Cell membrane | Controls the movement of substances in and out of cells. The basic function of the cell membrane is to protect the cell from its surroundings. |
Nucleus | An organelle found in eukaryotic cells. Inside its fully-enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes. |
Vacuole | Often the largest organelle in the cell. It is surrounded by a membrane and functions to hold materials and wastes. It also functions to maintain the proper pressure within the plant cells to provide structure and support for the growing plant. |
Golgi body | The Golgi apparatus is an organelle present in most eukaryotic cells. It is made up of membrane-bound sacs. The job of the Golgi apparatus is to process and bundle macromolecules like proteins and lipids as they are synthesized within the cell. |
Cytoplasm | The jelly-like fluid that fills a cell is called cytoplasm. It is made up of mostly water and salt. Cytoplasm is present within the cell membrane of all cell types and contains all organelles and cell parts. |
Lysosome | Inside a cell, numerous organelles function to remove wastes. One of the key organelles involved in digestion and waste removal is the lysosome. Lysosomes are organelles that contain digestive enzymes. They digest excess or worn out organelles, food parti |
Endoplasmic Reticulum | The endoplasmic reticulum serves many general functions, including the folding of protein molecules in sacs called cisternae and the transport of synthesized proteins in vesicles to the Golgi apparatus. |
