Basic Anatomical Terminology

Cellular level of

Organization

Structure

Of Cell

The detailed structure of a cell has

been studied under compound

microscope and electron microscope.

Certain structures can be seen only

under an electron microscope.

The structure of a cell as seen under

an electron microscope is called

ultrastructure.

Compound

microscope

Magnification 2000X

Plasma Membrane

Carbohydrates

Proteins

  • Extremely delicate, thin , elastic, living

and semi-permeable membrane

  • Made up of two layers of lipid molecules

in which protein molecules are floating

  • Thickness varies from 75-110 A˚
  • Can be observed under an electron

microscope only

Functions:

  • Maintains shape & size of the cell
  • Protects internal contents of the cell
  • Regulates entry and exit of substances

in and out of the cell

Lipids

  • Maintains homeostasis

Cell wall • Non-living and outermost covering of a cell

(plants & bacteria)

Pectin

Plasma membrane

Cellulose

Hemicellulose

  • Can be tough, rigid and sometimes flexible
    • Made up of cellulose, hemicellulose and

pectin

  • May be thin or thick, multilayered structure
    • Thickness varies from 50-1000 A˚

Functions:

  • Provides definite shape, strength & rigidity
    • Prevents drying up(desiccation) of cells
      • Helps in controlling cell expansion
  • Protects cell from external pathogens

Nucleus

  • Nucleus has a double layered covering called

Nuclear

pores

Nuclear

envelope

Nucleolus

Chromatin

Nucleoplasm

nuclear membrane

  • Nuclear membrane has pores of diameter

about 80-100 nm

  • Colourless dense sap present inside the

nucleus known as nucleoplasm

  • Nucleoplasm contains round shaped

nucleolus and network of chromatin fibres

  • Fibres are composed of deoxyribonucleic

acid (DNA) and protein histone

  • These fibres condense to form chromosomes

during cell division

Nucleus

Gene

Histone

Chromatin fibre

Chromosome

DNA

Chromatin

  • Chromosomes contain stretches of DNA

called genes

  • Genes transfer the hereditary information

from one generation to the next

Functions:

  • Control all the cell activities like metabolism,

protein synthesis, growth and cell division

  • Nucleolus synthesizes ribonucleic acid (RNA)

to constitute ribosomes

  • Store hereditary information in genes

Endoplasmic

Reticulum

Rough ER

Smooth ER

Ribosomes

  • Network of tubular and vesicular structures

which are interconnected with one another

  • Some parts are connected to the nuclear

membrane, while others are connected to

the cell membrane

  • Two types: smooth(lacks ribosomes) and

rough(studded with ribosomes)

Functions:

  • Gives internal support to the cytoplasm
  • RER synthesize secretory proteins and

membrane proteins

  • SER synthesize lipids for cell membrane
  • In liver cells SER detoxify drugs & poisons
  • In muscle cells SER store calcium ions

Golgi body

Incoming

transport

  • Discovered by Camillo Golgi
  • Formed by stacks of 5-8 membranous sacs
  • Sacs are usually flattened and are called

the cisternae Cis face

Cisternae

Newly Trans face

forming

vesicle

vesicle

Lumen

Outgoing

transport

vesicle

  • Has two ends: cis face situated near the

endoplasmic reticulum and trans face

situated near the cell

membrane

Functions:

  • Modifies, sorts and packs materials

synthesized in the cell

  • Delivers synthesized materials to various

targets inside the cell and outside the cell

  • Produces vacuoles and secretory vesicles
    • Forms plasma membrane and lysosomes
