A+ A A-

In this unit, students will be covering the basic unit of life and know that all living organisms are made of cells. Students will also learn to draw, label and identify the difference between plant and animal cells. This topic will also cover the functions of the important organelles like the nucleus, cell membrane, mitochondria, chloroplast and vacuole. Students will also be expected to describe the appropriate method how substances leave and enter a cell membrane. The methods are diffusion and osmosis. Experiments will be done to allow students to understand the concepts better.

Learning Targets

List and describe the characteristics of living organisms

Define the terms:

  • nutrition as taking in of nutrients which are organic substances and mineral ions, containing raw materials or energy for growth and tissue repair, absorbing and assimilating them


Discuss about the unity of all living organisms (processes, genetic material, etc.) and think about how it affects being a Global Citizen of this world.

  • excretion as removal from organisms of toxic materials, the waste products of metabolism (chemical reactions in cells including respiration) and substances in excess of requirements
  • respiration as the chemical reactions that break down nutrient molecules in living cells to release energy
  • sensitivity as the ability to detect or sense changes in the environment (stimuli) and to make responses
  • reproduction as the processes that make more of the same kind of organism
  • growth as a permanent increase in size and dry mass by an increase in cell number or cell size or both • movement as an action by an organism or part of an organism causing a change of position or place
