• Nucleus: The nucleus maintains the genes and controls the functions of the cell in its entirety by regulating gene expression. It is referred to as the control center, or the "brain," of the cell.
• Nuclear envelope: (also referred to as the nuclear membrane) is the membrane that encloses the nucleus and encases genetic material.
• Nuclear pores: are protein-based channels in the nuclear envelope. They regulate the movement of molecules from the nucleus to the cytoplasm, and vice versa.
• Nucleolus: the nucleolus could loosely be thought of as the brain of the nucleus. Its main function is to rewrite ribosomal RNA (rRNA) and combine it with proteins.
• Cell membrane: is like a filter, it's function is to protect the integrity of the interior of the cell by allowing certain substances into the cell, while keeping other substances out.
• Cell wall: the cell wall gives the plant its actual shape. It acts as a gatekeeper, because it determines what can come in and out of the cell in order to keep the cell protected.
• Mitochondria: the main job of mitochondria is to perform cellular respiration. It takes in nutrients from the cell, breaks it down, and turns it into energy. This energy is then used by the cell for various functions.

• Lysosomes: these organelles act as a garbage disposal because they break down biomolecules like lipids and carbohydrates and digest unwanted materials within the cytoplasm of the cell.
• Ribosomes: ribosomes are a cell structure that produces protein. Protein is needed for many cell functions such as repairing damage or directing chemical processes.
• Golgi apparatus: The job of the Golgi apparatus is to process and bundle macromolecules like proteins and lipids as they are synthesized within the cell.
• Vacuole: typically, their job includes isolating harmful materials, storing waste products, storing valuable water in a plant cell, and helping maintain the pressure within a cell.
• Endoplasmic reticulum: endoplasmic reticulum has a number of jobs within the cell. This includes the folding and transportation of various proteins, specifically carrying them to the Golgi apparatus.
• Centriole: The main function of the centriole is to help with cell division in animal cells. The centrioles help in the formation of the spindle fibers that separate the chromosomes during cell division (mitosis).
• Cytoplasm: responsible for giving a cell its shape. It helps to fill out the cell and keeps organelles in their place. Without cytoplasm, the cell would be deflated and materials would not be able to pass easily from one organelle to another.
