what are the 3 main parts of a cell?

1. plasma membrane

2. cytoplasm

3. nucleus

plasma membrane

The plasma membrane forms the cell's flexible outer surface, separating the cell's internal environment (everything inside the cell) from the external environment (everything outside the cell). It is a selective barrier that regulates the flow of materials into and out of a cell. This selectivity helps establish and maintain the appropriate environment for normal cellular activities. The plasma membrane also plays a key role in communication among cells and between cells and their external environment

cytoplasm

The cytoplasm (-plasm = formed or molded) consists of all the cellular contents between the plasma membrane and the nucleus. This compartment has two components: cytosol and organelles. Cytosol, the fluid portion of cytoplasm, also called intracellular fluid, contains water, dissolved solutes, and suspended particles. Within the cytosol are several different types of organelles (= little organs). Each type of organelle has a characteristic shape and specific functions. Examples include the cytoskeleton, ribosomes, endoplasmic reticulum, Golgi complex, lysosomes, peroxisomes, and mitochondria

nucleus

The nucleus (= nut kernel) is a large organelle that houses most of a cell's DNA. Within the nucleus, each chromosome (chromo- = colored), a single molecule of DNA associated with several proteins, contains thousands of hereditary units called genes that control most aspects of cellular structure and function
