NEETBotanyMorphology of Flowering Plants
Read the following statements regarding seed structures: (A) Scutellum is the large and shield-shaped cotyledon found in the seeds of grasses. (B) Epiblast represents the persistent endosperm in mature seeds. (C) Perisperm is the residual, persistent nucellus found in seeds like black pepper. (D) Groundnut and pea are examples of albuminous seeds. How many of the above statements are correct?
Options
- AOnly one
- BOnly three
- CAll four
- DOnly two
Correct answer
D. Only two
Step-by-step solution
Statement (A) is correct as the single cotyledon of monocots (like grasses) is called the scutellum. Statement (B) is incorrect because the epiblast is a rudimentary second cotyledon present in some grass embryos, not persistent endosperm. Statement (C) is correct as the residual, persistent nucellus in seeds like black pepper and beet is called perisperm. Statement (D) is incorrect because groundnut and pea are non-albuminous (non-endospermic) seeds, as their endosperm is completely consumed during embryo developm
