New terms
- multicellular trichome tip (PO:0025535):
comment:
- plant cuticle ridge (PO:0025536): A portion of plant cuticle (PO:000022) that forms a ridge, may be overlayed with epicuticular wax (PO:0025388).
Comment: The plant cuticle ridges are mainly cutin (PO:0025385).
- adventitious shoot axis PO:0025534: A shoot axis (PO:00025029) that develops in an unusual place. develops from a bud (narrow synonym adventitious bud )
- plant sap (new PO:00255380): A portion of plant substance (PO:0025161) that is an aqueous solution which may contain sugars, hormones, mineral elements and/or other nutrients.
Comment: plant sap should not be confused with latex or resins.
- xylem sap (new PO:0025539): A plant sap (PO:0025538) that is an aqueous solution which may contain mineral elements, nutrients, and plant hormones, and is transported from the root system (PO:0025025) toward the leaves through the tracheary elements (PO:0000290) of the xylem.
Transport of sap in xylem is characterized by movement from the roots toward the leaves.
- phloem sap (new PO:0025539): A plant sap (new PO:0025538) that is an aqueous solution which may contain sugars, mineral elements, and plant hormones, and is transported through the phloem sieve elements (PO:0025406).
