Cell Membrane-
the semipermeable membrane surrounding the cytoplasm of a cell.
Lysosome-
an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane.
Golgi Bodies
a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.
Mitochondria-
an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae).
Selective Permeability-
cell membrane is one that allows certain molecules or ions to pass through it by means of active or passive transport.
Plants are eukaryotes, multicellular organisms that have membrane-bound organelles. Unlike prokaryotic cells, eukaryotic cells have a membrane-bound nucleus. A plant cell is different from other eukaryotic cells in that it has a rigid cell wall, a central vacuole, plasmodesmata, and plastids.

Animal cells are typical of the eukaryotic cell, enclosed by a plasma membrane and containing a membrane-bound nucleus and organelles. Unlike the cells of the two other eukaryotic kingdoms, plants and fungi, animal cells don't have a cell wall.
Prokaryotes lack a distinct cell nucleus and their DNA is not organized into chromosomes. They also lack the internal structures bound by membranes called organelles, such as mitochondria.
Eukaryotes a cell with a true nucleus; a cell with a nuclear membrane and organelles;
SIMILARITIES:
1. They both have DNA as their genetic material.
2. They are both membrane bound.
3. They both have ribosomes .
4. They have similar basic metabolism .
5. They are both amazingly diverse in forms.
DIFERENCES:
1. eukaryotes have a nucleus, while prokaryotes do not
2. eukaryotes have membrane-bound organelles, while prokaryotes do not. The organelles of eukaryotes allow them to exhibit much higher levels of intracellular division of labor than is possible in prokaryotic cells.
3. Eukaryotic cells are, on average, ten times the size of prokaryotic cells.
4. The DNA of eukaryotes is much more complex and therefore much more extnsive than the DNA of prokaryotes.
5. Prokaryotes have a cell wall composed of peptidoglycan, a single large polymer of amino acids and sugar . Many types of eukaryotic cells also have cell walls, but none made of peptidoglycan.
6. The DNA of prokaryotes floats freely around the cell; the DNA of eukaryotes is held within its nucleus and associated with histones (proteins)
7. Eukaryotes undergo mitosis; prokaryotes divide by binary fission (simple cell division)
Enzymes-
a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction.
