Biology Unit 2 Review

Front

Diffusion & Facilitated Diffusion are both __________ transport.

Back

Passive transport is the movement of molecules across a cell membrane without the need for energy input.

Front

Which microscope delivers the highest overall magnification possible?

Back

The Transmission Electron Microscope (TEM) provides the highest overall magnification, allowing for detailed observation of cellular structures.

Front

Miller and Urey's Experiment tried to show:

Back

Chemicals in the right conditions could form the molecules necessary for life, demonstrating the potential for abiogenesis.

Front

What protects and supports plant cells?

Back

The cell wall is a rigid layer that provides structural support and protection to plant cells.

Front

What is the storage area for the cell?

Back

The vacuole is an organelle that stores nutrients, waste products, and helps maintain turgor pressure in plant cells.

Front

What is the function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis.

Front

What is the role of mitochondria in a cell?

Back

Mitochondria are known as the powerhouse of the cell, generating ATP through cellular respiration.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the primary function of chloroplasts?

Back

Chloroplasts are organelles in plant cells that conduct photosynthesis, converting light energy into chemical energy.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and organelles.
