Question

Which of the following represents category class
A. Angiospermae
B. Dicotyledons
C. Diptera
D. Hominidae

Answer 1

Hint: Group of one or more related orders is known as class. For example, the order Rodentia of rats, Primata of monkeys, gorilla, gibbon, and carnivo of cats and dogs are all placed in the same class Mammalia. All these orders were kept under the same class.

Complete answer:
Angiosperms are those plants in which seeds are formed inside the fruit and the sporophylls are organized into flowers. Angiosperms are divided into two classes on the basis of the number of embryonic leaves or cotyledons: the dicotyledons and the monocotyledons. The two are commonly spoken as dicots and monocots respectively. Dicots are flowering plants that are characterized by the presence of two cotyledons in the seed for example Pea, Rose, Mustard. Dicotyledonae is a class of plants that have two cotyledons.
So, the correct option is (B).
-Diptera is an order that contains true flies.
-Hominidae is a superfamily that comes under order Primates. Humans and their closest relatives, chimpanzees are both primates.
Additional Information:
Monocots are angiosperm or flowering plants that are characterized by the presence of a single cotyledon in the seed. For example, bananas, cereals, palms, orchids, etc.
Characteristics of dicot
1. Presence of two embryonic leaves is present.
2. Presence of cambium in the root. Cambium develops at the time of the secondary root.
3. The pith of the dicot root is small and inconspicuous.
4. In dicot stem pith and medullary rays are present.

Note: The higher classification of dicotyledons and monocotyledons is flowering plants. By studying the venation of plants we can differentiate plants into monocot or dicot. Leaves that have parallel venation are monocot and the plant with reticulate venation is a dicot.
