Question

Compare the reproductive organs and reproduction of selaginella ,equisetum and pteris

Answer 1

Answer:

selaginella is belongs to a class LYCOPSIDA which is a part of pteridophyta.

in lycopsida sporangia are formed on sporphylls. these are present on the tip of the plant . the group is called strobilus or cone.

equisetum or pipe is  is belongs to a class SPHENOPSIDA which is a part of pteridophyta.in SPHENOPSIDA sporangia are formed on sporphylls. these are present on the apical part of the aerial stem . the group is called strobilus or cone.

pteris belong to PTEROPSIDA . each and every leaf contain sporangia at the time of reproduction. but they do not have cones

hope you undrstand please mark as brainliest.

Answer 2

Reproductive organs and Reproduction

Explanation:

Selaginella  

• Selaginella is a reproduced sexually and sporophytic plant(2x)
• These spores are produced in microsporangia and megasporangia, separately which, thus, are delivered on fertile leaves known as megasporophylls and microsporophylls  

Equisetum  

• The gametophytic plant body bears sex organs for example antheridium (male) and archegonium (female)
• The gametophyte are fundamentally promiscuous (homothallic) i.e. they bear both male and female sex organs  

Pteris  

• Pteris is Spore-Producing Organ
• Pteris is a homosporous fern
• The sporangia of Pteris structure a ceaseless straight sorus along the edge, thus the distinction of sori is lost
