Ribosomes are a cell structure that makes protein. Protein is needed for many cell functions such as repairing damage or directing chemical processes. Ribosomes can be found floating within the cytoplasm or attached to the endoplasmic reticulum.
In addition to a cell wall, plant cells also have this very large structure that can take up as much as 80% of the cell's volume. This is called a central vacuole, a large storage compartment in plant cells. What can this vacuole hold? Well, although other non-plant cells can also have vacuoles, plant cells have these characteristically gigantic vacuoles that are largely a storage place for water. While animal cells are around 70% water, plant cells can be 90% full of water - and they need a place to put it! However, in addition to water, a vacuole can also contain food and other nutrients, as well as waste products.
The central vacuole can also contain digestive enzymes like those in animal cell lysosomes. A central vacuole also can help maintain a neutral pH in the cell by pumping hydrogen atoms, or protons, from the cytoplasm into the vacuole. What happens if you pump a lot of protons into the vacuole? This makes this plant cell component acidic, which also is similar to a lysosome.
jellylike material that makes up much of a cell inside the cell membrane, and, in eukaryotic cells, surrounds the nucleus... you want to measure that???? you need a micro scope for starters let me know when you get that far....
Transcription and translation are spatially and temporally separated in eukaryotic cells; that is, transcription occurs in the nucleus to produce a pre-mRNA molecule. The pre-mRNA is typically processed to produce the mature mRNA, which exits the nucleus and is translated in the cytoplasm.
An animal cell is a type of eukaryotic cell that dominates most of the tissue cells in animals.Animal cells are different from plant cells because they lack cell walls and chloroplasts, which are pertinent to plant cells.
