1.1: Understand that living Organisms share the following Characteristics:

LETTER	DESCRIPTION
MOVEMENT	All living organisms move
RESPIRATION	All living organisms respire
SENSITIVITY	All living organisms respond to their environment
GROWTH	All living organisms grow and develop
REPRODUCTION	All living organisms reproduce
EXCRETION	All living organisms excrete waste
NUTRITION	All living organisms require nutrition
CONTROL	All living organisms control internal conditions

1.2: Describe the Common Features shared by Organisms: Plants, Animals, Fungi and Protoctists

GROUPS OF ORGANISMS
PLANTS s Multicellular organism Stores carbohydrates as Starch Structure:  Nucleus - membrane-bound organelle containing chromosomes Chloroplast - protein to carry out Photosynthesis  Mitochondria - protein to carry out cell respiration  Cytoplasm - fills the cell to facilitate chemical reactions and holds organelles in place Vacuole - storage organelle for Water and dissolved substances  Cell membrane - phospholipid bilayer that controls movement of substances into and out of cell Cell wall - made of Cellulose to protect and maintain the shape of cell  Example: Herbaceous Legume
ANIMALS s Multicellular organism Stores carbohydrates as Glycogen Has nervous coordination to move from one place to another Structure: Nucleus - membrane-bound organelle containing chromosomes Mitochondria - protein to carry out cell respiration  Cytoplasm - fills the cell to facilitate chemical reactions and holds organelles in place Cell membrane - phospholipid bilayer that controls movement of substances into and out of cell s Example: Mammals, Insects
FUNGI s Both multicellular and unicellular Stores carbohydrates as Glycogen Organised into a Mycelium - thread-like structure called Hyphae that contains many Nuclei Feeds by extracellular secretion - the release of digestive enzymes onto food to absorb organic products (saprotrophic nutrition) Structure: Nucleus - membrane-bound organelle containing chromosomes Mitochondria - protein to carry out cell respiration  Cytoplasm - fills the cell to facilitate chemical reactions and holds organelles in place Cell membrane - phospholipid bilayer that controls movement of substances into and out of cell Example: Mucor / Yeast
PROTISTS s Microscopic unicellular organism Structure of protists are varied Example: Amoeba (animals) Chlorella (plants)

1.4: Understand the Term Pathogen and Know that Pathogens May Include Fungi, Bacteria, Protoctists or Viruses

COMMON PATHOGENS
FUNGI s Both multicellular and unicellular Stores carbohydrates as Glycogen Organised into a Mycelium - threat-like structure called Hyphae that contains many Nuclei Feeds by extracellular secretion - the release of digestive enzymes onto food to absorb organic products (saprotrophic nutrition) Structure: Nucleus - membrane-bound organelle containing chromosomes Mitochondria - protein to carry out cell respiration  Cytoplasm - fills the cell to facilitate chemical reactions and holds organelles in place Cell membrane - phospholipid bilayer that controls movement of substances into and out of cell Example: Mucor / Yeast
BACTERIA s Unicellular organism Feeds on living or dead organisms Structure: Nucleoid - single circular strand of DNA Plasmid - independent small circle of DNA Plasma membrane - phospholipid bilayer that controls movement of substances into and out of cell  Cell wall - made of Peptidoglycan to protect and maintain shape of cell   *Pili - protein filmanets that facilitates cell adhesion and conjugation   *70S Ribosomes - site of protein synthesis   *Flagellum - elongated inflexible structure that rotates to move cell Example: Lactobacillus Bulgarcius (rod-shaped bacterium used in production of Yoghurt) Pnemococcus (spherical bacterium that causes Pneumonia)
PROTISTS s Microscopic unicellular organism Structure of protists are varied Example: Amoeba (animals) Chlorella (plants)
VIRUS s Non-living organism Parasitic as they can only reproduce inside living host cells Structure: Capsid - contains genetic material (DNA or RNA) Viral Envelope - made from fatty lipid molecules taken from host cells to avoid host immune system Surface Protein - proteins that help recognise and bind to host cells for infection Example: Tobacco Mosaic Virus (plant virus that causes discolouration of the leaves of tobacco plants) HIV (human virus that causes AIDS)

1.3: Describe the Common Features Shown by Prokaryotic Organisms such as Bacteria

BACTERIA: Microscopic organism that causes diseases
