Illustration] Indusium hood-shaped, fixed centrally behind the sorus and arching over it, soon withering, often illusive.
His observations bear on the development of the sorus and sporangium, but he dismissed the microsporangia as abortive or imperfectly developed structures.
The soruswas regarded as a sort of compound fruit, the sporangium as a carpel, the annulus as its midrib, and the spores as the seeds.
Each sorus contains many minute bodies known as spores, not unlike very miniature seeds in general appearance, but quite unlike them in behavior and mode of life.
Indusium of a few broad segments, at first covering the sorus completely.
Sori linear, confluent in pairs, each pair appearing like a singlesorus with a double indusium opening down the middle.

The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "sorus" in a variety of sentences. We hope that you will now be able to make sentences using this word.
