How do cells live if they do not have cells in them?

Answer 1

Biological cells are the fundamental structure of all living organism. They are nourished by oxygen and nutrients provided by the bloodstream. So they needn't to have anything else in them besides their natural elements. The human body has trillions of cells, and each one of them works to maintain us alive. Although cells are the smallest part of our organism, they have a complex structure which is necessary to make them operational. There is a subunit of the cell called organelle that has an specific function and is very complex too. An organelle is composed by the following elements :

(1) Nucleolus

(2) Nucleus

(3) Ribosomes

(4) Vesicle

(5) Rough endoplasmic reticulum (ER)

(6) Golgi apparatus

(7) Cytoskeleton

(8) Smooth ER

(9) Mitochondria

(10) Vacuole

(11) Cytosol

(12) Lysosome

(13) Centrioles within Centrosome

Summarizing, since the organelle is inside of a cell, the cell itself represents the main structure of a living organism, and it is a part of the cell: the organelle isn't a cell, but a component of it.

The name organelle comes from the idea that these structures are to cells what an organ is to the body (hence the name organelle, the suffix -elle being a diminutive).
