Why are chloroplasts important in plants?
Chloroplasts are critical for photosynthesis, where plants convert solar energy into chemical energy stored in molecules of glucose.
What is the difference between rough and smooth endoplasmic reticulum?
Rough ER has ribosomes on its surface and is involved in protein synthesis, while smooth ER is involved in lipid synthesis and does not have ribosomes.
What role do ribosomes play in a cell?
Ribosomes are essential for protein synthesis. They read the genetic instructions to build proteins from amino acids.
How do mitochondria generate energy?
Mitochondria generate energy through the process of cellular respiration, converting nutrients into ATP, a molecule that powers cellular functions.
What is the main function of the nucleus in a cell?
