Question

Monocot characteristics are
A. Fibrous root system, parallel-veined leaves, trimerous flowers, and two cotyledons
B. Fibrous root system, parallel-veined leaves, trimerous flowers, and one cotyledon
C. Fibrous root system, reticulate veined leaves, trimerous flowers, and one cotyledon
D. Tap root system, parallel venation, trimerous flowers, and one cotyledon

Answer 1

Hint: The monocots are also known as monocotyledons. Monocots comprise mostly the bulbing plants and some grains, like agapanthus, onions, orchids, rice, asparagus, daffodils, garlic, ginger, grass, lilies, sugarcane, tulips, bamboo, bananas, corn, and wheat.

Complete answer:
The monocotyledons are generally denoted as the monocots. The monocots are a group of plants that mostly contain grass and grass-like flowering plants or angiosperms. The seeds of these plants generally contain a single embryonic leaf or only one cotyledon.
-Monocots make up one of the main groups of plants into which the angiosperms are divided conventionally. The remaining of the flowering plants contain two cotyledons and hence are placed in the category of dicotyledons, or dicots. Monocot plants, as the term indicates, contain a single cotyledon.
-These plants possess distinguishing features such as a fibrous root system as the radicle is short-lived, therefore it is replaced by numerous adventitious roots forming a network. These plants also contain parallel-veined leaves and have trimerous flowers.
-Trimerous flowers refer to those flowers which contain only three petals. These flowers are found in monocotyledonous plants.
The correct answer is option B.

Note: The most important difference between monocots and dicots is their growth pattern. The monocots lack a lateral meristem known as the cambium which allows the continual growth in diameter along with the growth in height also known as secondary growth. Even though the monocots are largely herbaceous but a few arboraceous monocots can attain tall height, great length, and more mass.
