Cell Biology Concepts and Processes

Front

What organelle contains substances to break down and recycle cellular components?

Back

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

Front

Which cells are classified as eukaryotic?

Back

Eukaryotic cells include animals, plants, fungi, and protists.

Front

True or False: The light absorbed by chlorophyll powers the photosynthesis reaction in the chloroplast.

Back

True. Chlorophyll absorbs light energy, which is used in the process of photosynthesis.

Front

What macromolecule is described as fatty, waxy, or oily and does not dissolve in water?

Back

Lipids are macromolecules that are hydrophobic and include fats, oils, and waxes.

Front

What is the main function of the cell membrane?

Back

The cell membrane protects the inside of a cell from the external environment and regulates what enters and exits the cell.

Front

What is the function of mitochondria in a cell?

Back

Mitochondria are known as the powerhouse of the cell, as they produce energy in the form of ATP through cellular respiration.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are organelles that conduct photosynthesis, converting light energy into chemical energy in the form of glucose.

Front

Define prokaryotic cells.

Back

Prokaryotic cells are simple, single-celled organisms that lack a nucleus and membrane-bound organelles, such as bacteria.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis, translating messenger RNA into polypeptide chains.

Front

What are the building blocks of proteins?

Back

Amino acids are the building blocks of proteins, linked together by peptide bonds.
