Mrs. Hamilton Introduction

The Scope of Biology Chapter 1

Concept 1.1 Biology explores life from the global to the microscopic scale. Key Terms Biosphere Ecosystem Organism Cell DNA Gene

The Biosphere Signs of life at the Global Scale Consists of all the parts of the Earth that are inhabited by living things

Ecosystems Community of living things in an area, along with the nonliving features of the environment that support the living community Woodland Ecosytem

Organisms Individual living things Large Small Microscopic

Cells Life's basic units of structure and function All organisms are made of one or more cells

DNA & Genes DNA is the chemical responsible for inheritance, and is found in the nucleus of every cell Spread in bits and pieces along the DNA molecule are genes – which code for specific proteins

Concept 1.2 Biology explores life in its diverse forms Key Terms Species Domain Unicellular Prokaryotic cell Eukaryotic cell Multicellular

Life’s Diversity of Species Biodiversity – the variety of life on Earth What does it mean to have biodiversity?

Classifying Life: The Basic Idea As humans we tend to group items in categories Classification as a postal address

The Three Domains of Life Archaea – prokaryotic, unicellular Bacteria – prokaryotic, unicellular Eukarya – eukaryotic, multicellular

Concept 1.3 Ten themes unify the study of life Key Terms System Photosynthesis Producer Consumer Homeostasis Adaptation Population Natural Selection Evolution

1 – Biological Systems “The whole is greater than its parts” A system has properties based on the arrangement and interactions of its parts Interactions with organisms and the non-living parts of the environment “put the system in ecosystem”

2 – The Cellular Basis of Life All organisms are made of cells These cells are then organized into more complex structures

3 – Form and Function Which is the better tool – hammer or screwdriver? The best form depends on its function Would a flipper help a bird fly? Would a fish be able to swim with feathers?

Beak Design Scooping fish from water Eating large prey Eating nectar from a flower Eating seeds Eating insects from dead trees Probing mud for invertebrates Catching insects in flight

4 – Reproduction and Inheritance Organisms have to be able to reproduce Using genetic information (DNA) from parents you can see how it is passed along from generation to generation

5 – Interaction with the Environment No organism is isolated from its surroundings Photosynthesis – uses carbon dioxide, water, and sunlight to produce oxygen and energy Stepping out into the sunlight – causes you to squint Venus flytrap – designed to detect touch which causes them to close

6 – Energy and Life Moving, growing, reproducing and other life activities require energy You can trace energy (light, chemical, and heat) in different ecosystems Producers (Autotrophs) vs. Consumers (Heterotrophs)

7 - Regulation Organisms have to regulate the internal conditions The ability of birds and mammals to regulate body temperature is an example of homeostasis (steady state) Mechanisms of homeostasis enable organisms to regulate their internal environment, despite changes to their external environment

8 – Adaptation and Evolution Adaptations are inherited traits that help the organism survive and reproduce in a specific environment Evolution means “change over time” – specifically a generation to generation change that occurs over a long period of time

9 – Biology and Society The more we learn about biology – the more it impacts daily life Medicine Environmental Issues

10 – Scientific Inquiry Involves asking questions about nature and then using observations or experiments to find possible answers to those questions
