 Workbook Questions from old textbook for
pages 36-39
 4. What might you have in common with a
slime mold? Both are alive!
 5. All organisms, including fish, trees, and
mushrooms, share 6 characteristics.
 In the space provided, write AT if the statement is
always true, ST if the statement is sometimes true,
and NT if the statement is never true.
 6. AT A cell has a membrane that acts as a
barrier between its contents and its environment.
 7. NT Adult complex organisms such as
monkeys and humans are made up of a few hundred
cells.
 8. ST Living things have more than one cell.
 9. ST A cell is too small to be seen without a
microscope.
 10. ST Cells perform specialized functions,
such as transporting signals and movement.
 11. Organisms respond to changes in their
environments called stimuli. What are three
examples of stimuli? Chemicals, gravity,
darkness, light, sound, taste, and touch
 12. The chemical reactions that happen inside
your body can also take place in any other type
of environment. True or False?
 13. When it is hot, your body sweats to maintain
a temperature of about 37°C. True or False?
 14. Suppose the abalone reproduces by
"broadcast spawning." The female shoots eggs
into the water, and the male shoots sperm into
the water. Is this sexual or asexual
reproduction? Explain. Sexual, two parents!
 15. Deoxyribonucleic acid provides instructions
for making molecules called proteins.
 16. When they reproduce, organisms pass on
copies of their DNA to their offspring.
 17.Offspring resemble their parents because of
heredity. True or False?
 18. Which of the following statements are true about
metabolism? (Circle all that apply.)
a. It requires energy
b. It is the sum of an organism's chemical
activities.
c. It occurs only in multicellular organisms.
d. It involves the breakdown of food.
 19. Growth in humans takes place as their cells divide
and produce more cells. How do single-celled
organisms grow? A single-celled organism grows
as the cell gets larger.
 20. Living things, such as the oak tree in Figure 7 on
page 39, may develop and change as they grow.
Living or
not?
