Plant Structure and Transport
Transcript of Plant Structure and Transport
There are many plant types!
Structure of a typical flowering plant
Can you label its parts ?
anchor and support
absorb water and minerals
some store food
Supports and holds up leaves & flowers
Transports water , minerals and food
Some store food
potential growth point. Here new leaves or flowers may develop
Where plant makes its food
Allows gas exchange
Allows water vapour to pass out of the plant
Some store food
Produce seeds for reproduction
Transport in Flowering plants
1. Water Transport
Transported by the
Stomata allow water evaporation
Transpiration : loss of water vapour from a plant
Stoma = 1 pore
Stomata = 2+ pores
Tiny openings found on the lower surface of leaves.
Diagram on page 92, what is happening ?
Water is drawn out from the leaf into the air and it pulls a column of water up through the tubes, stem and roots.
To replace this water, plant absorbs water from the soil through the roots.
Nitrogen, phosphorus , potassium
dissolved in water soil
needed for plant to grow
3. Food Transport
some passed from leaves to other parts of plant.
2 types involved in plant transport
from the leaves around the plant
Transports water and dissolved minerals
To show the transport of water through a plant
To show that water is taken in from the roots and passes up and out of plant
To show that water evaporates from the surface of a leaf by transpiration
Venus Fly Trap
The Dancing Plant
The Corpse Flower
True or false?
1. The stem supports and holds up the leaves and flowers
Petals produce seeds
Stems and roots can store food
Transpiration is the gain of water
7.The stomata are pores found on the upper surface of the leaf
5. Xylem transports water
6. Phloem transports minerals
