1. Plant systems

2. Learning goals
We are learning the functions two main systems of a plant.
We are learning the functions of stems, leaves and flowers of a plant.

3. Plant systems 2 Main systems: Root system
Shoot system (stem, leaves, flowers)

4. General Root functions
Anchorage
Absorption of water and nutrients
Storage

5. Root growth gravitropism roots grow positively towards gravity
due to expansion of cells at elongation zone

6. General Shoot functions
support
photosynthesis
reproduction

7. Shoot – stem functions support branches, leaves, and flowers
transports substances between roots and leaves
negative gravitropism – move away from gravity
positive phototropism – towards light

8. Shoot – leaf functions Photosynthetic – produces own food
Gas exchange – CO2 in & O2 out
Temperature regulation – transpiration
Designed to capture maximum light and minimize water loss
Support, protection, reproduction and attraction

9. Shoot – flower functions
Developed for sexual reproduction
Pollen produced on anther ‘fertilizes’ ovule to form a seed
