Organelles are components of a cell to which a function or role can be assigned. Depending on whether the cell is prokaryotic or eukaryotic, the organelle may be different.
Functions of different cell organelles:
- Nucleus: contains all the genetic material, acts as information center and tells all the organelles what to do, RNA transcription.
- Mitochondria: generates energy through respiration
- Endoplasmic recticulum (rough): transport and storage of material; (smooth ER): creation of lipids and fats
- Ribosome: protein creation by RNA translation
- Golgi apparatus: responsible for synthesis, packing and processing of proteins
- Chloroplast: responsible for glucose creation (by photosynthesis)
- Cytoplasm: is region where all chemical reactions take place
- lysosome: responsible for breakdown of larger molecules
- Flagellum (or flagella): tail like organelle, assists motion
- Vacuole: helps in maintenance of homeostasis
- cell membrane: separates cell from the rest of the environment
- cytoskeleton: supports cell structure
There are a number of other organelles as well.
