The cell is composed of the cell membrane, cytoplasm, and nucleus containing DNA, with the membrane regulating material exchange, cytoplasm facilitating cellular functions, and the nucleus controlling cell activities. Organelles like ribosomes, endoplasmic reticulum, Golgi bodies, mitochondria, lysosomes, and vacuoles perform specific roles in protein synthesis, energy generation, waste disposal, and material storage within the cell.
Insights
- The cell is composed of three main parts: the cell membrane, cytoplasm, and nucleus (DNA). The cell membrane controls what enters and exits the cell, while the cytoplasm houses essential organelles and facilitates various cellular functions. The nucleus contains DNA, directing all cellular activities and serving as a blueprint for cell functions.
- Organelles like ribosomes, endoplasmic reticulum, Golgi bodies, mitochondria, lysosomes, and vacuoles each have specific roles within the cell, such as protein synthesis, energy production, waste digestion, and storage of substances. These organelles work together to ensure the cell's survival and proper functioning.
