Give reasons:
$(a)$ Animals of phylum Platyhelminthes are called flatworms.
$(b)$ Bryophytes are called amphibians of the plant kingdom.
$(c)$ Fungi are called saprophytes.
$(d)$ Bacteria and tapeworms are very different in their body design.
$(e)$ Plants like Pinus and deodar are called gymnosperms.

(N/A) They are called flatworms because their body is dorsiventrally flattened,meaning they are flattened from the top to the bottom.
$(b)$ Bryophytes are called amphibians of the plant kingdom because they live on land but require water for the process of fertilisation,as their male gametes need water to reach the female gametes.
$(c)$ Fungi are called saprophytes because they obtain their nutrition from dead and decaying organic matter by secreting digestive enzymes outside their body and absorbing the resulting soluble nutrients.
$(d)$ Bacteria are unicellular prokaryotic organisms with a simple cellular structure,whereas tapeworms are multicellular eukaryotic organisms with complex organ-system level body organization,reflecting different evolutionary paths and adaptations.
$(e)$ Plants like Pinus and deodar are called gymnosperms because they bear naked seeds that are not enclosed within a fruit.
