NEET BIOLOGY

Detailed explanation-1: -Solution: In the embryos of a typical dicot and a grass (monocot ), true homologous structures are cotyledons and scutellum. This is because in the monocots such as the grass family a single cotyledon is present which is called scutellum.

Detailed explanation-2: -So, the correct answer is ‘Cotyledons and scutellum. ‘

Detailed explanation-3: -Dicots (left) have two cotyledons. Monocots, such as corn (right), have one cotyledon, called the scutellum, which channels nutrition to the growing embryo. Both monocot and dicot embryos have a plumule that forms the leaves, a hypocotyl that forms the stem, and a radicle that forms the root.

Detailed explanation-4: -Answer: Inside the dicot seed lies a rudimentary stage known as the dicot embryo. Two broad cotyledons make up this plant. On either side of the major axis, there are two cotyledons. Answer: Cotyledons, cotyledons, and cotyledons are the three main elements of a dicot seed embryo.

Detailed explanation-5: -From this it is concluded that the cotyledons of monocots and dicots are not homologous. In addition, dissimilarity of cotyledons and succeeding leaves in dicots, together with recent genetic studies, suggests that the two cotyledons of dicots are not homologous with the succeeding leaves of the same plant.
