The Great Diversity of LifeUnit 3: Cells Chapter 7: Cell Structure and Function Section 7-4: The Diversity of Cellular Life Text pages:
Vocabulary Cell specialization Tissue Organ Organ system
4 Levels of OrganizationCells (muscle cells) Tissue (smooth muscle tissue) Organ (stomach) Organ System (digestive system)
Life surrounds every corner of the planet.Below the earth Deep under the sea Inside of bodies
REMEMBER… All living things are composed of cells.Cells are the basic living units of all organisms.
Unicellular OrganismsUnicellular = single celled organisms Do everything you expect a living thing to do. NUMEROUS- dominate life on earth Examples: yeast, algae cells, bacteria
Multicellular OrganismsMany cells Much variety and many types Success depends upon communication Cell specialization: process through which cells within the organism can develop in different ways to perform different tasks.
Red Blood Cell SpecializationTransport O2 Contain protein that binds to O2 in the lungs and carries it throughout the body.
Pancreatic Cell SpecializationPancreas produces proteins that make digestion possible. Contains many ribosomes and rough ER where proteins are produced.

Chapter 2 Bell work! Write the objectives in you notebook for today, Leave two lines so you can answer these questions at the end of the day. DO NOT ANSWER.
Cell Boundaries Notes Biology I.
Cells: Prokaryotic vs. Eukaryotic. Cells Cells – basic unit of living organisms. Level of organization: < cell < tissue < organ < organ system < organism.
