Answer: Option A. -> True
:
A
Pteridophytesare members ofcryptogams, which means they have inconspicuous reproductive organs. Hence, Pteridophytes neither have flowers nor they produce seeds. They have naked embryos that are called spores.

Answer: Option A. -> Monera
:
A
Prokaryotes are organisms which lack a well-defined nucleus and membrane-bound organelles. Monera is the only kingdom which contains prokaryotic organisms. Kingdom Monera includes bacteria, blue- green algae etc.

Answer: Option C. -> Protista
:
C
Kingdom Protista consists of different types of unicellular eukaryotic organisms. E.g. unicellular algae, diatoms, protozoans etc.
Most protists are unicellular, but there are some relatively simple multicellular forms also.

Answer: Option A. -> Thallophyta
:
A
∙ Thallophyta hasthe least tissue differentiation among all divisions of the Kingdom Plantae. This group of plants do not have specific parts like roots, stem, leaves and flower. Algae belong to this group. They are aquatic plants and reproduce through spores.
∙ Bryophytes are photosynthetic, non-vascular terrestrial plants.
∙ Pteridophytes are vascular plants (with xylem and phloem) that produces spores.
∙ Gymnosperms are group of vascular plants that do not have an outer covering or shell around their seeds. They do not produce flowers.
