Which defines a cell?

A cell is a mass of cytoplasm that is bound externally by a cell membrane. Usually microscopic in size cells are the smallest structural units of living matter and compose all living things. Most cells have one or more nuclei and other organelles that carry out a variety of tasks.

How many cells are made up of the human body?

Humans are complex organisms made up of trillions of cells each with their own structure and function. Scientists have come a long way in estimating the number of cells in the average human body. Most recent estimates put the number of cells at around 30 trillion. Written out that’s 30 000 000 000 000!

What are the parts of the cell and its function?

The parts of the cell that are organized for specific functions are called organelles. The organelles include such structures as the nucleus and the mitochondria. The nucleus contains the genetic material and the mitochondria convert energy. … Each of these organelles has a special role to play in the way the cell works.

What is cell made up of answer?
