Case Study Questions on Nutrition in Plants
Questions
Question 1:
Read the given passage below and answer the question:
Carnivorous plant is especially adapted for capturing and digesting insects and other animals by means of ingenious pitfalls and traps. There are more than 600 known species of carnivorous plants. The apparent trapping mechanism, which is always a modified leaf is a distinctive feature to these plants. The pitcher plant is an example of a carnivorous plant. The leaf of the Pitcher plant is modified into pitcher like structure to trap the insects. The apex of the leaf acts like a lid which can open and close the mouth of the pitcher.
Q.1. Insect eating carnivorous plants are also called ________plant.
(a) autotrophic
(b) saprophytic
(c) insectivorous
(d) symbiotic
Difficulty Level: Easy
Ans. Option (c) is correct.
Explanation: Carnivorous plants eat insects for their food requirements, so they are called insectivorous plants.
Q.2. One of the most important nutrients a pitcher plant need from insects is:
(a) Carbon dioxide
(b) Nitrogen
(c) Water
(d) Oxygen
Difficulty Level: Easy
Ans. Option (b) is correct.
Explanation: Pitcher plants grow in soil that is deficient in nitrogen content so they feed on insects to obtain the nitrogen.
Q.3. Consider the following statements about the Pitcher plant:
(A) It is a parasite.
(B) The leaves are green in colour.
(C) The hair present inside the lid is directed downward.
(D) Digestive juice is secreted in the apex of the leaf. The correct statements are:
(a) (A) and (B)
(b) (B) and (C)
(c) (C) and (D)
(d) (A), (B) and (D)
Difficulty Level: Difficult
Ans. Option (b) is correct.
Explanation: Pitcher plant is not a parasite. The plants are grouped under carnivorous plants as they feed upon insects.
The digestive juices secreted in the pitcher, the modified part of leaf.
Q.4. What type of mode of nutrition is found in pitcher plants?
Difficulty Level: Difficult
Ans. The pitcher plants have chlorophyll so they perform photosynthesis to produce their own food however, they grow in soil that lacks nitrogen content so, they feed on insects to obtain the nitrogen needed for their growth. Hence, they have both autotrophic as well as a partial heterotrophic mode of nutrition.
Q.5. How does a pitcher plant catch insects? (Medium)
Difficulty Level: Medium
Ans. When the insects land in the pitcher its lid closes and the insects are trapped and entangled into the hair. Digestive juices are secreted in the pitcher so the insects get digested and nutrients get absorbed.
