Cell Membrane: Semi-permeable layer which controls what enters and exits the cell.

Cell Wall: (are not present in animal cells) Is for structural support for the cell

Nucleus: Controls activities and regulates the cell, known as the control center of a cell

Nuclear Membrane/Nuclear Envelope: Double membrane layer that is mainly for separation of the contents present in the nucleus from the outside.

Ribosome: Forms protein from amino acids sent through the cell

ER: Protein synthesis and protein transport

Mitochondria: Powerhouses of cells, responsible for cellular respiration and producing energy in the form of ATP

Chloroplasts (not present in animal cells): Mainly for the process of photosynthesis

Golgi Apparatus: Lysosome support, transports proteins and lipids through vesicles

Vacuole : Balances pH (stores water for structural support as well)

Lysosomes: Breaks down waste, helps the cell's metabolism

This took a while, sorry for the wait, I really hope this helps!
