Scientific Method
This is the first step of the scientific method where you use your senses to gather information.
What is an observation?
This type of variable never changes between groups.
What is the control variable?
Plants are eukaryotic, multicellular, and this type of feeder.
What are autotrophs?
Mosses, liverworts, and hornworts belong to this plant group.
What are bryophytes?
Bryophytes often live in this type of environment because they cannot store water.
What is a moist or humid environment?
Ferns belong to this group of seedless vascular plants.
What are pteridophytes?
This step forms a testable statement based on past experience.
What is a hypothesis?
This variable is changed by the scientist during an experiment.
What is the independent variable?
Plants can reproduce in these two ways.
What are sexually and asexually?
Bryophytes lack these two vascular tissues.
What are xylem and phloem?
Bryophytes are known as this because they are the first to inhabit wetlands and help build soil.
What are pioneer plants?
Ferns use these for reproduction instead of seeds.
What are spores?
This step is when you apply your hypothesis to a specific testable situation.
What is a prediction?
This variable is measured as a result of changes in the independent variable.
What is the dependent variable?
This type of tissue allows plants to grow tall by supporting their bodies and moving materials.
What is vascular tissue?
These structures anchor the moss but do not absorb water.
What are rhizoids?
This wetland type contains tall grasses and reeds.
What is a marsh?
This structure on fern fronds releases spores.
What is the sorus?
This step includes carrying out an experimental procedure.
What is the test?
This group serves as the baseline and is not exposed to the independent variable.
What is the control group?
This vascular tissue transports water and minerals.
What is xylem?
This stalk lifts the capsule higher so spores can spread farther.
What is the seta?
This wetland type is a “flooded forest” with trees and shrubs.
What is a swamp?
The fern gametophyte contains both male and female parts and grows into this next stage after fertilization.
What is the sporophyte?
Provide an example of an experiment, creating their variables and their two groups within a test.
Teacher's Discretion.
This group tests whether the hypothesis is supported and has the independent variable changed.
What is the experimental group?
This vascular tissue transports sugars and proteins.
What is phloem?
Mosses need this environmental condition because sperm must swim to the egg.
What is water (or a moist environment)?
This wetland type has acidic, low-nutrient peat and is dominated by Sphagnum moss.
What is a bog?
In ferns, this happens to the gametophyte after the sporophyte matures.
What is it disintegrates?
