all cells come from preexisting cells
What is one primary difference between a prokaryotic cell and a eukaryotic cell?
prokaryotic cells have a nucleus
eukaryotic cells have a nucleus
prokaryotic cells do not have cytoplasm
eukaryotic cells do not have cytoplasm
What are the two primary functions of the cell membrane?
packages materials and makes protein
allows for the movement of materials and forms a barrier
packages materials and makes lipids
stores genetic information and controls protein synthesis
What is the primary component of the cell membrane?
carbohydrates
phospholipids
proteins
nucleic acids
Which of the following is NOT a function of proteins that are embedded within the cell membrane?
they control the passage of materials
they act as receptors
they package materials
they help the cell maintain homeostasis
Which part of the phospholipid is polar?
the phosphate head group
the fatty acid tail
all of the phospholipid
none of the phospholipid
Which part of the phospholipid is nonpolar?
the fatty acid tail
the phosphate head group
all of the phospholipid
none of the phospholipid
What term is used to describe the cell membrane's ability to distinguish between different types of molecules, only allowing certain materials to pass through?
selective choice
selective movement
selective permeability
selective diffusion
What is diffusion?
the movement of molecules from an area of low concentration to an area of high concentration
the movement of molecules from an area of high concentration to an area of low concentration
the movement of materials in a vacuum
none of the above
Specialized structures that work together inside a cell are called?
nuclei
ribosomes
organelles
eukaryotes
Which sequence shows the progression from least complex structure to most complex structure?
cell ---> organ--->tissue--->organ system
cell ---> tissue--->organ--->organ system
organ system ---> organ--->tissue--->cell
organ---> cell--->tissue--->organ system
Compare and contrast the function of the rough endoplasmic reticulum and the smooth endoplasmic reticulum.
rough ER produces proteins, while smooth ER produces lipids
rough ER has no ribosomes, which smooth ER has ribosomes
rough ER produces lipids, while smooth ER produces proteins
rough ER stores genes, while smooth ER stores proteins
Which organelle contains cholorphyll, the pigment found in plant cells, responsible for absorbing sunlight?
ribosome
gogli apparatus
vacuole
chloroplast
What is the function of the ribosome?
stores genetic information
produces proteins
stores proteins
produces lipids
What is the function of the Golgi apparatus?
communicate with other cells
convert solar energy into chemical energy
process and deliver proteins
store genetic information
What is the function of the nucleus?
communicate with other cells
convert solar energy into chemical energy
process and deliver proteins
store genetic information
What is the function of the mitochondria?
energy conversion
stores genetic information
cell to cell communication
delivers proteins
What is the primary difference between passive and active transport?
passive transport requires energy
active transport requires energy
there is no difference between them
passive transport always requires protein channels
Why are passive and active transport important to a cell?
allows the cell to grow
allows the cell to maintain homeostasis
allows the cell to move
none of the above
Diffusion is an example of which type of transport?
passive transport
active transport
channel transport
all of the above
