To function most efficiently, a cell must be

Small in size. Why?

2

As cell size increases, the surface-area-to-volume ratio

decreases.

3

The size to which a cell can grow is limited by its

surface area.

4

Surface area is an important factor in limiting cell growth

because

the cell may become too large to take in enough food and to

remove enough wastes.

5

When the volume of a cell increases, its surface area

increases at a slower rate.

6

The smallest units of life are

cells

7

A microscope with a 4x objective lens and a 20x

ocular lens produces a total magnification of

80x

8

Fuzzy images viewed with a microscope may be due to

poor

resolution.

9

A cell that requires a lot of energy might contain large

numbers of

mitochondria.

10

The image produced by a microscope is called

a micrograph.

11

The metric system of measurement is based on

powers of

10.

12

Only eukaryotic cells have

membrane-bound organelles.

13

A structure within a eukaryotic cell that performs a specific

function is called a(n)

organelle.

14

The packaging and distribution center of the cell is

the

Golgi apparatus.

15

In a cell, proteins are made on the

ribosomes.

16

Plant cells have a large membrane-bound space in

which water, waste products, and nutrients can be stored.

This space is called the

vacuole.

17

This term refers to: surrounds cell membrane and provides

support

cell wall

18

The double membrane surrounding the nucleus is

called the

nuclear envelope.

19

Phospholipids are molecules that

channel proteins.

20

Which type of molecule forms a lipid bilayer within a cell

membrane?

phospholipid

21

This term refers to: single celled organisms that lacks a

nucleus and other internal components

prokaryote

22

system of internal membranes that move proteins and other

substances throughout the cell

endoplasmic reticulum

23

in plants, organelles that use light to make organic

compounds

chloroplasts

24

Smooth ER lacks

ribosomes

25

True of false: Chloroplasts have DNA that is different

from nuclear DNA.

true

26

True of false: As a cell gets larger, its surface-area-to-volume ratio decreases.

true

27

True of false: A phospholipid is a lipid made of a

phosphate group and two fatty acids.

true

28

True of false: Ribosomes are the sites of ATP production.

false

29

True of false: Most of a cell’s ATP is produced in the

cell’s mitochondria.

true

30

True of false: Mitochondria contain DNA.
