  1. Oil paper test

  2. Starch

  3. Calcium sulphate solution

  4. Iodine solution
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Some plants and animal produce oil. Oil paper test is a test used to detect oil in plant and animal products. It include a process in which a paper is moved back and forth few times against the substance and the presence of oil on the paper is checked.
So the correct answer is 'Oil paper test'.

Which of the following helps in nutrient conservation?

  1. Leaching

  2. Mineralisation

  3. Nitrification

  4. Immobilisation
Reveal answer Fill a bubble to check yourself
B,C Correct answer
Explanation

A.Leaching - the loss of water-soluble plant nutrients from the soil. It does not help in nutrient conservation.

B.Mineralisation – The process of formation of minerals from the organic compounds is called mineralisation. It helps in nutrient conservation.

C.Nitrification – Formation of nitrites or nitrates from ammonia or nitrogenous compounds is called Nitrification. It also helps in nutrient conservation.

D. Immobilisation – elements, cannot be transported from one place to another place in the body is called Immobilisation and the elements are called Immobilised elements.

So, the correct option is ‘Mineralisation or Nitrification’.

Along with all other nutrients, the body also needs an adequate supply of water.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The human body can last weeks without food, but only days without water. The body is made up of 50 to 75 per cent water. Water forms the basis of blood, digestive juices, urine and perspiration, and is contained in lean muscle, fat and bones. It helps to maintain the temperature of the body.

So, the correct option is 'True'.

Leaves appear green because they reflect green color from light spectrum. The part in the leaf that is responsible for the reflection is

  1. Inner membrane of Chloroplast

  2. Thylakoid space

  3. Thylakoid membrane

  4. Stroma
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Chloroplasts are green because they contain the green pigment chlorophyll in their thylakoid membranes. Chlorophyll is a pigment that absorbs red and blue light. So plants are green because chlorophyll reflects green light. 

So, the correct option is 'thylakoid membrane'.

Which of the following statements is false regarding the experiment carried out for photosynthesis?

  1. The two leaves experiment proved that photosynthesis took place only in the green part of the leaf which is exposed to sunlight

  2. Half leaf experiment indicate that co2 is required for photosynthesis

  3. In half experiment some part of leaf is inserted in a test tube having soaked cotton

  4. Starch is formed in a leaf
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Variegated leaves have green parts (where the cells contain chlorophyll) and white parts (where there is no chlorophyll). Only the parts that were green become blue/black with iodine solution, showing the importance of chlorophyll in photosynthesis. The parts without chlorophyll do not photosynthesize, and so they do not make starch and the iodine does not change colour.
So the correct option is 'The two leaves experiment proved that photosynthesis took place only in the green part of the leaf which is exposed to sunlight'.

  1. Waste matters

  2. Organic Nutrients

  3. Inorganic Nutrients

  4. Solid waste
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Eutrophication, the excessive growth of algae, is primarily caused by the influx of inorganic nutrients like nitrates and phosphates into water bodies.
