Cell - fundamental unit of Biology, building block of all organisms
1) Unicellular: 1 cell = 1 organism
2) Multicellular: 1036 cells = 1 organism, different cells for different
functions, exhibit division of labor
C) Diversity of cells
1) Different types of unicellular organisms (Paramecium and Amoeba)
2) Different types of cells in multicellular organisms
(muscle, skeletal, immune, lungs, epithelium, etc...)
D) Classification of cells
1) Two major groups - Prokaryotes and Eukaryotes
2) Differences: Prokaryotes - smaller size, simple structure
(no membrane bound organelles, no nucleus, DNA in a
single strand), primitive (old group of organisms,
nearest relatives of first living organisms)
E) Structural and functional differences between Prokaryotes and Eukaryotes F) Movement across cell membranes
1) Passive transport (no energy)
diffusion 2) Active transport
active transport with ATP
exocytosis and endocytosis
3) Effects of tonicity
According to the current definition of life, the cell is the basic unit of all living things. Unicellular organisms are composed of one cell, and mulitcellular organisms are composed of more than one cell. Examples of unicellular oganisms include prokaryotes such as bacteria and archaea, and protists. Multicellular organisms include plants, animals, and some fungi. Cells vary in size, shape, and function.
Cells are defined as the building blocks of life and hence in both the cases the answer is cell.
every living organism is made up of cells, so cell is the basic building block of living organisms.

Cells are the building blocks of all organisms.
a building block!
Don't you mean: "What is the smallest unit OF an organism and the building block of all life?"? By the way, the answer is a cell.
Phosphate
The "cell".
A cell is building blocks of both unicellular and multicellular organisms. All living things are made up of cells.
it is a cell
carbon
cells.
yes
yan A cell is the unit of life and building block of organisms.
Cells
The common building blocks of simple and complex organisms are called cells. They are the smallest structural unit of an organism.
