Question

explain the different types of seedson the basis of number of cotyledons

Answer 1

lowering plants are divided into two classes: Monocotyledones (monocots) and Dicotyledones (dicots). As the names imply, the main distinction is the number of cotyledons present in the seed embryo–1 or 2. There are several other differences:

Monocot                                                           Dicot

Petals in multiples of 3

                                                                     Petals in multiples of 4 or 5

Stamens in multiples of 3

                                                                         Stamens in multiples of 4 or 5

Parallel leaf veins

                                                                               Branching leaf veins

 

Fibrous roots

                                                                                       Taproot

Herbaceous

                                                               Herbaceous or woody

Examples of Both Monocots and Dicots

Monocots include most of the bulbing plants and grains, such as agapanthus, asparagus, bamboo, bananas, corn, daffodils, garlic, ginger, grass, lilies, onions, orchids, rice, sugarcane, tulips, and wheat.

Dicots include many of the most popularly grown garden flowers and vegetables, including legumes, the cabbage family, and the aster family, such as apples, beans, broccoli, carrots, cauliflower, cosmos, daisies, peaches, peppers, potatoes, roses, sweet pea, and tomatoes.

Answer 2
