Question 1 Report
Which of the following performs similar functions?
Sorus and indusium perform similar functions. Sorus is a cluster of sporangia (structures that produce and contain spores) found on the underside of fern leaves. Indusium is a thin membrane-like structure that covers the sorus and helps to protect and disperse the spores. Both sorus and indusium are involved in the reproduction of ferns. Sorus produces the spores and indusium helps to protect and disperse them.
