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-tovolume 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.
true
