Tuesday in class Protist Quiz Introduce Hierarchy (organization) of cells

Read C 1. 3, pages 26 - 32 Answer questions 1 – 5 in 1. 3 Review (p. 32) 1. 2. 3. 4. The three domains and their cell types are: Specialization is Levels of organization as a tree: Difference between cell in unicellular and multicellular organism: 5.

7. L. 1. 3 – Summarize the hierarchical organization of multicellular organisms from cell tissue organ system organism. Levels of organization

Specialized • To have a specific function. • Example: A violinist. • Non-Example: Oneman band.

Cell • Smallest living thing • Examples: Muscle cells, Bone cells, Skin cells, Eye cells, Blood cells, Neurons (brain cells) • Non-Examples: Biceps, Triceps, Ear, Eye, Brain, Organelles

Tissue • Group of cells working together to perform the same function. • Examples: Muscle, Blood, Fat, Cartilage, Epithelial • Non-Examples: Neurons, Muscle Cells, Femur

Organ • Group of tissues working together to perform the same function. • Examples: Stomach, Lungs, Skin, Brain, Heart, Bones, Kidneys • Non-Examples: Muscle, Blood, Hair, Adipose, Cartilage

Organ System • Group of organs working together to perform the same function. • Examples: Digestive, Circulatory, Respiratory, Excretory, Nervous, Muscular, Skeletal. • Non-Examples: Heart, Lungs, Stomach, Bees, Trees, Kidneys

Organism • Object that performs all life functions. • Examples: Humans, Plants, Mushrooms, Insects • Non-Examples: Rocks, Viruses, Fire

NOT highly specialized If piece is broken off organism it will regenerate grow back!

Multicellular – Eukaryotic cells Plant – Animal - Fungus • Specialization – each cell in the organism has a different job • Single cell of multicellular organism CAN NOT survive on its own • Members of a community that work together to support organism

Science Thoughts 3/1 How are cells classified starting with individual cells and ending with organisms? Cell – Tissue – Organ System - Organism

Thursday in class 51 - Organization of Multicellular 52 - Levels of Organization

Science Thoughts 3/2 When is the Cells Unit Test and when is the Life Project due? Test: Friday, March 9 Project: Monday, March 12

Friday in class 53 – Cells R Us 1. The three domains and their cell types are: (prokaryotic) Bacteria, Archaea and Eukarya 2. Specialization is each cell having a different job 3. Levels of organization as a tree: cell: plant; organ: leaf; organ system: leaves, stems, roots 4. Difference between cell in unicellular and multicellular organism: unicellular does all tasks, multicellular does specialized tasks 5. Using Models: 1. similar to object represented: help to understand 2. Different from object represented: not fully accurate
