cell
In biology, the smallest unit that can perform all life processes; cells are covered by a membrane and contain DNA and cytoplasm.
Nucleus
in a eukaryotic cell, a membrane-bound organelle that contains the cell’s DNA and that has a role in processes such as growth, metabolism, and reproduction.
Cell Wall
A rigid structure that surrounds the cell membrane and provides support to the cell.
cell membrane
a phospholipid layer that covers a cell’s surface and act’s as a barrier between the inside of a cell and the cell’s environment.
Organ

Tissue

organism

an organism made up of cells that have a nucleus enclosed by a membrane; eukaryotes includes ,animals, plants and fungi but not archaebacteria or eubacteria.
Golgi complex
cell organelle that helps make and package materials to be transported out of the cell.
Endoplasmic reticulum
a system of membranes that is found in a cell cytoplasm and that assist in the production, processing and transport of proteins.
Vacoule
a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.
a small cavity or space in tissue, especially in nervous tissue as the result of disease.
Chloroplast
(in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place.
