muscle tissue, muscle cell, stomach
muscle cell, muscle tissue, stomach
stomach, muscle tissue, muscle cell
stomach, muscle cell, muscle tissue

plant cells
bacterial cells
animal cells
fungi cell
A number of scientists made contributions to cell theory. Which scientist used a light microscope to observe cells in a slice of cork?

A Cell is shown below: The cell is (A) because it (B).
A:prokaryotic; B: has a nucleus
A:prokaryotic; B: does not have a nucleus
A:eukaryotic; B: has a nucleus
A: eukaryotic; B: does not have a nucleus
Lysosomes are organelles that contain enzymes. Which of the following is a function of lysosomes?
Lysosomes build lipids, carbohydrates, and proteins.
Lysosomes package lipids, carbohydrates, and proteins.
Lysosomes break down lipids, carbohydrates, and proteins.
Lysosomes store lipids, carbohydrates, and proteins.
All cells contain cell membranes. Which of the following describes the composition of cell membranes?
Cell membranes are composed of carbohydrate chains, which allow all materials to enter and leave the cell.
Cell membranes are composed of cellulose, which provide rigidity for the cell.
Cell membranes are composed of cytoplasm, which allows proteins to be excreted by the cell.
Cell membranes are composed of lipid molecules, which provide a flexible structure.
Which organelles allows NON-WOODY plants to support heavy structures such as leaves and flowers?
the cell membranes because they regulate what enters and leaves the cells
the chloroplasts because they convert sunlight into chemical energy
the Golgi apparatus because it packages proteins for storage in the cells
the vacuoles because they are filled with fluid, which provide rigidity
In eukaryotic cells, a number of organelles allow the cell to produce and distribute proteins. Where are proteins modified, sorted, and packaged?
Golgi apparatus
rough endoplasmic reticulum
ribosomes
smooth endoplasmic reticulum
The model shows a substance (oxygen) crossing a cell membrane. Which description below describes the process best? (arrow is pointin into the cell)
The model shows the process of active transport because the solute particles are moving from an area of low concentration to an area of high concentration.
The model shows the process of facilitated diffusion because the soulte is moving through a protein channel.
The model shows the process of diffusion because solute particles are moving from an area of high concentration to an area of low concentration.
The model shows the process of osmosis because the solute particles are moving from an area of high concentration to an area of low concentration.
A cell is placed in an isotonic solution. How does the cell maintain homeostasis in this environment?
There is no movement of water molecules into or out of the cell because the concentrations of solute particles inside and outside the cell are the same.
Water will move across the cell membrane to the inside of the cell because the cell has a higher concentration of solute particles than the solution.
Water will move across the cell membrane to the outside of the cell because the solution has a higher concentration of solute particles than the cell.
Water will move across the cell membrane in both directions because the concentrations of solute particles inside and outside the cell are the same.
The illustration shows a model of the transport of solute particles from outside the cell to inside the cell. What type of cell transport is modeled?
Simple diffusion
Facilitated Diffusion
Osmosis
Active Transport
Which describes active transport, but not passive transport?
requires cellular energy
moves particles across the cell membrane
moves particles from high concentration to low concentration
particles diffuse directly through the lipid bilayer
Multicellular organisms contain organ systems. Which of the following BEST describes the organs in an organ system?
The organs in an organ system are made up of similar cells.
The organs in an organ system are made up of similar tissues.
The organs in an organ system work together to perform a specific function.
The organs in an organ system work together to perform all the functions a multicellular organism needs to maintain homeostasis.
A student is developing a model that shows the steps of protein synthesis. The model should include activities in which three structures?
ribosomes, rough endoplasmic reticulum, Golgi apparatus
nucleus, Golgi apparatus, mitochondria
mitochondria, rough endoplasmic reticulum, nucleus
Golgi apparatus, nucleus, lysosome
nucleus, cytoskeleton, cell membrane
Which of the following processes is directly controlled by the cell nucleus?
Osmosis because the nucleus has nuclear pores that allow water to move in and out of the cell.
Energy production because the nucleus contains mitochondria.
Waste removal because a steady stream of molecules moves out of the nucleus.
Protein synthesis because DNA in the nucleus contains the instructions for making proteins
Which of the following activities occurs in both prokaryotic cells and eukaryotic cells?
Proteins are assembled on ribosomes.
A large central vacuole stores DNA and RNA.
Mitochondria provide energy for cell processes.
Chloroplasts capture and transform the energy of sunlight.
The rough endoplasmic reticulum releases enzymes to break apart wastes
Maryland white oak trees make their own food. their cells contain structures that capture energy from the sun. What are these structures?
chloroplasts
nuclei
mitochondria
ribosomes
What tyoe of cell is show here?
Animal
Plant
Bacteria
Virus
Is the cell shown is (A), which means it's DNA is (B)
A: Prokaryote; B: Linear
A: Eukaryote; B: Linear

Some antibiotics work by punching holes into the bacteria's cell membrane. This works to kill be bacteria because....
the bacterias's cell membrane is still selectively permeable, and can still maintain homeostasis
the bacterias's cell membrane is no longer selectively permeable, but it still maintain homeostasis
the bacterias's cell membrane is still selectively permeable, but it can no longer maintain homeostasis
the bacterias's cell membrane is no longer selectively permeable,and can not longer maintain homeostasis
