What Is The Structural Unit Of An Organ?

What is the structural and functional unit of the nervous system called?

Neurons, or nerve cell, are the main structural and functional units of the nervous system.

Every neuron consists of a body (soma) and a number of processes (neurites)..

What is the structural unit of cell?

The cell (from Latin cella, meaning “small room”) is the basic structural, functional, and biological unit of all known organisms. A cell is the smallest unit of life. Cells are often called the “building blocks of life”….Cell (biology)CellTHH1. terminology4 more rows

Why is the cell called structural unit?

Cell is known as the structural and functional unit of life because it is the smallest and basic unit of any system. A cell is the smallest structure functions independently and no further small unit can exit and perform all function.

What is the functional unit of cell?

Although we defined the cell as the “most basic” unit of life, it is structurally and functionally complex (Figure 2.2. 1). A cell can be thought of as a mini-organism consisting of tiny organs called organelles. The organelles are structural and functional units constructed from several macromolecules bonded together.

What do you mean by structural unit?

From Wikipedia, the free encyclopedia. In polymer chemistry, a structural unit is a building block of a polymer chain. It is the result of a monomer which has been polymerized into a long chain. There may be more than one structural unit in the repeat unit. When different monomers are polymerized, a copolymer is formed …

What is the structure and functional unit of brain?

Neurons. The basic functional unit of the brain is the neuron. … Although there are upwards of 1,000 different types of neurons, they all have the same basic structure and function. Each neuron has a soma, or cell body, that performs all the basic metabolic functions required to keep the cell alive and functioning.

Which is the largest part of the brain?

CerebrumCerebrum: is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement. Cerebellum: is located under the cerebrum.

What is the basic structural unit of an organ?

In this chapter, you shall learn about the basic structural unit of an organ, which is the cell. Cells may be compared to bricks. Bricks are assembled to make a building. Similarly, cells are assembled to make the body of every organism.

What is the basic structural unit of brain?

NeuronsNeurons are the structural and functional units of the nervous system. They transmit electrical signals, called nerve impulses. Glial cells provide support for neurons.

Which is largest cell?

ovumThe largest cell is ovum in the human body. The ovum also called egg cell is the reproductive cell in the female body. Ovum is 20 times bigger than the sperm cells and has a diameter of about 0.1 mm.

What is Plasmolysis?

: shrinking of the cytoplasm away from the wall of a living cell due to outward osmotic flow of water.
