Card 1: Unicellular and Multicellular Organism

Unicellular and Multicellular Organism

Unicellular Organism - Organism with just 1 cell
Multicellular Organism - Organism made up of more than 1 cell.
Card 2: Give 4 examples of unicellular organism.

Examples of unicellular organism

  1. Paramecium
  2. Amoeba
  3. Yeast
  4. Chlamydomanas
Card 3: State the 8 basic living processes of an organism.

Living Processes of Organism

  1. Feeding
  2. Locomotion
  3. Reproduction
  4. Respiration
  5. Growth
  6. Excretion
  7. Response to stimuli
  8. Heredity
Card 4: What is cell specialisation?

Cell specialisation

Cell specialsation means division of labour among cells. Each type of cell specialises in a specific funtion.

Card 5: State the importance of cell specialisation in multicelluar organism.

Importance of Cell Specialisation

  1. Cells can perform specific task with greater efficiency.
  2. Enable multicellular organisms adapt to various environment.
Card 6: Give some examples of cell specialisation in animal.

Cell Specialisation in Animal

Cell Function
Red blood cells Transprot oxygen
White blood cells Destroy microorganisms. Engulf foreign substance in the blood stream.
Smooth muscle cells Contract and release to produce movement
Nerve cells Transmits nerve impulse
Card 7: Give some examples of cell specialisation in plant.

Cell Specialisation in Plant

Cell Function
Palisade Mesophyll Cells Carries out photosynthesis
Guard Cells Control the size of the stomata pore to allow gaseous exchange.
Xilem Transport water and mineral salt
Phloem Transport disolved food.
Card 8: List down how cells are organised in a multicellular organism.

Card 9: What is cytology?

Cytology (Cell Biology)

Cytology is an academic discipline that studies cells. It's also known as Cell Biology.

Card 10: What is histology?

Histology

histology is the study of the microscopic anatomy of cells and tissues of plants and animals.
