Cells are generally divided into two types of cells. Eukaryotic (generally mulitcellular organisms like humans and palm trees) and Prokaryotic (generally single celled organisms, like bacteria). All Eukaryotic cells will be a little more complicated, having membrane-bound organelles (these are your cells "organs" such as the mitochondria, Golgi apparatus, and endoplasmic reticulm, just for starters) and a defined nucleus. All Eukaryotic cells have a defined nucleus.
Prokaryotic cells, however are a different story. Prokaryotic cells are very simple and contain no membrane-bound organelles-- not even a nucleus! Instead the DNA floats freely in an area of the cell known as the nucleoid region.
The two things that both Eukarotes and Prokaryotes have in common are:
1) Both have a semi-permeable plasma membrane
2) Both have ribosomes, though the structure of the ribosomes is very different (interestingly enough, bactieral ribosomes are found int he mitochondrian of Eukaryotic cells-- but that's another story...)
* All cells also have cytoplasm which is also considered an organelle
Centrioles and lysosomes cannot be found in plant cells.
The largest, and most easily visible organelle found in MOST cells is the nucleus. It is large and dark staining, and quickly seen in a microscope. However, only eukaryotic cells have a nucleus. Prokaryotic cells don't have organelles at all.
A large, double membrane-bound organelle found in eukaryotic cells. Contains DNA and RNA. Organelle - A membrane-bound sub-cellular structure found in eukaryotic cells. The Cell nucleus, mitochondria, ER, and golgi apparatus are all examples.
mitochondria
An example of an organelle is mitochondria, a vacuole, or chloroplast, which is only found in plant cells.
Mitochondria
cytoplasm is found in cells. it the watery fluid in which all the organelle's are present
cell membrane
Centrioles and lysosomes cannot be found in plant cells.
Chlorophyll is the only organelle that exists in plant cells and not animal cells.
chloroplasts
yes
Organelles are found in cells
Chloroplasts
any organelle
The largest, and most easily visible organelle found in MOST cells is the nucleus. It is large and dark staining, and quickly seen in a microscope. However, only eukaryotic cells have a nucleus. Prokaryotic cells don't have organelles at all.
