Conducting tissue vascular tissue
* Most vascular tissue carries nutrients
  - connects veins
  - is surrounded by layers
* Some vascular tissue carries water.
* Some vascular tissue fills bone cavities
  - conducting tissue type
* Vascular tissue connects leaf veins
  - consists of a continuous cylinder of secondary xylem with few resin canals
  - includes xylem, phloem, parenchyma, and cambium cells
* Vascular tissue is an adaptation to multicellularity and life on land
  - arranged as discrete collateral bundles
  - composed of xylem and phloem
  - essentially the veins and arteries of plants
  - found just near the nectary
  - internal conducting tissue for the movement of water, minerals, and food
  - involved with the transport of material
  - part of vascular plants
  - plant tissue
  - specialized tissue that conducts water and nutrients throughout the plant
  - tube like structures that carries water and food to the rest of the plant
  - lignified tissue in plants for conducting water, minerals and sugars
  - occurs in long strands called vascular bundles
  - provides long distance transport and structural support
  - refers to blood vessels
  - transports food, water, hormones and minerals within the plant
  - tissues allow for the transport of materials between roots and shoots
* Vascular tissues are in radial arrangement
  - seen as long strands and are called vascular bundles
  - specialized for water and nutrient transport
  - arise from a thread of dividing cells that by differentiation
  - form a vascular cylinder arranged as a central column
  - mark a lineage that gave rise to most modern plants

### conducting tissue vascular tissue:

Cambium
* are part of periosteums
  - stratums
  - the cells responsible for the growth of the stem and roots of a plant
* causes increase in diameter of the stem with passage of time.
* is the growing part of the tree trunk
* occurs between the xylem and phloem.
* produces new wood on the inside and new bark on the outside.

Midvein
* are prominent and covered in hairs.
* is vascular tissue

### conducting tissue vascular tissue:

Tracheid
* are cells that are specialized for transporting solutions around a plant
  - closed tubes with pits along their length
  - dead at maturity and have lignin in their secondary walls
  - elongated cells, closed at both ends
  - formed from superimposed cells with oblique perforated end walls
  - highly elongated cells with overlapping end walls
* are long and relatively narrow, and transport materials from the roots upward
  - tapered, with angled end-plates that connect cell to cell
  - cells with tapered, overlapping ends
  - thin cells
  - long, thin, tapered cells having lignin-hardened secondary walls with pits
  - spindle-shaped cells with pits through which water flows from cell to cell
* are the cells that make up the wood in the formative cambium layer
  - chief water-conducting elements in gymnosperms and seedless vascular plants
* are xylem and phloem
  - cells with thick secondary cell walls that are lignified
* conduct water cells in the plant.
* have obliquely-angled endwalls cut across by bars
  - thick secondary cell walls and are tapered at the ends
* look often square in cross-section, the lignified secondary wall is relatively thin.
