ICSE Class 8 Biology, Unit 2: Reproduction in Plants and Animals
From the CISCE curriculum. 10 key concepts, about 5 days of study at 20 to 30 minutes a day.
What this unit aims at
Reproduction is one of the most important functions of living organisms. It is essential for perpetuation of species. There are two ways by which living organisms give rise to new organisms – Asexual (vegetative propagation) and sexual reproduction. While asexual reproduction involves a single individual parent, sexual reproduction involves two different individuals of different sexes, one male and another female. In this theme children will learn more about various methods of vegetative/asexual reproduction in plants and animals, a brief account of fertilization and post fertilization changes in flower and main organs of reproductive system of human male and female.
Your child should be able to
- record during a visit to garden the common names of plants and how they are multiplied
- observe and correlate butterflies and honeybees moving around flowers to the process of pollination
- ask the gardener how he raises or multiplies plants like jasmine, rose, Bryophyllum, Chrysanthemum, Dahlia, potato and money plant
- observe in a nursery how cuttings and budding methods of vegetative propagation are used for growing larger number of roses
- observe how grass plants which are planted at some distance from each other cover the entire soil after some days due to vegetative propagation
- recognize that sexual reproduction involves the fertilization of an egg cell by a sperm cell to produce offspring that may closely resemble the parents

Teach this unit at home
- A day-by-day plan from the CISCE concepts, so you know what to cover each day.
- A step-by-step script for each day, so you know what to say and ask (AI-written from the CISCE curriculum, so check it against your child's school book).
- A quiz at the end.
