BIOD 101 PORTAGE LEARNING MODULE 6 EXAM WITH BEST SOLUTIONS What is the nucleoid region used for? - To store genetic information in prokaryotes True or false: If false, make it true. The nucleoid region is bound by a membrane and does not contain bacterial chromosomes and DNA? - False The nucleoid region is NOT bound by a membrane and DOES contain bacterial chromosomes and DNA. Bacterial chromosomes are in what shape? - Circle Define plasmids - Small, circular region of DNA. How many plasmids do bacterial cells usually have? - Dozens Which organelle can carry small amounts of genetic info and can replicate independently of one another? - Plasmids The __________ is filled with __________ - intracellular region cytoplasm What is the responsibility of cytoplasm - Holding ribosomes and plasmids in the cell. Are ribosomes bound by a membrane? - No Cells can be broken down into what two groups? - Prokaryotic and Eukaryotic What type of cell contains a membrane bound nucleus, and organelles that are specific to each cell? - Eukaryotic What is the size range for Eukaryotic cells? - 10-100 micro meters What is the difference between animal and plant eukaryotic cells? - Animal cells don't have a cell wall. Plants have a rigid cell wall. Can eukaryotic cells be single or multicellular? - Both Which type of cell is less complex? - Prokaryotic Which type of cell lacks a nucleus and other membrane bound organelles? - Prokaryotic Which type of cell is smaller? - Prokaryotic What is the size range of a prokaryotic cell? - 1-5 micrometers Are prokaryotic cells always single celled? - Yes What 2 kingdoms are prokaryotic organisms apart of? - Bacteria and Archaea What is something eukaryotic and prokaryotic cells have in common? - Both have a plasma membrane, cytosol, and chromosomes What is unique about bacterial ribosomes? - Their RNA and protein are unique. This allows for the creation of antibiotics b/c they only target the unique RNA and protein in bacteria. Contents of bacterial cells are enclosed in what? - Plasma membrane What occurs in the plasma membrane? - Diffusion of ions/molecules and area for metabolic functions Prokaryotic cells do not contain a __________ which is important for __________ - mitochondria aerobic respiration How can a bacteria go through aerobic respiration without a mitochondria? - The bacteria's plasma membrane will fold to create a space for the chemical reactions in aerobic respiration
