3 and 4vm statement is true
The true statement is - 1) In all plants, root system is developed from the radicle. and 4) The primary roots and its branches constitute the tap root system, as found in the Mustard plant.
Roots arise from radicles in plants while stem arises from hypocotyl and leaves arise from epicotyl. From seed, plant embryo develops and radicle of the embryo develops into roots.
Primary root is called taproot and it is branched. This root system, with a taproot and its branches, is a tap root system, which is found in the mustard plant.
Majority of flowering plants possess above-ground stems. Photosynthesis is mainly carried out by leaves and not only. In some plants, stems also possess chlorophyll and they carry out photosynthesis.
