What is longest cell in human body?

Neurons or nerve cells can be up to 3 feet long. A typical neuron has a cell morphology called soma, hair-like structures called dendrites and an axon. Neurons are specialized in conveying knowledge throughout the body.

Which cell is the smallest?

Why the cell is called the structural and functional unit of life?

The cell is called the structural and functional unit of life as all living organisms are made up of cells. … Furthermore, cells provide form and structure, process nutrients and convert it into useable energy. Multicellular organisms have specialized cells that perform specific functions.

Why is cell called building block of life?

Cells are the basic building blocks of living things. … Cells provide structure for the body, take in nutrients from food and carry out important functions. Cells group together to form tissues?, which in turn group together to form organs?, such as the heart and brain.

Which is the largest cell?

What is the smallest unit of life?

cellThe cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life. Some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.

What is the basic unit of life?

Cells as the Basic Unit of Life. A cell is the smallest unit of a living thing and is the basic building block of all organisms.

How cell is formed?

New cells are created from existing cells through a process referred to as the cell cycle. One cell can make a copy of itself and form two new daughter cells. There are two major tasks that have to happen every cell cycle. First, cells have to make an exact copy of their DNA.

What is a cell?

Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. … Cells have many parts, each with a different function. Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell.

How does cell maintain life?
