What are the five kingdoms of living organisms?
Animals, Plants, Fungi, Prokaryotes, and Protoctists
What are animals?
Multicellular organisms with nervous coordination; they cannot photosynthesise and store carbohydrate as glycogen
What are plants?
Multicellular organisms that carry out photosynthesis, store carbohydrates as starch, and have cell walls
what are protoctists
Mostly single-celled organisms with features of animals or plants. Some are pathogenic, like Plasmodium. examples are chlorella and amoeba
what are fungi
Can be single-celled or multicellular; do not photosynthesise, feed by saprotrophic nutrition, and store glycogen. Examples are yeast and mucor
what are prokaryotes
Single-celled organisms (like bacteria) without a nucleus. Examples: Lactobacillus bulgaricus, Pneumococcus
what are viruses
Non-living infectious agents made of protein and genetic material that reproduce inside living cells
what are eukaryotic cells
Complex cells with membrane-bound organelles, including a nucleus. Found in animals, plants, fungi, and some protoctists
what are prokaryotic cells
Simple, small cells without a nucleus, found in bacteria
what is a pathogen
A microorganism that causes disease
Glycogen
Energy store in animals and fungi
Starch
Energy store in plants
Cellulose
Found in plant cell walls
protoctists structure
chlorella- plant cell like
amoeba- animal cell like. Lives In pond water.
there is also plasmodium which causes malaria
bacteria structure and features
lactobacillus bulgaricus- can be used to make the milk go sour and turn into yogurt. its rod shaped
pneumococcus- round in shape and causes pneumonia
viruses structure and features
