We have now begun Unit 2 in the Text: Homeostasis in Organisms. There are 34 vocabulary words. You want to be certain you learn these. Strive for 10 out of 10 on this homework which is number 3 for the term and is due to me by Friday, March 7th.
Question #1: In a plant cell, the synthesis of sugar compounds from inorganic raw materials occurs in the
1) cell membrane
2) mitochondria
3) nucleus
4) chloroplasts
Queston #2: Which word equation represents the process of photosynthesis?
1) glucose yields alcohol plus carbon dioxide
2) carbon dioxide plus water yields glucose plus oxygen
3) chlorophyll plus water yields glucose plus alcohol
4) glucose plus oxygen yields carbon dioxide plus water
Question #3: Which activity occurs during the process of photosynthesis?
1) Chemical energy from organic molecules is converted into light energy
2) Organic molecules are absorbed from the environment.
3) Organic molecules are converted into inorganic food molecules
4) Light energy is stored as chemical energy in organic molecules.
Question #4: The basic raw materials of photosynthesis are
1) sugar and carbon dioxide
2) oxygen and water
3) water and carbon dioxide
4) oxygen and sugar
Question #5: Which compound is fromed as a common product of the process of photosynthesis?
1) DNA
2) sugar
3) chlorophyll
4) carbon dioxide
Question #6: Which of the following produced by a snail in a pond is used by a plant living in the same pond?
1) oxygen
2) carbon dioxide
3) food
4) egg cells
question #7: Which factor LEAST influences the rate of photosynthesis?
1) atmospheric concentration of carbon dioxide
2) time of day
3) number of chloroplasts
4) concentration of nitrogen in the air
Question #8: Energy for use in cells is stored in the form of
1) chemical bond energy
2) physical energy
3) heat energy
4) mechanical energy
Question #9: In which process do organisms transfer the chemical bond energy in organic molecules to ATP molecules?
1) excretion
2) cellular respiration
3) autotrophic nutrition
4) photosynthesis
question #10: Without chloroplasts and light energy, the process of photosynthesis in plants would not occur. Using one or more complete sentences, name two raw materials that are also necessary and describe why they are important.
