- Transport in plants 1
- Why do plants need a transport system?
- Plants have a high requirement for mineral ions and water.
- What is a plants transport system?
- Specialised vascular bundles - consisting of the xylem and phloem
- Xylem : water and soluble mineral ions (upwards)
- Phloem : assimilates (up and down)
- Specialised vascular bundles - consisting of the xylem and phloem
- Diclotydenous plants have two seed leaves and a branching pattern of veins
- Where is the vascular bundle located?
- Center of a young root
- Xylem is in the middle in an 'X' shape
- Phloem is found in-between the corners of the 'X'
- Surrounding this is the epidermis
- Surrounding that is the meristem cells called the pericycle
- Surrounding this is the medulla
- Surrounding that is the meristem cells called the pericycle
- Surrounding this is the epidermis
- Phloem is found in-between the corners of the 'X'
- Provides strength to the plant
- Xylem is in the middle in an 'X' shape
- Center of a young root
- In wood plants, the vascular bundle separates and forms rings as it gets older : provides strength and flexibility
- In non wood plants, the vascular bundle separates and becomes discrete
- Vascular bundles form in the outermost area of plants in the veins and midribs of leaves
- In each vein, the xylem is on top of the phloem
- Vascular bundles form in the outermost area of plants in the veins and midribs of leaves
- In non wood plants, the vascular bundle separates and becomes discrete
- In the transverse section of a vascular bundle, the outermost layer is the Collenchyma
- Then there is the cortex
- Then there is the vascular bundle which consists of the phloem being the outermost, the sclerenchyma in the middle and the xylem being the innermost
- the space which the vascular bundles lie in is the medulla
- Then there is the vascular bundle which consists of the phloem being the outermost, the sclerenchyma in the middle and the xylem being the innermost
- Then there is the cortex
