The light microscope uses a beam of electrons to magnify a specimen.
F
The cells of animals are prokaryotic
F
Each animal cell contains one or more chloroplasts
F
Mitochondria contains DNA
t
The scanning tunneling microscope can be used to view living organisms
t
Two different structures that all cells have are cell membrane and a cell wall.
F
Ribosomes are the sites of ATP production.
F
The only difference between a plant and an animal cell is that plant cells have chloroplasts
F
Lysosomes transfer energy from organic compounds to ATP
F
Robert Hooke observed cork cells under a microscope
T
One important organelle that helps maintain homeostasis by moving substances from one part of the cell to another is the
endoplasmic reticulum
A cell that requires a lot of energy might contain large numbers of
mitochondria
THe cell membrane
encloses the contents of a cell
allows materials to enter and leave the cell
is selectively permeable
The organelles asociated with plant photosyntheses are
chloroplasts
The organelles associated with plant photosynthesis are the
cell membrane
The Golgi apparatus is an organelle that
receives proteins and lipids from the endoplasmic reticulum
packages molecules made in the endoplasmic reticulum
is involved in the distribution of proteins
Short hairlike structures that protrude from the surface of a cell and are packed in tight rows are called
cilia
All the following are found in both plant and animal cells, except
a cell wall
The packaging and distribution center of the cell is the
Golgi apparatus
Which of the following is an example of a prokaryotic cell?
bacteria
Which type of molecule forms a lipid bilayer within a cell membrane?
phospholipid
In a cell, proteins are made on the
ribosomes
The double membrane surrounding the nucleus is called the
nuclear envelope
To function efficiently a cell must be
small
Only eukaryotic cells have
membrane-bound organelles
A structure within a eukaryotic cell that performs a specific function is called a(n)
organelle
How are chloroplasts similar to mitochondria
They both contain DNA
Plant cells have a large membrane-bound space in which water, waste products, and nutrients can be stored. This space is called the
vacuole
One difference between prokaryotics and eukaryotics is that
procaryotes do not have a nucleus
Photosynthesis takes place in the __________ of plant cells
chloroplasts
Both plant cells animal cells have cell membranes. In addition, plant cells are surrounded by a(n)
cell wall
The meshlike network of protein fibers that supports the shape of a cell is called the
cytoskeleton
Rough endoplasmic reticulum has _____________ embedded on its surface
rbibosomes
Describe the movement of proteins through the internal membrane system of a cell
Proteins are made by ribosomes on the surface of the rough endoplasmic reticulum. Once made, proteins move from the ribosomes to the endoplasmic reticulum where they are transported through the cell. Portions of the endoplasmic reticulum containing proteins pinch off forming vesicles. Vesicles containing newly made proteins move through the cytoplasm to the Golgi apparatus. The Golgi apparatus membrane repackaging the mdified proteins. These new vesicles move to the cell membrane where the modified proteins are released outside the cell,
Explain the difference between cillia and flagellium
Cillia is short hairlike structures, Flagellum is long
What are three structure all cells have?
DNA, Cytoplasm, Cell membrane
Explain the function of any two organelles that he animal cell has.
mitochondria: Powerhouse converts energy into ATP
lysosomes: use digestive enzymes to remove waste from the cell
What is unique about the scanning tunneling microscope?
It can see living organisms
Compare and contrast prokaryotes and eukaryotes
Prokaryotes: have a cell wall, no nucleus, no organelles

Eukaryotic cells: have nucleus and organelles
