Question

Linnaeus placed bacteria, fungi along with plants in Kingdom Plantae. The character that unified these diverse groups is the

• A. presence of cell membrane
• B. presence of cell wall
• C. similar mode of nutrition
• D. similar mode of reproduction by spores

Answer 1

The correct option is B presence of cell wall

One of the main characters that Linnaeus considered during classification was the presence or absence of a cell wall. Bacteria and fungi were placed along with plants because of the presence of cell walls.
Cell membrane is present in bacteria, fungi and plants.
Plants have an autotrophic mode of nutrition.
Bacteria and fungi have heterotrophic modes of nutrition.

Bacteria, fungi and plants produce spores but the mode of production of spores is different. Plants, like algae, produce zoospores during asexual reproduction. Bacteria produce endospores during unfavourable conditions. Fungi produce spores during both sexual and asexual reproduction.
