Key differences to remember for diagrams and comparative questions:
The branch of biology that studies the structure, function, and chemistry of cells.
The cell is the basic structural and functional unit of all living organisms.
Forms the structural framework of the body. It includes rigid, mineralized bone (containing osteocytes) and flexible, resilient cartilage (containing chondrocytes).
Chromoplasts: Contain colored pigments (carotenoids, xanthophylls) that give vibrant colors to flowers and fruits to attract pollinators.
Cells bearing hair-like cilia on their free surface to move particles along (e.g., respiratory tract). 2. Connective Tissue
