Question

In funaria ,20 chromosome are present in rhizoids,then the no. Of chromosome in calyptra,theca & foot will be ?

Answer 1

Plant body in funaria is gametophytic (n), therefore n = 20. Calyptra, theca and foot are the part of sporophytic (2n) body. Rhizoids have chromosome number 20 means n = 20. Therefore 2n = 40. So, calyptra, theca and foot have 2n = 40 or chromosome number is 40.
