1.1: Understand that living Organisms share the following Characteristics:

LETTER	DESCRIPTION
M - MOVEMENT	All Living Organisms Move
R - RESPIRATION	All Living Organisms will Inhale and Exhale
S - SENSITIVITY	All Living Organisms will Respond to Stimuli
G - GROWTH	All Living Organisms will Grow
R - REPRODUCTION	All Living Organisms will Reproduce
E - EXCRETION	All Living Organisms will Excrete Waste
N - NUTRITION	All Living Organisms Require Nutrition

1.2: Describe the common features shared by organisms within the following main groups: Plants, Animals, Fungi, Bacteria, Proctists and Viruses

GROUPS OF ORGANISMS

PLANTS: Multicellular Organisms Stores Carbohydrates as Starch Cells contain Chloroplasts; carries out           Photosynthesis Cell walls are made of Cellulose Example: Herbaceous Legume

ANIMALS Multicellular Organisms Stores Carbohydrates as Glycogen Cells DO NOT contain Chloroplasts; cannot carry out photosynthesis No Cell walls Nervous Coordination: Can move from one place to another Example: Mammals and Insects

FUNGI Both Multicellular and Unicellular Stores Carbohydrates as Glycogen Cell walls are made of Chitin DO NOT carry out Photosynthesis Organised into a Mycelium: Thread-like structure called Hyphae, which contains many Nuclei They feed by Extracellular Secretion: Releases digestive enzymes onto food and absorb organic products ( saprotrophic nutrition ) Example: Mucor / Yeast

BACTERIA Unicellular Organisms Lack in Nuclei’s so has circular chromosomes of DNA called Plasmids Has Cell wall, Cell membrane, Cytoplasm SOME can carry out Photosynthesis Feeds by eating living or dead living Organisms Example: Lactobacillus Bulgaricus (Yoghurt Production)

PROCTISTS Microscopic Unicellular Organisms Example: Animals: Amoeba                            Plants: Chlorella

VIRSUS Small Particles ( smaller than Bacteria ) Parasitic: can only reproduce in living Organisms They only reproduce infect every type of living Organisms They have a wide variety of shapes and sizes No Cellular structure Has protein coat Contains one type of Nucleic Acid ( RNA or DNA ) Example: Tobacco Mosaic Virus / HIV                            Plants: Chlorella

1.3: Recall the term ‘Pathogen’ and know that Pathogens may be Fungi, Bacteria, Protoctists or Viruses

PATHOGENS: Micro-organisms that causes Diseases

COMMON PATHOGENS

FUNGI Both Multicellular and Unicellular Stores Carbohydrates as Glycogen Cell walls are made of Chitin DO NOT carry out Photosynthesis Organised into a Mycelium: Thread-like structure called Hyphae, which contains many Nuclei They feed by Extracellular Secretion: Releases digestive enzymes onto food and absorb organic products ( saprotrophic nutrition ) Example: Mucor / Yeast

BACTERIA Unicellular Organisms Lack in Nuclei’s so has circular chromosomes of DNA called Plasmids Has Cell wall, Cell membrane, Cytoplasm SOME can carry out Photosynthesis Feeds by eating living or dead living Organisms Example: Lactobacillus Bulgaricus (Yoghurt Production)

PROCTISTS Microscopic Unicellular Organisms Example: Animals: Amoeba                            Plants: Chlorella

VIRSUS Small Particles ( smaller than Bacteria ) Parasitic: can only reproduce in living Organisms They only reproduce infect every type of living Organisms They have a wide variety of shapes and sizes No Cellular structure Has protein coat Contains one type of Nucleic Acid ( RNA or DNA ) Example: Tobacco Mosaic Virus / HIV                          Plants: Chlorella
