What is the function of vacuoles in plant cells?

Back

Vacuoles are responsible for storage and release of macromolecules and cellular waste products. In plants, they also aid in maintaining turgor pressure.

Front

What is endocytosis?

Back

Endocytosis is the process by which cells take in materials by engulfing them, often through mechanisms like phagocytosis or pinocytosis.

Front

What is exocytosis?

Back

Exocytosis is the process by which cells expel materials, packaging them in vesicles that fuse with the cell membrane.

Front

What is the difference between rough ER and smooth ER?

Back

Rough ER is involved in protein synthesis and has ribosomes on its surface, while smooth ER is involved in lipid synthesis and detoxification.

Front

How does water movement occur in cells with different solute concentrations?

Back

Water moves from areas of lower solute concentration to areas of higher solute concentration, following the principle of osmosis.

Front

Where does ATP synthesis occur in cellular respiration?

Back

ATP synthesis occurs in the cristae of the mitochondria during cellular respiration.

Front

What is the role of lysosomes in a cell?

Back

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

Front

What is the primary function of the endoplasmic reticulum?

Back

The endoplasmic reticulum (ER) is involved in the synthesis of proteins and lipids, and it also plays a role in detoxification.

Front

What is the significance of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis and protecting the cell's internal environment.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, as they generate ATP through cellular respiration.
