Process of Science and Plant Biology

This set of flashcards covers the key concepts in the process of scientific experimentation, aspects of plant biology, and characteristics of different plant types.

What are the steps in the process of science?

observation, hypothesis, prediction, design and run, statistical analysis, conclusion repetition

What is a Null Hypothesis?

Assuming there is no observed relationship so its due to random chance or experimental error.

What is the Alternative Hypothesis?

An explanation for the cause of an observation. This BLANK because BLANK

What is the structure of a Prediction?

IF [alternative hypothesis is true], THEN [X should be the result of Y].

What is the purpose of a Control Group in an experiment?

What is a Negative Control?

What does Replication in experiments refer to?

The repetition to estimate variability

Explanatory variable

Response Variable

the effect measured in the experiment.

What are the characteristics of Monocots?

One cotyledon, parallel leaf, fibrous roots, and petals in multiples of three.

characteristics of Dicots?

Two cotyledons, branching leaf, tap roots, and petals in multiples of four or five.

scattered throughout the stem and parallel veins in leaves.

What is the vascular tissue arrangement in Dicots?
