Biology Cast Review

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water, and releasing oxygen as a byproduct.

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

How are photosynthesis and cellular respiration interrelated?

Back

Photosynthesis uses the products (carbon dioxide and water) of cellular respiration, and cellular respiration uses the products (glucose and oxygen) of photosynthesis.

Front

What organelle is responsible for breaking down waste and cellular debris?

Back

Lysosomes are organelles that contain enzymes to break down waste materials and cellular debris.

Front

What are nucleic acids?

Back

Nucleic acids are biomolecules essential for all forms of life, primarily DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), which store and transmit genetic information.

Front

What is a hypertonic solution?

Back

A hypertonic solution is one that has a higher concentration of solutes compared to another solution, leading to the movement of water out of cells, causing them to shrink.

Front

What distinguishes prokaryotic cells from eukaryotic cells?

Back

Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do.

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

What is the role of catalase in cells?

Back

Catalase is an enzyme that catalyzes the decomposition of hydrogen peroxide into water and oxygen, protecting cells from oxidative damage.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
