Biology Semester 1 Exam Review Part 1

Front

How does diffusion work?

Back

Solutes move from high concentration to low concentration.

Front

What is the difference between cilia and flagella?

Back

Cilia are small protrusions that are all around the cell, flagella are long protrusions generally from only one side of the cell.

Front

What is the primary function of the light reactions of photosynthesis?

Back

To produce NADPH and ATP.

Front

What is the purpose of the Golgi Apparatus?

Back

Packaging and Shipping of Materials.

Front

What supplies the electrons that are lost in PS I?

Back

The electrons from PS II.

Front

Define diffusion.

Back

The movement of solutes from an area of high concentration to an area of low concentration.

Front

What is osmosis?

Back

The diffusion of water across a semi-permeable membrane.

Front

What role do chloroplasts play in photosynthesis?

Back

Chloroplasts are the sites where photosynthesis occurs, converting light energy into chemical energy.

Front

What is the function of ribosomes?

Back

Ribosomes are responsible for protein synthesis.

Front

Explain the structure of the cell membrane.

Back

The cell membrane is composed of a phospholipid bilayer with embedded proteins, allowing selective permeability.
