| answer | question |
|---|---|
| Invest 4 Domain | 1.Vocab 2.Levels of Complexity 3.Bacteria and Fungi structures 4.Why is Bacteria and Archaea unique |
| 1. Vocabulary 4.1 | 4.1 4.3 4.4 |
| an organism so small that a microscope must be used to view it -use a microscope to see it | microorganism |
| a species of rod-shaped bacteria in the large intestine of human and other animals -type of large rod-shaped thing | E.Coil |
| a microscopic, single-celled organism that lacks a nucleus and organelles-(prokaryotic) -NO nucleus | Bacteria |
| a eukaryotic organism, including molds,mushrooms and yeast. Can be single-celled or multicellular -HAS a nucleus | Fungi |
| a growth of organisms on a prepared material -organisms prepared | Culture |
| an experiment test used to compare results with tests where variable was changed -experiment with change | Control |
| a particle made of 2 or more smaller particles held together by chemical bond -particles,chemical bond,2 | Molecules |
| a particle that is the basic building block of matter -building blocks of matter | Atoms |
| a reproductive cell distributive through the air -reproduce through air | Spores |
| a group of organisms of the same species living together. A bacteria ------ is a visible group of bacteria -Bacteria are together and seen | Colony |
| 1. Vocabulary 4.3-4.4 | 4.1 4.3 4.4 |
| an organism that breaks down dead material and returns nutrients to the soil -breaks dead | Decomposers |
| a system or way of organizing living things -system | Classification |
| a microscopic single-celled organism that lacks a nucleus and organelles (prokaryotic) different cell wall,membrane then bacteria or eukaryotes -single-celled,different | Archaea |
| an organism with cells that have a nucleus -nucleus | Eukaryote |
| a single-celled organism with no nucleus -NO nucleus | Prokaryote |
| One group in the most currently accepted biological classification system -group | Domain |
| 2.Levels of Complexity | Building Blocks |
| The building blocks of life are __________ The building blocks of cells are_______ The building blocks of cell structures are______ The building blocks of ____ are atoms | Cells Organelles and Structures Molecules Molecules -all life |
| 3.Bacteria and Fungi Structures | Questions and Answers |
| Fungi cell structures (list) Bacteria cell structures (list) | -Cell membrane,Cell wall,Central vacuole,Cytoplasm,Endoplasmic reticulum,Mitochondrion,Nucleus,Ribosome -Cell membrane,Cell wall,Cytoplasm,Plasmid(DNA),Genetic material(DNA),Ribosome |
| 4.Bacteria and Archaea | unique |
| How is Archaea unique from Bacterial cells? _______________________________________________________________________ | Archaea is prokaryotic like Bacteria and has the similar cell structures as Bacteria, but Archaea has DIFFERENT building blocks(3-cell wall&membrane and ribosome) from Bacteria |
| RECAP! | building blocks=life Fungi and Bacteria are different Bacteria and Archaea are similar but the building blocks for archaea makes it different |
| GOOD LUCK/JOB | Exam material NEXT! |
| Investigation 4 Study Guide | 6 parts vocab cell structures building blocks bacteria cell fungi cell archaea cell |
| Part 1: Vocabulary Eukaryote Prokaryote Archaea Bacteria Fungi Atoms Molecules | -organism with cells that have a nucleus -single-celled organism no nucleus -microscopic single-celled organism lacks nucleus&organelles different cell walls and membranes than bacteria or eukaryotes click to finish |
| -microscopic, single-celled organism lacks a nucleus&organelles -eukaryotic organism, molds, mushrooms, and yeasts;can be single-celled or multicellular click to finish | -particle made up of two or more smaller particles held together by chemical bonds -particle that is the basic building block of matter |
| Part 2: Cell Structure (review) What is a Protist Cell,what does it look What is a Fungal Cell,what does it look What is a Animal Cell,what does it look What is a Bacterial Cell,what does it look What is a Fungal Cell,what does it look | -oval,E-eukaryote -rectangle with opening,E-eukaryote -circle,E-eukaryote -oval,P-prokaryote -square,E-eukaryote |
| Part 3:Building Blocks of Life (review) What are the Levels of Complexity What are some examples | atoms-molecules-cell structures-cells ATOMS (C, H, N, O, P) →MOLECULES (carbohydrates, lipid, protein) →CELL STRUCTURES (any of them!) →CELLS (any of them! As long as they contain the cell structure you built) -look at exam page to see your examples |
| Part 4: Bacterial Cells Explain how bacterial cells reproduce. What role do plasmids play? List 2 ways bacteria can be beneficial and 2 ways bacteria can be harmful Explain what happens when bacteria is added to yogurt | -reproduce asexually-grow,make a copy of their DNA,split into two. Plasmids-unique to bacterial cells and can be exchanged through a tube between two bacteria and each new cell gets new DNA. allows the bacteria to acquire new traits. click to finish |
| -Potential ways bacteria can be BENEFICIAL - antibiotics, decomposers, digestion, food production Potential ways bacteria can be HARMFUL - bacterial infection (ex E coli), epidemics (plague, typhus, lyme disease) click to finish | -added to yogurt, bacteria break down the sugar in milk-lactose. eat the lactose for food and give off lactic acid as a waste product |
| Part 5: Fungal Cells Explain how fungal cells reproduce List 2 ways fungi can be beneficial and 2 ways fungi can be harmful Explain what happens when yeast is added to bread dough How is the fungal cell unique? | Fungal cells produce both asexually&sexually. Spores-fungus reproductive cell. travel by wind, water, animals, or air - this is how mushrooms and molds reproduce sexually. Yeast in bread reproduce asexually by budding. click to finish |
| BENEFICIAL-penicillin (antibiotic made from fungi), molds that make cheese (brie, gorgonzola), yeast makes bread, mushrooms, decomposers HARMFUL-poisonous mushrooms (Destroying angel), mildew- respiratory issues, asthma, irritations click to finish | Yeast consumes carbohydrates in the bread and eliminates carbon dioxide as waste.gas causes bread to expand Fungal cells-opening in cell wall allows fluids, proteins, and even nuclei to flow. single-celled organism have more than 1 nucleus |
| Part 6: Archaean Cell What cell is most like archaea,What is the Difference. Explain the classification system of living thing. What were the 5 kingdoms? How are living things classified now. What is most like us? | -Bacterial cell 3 different cell structures-ribosome,cell wall&membrane -1st-2 kingdoms-plants&animals,2nd-5 kingdoms-plants,animals,protist,bacteria,fungus,3rd(present)-bacteria,archaea,eukaryotes -fungus have a nucleus-eukaryotic like humans |
