🔑 Key Concepts & Definitions

• Nucleus: The membrane-bound organelle in eukaryotic cells that contains the cell's genetic material (DNA). It acts as the control center of the cell, regulating gene expression and cell activities (Schleiden and Schwann, 1839).
• Cytoplasm: The gel-like substance filling the interior of the cell, surrounding the nucleus, and composed of cytosol, organelles, and cytoskeleton. It provides a medium for biochemical reactions and organelle movement (source).
• Plasma membrane: Also known as the cell membrane, it is a phospholipid bilayer with embedded proteins that surrounds the cell, controlling the exchange of substances between the cell and its environment (source).
• DNA in the nucleus: The genetic blueprint stored within the nucleus, composed of deoxyribonucleic acid (DNA). It carries the instructions necessary for cell function, replication, and protein synthesis (source).
• Chloroplast: An organelle found in plant cells and some algae, responsible for photosynthesis. It contains chlorophyll, which captures light energy to produce glucose (source).
• Cell wall: A rigid outer layer found in plant cells, fungi, and some bacteria,…
