Answer:
cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. ... All living organisms are composed of one or more cells.

ANSWER.
Cell theory
In biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. ... All living organisms are composed of one or more cells.
the 3 points of cell theory
These findings led to the formation of the modern cell theory, which has three main additions: first, that DNA is passed between cells during cell division; second, that the cells of all organisms within a similar species are msotly the same, both structurally and chemically; and finally, that energy flow occurs
the 6 components of the cell theory
#1. Cells are the basic unit of life.
#2. Cells have hereditary data that is passed down to their offspring.
#3. All cells come from preexisting cells.
#4. All organisms, both unicellular and multicellular, are made of one or more cells.
#5. Energy flows through cells.
#6. All cells have a similar composition.
The Origins Of The Word 'Cell' In the 1660s, Robert Hooke looked through a primitive microscope at a thinly cut piece of cork. He saw a series of walled boxes that reminded him of the tiny rooms, or cellula, occupied by monks. Medical historian Dr. Howard Markel discusses Hooke's coining of the word "cell.
the main points of cell theory
Cell theory states that living things are composed of one or more cells, that the cell is the basic unit of life, and that cells arise from existing cells.
the two types of cells
Cell types. Cells are of two types: eukaryotic, which contain a nucleus, and prokaryotic, which do not. Prokaryotes are single-celled organisms, while eukaryotes can be either single-celled or multicellular
Major Functions of a Cell
Energy Generation-Living cells exist in a perpetually active biological state.
Molecular Transport- Each cell is surrounded by a membrane that delineates its boundaries and acts as a gatekeeper, controlling the movement of molecules into and out of the cell
6 Cell Organelles
Nucleus-nucleus; animal cell
Ribosomes- Ribosomes are the protein factories of the cell.
Endoplasmic reticulum-Ribosomes on the outer surface of the endoplasmic reticulum play an important role in protein synthesis within cells
Golgi apparatus
Chloroplasts
Mitochondria
