Cell theory was first proposed in 1838. Evidence obtained through additional scientific investigations resulted in the current cell theory. Which statement describes a component of the original cell theory that was removed because of the new scientific knowledge?
All living things are made of cells.
All cells come from other preexisting cells.
Cells form through spontaneous generation.
Cells are the basic structural and functional units of life.
There are some similarities between prokaryotic and eukaryotic cells. Which of the following structures is found in both prokaryotic and eukaryotic cells?
lysosome
mitochondrion
nucleus
ribosome
Look at the cross section of a cell membrane of a eukaryotic cell. H+ ions are being pumped from a low concentration to a high concentration.
How do you describe this type of transport across the cell membrane?
active transport
passive transport
facilitated diffusion
co-transport
Which cell structure is correctly paired with its primary function?
ribosome - protein synthesis
mitochondrion - movement
vacuole - cell division
nucleus - storage of nutrients
A person with swollen gums rinses his mouth with warm salt water, and the swelling decreases. Which of the following has occurred?
The swollen gums have absorbed the saltwater solution.
The saltwater solution lowers the temperature of the water in the gums.
The salt in the solution has moved against the concentration gradient.
The water in the gums has moved out due to the high concentration of salt in the solution.
Joy took the notes shown below while learning about cells.
• Forms boundary between a cell and the outside environment
• Controls the movement of materials into and out of the cell
• Consists of double layer of phospholipids
She forgot to write the name of the cell structure that her class was studying that day. What structure is described in her notes?
endoplasmic reticulum
cell membrane
cell wall
nucleus
The cell membrane of the red blood cell will allow water, oxygen, and carbon dioxide to pass through. Because other substances are blocked from entering, this membrane is called
perforated
semi-permeable
non-conductive
permeable
Muscle cells are responsible for obtaining energy so the body can perform voluntary and involuntary movement. Using you knowledge about organelles and muscles, how would a muscle cell differ from other types of animal cells?
The muscle cell would have larger centrioles than the other types of animal cells.
The muscle cell would have more mitochondria than the other types of animal cells.
The muscle cell would have a larger golgi apparatus than other types of animal cells.
The muscle cell would have more endoplasmic reticulum than the other types of animal cells.
Cells can be classified into two different categories: prokaryotic and eukaryotic. Which of the following information is needed in order to determine if an organism is prokaryotic?
The organism’s color and mass.
The organism’s internal structures.
If the organism is unicellular or multicellular.
The methods the organism uses to feed and move.
In pure water, a red blood cell from an animal will swell and burst, but a leaf cell from a plant will not. Which structure in the leaf cell is responsible for this difference?
cell membrane
cell wall
mitochondrion
nucleus
