Fundamentals of Biology

Front

What is a nucleus?

Back

The nucleus is a membrane-bound organelle found in eukaryotic cells that contains the cell's genetic material (DNA) and controls cellular activities.

Front

Are all prokaryotes unicellular?

Back

No, not all prokaryotes are unicellular. Some prokaryotes can form multicellular structures.

Front

What are the products of cellular respiration?

Back

The products of cellular respiration are Carbon Dioxide, Energy (ATP), and Water.

Front

What is the ratio of Carbon, Hydrogen, and Oxygen in carbohydrates?

Back

The ratio of Carbon, Hydrogen, and Oxygen in carbohydrates is 1:2:1.

Front

What type of cells are plant and animal cells?

Back

Plant and animal cells are examples of eukaryotic cells.

Front

What is the main difference between prokaryotic and eukaryotic cells?

Back

The main difference is that eukaryotic cells have a nucleus and membrane-bound organelles, while prokaryotic cells do not.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What are ribosomes?

Back

Ribosomes are cellular structures that synthesize proteins by translating messenger RNA (mRNA).

Front

What is the function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and structural support.

Front

What is DNA?

Back

DNA (deoxyribonucleic acid) is the molecule that carries the genetic instructions for life.
