Question

What are the modes of nutrition for members of the kingdom monera?

Answer 1

These are the oldest, simplest and most numerous microorganisms.Their mode of nutrition is mainly absorptive, but some are photosynthetic or chemosynthetic. Although most of the bacteria in this division Eubacteriophyta are heterotrophic, there are some autotrophic species which produce ATP and glucose by oxidizing chemicals in their environment (chemosynthesis) or by utilizing light energy in thylakoid membranes (photosynthesis). Some of the photosynthetic species have pigments similar to chlorophyll a in higher plants, but they do not produce oxygen as a by-product of photosynthesis. The photosynthetic Eubacteriophyta include purple sulphur bacteria, purple nonsulphur bacteria, green sulphur bacteria and prochlorobacteria. The prochlorobacteria are quite distinct from other members of the Eubacteriophyta because they possess both chlorophylls a and b of higher plants. The prochlorobacteria also produce oxygen like the Division Cyanophyta, but unlike the cyanobacteria they do not have phycobilin accessary pigments. [It should be noted here that some biologists place the prochlorobacteria in the Division Cyanophyta.]

Answer 2

The mode of nutrition of organisms in this group can be either by synthesising their own food(autotrophic) or getting it by environment(heterotrophic).
