Ruminate endosperm is commonly found in seeds of-
A. Annonaceae (Areca nut)
B. Crucifarae
C. Compositae
D. Euphorbiaceae

Explanation

Solution

Seeds are the reproductive outcome in plants. It can also be used as a reproductive medium to produce new offspring such as in pine trees. Seeds store food for the fruit in the plant. A seed is enclosed in a protective fleshy covering. It can be woody too but this covering can be determined as fruit. The flowering plants or fruit bearing plants are-gymnosperm and angiosperm plants.

Complete answer:
Seeds are the product of the ripened ovule after the fertilization process. The embryo is made from the zygote and the seed coat from the ovule integuments. So, as we discussed seed, let 's understand about ruminate endosperms. Ruminate endosperm in which the endosperm is dissected in growth of the seed coat. Ruminate endosperm forms when the seed coat intrudes inward via meristematic growth.
Ruminate endosperm is frequently present in the Annonaceae family seeds. Some of the examples of families are Rubiaceae, Aceraceae, Aristolochiaceae, Palmaceae. The testa of the seed coat gets infolded into the endosperm.
It is found in custard apple, berries, and syncarps. Seeds are one to many per pistil. They have a fleshy and usually brightly colored cover and they are oily. The ruminate endosperm is the nutritive tissue surrounding the embryo.

Therefore option A. is the correct answer

Note:
Ruminate endosperm is formed when the seed coat intrudes inward into young endosperm via meristematic growth. It is characterized by its uneven and enlarged surface.it can provide valuable taxonomic groups and evaluations to the family. Endosperm is the food required for the development and growth of the developing embryo.
