What to Focus On

  • Plant kingdom comprises multicellular, autotrophic organisms.
  • Plants probably arose from Chlorophyta.
  • Deep ocean photosynthetic organisms are restricted to about 200 metres depth.
  • Algae lack true roots, stems, leaves, or leaf-like organs.
  • Vegetative reproduction in algae is usually by fragmentation.
  • Zoospores are the most common asexual spores in algae and are flagellated.
  • r-phycoerythrin masks chlorophyll a in red algae.
  • Red algae are mostly marine, with Batrachospermum as a freshwater exception.
  • Red algae have no flagellated cells at any stage.

Common Mistakes to Avoid

Cyanobacteria are algae and belong to Plantae.

All algae are plants in the same way, so unicellular green algae must always be placed with higher plants.

Red algae are always marine, so any freshwater red alga must be impossible.

Red algae pigment and deep-water adaptation
