What are the functions of cell organelles?

Answer 1

Organelles are essentially a chain of machines in the cell to make proteins.

The nucleolus in the nucleus makes RNA components which are coded by the DNA as instructions to make a protein.

The RNA is then sent out of down the Rough ER to program the ribosomes on the Rough ER to make a protein. This Protein gets to the end of the ER, nips off as a Vesicle, and goes into the Golgi apparatus, which packages the protein with other proteins or chemicals to make a more complicated chemical: e.g. haemoglobin.

The protein will then nip off as a vesicle then either stay as a lysosome (bag of enzymes), which is used to digest, destroy, or self destruct things in the cell; or go out of the cell through fusing with the the surface membrane. It can also be used to build other bits of the cell. This whole process is powered by energy from mitochondria, which perform aerobic respiration.

Other organelles not in this process include chloroplasts, which are for photosynthasis; centrioles, which act as bollards for the movement of chromosomes during mitosis and meiosis; the cytoskeleton, which powers this movement and supports the cell, and Smooth ER, which moves and makes lipids (fats).
ribosome - produce proteins

nucleus - controls everything

mitochondria - the "powerhouse" of the cell

cell membrane- controls what goes in or out of the cell

vacuoles - storage are of the cell

anything else let me know

Answer 2

Cell organelles have various functions that contribute to the overall functioning of the cell. For example, the nucleus controls cellular activities and contains genetic material. The mitochondria generate energy through cellular respiration. The endoplasmic reticulum is involved in protein synthesis and lipid metabolism. The Golgi apparatus modifies, packages, and transports proteins. The lysosomes break down wastes and cellular debris. The cell membrane regulates the passage of substances into and out of the cell.
