Salt Tolerance Lab

Question 1

Independent Variable

Answer 1

What the experiment was designed to test; manipulated by the researcher

Question 2

Dependent Variable

Answer 2

Measures something the experimental variable is predicted to effect

Question 3

Control

Answer 3

Normal conditions; allows for comparison between what is being tested and normal conditions

Question 4

T-Test

Answer 4

Anything less than P < .05 is significant.

Averages between two groups and the variability between raw scores in a group to calculate how likely the observed differences in the averages are random or due to chance

Question 5

Know how salinity is and how it affects plant growth

Answer 5

Increased salinity = Decreased plant growth

Question 6

How to set up an experiment to set up plant growth

Answer 6

Various groups of seeds with different salt concentrations, (1%, 2%, 3%, 4%, and 5%), and a control (no added salt) and observe how many seeds germinate in the varying conditions

Question 7

Salinization

Answer 7

Increasing salt content in the soil

Question 8

Germination

Answer 8

growth; the radicle (embryonic root) breaking through the seed coat and emerging as a healthy white filament

Question 9

Radicle

Answer 9

Embryonic root
