Prokaryotes- Bacteria Cell 0.0 / 5 ? Applied ScienceProkaryotes- Bacteria CellBTEC NationalOther Created by: Rumana.ACreated on: 18-04-18 19:42 What are bacteria cells made up of? Single cells with no membrane 1 of 14 What is the function of Plasmids? Carry genes that may benefit the survival of the organism 2 of 14 What is the function of Cytoplasm? Site of many metabollic processes 3 of 14 What is the function of Ribosomes? Protien synthesis occurs, 70S ribosomes 4 of 14 What is the function of the Capsule? Protects the cell from drying out and being engulfed by white blood cells, helps cells stick to surfaces 5 of 14 What is the function of the Cell wall? Protects and supports each cell, molecule made up of a sugar and amino acid called peptidoglycan 6 of 14 What is the function of the Nucleoid? Region of DNA and controls cellular activity 7 of 14 What is the function of the Flagellum? Long, thin, whip-like structure, allows bacterial movement 8 of 14 What is the function of the Pilus? Thin, rigid fibre made up of proteins that are attatched to the bacterial cell 9 of 14 What is transcription? Process in which mRNA transcripts genetic material to be translated for the production of proteins 10 of 14 What is translation? Production of bacterial protien, occurs at the ribosomes 11 of 14 What is Gram-negative bacteria? DOES NOT retain the gram stain when washed with acetone and alcohol because the cell wall has an outer layer 12 of 14 What is Gram-positive bacteria? DOES retain the gram stain because the thick peptidoglycan wall absorbs the stain and they do not have an outer wall 13 of 14 Why is Gram-negative more resistant to antibiotics than Gram-positive? Because Gram-negative has a cell wall with an outer membrane, which protects them from the antibiotic 14 of 14
