Biology Guides SS 2 Organization of Life – Classification of Plants
THEME – ORGANIZATION OF LIFE
TOPIC – CLASSIFICATION OF PLANTS
1. Spirogyra, liver-warts, mosses, maize, orange and hibicus.
2. Maize, rice, groundnuts, beans, yam, cassava, tomato, okra, banana, pawpaw, coffee, ginger, pepper, coconut, palm fruit.
3. Rice, beans, maize, cabbage, radish, ginger, mango, coconut.
By the end of the lesson, students should be able to:
1. classify plants using
a) botanical and
(b) agricultural techniques of classification
2. classify plants based on life cycles
CONTENTS OF THE LESSON
1. Botanical classification:
- Spermatophytes (the seed bearing plant)
2. Agricultural classification:
- cereals – maize, rice, etc.
- legumes – cowpea, groundnuts, etc.
- root crops – cassava, yam, etc.
- vegetables- tomato, okra, onion, etc.
- fruit – banana, pawpaw, etc.
- beverages and drugs – coffee, tobacco, etc.
- spices – ginger, pepper, etc.
- oil – coconut, palm fruit, etc.
- latex – natural rubber, etc.
- fibres – jute, cotton, etc.
3. Plants classified on the span of their life cycles:
1. Revises classification in SS 1 using specimens like spirogyra, mosses, water ferns, maize, orange and hibiscus.
2. Leads students to classify the specimens using agricultural classification.
3. Asks students to select from the specimens and name the classes they belong to based on life cycles.
1. Classify the specimens according to botanical classification.
2. Classify the crops using agricultural classification.
3. Classify the crops into annuals, biennials and perennials.
1. record in their notebooks the phyla of the specimens presented.
2. mention two examples of plants (crops) in each classification or category.
3. write the two examples each of annuals, bi-annual and perennials.
