Cells are in every living thing.

Types of Cells

These are just some types of cells but there are many more.

Cell Membrane

the cell membrane is the semipermeable membrane surrounding the cytoplasm of a cell

Cell Wall

a rigid layer laying outside the plasma membrane to the cells of plants, fungi, and bacteria


the material within a living cell excluding the nucleus.


the center of a cell.

Nuclear Membrane

A nuclear membrane, also known as the nuclear envelope, nucleolemma or karyotheca, is the double lipid bilayer membrane which surrounds the genetic material and nucleolus in eukaryotic cells.


  1. a small dense spherical structure in the nucleus of a cell during interphase.


  1. a minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.


  1. the material of which the chromosomes of organisms other than bacteria (i.e., eukaryotes) are composed. It consists of protein, RNA, and DNA.


  1. a minute particle consisting of RNA and associated proteins, found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins.

Golgi apparatus

  1. a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.

Endoplasmic reticulum

  1. a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually has ribosomes attached and is involved in protein and lipid synthesis.


  1. an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae).


  1. (in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place.


  1. an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane.


  1. a small organelle that is present in the cytoplasm of many cells and that contains the reducing enzyme catalase and usually some oxidases.


a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.


  1. a microscopic network of protein filaments and tubules in the cytoplasm of many living cells, giving them shape and coherence.
