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

Back

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

Front

What are Golgi bodies and what is their primary function in the cell?

Back

Golgi bodies, also known as the Golgi apparatus, are organelles that modify, sort, and package proteins and lipids for secretion or delivery to other organelles.

Front

Define cytoplasm and its role in the cell.

Back

Cytoplasm is the jelly-like substance that fills the interior of the cell, providing a medium for chemical reactions and housing organelles.

Front

What is the difference between plant and animal cells regarding cell structure?

Back

Plant cells have a cell wall and chloroplasts, while animal cells do not have a cell wall and have different organelles such as lysosomes.

Front

Explain the process of diffusion in cellular biology.

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration, resulting in the equal distribution of substances.

Front

What is the role of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis and protecting the cell's internal environment.

Front

What are chloroplasts and their function in plant cells?

Back

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

Front

Describe the function of ribosomes in the cell.

Back

Ribosomes are the sites of protein synthesis, where amino acids are assembled into proteins based on the instructions from mRNA.

Front

What is osmosis and how does it differ from diffusion?

Back

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

Front

What is the significance of the nucleus in a cell?

Back

The nucleus is the control center of the cell, containing the cell's genetic material (DNA) and regulating gene expression and cell division.
