Question

Culms are the plants with
(A) Erect stem
(B) Creeper stem
(C) Strong stem
(D) All of the above

Answer 1

It is derived from the Latin word 'culmus' which means 'stalk' and is known as the stem of any plant form. A culm is the stem of an aerial grass or sedge above ground. It is derived from culms and referred originally to the stem of any type of plant.

Complete answer: Culms are erect-stem plants. The existence of a joined stem called the culm characterizes grass and bamboo. The culms are usually hollow, although there are strong culms in some bamboo species. Each culm starts with a node and ends (solid joint). Internodes are considered the segments between nodes. Leaves and branches are grown from nodes. Example: For example, bamboo.
Typically, bamboos are fast-growing permanent species with some species growing up to 30 cm every day. Usually, the woody ringed stems, called culms, are hollow between the rings (nodes) and emerge from a thick rhizome in branching clusters (underground stem).
In the smallest species, bamboo culms can range in height from 10 to 15 cm (about 4 to 6 inches) to more than 40 metres (about 130 feet in height. Although the narrow leaves on young culms typically emerge directly from the stem rings, horizontal leaf-bearing branches frequently sprout from mature culms. The majority of bamboos bloom and bear seeds only after 12 – 120 years of growth and only once in their lifetime.
Hence, the correct answer is option A.

Note: It is also evident from the above discussion that the plants with erect stems are culms. The nodes and internodes were considered. From the nodes, leaves and branches emerge. Certain species are vigorously distributed and can form a dense soil, excluding other plants.
