Living things vs Chapter : Classifying and exploring Lesson # 1: Characteristics of life Objective: Observe a list of events that characterize a living thing from a non-living thing. Non- living things What makes people and plants different from light and books?
First characteristics of life Chapter : Classifying and exploring Lesson # 1: Characteristics of life Objective: Observe a list of events that characterize a living thing from a non-living thing. Characteristics of life Organization: -For example, kitchen for cooking,and the bedrooms are for sleeping. -Living things are also organized. -Cell (smallest function of life) - Multicellular and unicellular organism
unicellular Single cell Life functions performed by single cell(eat,reproduce) Simple cell s structure Old organism Small cells Examples: algae, bacterias,archaea. multicellular Large number of cells Different cell perform different specific function(nerve cell,blood cell etc). Complex cell s structure Young organism Large cells Examples: Animals, plants,fungi
Second characteristics of life Growth and Development: -Growth depends on size Chapter : Classifying and exploring Lesson # 1: Characteristics of life Objective: Observe a list of events that characterize a living thing from a non-living thing. Characteristics of life -Unicellular growth depends on its unique cell size but the multicellular depends on the amount of cells -Development depends on shape (tadpole to frog) -
Third characteristics of life Reproduction: Chapter : Classifying and exploring Lesson # 1: Characteristics of life Objective: Observe a list of events that characterize a living thing from a non-living thing. Characteristics of life -For living things to continue to exist, organisms must reproduce -Makes one or more organism -Type of reproduction : 1- Division (bacterias), 2-Specialized cell ( humans, animals or multicellular). - Some can reproduce hundreds at a time(frogs)
Fourth characteristics of life Chapter : Classifying and exploring Lesson # 1: Characteristics of life Objective: Observe a list of events that characterize a living thing from a non-living thing. Responses to stimuli: -Internal stimuli ( You feel hungry and then look for food) Characteristics of life -External stimuli ( many plants will grow toward light)
Fifth characteristics of life Chapter : Classifying and exploring Lesson # 1: Characteristics of life Objective: Observe a list of events that characterize a living thing from a non-living thing. Characteristics of life Homeostasis: -Organism ability to maintain steady internal conditions when outside change -Examples: Cell s condition for a healthy organism
Sixth characteristics of life Chapter : Classifying and exploring Lesson # 1: Characteristics of life Objective: Observe a list of events that characterize a living thing from a non-living thing. Characteristics of life Energy: -Organism use energy for different activities(transport substances, make new cell, perform chemical reactions) - Energy cycle: Organism energy depends on other organism
How did Aristotle had organized organism? Chapter : Classifying and exploring Lesson # 2: Classifying organism Objective:. Classify organism according to their physical structure and characteristics Classifying living things - Placed organism into two groups: plants and animals - Classified animals based on presence of red blood, the animals environment and the shape and size. - Classified plants according to the structure,size, tree, shrub,or an herb
Robert Whittaker proposed five kingdom system: Chapter : Classifying and exploring Lesson # 2: Classifying organism Objective: Classify organism according to their physical structure and characteristics Determining kingdoms - Bacteria: unicellular organism - Archaea: Unicellular organism that lives in extreme environment - Protista: Unicellular, more complex than archaea and bacteria - Fungi: Unicellular or multicellular, absorb energy - Plantae: multicellular, make their own food - Animalia: multicellular take their own food
Chapter : Classifying and exploring Lesson # 2: Classifying organism Objective: Observe a list of events that characterize a living thing from a non-living thing. Determining Domains Determining Domains Systematics proposed kingdoms divided into two groups: - Prokarya : Bacterias, Archaea - Eukarya: Protista,Fungi,Plantae, Animalia
Chapter : Classifying and exploring Lesson # 2: Classifying organism Objective:Classify organism according to their physical structure and characteristics -Binomial Momenclature: gives each organism a two-word scientific name Example: Ursus arctos(brown bear) Dichotomous Keys - Descriptions arranged in pairs Scientific Name Cladograms - Relationship among organism and ancestors
Chapter : Classifying and exploring Lesson # 2: Classifying organism Objective:Classify organism according to their physical structure and characteristics Dichotomus keys: Scientific Name
