Explanation / Answer
1) Difference of moncots and dicots
2) Some points of Asteraceae and Orchidaceae
3) Pollution by animas and fruits:
Pollination by fruits: In fruits the ovule develops in to a seed and ovary develops into fruit.
4)
Moncots Dicots Annual rings are not formed Annval rings are formed due to secondary thickness in the ground tissue the vascular bundles are scattered In dicots the vascular bundles are arranged in a ring Where as in cortex and pith there is no much distinction clear distinguish can be seen in cortex and pith Secondary thickening cannot be occur Secondary thickening can occur Vascular bundles are in large numbers Vascular bundles are in limited Between xylem and phloem no cambium is occur Between xylem and phloem occurs cambium
