Introduction

The Scope of Biology

Chapter 1

Concept 1.1

Biology explores life from the global to the microscopic scale.

Key TermsBiosphereEcosystemOrganismCellDNA Gene

The Biosphere

Signs of life at the Global Scale

Consists of all the parts of the Earth that are inhabited by living things

EcosystemsCommunity

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

Woodland Ecosytem

OrganismsIndividual living

thingsLargeSmallMicroscopic

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 TermsSpeciesDomainUnicellularProkaryotic cellEukaryotic cellMulticellular

Life’s Diversity of SpeciesBiodiversity – the variety of life on Earth

What does it mean to have biodiversity?

Classifying Life: The Basic IdeaAs humans we tend to group items in

categoriesClassification as a postal address

The Three Domains of LifeArchaea – prokaryotic, unicellular

Bacteria – prokaryotic, unicellular

Eukarya – eukaryotic, multicellular

Concept 1.3

Ten themes unify the study of life

Key TermsSystemPhotosynthesisProducerConsumerHomeostasisAdaptationPopulationNatural SelectionEvolution

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 functionWould a flipper help a bird fly?Would a fish be able to swim with feathers?

Beak DesignScooping fish from waterEating large preyEating nectar from a flowerEating seedsEating insects from dead treesProbing mud for invertebratesCatching 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 lifeMedicineEnvironmental Issues

10 – Scientific Inquiry

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