micro-organisms

• Learning science is the study of how people learn and the application of scientific principles to improve educational practices.
• viruses are accelular
• viruses are eukaryotes
• viruses are pathogens
• viruses are not living are considred dominant
• viruses are parasites
• viruses are made up of nucleuic acid(DNA/RNA)
• Viruses are cannot replicate without finding a host
• fibres> viruses use this to stick to their hosts
• protein shield it protects the nucleic acids
• DNA>deoxyribonucleic acid
• RNA>ribo nucleic acid
• viruses have a rod/spherical shape and are surrounded by a lipid envelope
• bacteria> are prokaryotes are unicellular and have a cell wall
• bacteria are found in the kingdom of monera
• bacteria the cell is surrounded by a slime capsule
• bacteria contain DNA
• bacteria move using flagella
• fungi are decomposers and feed on dead organic matter
• fungi are eukaryotic, multicellular organism that reproduce sexually or asexually
• fungi can be parasitic and cause disease
• fungi produce spores through sexual reproduction
• fungi absorb nutrients through their hyphae
• fungi have hyphae which branch out to form mycelium
• bacteria also have different shapes
• some bacteria are autotrophics(produce their own food)
• bacteria>use the flagella to move around
• bacteria> prokaryotes
• bacteria>are unicellular
• fimbriae is found on top of the glycocalyx
• bacteria use the fimbriae to stick together
• glycocalyx protect the bacteria from harmful environment
• pili(pilus) is an organ used during conjuction
• conjuction is the process whereby the is a partial transfere of DNA from one organism to another
• bacteria have a slime layer/slime capsule which stops the bacteria from losing water or nutriens
• some bacteria their cell wall is surrounded by a slime capsule
• bacteria have a rigid layer
• cell wall,glycocalyx,cell membrane make up the cell envelope
