SSC Biology Chapter 2: Cells and Tissues of Organisms
- Cell Membrane: Thin, semi-permeable, selectively permeable membrane surrounding the cell.
- Cytoplasm: Jelly-like substance inside the cell membrane where many metabolic processes occur.
- Nucleus: Control center of the cell, contains most of the cell's genetic material (DNA).
- Mitochondria: Powerhouses of the cell, generate energy through cellular respiration.
- Endoplasmic Reticulum (ER): Network of membranous tubules and cisternae involved in transport and synthesis.
- Ribosomes: Small organelles found throughout the cytoplasm, responsible for protein synthesis.
