Each leaf of Cycas is supplied with

The correct answer is Two girdle and two direct traces

Explanation:

• Cycas is a genus of gymnosperms, which are seed-producing plants that do not form flowers or fruits.
• Each leaf of Cycas is supplied with vascular bundles, which are essential for the transport of water, nutrients, and photosynthates.
• Vascular bundles in Cycas leaves are categorized into girdle traces and direct traces. Girdle traces wrap around the base of the leaf, while direct traces go straight to the leaf.
• The leaf traces are scattered in the cortex.
• Usually there are 4 leaf traces:
  • 2 Direct traces - They originate from the vascular cylinder in front of the leaf base.
  • 2 Girdled traces - They originate from the vascular cylinder present opposite to the direct traces.
• All the traces proceed together but soon move in opposite directions.
• They enter the leaf base by going around or girdling around the vascular cylinder.
• The girdled leaf traces remain attached to other leaf traces in the cortex.
• As they enter the petiole, the leaf trace bundles subdivide to form several petiole bundles.
