Title: Which of the following statements about cells is true?


1
Which of the following statements about cells is
true? a. Cells are the structures that contain
all of the materials necessary for
life. b. Cells are found in all
organisms. c. Cells are sometimes specialized
for particular functions. d. All of the above
2
Which of the following statements about all
living things is true? a. All living things
reproduce sexually. b. All living things have
one or more cells. c. All living things must
make their own food. d. All living things
reproduce asexually.
3
Organisms must have food because a. food is a
source of energy. b. food supplies cells with
oxygen. c. organisms never make their own
food. d. All of the above
4
A change in an organisms environment that
affects the organisms activities is a a.
response. b. stimulus. c.
metabolism d. producer
5
Organisms store energy in a. nucleic
acids. b. phospholipids. c. lipids
d. water.
6
The molecule that contains the information about
how to make proteins is a. ATP. b.
a carbohydrate. c. DNA. d.

7
What is the difference between asexual
reproduction and sexual reproduction?
  • Sexual
  • Requires two parents
  • Babies have traits from both parents
  • Asexual
  • Requires only 1 parent
  • Babies IDENTICAL to parent

8
What is ATP, and why is it important to a cell?
  • ATP is the cells main energy chemical
  • It provides the energy cells need for everyday
    activities.

9
A flame can move, grow larger, and give off heat.
Is a flame alive? Explain.
  • No
  • It cannot reproduce
  • It is not made of cells
  • It doesnt have DNA
  • It doesnt use energy, it makes energy

10
Based on what you know about carbohydrates,
lipids, and proteins, why is it important for you
to eat a balanced diet?
  • Different types of food provide different things
    for your body

  • Proteins build body parts

    organism

13
  • a. cell

    next

14
