if sporangia is formed by more than a single cel, i.e a group of cells, it is called eusporangiate... eg. there are many ferns..ophioglossus is the most cited example... endoploidy means ploidy of more than germ cells inside an organism i.e in a organism's tissue... u can say that it is doubling of chromosome number in somatic cell... and glucans are nothing but polymers of glucose that too D glucose. like cellulose(beta-D-glucose) is a glucan and even glycogen( @-D-Glucose) is a glucan.. coz these are made only of glucose units.. u must have heard of arabans and xylans too.. these are also like glucans.. only units differ...

endoploidy refers to cells and organisms of certain somatic tissues within an organism having a higher ploidy than the germline cells of the organism, e.g. liver cells in humans and leaf mesophyll cells in plants
