What is a Cell?
The cell (from Latin cella, meaning "small room") is the basic structural, functional, and biological unit of all known living organisms. A cell is the smallest unit of life. ... Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids.
What parts do all cells have in common?
Although cells are diverse, all cells have certain parts in common. The parts include a plasma membrane, cytoplasm, ribosomes, and DNA. The plasma membrane (also called the cell membrane) is a thin coat of lipids that surrounds a cell.
What is the difference between Prokaryotic Cell and Eukaryotic Cell?

What is a Eukaryotic Cell?
Eukaryotic cells are cells that contain a nucleus and organelles, and are enclosed by a plasma membrane. Organisms that have eukaryotic cells include protozoa, fungi, plants and animals. These organisms are grouped into the biological domain Eukaryota. Eukaryotic cells are larger and more complex than prokaryotic cells, which are found in Archaea and Bacteria, the other two domains of life.
What is a Prokaryotic Cell?
Components of prokaryotic cells
There are some key ingredients that a cell needs in order to be a cell, regardless of whether it is prokaryotic or eukaryotic. All cells share four key components:
Despite these similarities, prokaryotes and eukaryotes differ in a number of important ways. A prokaryote is a simple, single-celled organism that lacks a nucleus and membrane-bound organelles. We’ll talk more about the nucleus and organelles in the next article on eukaryotic cells, but the main thing to keep in mind for now is that prokaryotic cells are not divided up on the inside by membrane walls, but consist instead of a single open space.
The majority of prokaryotic \text{DNA}DNAD, N, A is found in a central region of the cell called the nucleoid, and it typically consists of a single large loop called a circular chromosome. The nucleoid and some other frequently seen features of prokaryotes are shown in the diagram below of a cut-away of a rod-shaped bacterium.
There are some key ingredients that a cell needs in order to be a cell, regardless of whether it is prokaryotic or eukaryotic. All cells share four key components:
- The plasma membrane is an outer covering that separates the cell’s interior from its surrounding environment.
- Cytoplasm consists of the jelly-like cytosol inside the cell, plus the cellular structures suspended in it. In eukaryotes, cytoplasm specifically means the region outside the nucleus but inside the plasma membrane.
- DNA is the genetic material of the cell.
- Ribosomes are molecular machines that synthesize proteins.

Connection diagram between Cellular Respiration and Photosynthesis
1.We started by going out and collecting dead plant parts.
2.We stuck the plant parts on the construction sheet that teacher gave us.
3.Then we made molecules from clay, and stuck it on the construction sheet too.
4.We then made a mitochondria out of clay, and we also stuck it on the construction sheet
5.Then, We wrote our names and details about our project with whitener
6. Finally, We decorated it with decoration tape
