From given statements with reference to the embryo, which of these are incorrect? a. A typical dicot embryo consists of an embryonal axis and 2 cotyledons. b. The portion of the embryonal axis above the level of cotyledons is hypocotyl. c. The protein below the level of cotyledons is epicotyl. d. The epicotyl terminates with the stem tip, and the hypocotyl terminates with the root tip.

Describe the stages of embryo development in a dicot plant.

Which of the given statements are true? (i) During the development of a dicot embryo, heartshaped embryo is followed by globular embryo. (ii) The part of embryonal axis above the level of cotyledons is epicotyl, while the part below the level of cotyledons is epicotyl, while the part below the level of cotyledons is hypocotyl. (iii) Monocot seeds possess a single cotyledon represented by scutellum.

Assertion : During embryo development in dicots, suspensor serves as the main nutritive tissue for the embryo. Reason : The last cell of the suspensor at the end adjacent to the embryo is known as haustorium.
