2 External Structure of the Plant – Parts of the plant on the outside. The Root  Types of Root Systems  Functions of the Root System  Specialized Root Systems

3 MAIN ROOT LATERAL OR SIDE ROOT ROOT SYSTEM LEAF STEM FLOWER FRUIT NODE NODE INTER- NODE TERMINAL BUDAXILLARY BUD SHOOT SYSTEM

4 The Shoot System is found ground and the Root System is found ground. ABOVE BELOW or UNDER

5 Looks like a tangled mass of roots Examples of plants With this root system are  Banana  Coconut  Rice  Corn  Sugar Cane All Grasses

6 Have a large main central root Have many branching roots Go deep in the soil Examples of plants : Large trees e.g. mango, avocado Shrubs e.g. tomato, peppers

7 Plant attaches itself to tree branch or telephone wire Roots hang down in mid-air and absorb water from rainfall Examples : Wild Pine Some Orchids

8 STILT ROOTS e.g. Mangrove

9 PROP ROOTS e.g. Corn

10 ADVENTITIOUS Roots - Grow from unusual places on plants such as - Stems, leaves and even fruits

11 Roots : - anchor plants firmly in the ground - absorb water and minerals from the soil - of some plants, can store starch - of some plants can be used to grow a new plant
