Biology Question on morphology of flowering plants
Which of the following is not always present in monocotyledonous seeds?
A
Scutellum
B
Epiblast
C
Coleoptile
D
Perisperm
Answer
Perisperm
Explanation
Solution
A monocotyledonous seed has a single cotyledon known as scutellum whereas epiblast represents rudiments of second cotyledon. It has shoot apex and few leaf primordia enclosed in a hollow foliar structure called coleoptile whereas radicle and root cap are enclosed in a sheath called coleorhiza. Perisperm is the remnant of nucellus in seed. It is often dry and nonfunctional. It is present in only few monocot and dicot seeds.
