tissue, in physiology, a level of organization in multicellular organisms; it consists of a group of structurally and functionally similar cells and their intercellular material.
What is tissue in biology short answer?
In biology, tissue is a biological organizational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.
What is tissue class 9 biology?
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. Different types of tissues are found in plants and animals.
Why is a tissue called a tissue?
The noun tissue comes from the Old French word tissu, meaning “a ribbon, or belt of woven material.” In fact, as a verb, tissue means “weave fabric strands.” Today, we think of tissues as the disposable paper for blowing our noses or packing presents.

What is tissue class 9th question?
Answer: Plant tissues consist of two main types of tissue. Parenchyma: Present in soft parts of the plant. Collenchyma: Provides mechanical support to plant present in stalks. Sclerenchyma: They provide strength and flexibility to the plants.
What is tissue made of?
What is Tissue? Tissue products are soft, thin, pliable, and absorbent paper made from wood or recycled paper.
What is a cell and tissue?
Cells are the smallest, structural and functional unit of an organism, which are characteristically microscopic. Tissues are distinct types of material consisting of specialized cells and their products. Found in both unicellular and multicellular organisms. Found only in multicellular organisms.
How tissue is formed?
Tissues are formed from the assemblage of cells and intercellular materials in various proportions in which one component predominates. In nervous tissue as an example, nerve cells predominate while in connective tissues such as Ligaments and Tendons, intercellular fibrous materials predominate.
What are the function of tissue?
Epithelial tissues act as coverings, controlling the movement of materials across their surface. Connective tissue binds the various parts of the body together, providing support and protection. Muscle tissue allows the body to move and nervous tissues functions in communication.
Who invented tissue in biology?
1) The term ’tissue’ was introduced by Xavier Bichat in the year 1801. He was the first person to propose that tissue is a central element in human anatomy and he considered that the organs are collections of many tissues.
Is bone a tissue?
Tissue that gives strength and structure to bones. Bone is made up of compact tissue (the hard, outer layer) and cancellous tissue (the spongy, inner layer that contains red marrow). Bone tissue is maintained by bone-forming cells called osteoblasts and cells that break down bone called osteoclasts.
What is tissue very short?
Answer: Tissue is a group of cells having similar structure and function together as a unit . There are four main types of tissues in the body – epithelial , connective , muscle and nervous tissue . All the body parts are made up of tissues including the organs.
What is a tissue class 11?
A tissue, in biology, is defined as a group of cells that possess a similar structure and perform a specific function. The word tissue originates from French, which means “to weave.”
What is tissue system?
Tissue systems can be defined as how various groups of tissues and their types function differently based on their location. The three tissue systems that perform the major functions are the epidermal tissues system, ground tissue system and vascular tissue system.

What is tissue class 7th?
Answer: Tissue is a group of cells that are similar in structure and are organised together to perform a specific task.
Why are tissues important class 9?
A group of tissue forms an organ. The tissues are essential because it represents a level of organisation in living organisms. Tissues also function by transporting nutrients and connects bones and other body parts.
