What is called the basic unit of life?

A cell is the most basic unit of life. Anatomically, it is a membrane-bound structure that contains various other organelles which perform specialized functions.

What is the largest unit of life?

The levels, from smallest to largest, are: molecule, cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere.

What cell is smallest?

Mycoplasma gallicepticum
The smallest cell is Mycoplasma gallicepticum. It is about 10 micrometer in size.

What are all cells made of?

Cells are composed of water, inorganic ions, and carbon-containing (organic) molecules. Water is the most abundant molecule in cells, accounting for 70% or more of total cell mass. Consequently, the interactions between water and the other constituents of cells are of central importance in biological chemistry.

What is smaller than a cell?

Cells contain molecules that are made up of evensmaller components called atoms. Figure 1: Levels of the body from smallest to largest: Atoms, molecules,cells, tissues, organs, and organ systems.

What are two types of organelles?

In this regard, there are two types of organelles: (1) membrane-bound organelles (included are double-membraned and single-membraned cytoplasmic structures) and (2) non-membrane-bound organelles (also referred to as biomolecular complexes or proteinaceous organelles).
