What is Phycology?

Phycology is the branch of botany that deals with the study of algae.

Key Features of Algae

  • Mostly aquatic
  • Photosynthetic
  • Simple thalloid body
  • No true roots, stems, or leaves

Major Groups of Algae

Importance of Algae

  • Oxygen production 🌍
  • Food (seaweeds)
  • Agar, alginates & carrageenan
  • Biofertilizers
  • Research & biotechnology


What is Bryology?

Bryology is the study of bryophytes, commonly known as amphibians of plant kingdom.

Characteristics of Bryophytes

  • Grow in moist habitats
  • Lack vascular tissues
  • Dominant gametophyte
  • Require water for fertilization

Main Groups of Bryophytes

  1. Hepaticopsida (Liverworts)Marchantia
  2. Anthocerotopsida (Hornworts)Anthoceros
  3. Bryopsida (Mosses)Funaria, Polytrichum

Importance of Bryophytes

  • Soil formation
  • Prevention of soil erosion
  • Ecological indicators
  • Peat formation (Sphagnum)


Bot 401 Syllabus Overview

✔ Algae: structure, reproduction, life cycles
