Biology Semester 1 Finals Review

Front

What is a controlled variable?

Back

The condition kept constant so as not to confuse results.

Front

What products of photosynthesis are starting materials for cellular respiration?

Back

Glucose and oxygen.

Front

What is a hypotonic solution?

Back

A solution where the concentration of solutes is lower outside the cell than inside, causing water to enter the cell.

Front

What is diffusion?

Back

The process where solutes move from an area of high concentration to an area of low concentration.

Front

What is the role of ATP in cellular processes?

Back

ATP is the energy currency of the cell, transferring energy stored in glucose.

Front

What is osmosis?

Back

The movement of water across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is active transport?

Back

The process of moving molecules against their concentration gradient, requiring energy.

Front

What is the difference between photosynthesis and respiration?

Back

Photosynthesis converts light energy into chemical energy (glucose), while respiration breaks down glucose to release energy.

Front

What is a hypertonic solution?

Back

A solution where the concentration of solutes is higher outside the cell than inside, causing water to leave the cell.

Front

What is cellular respiration?

Back

The process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.
