Tissues
Tissues are groups of similar cells performing specific functions, with plants and animals having different types adapted to their needs.
Core concept
Plant tissues include meristematic tissue (for growth), xylem (water transport), phloem (food transport), and parenchyma (storage and photosynthesis).
How it works
Animal tissues include epithelial tissue (covering and protection), connective tissue (support), muscle tissue (movement), and nervous tissue (signalling).
Why it matters
Each tissue type has cells specialised for its specific function, showing how cellular specialisation supports the organism's overall needs.
Key detail
Understanding tissues helps us see how organs and organ systems are built from specialised cells working together.
