Science Starter 08-22-11 The word cell is used in many contexts (ways). List the different ways cell is used (outside of science class).
Review • Organism- Lion, butterfly, frog, gnat etc…. • Organ system- Cardiovascular, Skeletal, Integumentary (skin, nails and hair) etc… • Organ- Heart, liver, spleen, brain etc…. • Tissue- Connective, muscular tissue etc…. • Cells- Smallest unit of life, no cells =no life!!
What is the most basic unit of language/life? • Cells= Words • Tissue= Phrases or sentences • Organ= Chorus, hook or lyrics. • Organ system= A complete song, lyrics, hook • Organism= Complete album art work, production, songs. • Today we are going to study the “words”
EQ What are the functions of major cell organelles?
For example • Organelle- a specialized structure of a cell ( the generic term for anything in the cell) • Organelle= Cell parts • Ribosomes, Nucleus, cytoplasm
Chloroplast- Where photosynthesis occurs, converts energy for the cell. Found only in plants. Color: Green
Color: Green • Cell walls- Found only in plants protects and supports plant cell. • Vacuoles- storage unit of cell, stores food, water and waste significantly larger in Plant cells
Science Starter 8-23-13 What is the structure that most cells have? If you have STILL not finished your hand, do so now. I’m throwing away all the papers left in the room this afternoon If you have finished your hand, you may SILENTLY on something else or read.
Color: YOU Choose. (NOT GREEN) Cell membrane-- thin semi-permeable membrane that surrounds the cytoplasm of a cell. It allows certain substances into the cell, while keeping other substances out
Ribosomes- assembles proteinsby translating messenger RNA (found all throughout the cell) Cytoplasm- fluid that fills a cell,clear and gel-like appearance. Helps move materials around the cell.
Endoplasmic reticulum E.R- packaging system Rough E.R.- Presences of ribosome (proteins) Smooth E.R.- absences of ribosome (stores steroids)
Golgi appartatus- packaging and shipping molecules
Explain in your words what each function is • 1. Cell wall and Cell membrane • 2. Cytoplasm • 3. Mitochondria • 4. Chloroplast • 5. Nucleus • 6. Chromosomes • 7. Vacuole • DrawOR Act out your organelle and explain it’s function.
Centrioles • Ribosomes • Golgi Complex • Nucleus • Chromosomes • Lysosome • Rough Endoplasmic Reticulum
