Front

What is a eukaryote?

Back

A eukaryote is an organism whose cells contain a nucleus and other organelles enclosed within membranes. Examples include plants, animals, fungi, and protists.

Front

What is the function of the cell wall in plant cells?

Back

The cell wall provides structural support and protection to the cell, maintaining its shape and preventing excessive water uptake.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are organelles that conduct photosynthesis, converting light energy into chemical energy stored in glucose.

Front

What is the difference between chromoplasts and leucoplasts?

Back

Chromoplasts are colored plastids that store pigments, while leucoplasts are colorless plastids that store starches and oils.

Front

What is the primary stain used for observing starch in plant cells?

Back

Iodine is the primary stain used to observe starch in plant cells, turning blue-black in the presence of starch.

Front

What is the function of the nucleus in eukaryotic cells?

Back

The nucleus houses the cell's genetic material (DNA) and controls cellular activities by regulating gene expression.

Front

What is cytoplasm?

Back

Cytoplasm is the jelly-like substance within a cell that contains organelles, enzymes, and other components necessary for cellular processes.

Front

What is the function of the cell membrane?

Back

The cell membrane regulates the movement of substances in and out of the cell, providing protection and maintaining homeostasis.

Front

What are the main differences between plant and animal cells?

Back

Plant cells have a cell wall, chloroplasts, and large central vacuoles, while animal cells have centrioles and lysosomes.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are the sites of protein synthesis, translating messenger RNA (mRNA) into polypeptide chains.
