The Great Diversity of Life Unit 3: Cells Chapter 7: Cell Structure and Function Section 7-4: The Diversity of Cellular Life Text pages: 190-193
Vocabulary Cell specialization Tissue Organ Organ system
4 Levels of Organization 1) Cells (muscle cells) 2) Tissue (smooth muscle tissue) 3) Organ (stomach) 4) 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 Organisms Unicellular = single celled organisms Do everything you expect a living thing to do. NUMEROUS- dominate life on earth Examples: yeast, algae cells, bacteria
Multicellular Organisms Many 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 Specialization Red Blood Cells Transport O2 Contain protein that binds to O2 in the lungs and carries it throughout the body.
Pancreatic Cell Specialization Pancreas produces proteins that make digestion possible. Contains many ribosomes and rough ER where proteins are produced.

Slide 1 of The Diversity of Cellular Life Copyright Pearson Prentice Hall The differences among living things arise from the ways in which cells.
Diversity of Cellular Life 7-4. Unicellular Organisms Cells are the basic units of all organisms, but sometimes a single cell is the organism A.k.a unicellular.
Chapter 3 Cellular Organization. Unicellular Organisms.
The diversity of life is so great that you might have to remind yourself that all living things are composed of cells, use the same basic chemistry, and.
7-4 Diversity of Cellular Life Page 190. A. Unicellular Organisms 1. Organisms that are made up of only 1 cell. – Examples: Yeast, Amoeba, Volvox Aureus.
7-4 the diversity of cellular life. Unicellular organisms Unicellular organisms perform all of life’s essential functions within a single cell. There.
Diversity of Cellular Life Unicellular vs. Multicellular Organisms.
A. Unicellular Organisms --Single-celled Organisms that do all a living thing would ----They dominate life on earth in terms of numbers IV. The Diversity.
Lesson Overview Lesson Overview Homeostasis and Cells Lesson Overview 7.4 Homeostasis and Cells.
Cellular Hierarchy S7L2c Explain that cells are organized into tissues, tissues into organs, organs into systems and systems into organisms.
Cellular Organization Sec From Simple to More Complex Many multicellular organisms have structures called organs that have a specific function and.
Chapter 7.4: The Diversity of Cellular Life. All living things (organisms) are made of cells that: 1.use the same basic chemistry and genetic code 2.contain.
The Diversity of Cellular Life. Unicellular Organisms 1. An organism that consists of a single cell is called a unicellular organism. Unicellular organisms.
Cells Objective: Students will be able to describe cell theory how cells are organized in multicellular organisms.

CHAPTER 3 LESSON 1 MULTICELLULAR ORGANISMS BY SOPHIE AND HAILEY.
7-2 The Plasma Membrane Mrs. Geist Biology, Fall Swansboro High School.
All cells are surrounded by a thin barrier called the cell membrane. Many cells also have a strong supporting layer around that membrane called the.
Chapter 7 Biology Cell structure and function. Discovery of cells In mid-1600’s microscopes were being used to observe living things 1665 Robert Hooke.
Cell Structure. All cells have the following parts: Cell Membrane- a thin coat of phospholipids that surround the cell. Creates a boundary between the.
The diversity of cellular life 7.4 Biology Mr. Hines.
4.3 Multicellular Organization Unicellular One cell carries out everything. Multicellular *Cells are differentiated to perform specific.
Chapter 7.3 & All organisms and all cells must maintain homeostasis (stable internal environment) and adjust to their environment. Cell membrane.
Transport Flowchart Transport of Materials Across a Membrane Active Phagocytosi s Pinocytosi s Ion Pump Facilitated Diffusion Osmosis Simple Diffusion.
Biology I. Copyright Pearson Prentice Hall 7-3 Cell Boundaries All cells are surrounded by a thin, flexible barrier known as the cell membrane. Many cells.
Vocabulary Unicellular- made up of only one cell. Multicellular- made up of more than one cell. Cytoplasm-jelly like fluid has many chemicals that.
Levels of Organization. Unicellular Organisms Single cell performs all life functions. It functions independently.
Ch. 7 – Cell Structure and Function Life is Cellular.
The Cell Theory 1. The cell is the basic unit of structure of all living things. § The smallest living things are one-celled or unicellular § Large organisms.
Cells: Prokaryotic vs. Eukaryotic. Cells Cells – basic unit of living organisms. Level of organization: < cell < tissue < organ < organ system < organism.
Cell Organelles and Organization. What to consider? Prokaryote- organisms that lack nuclei (bacteria) Eukaryote- organisms with a nuclei (plants and animals)
Chapter 1 What is life?. The Characteristics of Living Things Vocabulary all living things Organism-all living things All living things: Have cellular.
The Diversity of Cells Chapter 3: Section 1. Cells and the Cell Theory Robert Hooke - First to see blood, bacterial, and yeast cells First to observe.
Chapter 7 Cell Structure and Functions. Chapter Outline 7-1 Life is Cellular 7-2 Eukaryotic Cell Structure 7-3 Cell Boundaries 7-4 The Diversity of Cellular.
CELLS. CELLS CELL: Smallest unit of an organism that carries on life functions.
