Which instrument is best for viewing cells and cell parts?

A. glassesB. microscopeC. telescopeD. magnifying glass

What is the best description of a cell? They are

A. the smallest thing that scientists know about.

B. free-swimming animals that have cilia.

C. box shaped units that cork is made from.

D. the small units that all living things are made of.

How are all cells similar?

A. They perform the functions of life.B. They make food from sunshine, air

and water.C. They have the same parts as one

another.D. They can swim in water and find

their own food.

Using the following diagram of a cell to answer the next two

questions: Organelle X controls cell

functions.What have scientists named this

organelle?A. nucleusB. cytoplasmC. cell membraneD. cell wall

What substance is found at Y?

A. DNAB. cytoplasmC. membraneD. cell wall

Which part of the cell contains genetic materials?

A. cell membraneB. nucleusC. cytoplasmD. cell wall

What are the food-making structures in plant cells?

A. cell membraneB. nucleusC. cytoplasmD. chloroplasts

Which cell organelle do all cells have that controls the movement of materials into

and out of the cell?A. Cell wallB. Nuclear membraneC. NucleusD. Cell membrane 

Which organelles would you expect a plant cell to have but

not an animal cell?A. cell wall, chloroplastB. nucleus, cell membraneC. cytoplasm, diffusionD. osmosis, cell membrane 

Which diagram best represents a plant cell?

 

A. AB. BC. both D. neither

What is the function of the green circles in “B”?

A. get rid of cell waste productsB. control the entry of food into the cellC. use sunlight to make sugar D. control the activities of the cell

What is the difference between the outer covering of

“A” and “B”?

A. A has a shell like an egg, B is a soft membrane.

B. A has a cell membrane, B has a cell wallC. A and B both have cell walls that support the

organismD. A is covering a plant cell, B is covering an

animal cell

What is the process by which water moves across a cell

membrane called?A. osmosisB. active transportC. diffusionD. resolution

A cell is placed in pure water. What will happen to the cell

size?A. it will shrinkB. it will expand in sizeC. it will not changeD. it is impossible to predict    

The cells are separated by a membrane that allows water to pass through. How

will water move in this example?

 The dots represent sugar atoms. The rest of each cell is filled with water.

 

A BA. more will move from A to BB. move will move from B to AC. it will move equally back and forthD. it will not move

Why does the sugar stay in the cell?

A BA. it is dissolved in the waterB. it is connected to the nucleusC. it cannot pass through the membraneD. it is a solid made of crystals.

Why does osmosis occur? It happens because

A. gravity pulls all matter toward the center of Earth.

B. water moves from high concentrations to low.

C. cells are alive and only living things have osmosis.

D. cells are the smallest parts of living things.

How do cells get energy from food?

A. Cells break food into smaller parts, releasing energy.

B. Cells have electricity in the nucleus that travels to the rest of the cell.

C. Cells create energy because they are able to move.

D. The sun sends food through space that turns into energy.

What do cells do with waste products?

A. They store wastes in the cell membrane.

B. Wastes are passed out through the cell membrane.

C. Wastes are broken down into helpful substances.

D. The cells store the wastes, which allows them to grow.

Why are only plant cells able to produce food from sunlight?

Plant cellsA. have cell walls that tell the cell how

to produce food.B. have cytoplasm which creates and

stores food.C. have chloroplasts which is where

food is produced.D. have a cell wall to give the plant

support and strength.

Which is a plant cell, A or B?

A. Cell A because plant cells are not round.B. Cell A because plant cells have a cell wall that helps hold their shape.C. Cell B because the oblong structures in cell B look like chloroplasts.D. Neither is a plant cell. Plant cells do not have that maze-looking

structure.

What guides all cell processes?

A. genetic material in the nucleusB. energy from the mitochondriaC. movement through the cell

membrane

Which answer correctly identifies the 5 levels of cell

organization from simplest to most complex?

Which answer correctly identifies the 5 levels of cell organization in a dogs body

from simple to most complex?

A. bone cell, bone tissue, femur (thigh bone), skeleton, dog

B. dog, skeleton, femur, bone tissue, bone cell

C. skeleton, bone tissue, bone cell, dog, femur

D. bone tissue, bone cell, femur, skeleton, dog

Overlapping circles can be used to show relationships. In this diagram, levels of organization within living
