cell structure
What is the name of the structure that controls what enters and leaves the cell?
Plasma membrane
Does a prokaryotic cell have a nucleus?
No.
What structure contains the genetic material in a eukaryotic cell?
Nucleus
A cell needs to control which substances enter and leave. Which structure performs this function?
Plasma membrane
What structure is the site of protein synthesis?
Ribosome
Which structure is found in both prokaryotic and eukaryotic cells and is responsible for protein synthesis?
Ribosomes
Name TWO membrane-bound organelles found in eukaryotic cells.
mitochondria, ER, Golgi apparatus, lysosomes, chloroplasts, etc.
A cell needs to make large amounts of protein. Which structure is directly responsible for protein synthesis?
Ribosomes
Name the organelle responsible for most aerobic ATP production in eukaryotic cells.
Mitochondrion
What type of ribosomes are found in prokaryotic cells?
70S ribosomes
What is the main advantage of having membrane-bound organelles?
They create separate compartments where different cellular processes can occur efficiently.
A cell has a very high energy demand. Which organelle would you expect it to contain many of?
Mitochondria
Which organelle modifies, sorts and packages proteins for transport?
Golgi apparatus
A student observes a cell with a nucleoid, 70S ribosomes and a cell wall. Is it more likely to be prokaryotic or eukaryotic? Explain.
Prokaryotic. It has a nucleoid rather than a membrane-bound nucleus and has 70S ribosomes.
Which type of cell would you expect to contain chloroplasts: a bacterial cell, animal cell, or plant cell?
Plant cell.
what are 2 functions of lysosomes?
break down food and old organelles
This organelle contains hydrolytic enzymes and is involved in intracellular digestion.
Lysosome
A bacterium has a plasma membrane, cell wall, ribosomes and circular DNA. It does NOT have mitochondria. A student concludes that it cannot carry out respiration. Is the student correct? explain.
No. Prokaryotes can carry out cellular respiration even though they don't have mitochondria. The plasma membrane is involved in the processes associated with respiration.
A cell contains a nucleus, mitochondria, Golgi apparatus and rough ER. Is it prokaryotic or eukaryotic? What evidence supports your answer?
Eukaryotic, because it contains membrane-bound organelles, including a nucleus.
what is a vacuole?
inner structure of a plant cell that helps keep its shape
