|
Prokaryote |
are organisms without a cell nucleus, or any other membrane-bound organelles. Most are unicellular, but some prokaryotes are multicellular.
|
|
|
Eukaryote
|
organisms whose cells are organized into complex structures by internal membranes and a cytoskeleton. The most characteristic membrane bound structure is the nucleus.

|
|
Prokaryotic Plasma Membrane
|
responsible for controlling what gets into and out of the cell
|
|
|
Prokaryotic Cytoplasm
|
gel-like, yet fluid, substance in which all of the other cellular components are suspended
|
|
|
Prokaryotic Ribosomes
|
build proteins by translating messages sent from DNA.
|
|
|
Capsule
|
Found in some bacterial cells, this additional outer covering protects the cell when it is engulfed by other organisms, assists in retaining moisture, and helps the cell adhere to surfaces and nutrients.
|
|
|
Cell Wall
|
outer covering that protects the bacterial cell and gives it shape.
|
|
|
Pili
|
Hair-like structures on the surface of the cell that attach to other bacterial cells. Shorter pili called fimbriae help bacteria attach to surfaces.
|
|
|
Flagella
|
long, whip-like protrusion that aids in cellular locomotion
|
|
|
Plasmids
|
gene carrying, circular DNA structures that are not involved in reproduction.
|
|
|
Nucleiod Region
|
Area of the cytoplasm that contains the single bacterial DNA molecule
|
|
|
Eukaryotic Cell Structure |
17 chromatin |
|
|
Cell membrane
|
-It is a semi-permeable barrier, allowing only a few molecules to move across it.
-Electron microscopic studies of cell membrane shows the lipid bi-layer model of the plasma membrane, it also known as the fluid mosaic model. -The cell membrane is made up of phospholipids which has polar(hydrophillic) heads and non-polar (hydrophobic) tails. |

|
|
Chloroplast
|
plastid with green pigment chlorophyll. It traps light energy and converts it to chemical energy by the process of photosynthesis.
|
|
|
Plastids
|
storage organelles. They store products like starch for synthesis of fatty acids and terpenes
|
|
|
Leucoplast
|
They are a type of plastid which are non-pigmented.
|
|
|
Chromoplast
|
They are plastids responsible for pigment synthesis and storage. They are found in photosynthetic eukaryotic species. They are found in colored organs of plants like fruits and flowers
