A teacher describes a cell part that holds the genetic information and directs the cell's activities. What is that part called?

A teacher describes a plant cell part that captures energy from light so the cell can make its own food. What is that part called?

A student points to the mitochondria on a cell model and is asked what they do. What is the best answer?

A student points to a chloroplast on a plant cell model and is asked what it does. What is the best answer?

A student points to the cell membrane on a cell model and is asked what it does. What is the best answer?

A student points to the cell wall on a plant cell model and is asked what it does. What is the best answer?

Under a microscope, a class sees many small green structures inside the cells of an Elodea leaf. What are those green structures?

Onion cells under a microscope look like stiff boxes packed in rows instead of soft blobs. Which part gives each cell that stiff box outline?

Muscle cells in a runner's legs have many more mitochondria than skin cells do. What is the best explanation?

Oxygen moves into a cell and waste moves out of it. Which part of the cell controls that movement?

A cell's genetic information is damaged, so the cell can no longer be directed properly. Which part held that information?

Every cell, whether it comes from a plant or an animal, is surrounded by one thin, flexible boundary. What is that boundary called?

Both a plant cell and an animal cell need to release energy from food. Which part does that job in both kinds of cell?

A plant cell has a stiff layer just outside its cell membrane. An animal cell has no such layer. What is that stiff layer called?

A leaf cell and a human skin cell both store their genetic information in the same kind of part. What is that part called?

Sunlight strikes a leaf. Which cell part captures that light energy first so the plant can make food?

A bacterial cell keeps its genetic information loose in the cell instead of inside a nucleus. What name is given to a cell with no nucleus?

Plant cells and animal cells both keep their genetic information inside a nucleus. What name is given to cells built this way?

An amoeba carries out all of its life processes inside one single cell. What word describes an organism like this?

A maple tree is built from many different types of cells working together. What word describes an organism like this?

A pond plant uses its chloroplasts to make its own food from light energy. What word describes an organism that makes its own food?

A rabbit's cells contain no chloroplasts, so the rabbit must eat other living things to get food. What word describes an organism like this?

Cell theory answers the question of where new cells come from. What does it say their source is?

Cell theory says that every living thing is made of one or more of the same basic units. What are those basic units called?

Ana says a plant cell has no need for mitochondria because it already has chloroplasts. What is the correct statement?

A student says plant cells and animal cells have exactly the same parts. Which two parts does a plant cell have that an animal cell does not?

A student says every living thing is big enough to see without a microscope. Which of these organisms is made of only one cell?

Under a microscope, a student sees cells that each have a nucleus but no cell wall and no chloroplasts. Which sample did they most likely come from?

A student thinks only plants with leaves can make their own food. Which of these organisms also makes its own food from light?

A student adds stain to onion skin cells, and one dark, round spot shows up inside each cell. Which part is that spot?

Mushrooms make their own food from sunlight.

In a plant cell, the cell membrane lies just inside the cell wall.

Chloroplasts are found in animal cells.

An amoeba is made of only one cell, so it has no nucleus.

A bacterial cell has a cell membrane even though it has no nucleus.

Cell theory says the cell is the basic unit of structure and function in living things.
