Main Parts Of Plant: 1. Roots 2. Stem 3. Leaves 4. Flowers 5. Seed
Below Ground = Roots Above Ground = Shoot

Chapter 13: Plant Structure And Transport
The Functions of the Main Parts:
1. The Root: Anchor the plant Take in water (osmosis)
and minerals (active transport)
Store Food

2. The Stem: To hold up the parts of
the plant Main function is to
transport substances: To carry water and
minerals To carry food

Vascular Tissue (Transport): 1. Xylem:
Carries water and nutrients UP the plant FROM THE ROOTS to the leaves (capillary action)
2. Phloem: Carries food FROM THE
LEAVES to all parts of the plant

3. The Leaves: Photosynthesis Exchange of Oxygen and
Carbon Dioxide (stomata)
Loss of water vapour (evaporate/transpiration)

Transpiration: Transpiration is the loss
of water vapour from the surface of a plant
Trees get water from the roots to the leaves via this process

5. The Seed :
small embryonic plant enclosed in a covering called the seed coat, usually with some stored food
