Differences of Plant Cell and Animal Cell

             Animal Cell                                        Plant Cell

Absence of cellulose cell wall              Presence of cellulose cell wall
Absence of chloroplast                         Presence of chloroplast
Numerous small vacuoles                    A large central vacuole
Cytoplasm fills the cell                        Cytoplasm reduced to a thin lining
Absence of starch grains                      Presence of starch grains           
Presence of a pair of centrioles            Absence of a pair centrioles

             

        

        

Basic info on orgnanelles

• Both animal and plant cells contain organelles
- an organelle is a structure in the cytoplasm in the cell
- all organelles have a membrane [except free ribosome] surrounding it

Some diagrams...

Info on plant cell organelles

Smooth Endoplasmic Reticulum [ER] - removes toxic from body
Rough ER - produces protein
Ribosome - produce protein
Mitochondrion - converts glucose into molecules of energy [ATP - Adenosine Triphosphate]
Nucleus - controls most of the activities
Nuclear membrane - a membrane surrounding the nucleus
Chromosomes - found in the nucleus. Contain DNAs [a chemical that determines what traits an organism will have]
Vacuole - stores food, water, minerals and wastes
Cytoplasm - geltatinelle substance that contains many chemical that the cell needs for chemical reactions
Cell/plasma membrane - controls what enters and leaves the cell
Centrioles - used for cell division
Cell wall - provides supportand protection
Chloroplast - captures energy from sun light and uses it to convert carbon dioxide into food
Plasmodesmata - serves as a specialised cell to cell communication junction
Cell sap - liquid that contains dissolved substances[eg. sugar & salt] and keeps cells firm by taking in water

About Cells :D

The Cell
• It is the smallest unit of a living thing
• Unicellular - eg. bacteria, paramecium
• Multicellular - eg. frog, human
• Unicellular organisms perform all functions in a cell
• Multicellular organisms require cell specialisation

Cell Theory
• All living things are composed of cells
• Cells are the most basic unit for function and structure of all organisms
• Cells come from other cells with cells passing copies of their genetic material [DNA] onto their daughter cells
