Question: Dicot endospermic seed is
Options:
Castor
Fenugreek
Both (a) and (b)
Bean
-Dicot endospermic seeds are seeds of dicotyledonous plants (plants with two seed leaves) that retain a significant portion of their endosperm (nutritive tissue) even after the embryo has fully developed.
-Both Castor and Fenugreek are examples of dicot plants that have endospermic seeds.
🔑Key Points:
-After fertilization, the ovary develops into fruit and the ovules develop into the seeds.
✏️A seed consists of:
-Seed coat – It can be divided into the outer testa and inner tegmen.
-Embryo – It consists of the radicle, plumule, embryonal axis and cotyledon(s).
-Post fertilization, the endosperm develops along with the zygote.
-The primary function of endosperm is providing nutrition to the developing embryo.
-After the embryo matures, the endosperm may or may not be retained in mature seeds.
✏️Based on the above factor, seeds are divided into 2 groups:
-Endospermous – The endosperm is present in the mature seeds. Example – Maize, coffee, castor.
-Non-endospermous – The endosperm is not present in the mature seeds. Example – Pea, gram, beans.
-Monocots are usually endospermous with only a few exceptions.
-The endosperm in monocots is usually bulky and stores food.
