PPT-Unicellular and Multicellular Organisms

LESSON 3 Unicellular Organisms Organisms that consist of one cell They are also known as microorganisms They also carry out all the life processes such as movement response respiration digestion excretion reproduction and growth. As living things are constantly being investigated, new attributes are revealed that affect how organisms are placed in a standard classification system.. . . Classifying Living Things. Carl Linnaeus was a . Unicellular Organisms. Some organisms are made up of only . one cell. .. We call these organisms . unicellular. which means one-celled.. These organisms are much . simpler. than most organisms that are made up of many cells.. Animal like, plant like and fungi like. Objectives. 1. Define . protist. .. 2. Describe the hypothesis for the origin of eukaryotes. . 3. Explain . protists. classification. . 4. Describe two major ways in which . Protists. (Algae). Autotrophs. – . photosynthetic. , have . chloroplasts. , all have chlorophyll a. Classified by . pigment. types / color group, food storage, cell wall composition (7 phyla). Produce most . Multicellular. Which is better?. Questions to Consider. How quickly can it reproduce?. How specialized can it be?. How large can it grow?. How long does it take to develop?. How long can it live?. How quickly can it adapt and evolve?. http://www.worldofteaching.com. A . view. of . the. . cell. . The Cell. The basic unit of an organism. Discovery made possible by the invention of the microscope. The. . history. of . the. . cell. Creating a T Chart of Benefits and Limitations. Structure. Unicellular Organism. Body is made up of a single cell. Multicellular Organism. Body is made up of numerous cells. Division of Labor. Unicellular Organism. Taxonomy is the science of naming and classifying organisms. The system used by biologists is called the . Linnnaean. System.. Carl Linnaeus was a Swedish biologist in the mid-1700s. He popularized a system of grouping organisms according to like characteristics and giving each group a specific name.. Made of only one cell!!. With a partner...brainstorm answers to the following questions. How do you think . unicellular organisms. ...eat, move, get rid of wastes, and reproduce?. 2) How do . multicellular. The Diversity of Life. Taxonomy . is the study and practice of classifying living organisms.. Modern taxonomy uses the three domain system.. Domain . Archaea. : . Unicellular and live in harsh environments; no nuclei. hodge. - podge group. Basics. Eukaryotic. 3 groups- animal like -. Protozoans. plant like- Algae. . fungi like- Slime molds. Evolved from a symbiotic relationship: 1 prokaryote engulfed another (like a mitochondrial or chloroplast like cell) . ). Protists. are….. organisms that cannot be classified into any other group (plant, animal, fungus, bacteria). o. rganisms that are typically made up of just one cell. o. rganisms that can be made up of many cells. Tuesday: Finish Test Analysis. Today:. List . the three components of the cell theory. Note Cards. Most missed quiz. Learning lab. Monday-Thursday. Mornings 7-7:20. Afternoons 2:45-3:15. Glue in your skeleton notes. Standards. GSE S7L1: Obtain, evaluate, and communicate information to investigate the diversity of living organisms and how they can be compared scientifically.. GSE 7L1b: Evaluate historical models of how organisms were classified based on physical characteristics how that led to the six-kingdom system (currently archaea, bacteria, protists, fungi, plants and animals).
