Plant Kingdom
Question
Question 1 : What is the major difference between plant cell and an animal cell?
1. Cell wall
2. Cell membrane
3. Eukaryotic nature of cells
4. Genetic material
Answer
Correct Anaswer : 1
Explanation:
Plant cells contain an extra layer outside their cell membrane called cell wall. Cell wall plays a major role in the metabolic activities of a plant cell. It helps in controlling of osmotic pressure.

Question 2 : Artificial classification of plant kingdom is based on _______
1. Morphological characteristics
2. Embryotic structure
3. Ultra structure
4. Filamentous structure
Answer
Correct Anaswer : 1
Explanation:
Artificial classification is based on morphological structures of the plant i.e. artificial classification focuses on external structure of the plants than their internal structure.

Question 3 : Which among the following is incorrect about artificial classification of Plantae kingdom?
1. This classification is mainly based on external features of a plant than that of their internal features
2. It laid the concept of classification in plants
3. Sexual organs are given more preference than vegetative organs
4. Artificial classification classifies closely related species
Answer
Correct Anaswer : 3
Explanation:
Artificial classification is the oldest mode of classification in plantae kingdom. This classification laid the foundation for classification in plants. Artificial classification classifies closely related species under one category. However, in this mode of classification vegetative and sexual characteristics are given equal preference.

Question 4 : The mode of classifying plants as shrubs, herbs and trees comes under ________
1. Artificial classification
2. Natural classification
3. Phylogenetic classification
4. Whittaker’s classification
Answer
Correct Anaswer : 1
Explanation:
The mode of classifying plants as shrubs, herbs and trees come under artificial classification. In this mode of classification, morphological characteristics of plants are considered to be the basis of classification.

Question 5 : Which among the following are incorrect about natural classification?
1. In natural classification, only internal structures of the plants are considered
2. Natural classification overcomes the limitations of the artificial classification
3. Natural classification considers reproductive mode, embryotic structure and ultra structure of plants
4. Natural classification establishes close relationship between plants
Answer
Correct Anaswer : 1
Explanation:
Natural classification overcomes the limitations of the plants. Both internal and external structures are considered to be the basis of natural classification. Natural classification considers reproductive mode, embryotic structure and ultra structure of plants. It establishes close relationship between plants.
