Cell Scenarios Practice

An amoeba cell is unique in that it is designed to move around.  Because of this, it needs to turn food (usually sugar) into energy.  What organelle would you expect to be VERY plentiful in amoeba cells so that it can make a lot of ATP?

• vacuole

• nucleus

• mitochondria

• chloroplast

A cell from the leaf of a cactus is green, which indicates the cells in it contain chlorophyll, a chemical that can turn light energy into food.  This chemical is stored in an organelle that is VERY plentiful in the leaf cell.  What are these organelles?

• vacuole

• nucleus

• mitochondria

• chloroplast

When you water a plant, it tends to “perk up” or stand a little taller.  This is because plant cells have an organelle designed to store water and other things for later use.  What organelle would be plentiful in plants and used for this purpose?

• vacuole

• nucleus

• mitochondria

• chloroplast

Onion cells are plant cells, but they are not green.  This means they do not contain any of a certain kind of organelle.  Because they are plant cells, however, they look kind of rectangular.  What organelle is missing in onion cells?

• vacuole

• nucleus

• mitochondria

• chloroplast

Onion cells are plant cells, but they are not green because they do not make sugar.  Because they are plant cells, however, they look kind of rectangular.  What organelle gives onion cells their boxy shape?

• cell membrane

• nucleus

• cell wall

• chloroplast

White blood cells are especially active when you are sick because their primary job is to fight off infections – often bacteria or viruses that do not belong in you.  Once they locate the invader making you sick, they eat it and destroy it.  What organelle do you think is plentiful in white blood cells?

• lysosomes

• cell membrane

• nucleus

• mitochondria

Your skin is a protective sheet that surrounds you on the outside.  Likewise, when your skin cells are cut open, your protective layer is broken down.  What part of your skin cells is punctured when you have a cut?

• lysosomes

• cell membrane

• nucleus

• mitochondria

Human red blood cells are interesting because they are made in your bone marrow. They are not made through mitosis by other cells. They are missing the control center of the cell and DNA. What organelle is missing from red blood cells?

• lysosomes

• cell membrane

• nucleus

• mitochondria

Look at the picture. What process? Why is it important?

• Mitosis is important because it removes waste.

• MItosis is important because it makes new cells.

• Osmosis is important because it makes new cells.

• Osmosis is important because it allows water to enter and leave the cell.

Look at the cell. What type of cell is it, and how do you know?

• It is a plant cell because only plant cells have a cell wall and chloroplasts.

• It is a plant cell because only plant cells have a nucleus and cell membrane.

• It is an animal cell because only animal cells have a nucleus and cell membrane.

• It is an animal cell because only animal cells have mitochondria and a nucleus.
