A
Monocot
B
Dicot
C
Hybrid
D
Perennial
Explanation: 

Detailed explanation-1: -Based on the number of cotyledons in a seed, it is further classified into the following types. It comprises a single cotyledon emerging from the seeds after seed germination. Paddy, wheat, coconut, garlic, and ginger are the best examples of monocotyledons. Monocotyledons are also known as monocots.

Detailed explanation-2: -Flowering plants, called angiosperms, have embryos within their seeds that form one or two cotyledons, also often referred to as “seed leaves”. Those with one cotyledon are known as monocotyledons or monocots. Monocots include daylilies, orchids, palms, bananas, pineapples, and corn.

Detailed explanation-3: -Monocotyledonous seeds are covered with a single seed cotyledon. The embryo of monocotyledons has a terminal cotyledon known as scutellum. The scutellum is called seed leaf.

Detailed explanation-4: -Germination in Monocots As the seed germinates, the radicle emerges and forms the first root. In epigeous monocots (such as onion), the single cotyledon will bend, forming a hook and emerge before the coleoptile (Figure 18.4.

Detailed explanation-5: -Monocotyledons are plants that flower or angiosperms holding single cotyledon or embryonic leaf seed. Monocotyledon is a tiny number of plant species with 60, 000 species of plants.
