A vacuole is a membrane-bound sac that plays a role in the storage and the release of cellular products. How do the vacuoles in animal cells differ from vacuoles in a plant cell?
Plant cell vacuoles are usually smaller because plants can make their own food.
Animal cells usually contain less vacuoles because they have an excretory system to eliminate waste.
Plant cell vacuoles are usually larger because they also provide structural support for the plant tissues.
Animal cell vacuoles are usually larger because they have to store a lot of glucose from the food they eat for later use

A team of scientists think they discovered a new organism while exploring Brazil. Upon bringing the specimen back to their lab in Atlanta, they observe the specimen for several weeks. They take a sample from the specimen to observe it under a microscope and see the sample is composed of many small compartments containing what appears to be nuclei. They shine a bright light to the left of the specimen and observe it slowly turn itself towards the light over multiple days.
What further evidence would support that the newly discovered specimen is alive?
The specimen appears to be breathing.
The specimen observed under the microscope contain various organelles.
When placed in pure water, the specimen seems to swell up, absorbing the water.
The specimen grows in size and develops colorful blooms over the several weeks in which it is being observed.
All living things are made up of one or more cells. Individual cells process all the characteristics of life as stand alone units. Although all living things do not move, they all respond to stimuli from their environment. Two students engaged in the following arguments that plant cells exhibit characteristics of life when they respond to stimuli in their environment.
Student A: After a rain shower, the vacuole (which stores water) in plant cells becomes larger and exerts more pressure in the cell because the plant cell gained water.
Student B: If there is no rain, the vacuole (which stores water) in plant cells becomes smaller and exerts less pressure in the cell because the plant cell uses the reserved water.
Which student has presented the best argument for a plant cell responding to stimuli in its environment?
Only the argument of Student A represents a plant’s response to stimuli in its environment.
Only the argument of Student B represents a plant’s response to stimuli in its environment.
Neither argument of Student A or Student B represents a plant’s response to stimuli in its environment.
Both arguments of Student A and Student B represent a plant’s response to stimuli in its environment.
Which structure in the diagram to the above indicates that this must be a plant cell? (Select ALL that apply!)
cell wall
cell membrane
chloroplasts
mitochondria
central/large vacuole
You are looking at cells under the microscope. You notice one type of cell has many more lysosomes than the others. Your teacher said white blood cells have lots of lysosomes. Why would the white blood cells have an abundance of lysosomes?
White blood cells have many lysosomes because they need lots of ATP to help carry oxygen.
White blood cells have many lysosomes because they need to produce lots of proteins to help build muscle.
White blood cells have many lysosomes because they need to produce a lot of glucose and oxygen.
White blood cells have many lysosomes because they need to destroy pathogens with digestive enzymes.
A student created the following models comparing plant and animal cells. What improvements should the student make to their models?
They need to remove the nucleus from model B because they do not need the organelles to convert materials into nutrients using sunlight.
They need to add mitochondria to both models because they both require energy production.
They need to remove the chloroplasts from model A because they do not need the organelles to convert materials into nutrients using sunlight.
They need to add a cell wall to model B for structure and support.
A child with cystic fibrosis has an mutated protein in his cells which does not behave normally. The mutated protein stops chloride ions from leaving the cells. This causes water to be retained in the cell creating thicker fluids. These fluids cause a buildup of mucus which leads to breathing problems. Which cell structure is most likely being negatively affected by the mutated protein?
The mutated protein is most affecting the cell membrane because the protein is causing water to be stored in the cell and water storage is a function of the cell membrane.
The mutated protein is most affecting the nucleus because the protein is preventing DNA production which is a function of the nucleus.
The mutated protein is most affecting the cell membrane because the protein is not allowing certain materials to leave the cell which is a function of the cell membrane.
The mutated protein is most affecting the ribosomes because the protein is causing the production of excess mucus which is a function of the ribosomes.
