• Flat circular organelle found in plant cells which is not present in animal cells

                 Plastids

• Three types of plastids

                 Chloroplasts, Leucoplasts, and Chromoplasts

• Site of Photosynthesis

                 Chloroplasts

• Plastids which give colors to flowers and leaves of plants

                 Chromoplasts

                 Curcumin

• Orange color of Carrot is due to

                 Carotene

• Red color of tomato is due to

                 Lycopine

• Light energy is converted into chemical energy in the presence of

                 Chloroplasts

• Element present in Chlorophyll

                 Magnesium

• White colored or colorless plastids are called

                 Leucoplasts

• Plant that does not contain chlorophyll

                 Fungi

• Author of Systema Naturae

                 Carl Linnaeus

• Organisms which prepare food their own are called as 

                 Autotrophs (Eg: Green plants)

• Organisms which cannot prepare food their own and is mainly dependent on green plants are  called as 

                 Heterotrophs

• Organisms which derive their food from dead and rotten materials are called as 

                 Saprophytes

• Examples of Saprophytes

                 Bacteria, mushrooms, yeast, bread mould etc

• Organisms that live on or inside other living organisms to derive their food are called

                 Parasites

• Authority which testifies the purity and quality of bottles of jiuce, squash, soap etc

                 Fruit Product Order (FPO)

• Examples of balanced diets

                 Milk, Soyabean

• Carbohydrates are made up of

                 Carbon, Hydrogen and Oxygen

• Ratio of Hydrogen and Oxygen in Carbohydrates

                 2:1

• Examples of Carbohydrates

                 Glucose, Cellulose, Sugar starch etc

• Major function of Carbohydrates

                 Production of energy

• Sources of Carbohydrates are

                 Rice, wheat, honey, sugar, potato, carrot etc

• In plants carbohydrate is stored as

                 Starch

• In animals carbohydrate is stored as

                 Glycogen

• Carbohydrate required for an adult person per day

                 400-500gm

• Sugar present in high concentration in liver

                 Glycogen

• Maximum starch content in rice is

                 70-80%

• basic unit of starch is

                 Glucose

• Deficiency of carbohydrate cause

                 Weight loss and tiredness
