissue is a collection of cells that have a similar structure and perform a certain function; tissues work as a single unit. A cell is a biological organism's basic functional unit. These are intertwined and perform certain purposes; each tissue is assigned a role.
Tissues from plants
- Meristematic and Permanent tissue are two types of tissue found in plants.
- Meristematic cells are undifferentiated dividing cells that help a plant develop. These rapidly create cells to construct permanent tissues, but the cells are genetically changed and lose their capacity to divide. Dermal, vascular, and ground tissues are the most common types. Each of these three is further subdivided into a number of complicated tissues that execute distinct roles.
Tissues of animals
- Animal tissues are comparable to plant tissues, but their activities have been altered to suit animal metabolism. Epithelial tissue, connective tissue, nervous tissue, and muscle tissue are the four primary categories. Each of these categories has cells with different structures and forms that serve a purpose.
- Each tissue is assigned a distinct function depending on its location. Movement, secretion, excretion, communication, and other functions are among the most important ones.
