Theme : The World of the Living
Unit II : Organization in the Living World (45 Periods)
Call – Basic Unit of life : Cell as a basic unit of life; prokaryotic and eukaryotic
cells, multicellular organisms; cell membrane and cell wall, cell organelles and
cell inclusions; chloroplast, mitochondria, vacuoles, endoplasmic reticulum, Golgi
apparatus; nucleus, chromosomes – basic structure, number.
Tissues, Organs, Organ System, Organism : Structure and functions of animal and
plant tissues (only four types of tissues in animals; Meristematic and Permanent
tissues in plants).
Biological Diversity : Diversity of plants and animals – basic issues in scientific
naming, basis of classification. Hierarchy of categories / groups, Major groups of plants (salient features) (Bacteria, Thallophyta, Bryophyta, Pteridophyta,
Gymnosperms and Angiosperms). Major groups of animals (salient features) (Non-
chordates upto phyla and chordates upto classes).
Health and Diseases : Health and its failure. Infectious and Non-infectious diseases,
their causes and manifestation. Diseases caused by microbes (Virus, Bacteria and
Protozoans) and their prevention; Principles of treatment and prevention. Pulse
Theme : Natural Resources : Balance in Nature
Unit IV : Our Environment (15 Periods)
Physical resources : Air, Water, Soil. Air for respiration, for combustion, for
moderating temperatures; movements of air and its role in bringing rains across
Air, Water and Soil pollution (brief introduction). Holes in ozone layer and the
Bio-geo chemical cycles in nature : Water, Oxygen, Carbon and Nitrogen.
Theme : Food
Unit V : Food Production (10 Periods)
Plant and animal breeding and selection for quality improvement and management;
Use of fertilizers and manures; Protection from pests and diseases; Organic farming.
PRACTICALS (30 Periods)
Praticals should be conducted alongside the concepts taught in theory classes.
(List of Experiments in Biology)
- Preparation of stained temporary mounts of (a) onion peel, (b) human cheek cells
& to record observations and draw their labeled diagrams.
- Identification of Parenchyma, Collenchyma and Sclerenchyma tissues in plants,
striped, smooth and cardiac muscle fibers and nerve cells in animals from prepared
slides. Drawing of their labeled diagrams.

with male or female cone) and an Angiospermic plant. Drawing and providing two
identifying features of the groups they belong to.
- Observing the given pictures / charts / models of earthworm, cockroach, bony fish
and bird. For each organism, drawing of their picture and recording :
a) one specific feature of its phylum.
b) one adaptive feature with reference to its habitat.
- Study of the external features of root, stem, leaf and flower of monocot and dicot
