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 and is the jelly like fluid that holds all the organelles in place inside of the cell
lysosome: responsible for breakdown of larger molecules
Flagellum (or flagella): tail like organelle, assists motion
Vacuole: helps in maintenance of homeostasis and stores waste products or other materials like water / food
cell membrane: separates cell from the rest of the environment and controls what comes in and out of the cell
cytoskeleton: supports cell structure
