The cell: ideas about cell structure have change considerable over the years. Early biologists saw cells as simple membranous sacs containing fluids  and a few floating particles. today’s biologists know that cells are infinitely more complex than this.

there are many different types, size and shapes of cells in the body. For descriptive purpose the concept of a generalized cell is introduced it includes features from cell types. A cell consists of three parts: the cell membrane the nucleus and between the two, the cytoplasm. Within the cytoplasm lie intricate arrangement of five fiber and hundred or even thousand of minuscule but district structures called organelles

 

TYPES: CELL MEMBRANE

Every cell in the body is enclosed by a cell by a cell (plasma) membrane. the cell membrane separates the material outside the cell extracellular from the materia into and out of the cell all material within a cell must have access to the cell membrane (the cells boundary) for the needed exchange.

NUCLEUS AND NUCLEOLUS

 

The nucleus formed by a nuclear membrane around a fluid nucleoplasm is the is the control center of the cell. Treads of chromatin in the nucleus contain deoxyribonucleic acid (DNA) the genetics material of the cell. The nucleolus is a dense region of the site of ribosomes formation. The nucleus determines how the cell will function as well as the basics structure of that cells

CYTOPLASM

cytoplasm is the gel like fluid inside the cell. It is the medium for chemical reaction it provides a platform upon which other organelles can operate within the cell

CYTOPLASMIC ORGANELLES

Cytoplasmic organelles are little organs that are suspended in the cytoplasm of the cell. Each types of organelles has a definite structure and a specific role in the function of the cell examples of cytoplasmic organelles are mitochondrion, ribosomes endoplasmic reticulum , golgi apparatus and lysosomes.

EXPECTATION

The cell structure is defined by the cell membrane the cytoplasm and the nucleus. A cell is the smallest unit of life and its structure helps it to work as the basics building block biology.
