  • Question 1
    1 / -0
    The vegetative reproduction in Bryophyllum takes place through which part of the plant?
    Solution
    Vegetative reproduction is a type of asexual reproduction in which new plants are formed from the vegetative parts like leaf, root, stem, etc. Vegetative reproduction in Bryophyllum takes place through leaves.
    The leaf buds are produced on the edge of the Bryophyllum leaf. The buds fall from the leaf on the soil. These buds can develop into individual plants when favourable conditions are provided. 
    Thus, the correct answer is option C. 
  • Question 2
    1 / -0
    Placing seeds on or in the ground for future growth is called_______
    Solution
    When you plant seeds in the ground, you sow them. Therefore, Option C is correct.
  • Question 3
    1 / -0
    Which of the following fruits are fleshy and juicy?
    Solution
    The fruit is the ripened ovary. The seeds develop from the ovules. The seed contains an embryo enclosed in a protective seed coat. Some fruits are fleshy and juicy such as mango, apple and orange. Option D is correct.

  • Question 4
    1 / -0
    Vegetative propagation refers to the formation of new plants from
    Solution
    Vegetative propagation occurs through vegetative parts like root, stem, leaves. Flowers are meant for sexual reproduction in plants.
    Option "B" is correct.
  • Question 5
    1 / -0
    In potatoes, new plants grow from
    Solution
    In potatoes, new plants grow from eyes or small scars present on the surface. Likewise other plants such as ginger and turmeric can also grow from eyes. 
    Option "D" is correct.
  • Question 6
    1 / -0
    The plant/s in which vegetative propagation is found naturally is/are:
    Solution
    • In Bryophyllum vegetative propagation occurs through buds formed in the leaf margins. 
    • However, Sugarcane and Rose are propagated through stem cuttings (artificial method of vegetative propagation).
    • So, the correct answer is 'Bryophyllum'
  • Question 7
    1 / -0
    The development of an offspring from any part of the body is called:
    Solution
    • Vegetative reproduction is a type of asexual reproduction mainly observed in plants. 
    • Since the vegetative part of the plant propagates to produce offspring hence it is also called vegetative propagation. 
    • The new plant is genetically identical to the parent plant.
    Thus, the correct answer is option C.
  • Question 8
    1 / -0
    Flowers which have both stamens and pistils are called:
    Solution
    • A flower that lacks one or two of the 4 parts is called an incomplete flower.
    • A bisexual flower has both stamen and pistil in the same flower.
    • A unisexual flower has one of the reproductive organs, i.e. either stamen or pistil.
    So the correct option is option B.
  • Question 9
    1 / -0
    What are spores?
    Solution
    • The spores are asexual reproductive bodies. 
    • Each tiny spore is covered by a hard protective coat to withstand unfavourable conditions such as high temperature and low humidity. So they can survive for a long time. 
    • Under favourable conditions, a spore germinates and develops into a new individual. Plants such as mosses and ferns also reproduce by means of spores.

    Thus, Option "A" is correct.
  • Question 10
    1 / -0
    Name the reproductive organ of plants.
