Cell Structure and Investigation Mind Map
Types of Cells
Eukaryotic Cells (Animal, Plant, Fungi, Protists)
Nucleus present
Membrane-bound organelles
Complex structure
Prokaryotic Cells (Bacteria, Archaea)
No nucleus
Circular DNA
Small and simple structure
Cell Organelles and Their Functions
Nucleus – Controls cell activities, contains DNA
Mitochondria – Powerhouse of the cell, produces ATP
Ribosomes – Protein synthesis
Endoplasmic Reticulum (ER)
Rough ER – Protein transport (has ribosomes)
Smooth ER – Lipid synthesis, detoxification
Golgi Apparatus – Modifies, packages, and transports proteins
Lysosomes – Digests unwanted materials (in animal cells)
Vacuole – Stores nutrients and waste (large in plants, small in animals)
Chloroplasts – Photosynthesis (only in plant cells)
Cell Membrane – Controls entry and exit of substances
Cell Wall – Provides structure (only in plant cells)
Cell Investigation Techniques
Light Microscope
Magnifies up to 1500x
Used for live cells
Electron Microscope
Higher resolution (SEM for surface, TEM for internal structures)
Cell Staining
Increases contrast (e.g., iodine for plant cells, methylene blue for animal cells)
Cell Fractionation
Separates organelles by centrifugation
