Plant Growth and Changes Quiz 1 Study Guide Parts of an Experiment Testable question - the question you want to answer with your experiment Hypothesis - an educated guess of what will happen based on what you already know Materials - the items you need for the experiment Procedure - the steps you follow to perform the experiment Variables - the one you change (manipulated), the ones you keep the same (controlled) and the one that you measure at the end of the experiment (responding) Observations - what you experience with your five senses Conclusion - what your observation has taught you; did you answer the question? Key Terms Anther - the male part of the flower that consists of a long stalk and a bulb on the tip end Bulb - an enlarged underground section of a stem that will grow into a new plant when planted Erosion - the wearing away by the action of water, wind, or glacial ice Flower - the part of the plan that produces the seeds Fruit - the flesh, often sweet part of a plant that holds the seeds Leaves - the green structures on the branches of plants which make the plant’s food. Nutrient - a substance that provides nourishment Pistil - the female part of the flower containing the egg or eggs in its swollen Pollination - the transfer of pollen from the male part of a flower to the female part Roots - the network of tubules and fibres that grow from the base of the plant Seed - a structure containing a tiny embryo plant and stored food Stem - the main body of the plant above ground that supports the branches and leaves Key Concepts What different items or products do we get from plant sources? How do plant roots prevent soil erosion? What is the oxygen cycle? Why is it important? What are the different parts of a plant? What is the function/purpose of each part? What are the two types of root systems? What are the different parts of a flower? What are the different types of stems? What are the different types of leaves? What are the different types of leaf arrangements?
