Cell component: Cells are composed of water, inorganic ions, and carbon-containing (organic) molecules. Water is the most abundant molecule in cells, accounting for 70% or more of total cell mass. Consequently, the interactions between water and the other constituents of cells are of central importance in biological chemistry.

Cell organelles : there are thirteen parts of an animal and human cell which are :  vacuoles for Store water and nutrients, cytoplasm Contains the contents of the cell, vesicles for Transport materials around the cell, centrioles for organizing microtubules that serve as the cell's skeletal system, ribosomes: Makes protein, nuclear membrane: protect uncles , cell membrane: protect cell, cytoskeleton: support and transport , mitochondria: give energy , endoplasmic reticulum: protein formation , nucleolus, Golgi apparatus protein transport  and nucleus.
