i dont have everything. but i got a few for u.
functions of organelles:
the cell membrane:
- cell-cell recognition
- separate cyctoplasm from outside enviroment
- absorbtion of ions
- maintain different conc of ions in and out of the cell by diffusion, facilitated diffusion, osmosis, endocytosis and active transport.
- prevent viruses and bacteria from entering cell
- enables phagocytosis (cell "eating") and pinocytosis (cell "drinking")
- allows disposal of waste material (when secretory vesicles fuse with membrane to secrete material)
- attaches cell to other cells through desosomes, gap junctions, and tight junctions
- Increase surface area for exchange of substances using microvilli
golgi body or golgi apparatus:
- receives protiens from endoplasmic reticulum at the 'cis' face
- packages and modifies proteins for export froom the 'trans' face
- synthesis of secretory polysaccharides
- formation of lysosomes
- addition of material to cell membrane (enlargement)
Lysosomes:
- digestion of ingested particles (taken in by endocytosis)
- disposal of defunct or surplus organelles (autophagy)
- cell death (autolysis)
Endoplasmic Reticulum:
- provide large surface area for chemical reactions
- form intracellular transport system
- post-translational modifications of proteins synthesised at the ribosomes
- synthesis of lipids and steroids
- detoxication
- storage and release of calcium ions
Mitochondria
- synthesis of ATP (Adenosine triphosphate)
- Heat production (55% of energy released from the reactions in the mitochondria is given off as heat)

B. transportation in and out of the nucleus. responsible for steroid and hormone production
C. contains ribosomes for protein production and transportation
D. packages and labels products for shipment throughout the cell (like a post office)
E. aids in mitosis in animal cells
F. cleans up the cell. digests waste within the cell. can signal for apoptosis (cell suicide/programmed cell death)

In a house, you could have it like this: nucleus - living room Mitochondria - kitchen Ribosome - pantry Vacuole - attic or basement Golgi apparatus - office lysosome - a garbage can smooth ER - dining room

your in 7th grade, right?
i learned that last year
arn't the definitions in your science book?
you can also try in the dictionary
