Components of a Cell | SPM Biology Form 4/Form 5 Revision Notes
http://spmbiology.onlinetuition.com.my/2013/12/components-of-cell.html
01 Introduction to Physics. 02 Force and Motion. 03 Force and Pressure. Components of a Cell. Each cell consists of a plasma membrane and protoplasm. The protoplasm consist of cytoplasm and nucleus. Cytoplasm contains many types of organelles. The following is the illustration of the animal cell and plant cell. The plasma membrane separates the content of the cell from its external environment. It regulates the movement of substances entering and leaving the cell. It allows substances to move through it.

Unicellular Organism | SPM Biology Form 4/Form 5 Revision Notes
http://spmbiology.onlinetuition.com.my/2013/12/unicellular-organism.html
01 Introduction to Physics. 02 Force and Motion. 03 Force and Pressure. Unicellular organisms are simple organisms consisting of only one cell. Each cell is a complete unit of life that is able to carry out all the living processes. The main groups of unicellular organisms are. Two important unicellular organisms that you need to know in SPM biology are the Amoeba sp. and Paramecium sp. 8212; Share It —. Crafted by VeeThemes.com.

Multicellular Organism | SPM Biology Form 4/Form 5 Revision Notes
http://spmbiology.onlinetuition.com.my/2014/01/multicellular-organism.html
01 Introduction to Physics. 02 Force and Motion. 03 Force and Pressure. Multicellular organisms are organisms that consist of multiple cells (more than one cell). Multicellular organisms are more complex than unicellular organisms and hence need many different types of cell to carry out their life processes. This can be achieved through cell specialisation and cell organisation. Examples of multicellular organisms are hydra, spirogyra, weeds, flowering plants, vertebrate and invertebrate animals.
