What is tissue and its definition?
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 a cell simple definition?
In biology, the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body.
Which answer is the best definition for tissue?

What is the definition of a tissue quizlet?
tissue. a group of biological cells that perform a similar function. histology. the study of tissues.
Why is a tissue called a tissue?
The English word “tissue” derives from the French word “tissu”, the past participle of the verb tisser, “to weave”. The study of tissues is known as histology or, in connection with disease, as histopathology.
How is a cell related to a tissue?
Living tissue is made up of cells. There are many different types of cells, but all have the same basic structure. Tissues are layers of similar cells that perform a specific function. The different kinds of tissues group together to form organs.
What’s an example of a tissue?
Examples of connective tissue include blood, bone, adipose, tendons, and ligaments. In humans, cranial bones derive from the ectoderm, but the other connective tissues come from the mesoderm.
What are the function of a cell?
Cells provide six main functions. They provide structure and support, facilitate growth through mitosis, allow passive and active transport, produce energy, create metabolic reactions and aid in reproduction.
What is a tissue answer in one sentence?
Tissues are groups of cells that have a similar structure and act together to perform a specific function. The word tissue comes from a form of an old French verb meaning “to weave”. Groups of tissues make up organs in the body such as the brain and heart.
What are tissues for?
Overview. There are 4 basic types of tissue: connective tissue, epithelial tissue, muscle tissue, and nervous tissue. Connective tissue supports other tissues and binds them together (bone, blood, and lymph tissues). Epithelial tissue provides a covering (skin, the linings of the various passages inside the body).
What is the difference between a cell and a tissue?
Cells are the smallest, structural and functional unit of an organism, which is characteristically microscopic. Tissues are the distinct types of material consisting of specialized cells and their products. Found in both unicellular and multicellular organisms. Found only in multicellular organisms.
What is a cell for 6th grade?
The cell is the smallest unit with the basic properties of life. Some tiny organisms, such as bacteria and yeast, consist of only one cell. Large plants and animals have many billions of cells. Human beings are made up of more than 75 trillion cells.
What is 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.

What is an example of a tissue cell?
When cells of a certain type are grouped together, the resulting structure is called tissue. There is muscle tissue, which is made of strands of muscle cells. Adipose tissue is one layer of skin made of fat cells. Connective tissue is a term used for various types of tough, fibrous matter like tendons or ligaments.
What is the difference between cells and tissues?
The very basic and fundamental difference between Cell and Tissue is that a Cell is the very smallest unit of an organism and can only be seen at the microscopic level WHILE a Tissue is made by joining several cells together and can be seen at the macroscopic level or with naked eyes.
What are the four types of tissues?
– Extensibility- the ability of a muscle to stretch itself – Contractibility- the ability of the muscle cells to forcefully shorten themselves – Excitability- the ability of a muscle tissue to respond to a stimulus given by any hormone or a motor neuron – Elasticity- the ability of a muscle to recoil to it’s usual length after being stretched
What are the 4 main tissue types?
– Epithelial Tissue – Connective Tissue – Muscle Tissue – Nervous Tissue
