I have come across this website about overview of two different plant Cells namely . The article gives me a holistic view of the Plant Cell.

Two types of different Plant Cells.

The eukaryotic cell is composed of 4 main parts:

cell membrane - outer boundary of the cell
cytoplasm - jelly-like fluid interior of the cell
nucleus - the "control center" of the cell, contains the cell's DNA (chromosomes)
organelles - "little organs" that carry out cell functions





Prokaryotes are very simple cells, probably first to inhabit the earth.
Prokaryotic cells do not contain a membrane bound nucleus.
Bacteria are prokaryotes.
DNA of bacteria is circular.

The word "prokaryote" means "before the nucleus"
