7th- Chapter 2 PreTest

What must organisms be able to obtain in order to survive?

• energy and heat

• DNA and water

• heat and cold

• energy and raw materials

When particles travel from an area of high concentration to an area of low concentration, it is called

• endocytosis

• active transport

• exocytosis

• diffusion

Diffusion allows materials to

• move in and out of cells.

• grow larger.

• get rid of large particles.

• produce energy.

A cell does not need to use energy during

• active transport.

• exocytosis.

• diffusion.

• endocytosis.

When water diffuses into or out of a cell, it is called

• exocytosis.

• osmosis.

• endocytosis.

• flooding.

Osmosis is important to cells because

• cells contain fluids that are mostly water.

• cells are filled with fluids that are mostly sugar.

• cells need to be kept cool.

• cells need food.

Passive transport occurs when small particles move from

• outside a cell to inside a cell.

• areas of lower concentration to areas of higher concentration.

• areas of higher concentration to areas of lower concentration.

• inside a cell to outside a cell.

A cell moving particles with the use of energy is called

• active transport

• osmosis

• passive transport

• endocytosis

The process by which plants, algae, and some bacteria use carbon dioxide, sunlight, and water to make glucose and oxygen is called

• osmosis.

• fermentation.

• photosynthesis.

• cellular respiration.

Why does a plant need to produce glucose?

• in order to turn green

• in order to obtain energy

• in order to move

• in order to get sunlight
