NEETBotanyMorphology of Flowering Plants
Read the following statements regarding the morphology of a typical cereal seed and choose the incorrect statement.
Options
- AThe seed coat is membranous and generally fused with the fruit wall.
- BThe endosperm is bulky and stores food.
- CThe plumule and radicle are enclosed in sheaths called coleoptile and coleorhiza respectively.
- DThe outer covering of the endosperm separates the embryo by a starchy layer called the aleurone layer.
Correct answer
D. The outer covering of the endosperm separates the embryo by a starchy layer called the aleurone layer.
Step-by-step solution
In the seeds of cereals such as maize, the seed coat is membranous and generally fused with the fruit wall. The endosperm is bulky and stores food. The outer covering of the endosperm separates the embryo by a proteinous layer called the aleurone layer, not a starchy layer. The plumule and radicle are enclosed in sheaths called coleoptile and coleorhiza respectively. Therefore, the statement claiming the aleurone layer is starchy is incorrect. Answer: The outer covering of the endosperm separates the embryo by a st
