1. Introduction to Biology
Unit 1

2. Warm –up: What is Biology???
LIFE
STUDY OF
the study of life.

3. What makes something alive?
Change over time (evolve)
Respond to Stimuli
Gas exchange
Cells
DNA
Reproduce
Growth & Development
Maintain homeostasis (balance)
Obtain energy, release waste

4. 6 Kingdoms for Living Things
All living things are classified into one of 6 Kingdoms. These kingdoms are:
2 ___________________kingdoms - single celled and no nucleus (prokaryote)
_____________________ - single celled with a nucleus (eukaryote)
_____________________ - multicellular and eukaryotic, cell wall, decomposer
______________________- multicellular, eukaryotic, cell wall, producer
_____________________ - multicellular eukaryotic, consumers
Bacteria
Protista
Fungi
Plantae
Animalia

5. A ____________________________________ is a tool used to identify the scientific name of an organism. Under each picture, write the correct scientific name of the organism
Dichotomous Key
Deerus magnus
Deerus pestis
Deerus octagis
Deerus purplinis
Deerus deafus
Deerus humpis

6. Binomial nomenclature – 2 names
Scientific names have two words – __________________ and ______________. The first word is the genus. The second word identifies the species.
Example: Homo sapiens - Homo is the genus, sapiens is the species.
The scientific name of a grizzly bear is Ursus arctos.
What genus does the grizzly bear belong to? ___________________________
In the dichotomous key above, what genus do all of the organisms belong to? ______________________
Genus
species
Ursus
Deerus

9. PRACTICE INDEPENDENT VARIABLE – TYPE OF FERTILIZER
DEPENDENT VARIABLE – GROWTH OF PLANT
CONTROL GROUP – PLANT WITHOUT FERTILIZER
EXPERIMENTAL GROUP – PLANTS WITH FERTILIZERS
CONSTANTS – SAME AMOUNT OF FERTILIZER, SAME TYPE OF PLANT, SAME AMOUNT OF WATER

16. Graphing Warm-up: Given the information below make a line graph.
Plants are able to make their own food through a process called photosynthesis. One of the products of photosynthesis is oxygen. When plants are under water they release the oxygen in the form of gas bubbles. The more bubbles a plant produces, the more productive it is. The following data table shows a comparison of the number of bubbles produced between two different kinds of plants found in Lake Gaston. Data Table: Productivity of two plants found in Lake Gaston at various depth.
Depth in meters
Number of Bubbles per Minute: Plant A
Number of Bubbles per Minute: Plant B 2 29 21 10 45 40 16 32 50 25 20 34
