Syllabus For BS Botany Semester 3rd
Introduction
Bot 401: Phycology and Bryology is a core subject of BS Botany that deals with the scientific study of algae (Phycology) and bryophytes (Bryology). This course builds a strong foundation for understanding lower plants, their structure, reproduction, classification, ecological role, and economic importance.
This subject is extremely important for:
- University exams
- Competitive exams
- Research in plant sciences
- Teaching & academic careers
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
- Chlorophyta (Green Algae) – Chlamydomonas, Spirogyra
- Phaeophyta (Brown Algae) – Sargassum, Laminaria
- Rhodophyta (Red Algae) – Polysiphonia, Gelidium
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
- Hepaticopsida (Liverworts) – Marchantia
- Anthocerotopsida (Hornworts) – Anthoceros
- 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
✔ Bryophytes: morphology, anatomy, alternation of generations
