Which statement BEST summarizes why the cell theory was developed over time?
As cells change, they proved the cell theory was inaccurate
The discovery of new evidence resulted in changes to the cell theory
Changes in cell models showed the cell theory was based on opinion
The cell theory was modified with the discovery of every new organelle
In the past, some scientists accepted the theory of spontaneous generation.
This theory states that organisms can arise from nonliving matter.
Currently, scientists use the cell theory to explain the origin and growth of new organisms.
Which of these statements is a key idea of cell theory and a rejection of spontaneous generation?
Cells are basic units of life
All living things are made of matter
All cells arise from pre-existing cells by division
All cells are formed from the combination of two cells
Plant cells have one central vacuole.
Which statement explains how the central vacuole supports the function of the plant cell?
A larger central vacuole has a larger membrane surface area, which increases the rate of production of ATP.
The large surface area of the central vacuole increases the production of necessary proteins needed for the cell.
The central vacuole stores the genetic material of the cell in a central location, allowing all organelles to function more effectively.
As the central vacuole expands with molecules needed for photosynthesis, it causes the cell to become more rigid and creates structural support to the plant
Which of the following BEST explains the purpose of the inner membrane
to prevent the mitochondria from folding in on itself
to provide a large surface area for the production of ATP
to provide a large surface area for the production of glucose
to protect the genetic information that is stored in the organelle
How is the location of the rough ER related to its overall purpose for the cell?
The rough ER is near the nucleus which holds the instructions that allow the ribosomes to make proteins.
By being closely attached to the smooth ER, the rough ER can easily sort, synthesize, and package lipids for the cell.
The rough ER is used as an extra layer of protection around the nucleus to prevent ribosomes from entering the nucleus.
Being close to the nucleus helps the rough ER receive better direction on producing energy in the form of ATP for the cell.
Which of the following statements correctly states the process shown in the diagram?
The process labeled 1 shows how cells can easily move molecules with the concentration gradient using high energy molecules.
The process labeled 2 shows how cells move molecules against the concentration gradient without needing high energy molecules.
The process labeled 3 shows how cells use ATP to facilitate the active transport of molecules against the concentration gradient.
All three processes show how molecules freely move in and out of the cell regardless of the concentration gradient or available energy.
Which characteristics are shared by all four cells?
genetic material and ribosomes
membrane-bound organelles and a cell wall
presence of a mitochondria and cell membrane
mechanism for transforming sunlight into energy and DNA
Which correctly identifies the two cells described in the table?
Both Cell 1 and Cell 2 are eukaryotic.
Both Cell 1 and Cell 2 are prokaryotic.
Cell 1 is eukaryotic and Cell 2 is prokaryotic.
Cell 1 is prokaryotic and Cell 2 is eukaryotic.
Which of the following completes this concept map?
Virus
Bacteria
Plant Cell
Animal Cell
A human sperm cell moves its flagella back and forth in order to move through its environment.
Which statement describes how this eukaryotic cell transfers energy to the flagellum in order to allow it to move?
The mitochondria is used in the cell to make the glucose needed to create ATP.
The cell uses the mitochondria to generate high energy proteins that move the flagella.
The cell mitochondria utilize cellular respiration to generate glucose that gives the flagella energy to move.
The cell produces ATP in the mitochondria and the breaking of high energy bonds are used to move the flagella.
What process is occurring in the image?
The production of sugar.
The production of mitochondria.
The storing of energy for use by the cell.
The releasing of energy for use by the cell.
Which part of cell theory best supports the ability to make that claim?
All living things are made of cells.
The basic unit of life has a nucleus.
All cells come from preexisting cells.
Cells are rapidly evolving to become more complex.
Which of the following best describes the type fo transport that is occurring?
Diffusion, because water is moving across the cell membrane going with the concentration gradient.
Osmosis, because water is moving across the cell membrane going with the concentration gradient.
Diffusion, because water is moving across the cell membrane going against the concentration gradient.
Osmosis, because water is moving across the cell membrane going against the concentration gradient.
