Answer / guest
Seeds that possess a special food storage tissue called the
endosperm are said to be albuminous and those which have no
such tissue for storage are said to be exalbuminous or
non-endospermic.
In albuminous seeds food is being stored in
endosperm the cotyledons are small and thin while on
exalbuminous seeds cotylesdon store up food and become thick
and Fleshy. When germination of seed takes place then food
is used by embryo whether it is stored in endosperm or in
cotypedon
Germination :-It is the process by which the dormant embryo
wakes up an begins to grow.
It is of two types
(1) Epigeal Germination
(2) Hypogeal Germination
(1)Epigeal:- In this cotyledons are seen upward by rapid
elongation of hypocotyl e.g. tamarind beans etc.
(2)Hypogeal :- When the cotyledons are seen to remain in
the soil, and in this epicoty the above the cotyledons and
elongates and pushes the plumule upwards.
