Classification — Classification is a system of arranging living organisms into groups based on their similarities and differences.
Binary fission — In a full-grown Amoeba, first the nucleus divides into two, and then the rest of the cell divides in a way that each half gets one daughter nucleus. This process is called binary fission.
Pseudopodia — Pseudopodia (meaning false feet) is the organ of locomotion in an amoeba.
Symbiosis — Symbiosis refers to a close and long-term interaction between two different types of organisms. For example, Rhizobium bacteria lives in the root nodules of leguminous plants. These bacteria provide food to the host plant and the host plant in turn provides shelter to the bacteria.
Mycelium — A network of hyphae is called mycelium.
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.
Exam Preparation Tips
- Focus on understanding concepts rather than rote memorization
- Practice drawing and labelling diagrams regularly
