Question

Trailer stem is found in
A.Basella
B.Portulaca
C.Boerhaavia
D.All of the above

Answer 1

Long and weak stems that trail on the ground are trailer stems. They are on the soil's surface. The trailer stem is present in all the plants mentioned. These are plants without rooting at the nodes, with a weak stem trailing on the ground. Some forms of trailer stem are: runner, stolon, sucker. They can be divided into trailers that are prostrate or procumbent and decumbent.

Complete answer:
-Basella: In Basella Procumbent type trailers stem found. In Basella the stem creeps on the ground totally. Basella alba is a short-lived, perennial climbing plant that produces stems up to 9 meters long that scramble for support across the ground and twine through other plants. Hence option A is correct.
-Portulaca: trailers of the Portulaca Decumbent type found in the Portulaca Branches, expand vertically upwards after developing horizontally for a certain length. Simple identification of this plant: the round green body of the cylinder, the fleshy stem with thick narrow leaves, are the fundamental characteristics of any succulent plant, especially the moss rose. Hence option B is correct.
-Boerhaavia: A diffuse trailer type found in Boerhaavia. In the four o'clock tribe, Boerhaavia diffusa is a flowering plant species commonly known as the punarnava red spiderling. Develop profusely in all directions in these divisions. Hence option C is correct.
So all options are correct.
Hence option D: All of the above is the correct answer.

Note: Trailers are prostrate plants that trail along the surface with weak, long, and slender stems and do not attempt to climb up any support. In being single plants which do not root from the nodes and thus do not form daughter plants, these are distinct from creepers.
