Cell Structure and Function Class 9

Front

What is the function of chloroplasts in plant cells?

Back

Chloroplasts convert light energy into chemical energy in the form of glucose through photosynthesis.

Front

What is the main difference between plant cells and animal cells?

Back

Plant cells have chloroplasts and a cell wall, while animal cells do not.

Front

What is cytoplasm?

Back

Cytoplasm is the jelly-like fluid inside a cell that contains organelles and is the site of many cellular processes.

Front

What organelle is responsible for energy production in cells?

Back

Mitochondria are responsible for producing energy (ATP) through cellular respiration.

Front

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

Back

The cell wall provides structure, support, and protection to the plant cell.

Front

What is the function of the nucleus in a cell?

Back

The nucleus contains the cell's genetic material (DNA) and controls cellular activities.

Front

What is the endoplasmic reticulum (ER)?

Back

The endoplasmic reticulum is a network of membranes involved in protein and lipid synthesis.

Front

What is the golgi complex?

Back

The golgi complex modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is the function of vacuoles in plant cells?

Back

Vacuoles store nutrients, waste products, and help maintain turgor pressure in plant cells.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are the sites of protein synthesis, translating messenger RNA into proteins.
