Biology Fall Semester Final Review

Front

What are the benefits of photosynthesis for animals?

Back

Provides oxygen and glucose for food.

Front

What is the main difference between passive and active transport?

Back

Active transport requires energy, passive does not.

Front

What happens to a cell placed in a hypertonic solution like saltwater?

Back

The cell shrinks because the water moves towards the salt.

Front

What is the main function of the vacuole in plant cells?

Back

Storage of nutrients and waste products.

Front

What is the monomer of carbohydrates?

Back

Simple Sugars (Monosaccharides).

Front

Define photosynthesis.

Back

The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs sunlight and converts it into chemical energy.

Front

Explain the difference between diffusion and osmosis.

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration; osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is a cell membrane's primary function?

Back

To protect the cell and regulate what enters and exits.

Front

What are the two types of cells?

Back

Prokaryotic (without a nucleus) and Eukaryotic (with a nucleus).
