Differences between Algae and Fungi on the basis of modes of nutrition:
| Algae | Fungi |
|---|---|
| They have chlorophyll. Thus, they can prepare their own food via photosynthesis. | Due to absence of chlorophyll, they do not prepare their own food. They mostly live on dead, decaying organic matter. |
Chapter 1: Classification of Plants — ICSE Class VII Biology Notes
Complete ICSE Class VII Biology study guide on Classification of Plants covering all five divisions from Thallophyta to Angiosperms. Learn the differences between monocots and dicots, understand vascular and non-vascular plants, and master plant division features with examples.
Key Concepts and Topics
Topics covered: Thallophyta, Bryophyta, Pteridophyta, Gymnosperms, Angiosperms, Monocots, Dicots
Weightage: Approximately 8 marks in the exam
Important Points to Remember
- Five divisions of plant kingdom from simplest to most complex
- Thallophyta: no true roots/stems/leaves, simple thallus body
- Bryophyta: amphibians of plant world, need water for reproduction
- Pteridophyta: first plants with vascular tissue, reproduce by spores
- Gymnosperms: naked seeds in cones, needle-like leaves
- Angiosperms: flowering plants, seeds in fruits, most diverse group
- Monocots vs Dicots: cotyledons, venation, roots, flower parts
Frequently Asked Questions
Q: What are the five divisions of the plant kingdom?
A: Thallophyta, Bryophyta, Pteridophyta, Gymnosperms, and Angiosperms.
Q: Why are bryophytes called amphibians of the plant world?
A: Because they live on land but need water for reproduction, just like amphibians.
Q: How are monocots different from dicots?
A: Monocots have one cotyledon, parallel leaf veins, and fibrous roots. Dicots have two cotyledons, reticulate veins, and tap roots.
