mitochondria
vacuole
ribosome
Which organelle would you expect to find in plant cells but not animal cells?
mitochondria
chloroplast
ribosome
smooth endoplasmic reticulum
Which of the following structures serve as the cell's boundary from its environment?
mitochondria
channel protein
chloroplast
Cell membrane
During diffusion, when the concentration of molecules on both sides of a membrane is the same, the molecules will
move across the membrane to the outside of the cell
stop moving across the membrane
continue to move across the membrane in both directions
move across the membrane to the inside of the cell
The diffusion of water across a selectively permeable membrane is called
osmotic pressure
osmosis
pinocytosis
active transport
Which term describes the relatively constant internal physical conditions of an organism?
cell specialization
organ system
homeostasis
unicellularity
A group of similar cells that perform a particular function is called
an organ
a tissue
an organ system
a division of labor
Electron microscopes can reveal details
only in specimens that are still alive
about the different colors of cell structures
of cell structures only once they are stained
1000 times smaller than those visible in light micrscopes
Which of the following is not found in the nucleus
mitochondria
nucleolus
chromatin
DNA
which organelle breaks down organelles that are no longer useful?
Golgi apparatus
lysosome
endoplasmic retiulum
mitochondrion
Which sequence correctly traces the path of a protein in the cell?
ribosome, endoplasmic reticulum, golgi apparatus
ribosome, endoplasmic reticulum, chloroplast
ribosome, golgi apparatus, endoplasmic reticulum
Which organelle converts the chemical energy stored in food into useable energy?
Chloroplast
golgi apparatus

mitochondrion
What is the following function of cell membrane ?
Breaks down lipids, carbohydrates, and proteins from food
stores water, salt, proteins, and carbohydrates
keeps the cell wall in place
regulates movement of materials in and out of the cell
The cell membrane contains channels and pumps that help move materials from one side to the other , what are the channels and pumps called?
carbohydrates
lipids
proteins
bilipids
Why does diffusion occur?
molecules are attracted to one another
molecules constantly move and collide with another
cellular energy forces molecules to collide
cellular energy pumps molecules across the membrane
The cells of unicellular organisms are...
Specialized to preform diff task
larger than those of multicellular organisms
Unable to respond to changes in their environment
Able to carry out all of the function necessary for life
