/15 Biology Chapter 9 : Topic 4 Artificial Vegetative Propagation 1 / 15 Artificial vegetative propagation is: A) Natural seed formation B) Human-assisted reproduction of plants C) Spore formation in fungi D) Sexual reproduction in plants Reasoning: Artificial propagation involves human techniques to produce new plants. 2 / 15 Stem cutting is a method in which: A) Seeds are planted in soil B) Leaves produce spores C) A piece of stem is cut and grown into a new plant D) Roots produce flowers Reasoning: A stem piece develops roots and grows into a complete plant. 3 / 15 Which plant is commonly propagated by stem cuttings? A) Rice B) Wheat C) Mango D) Rose Reasoning: Rose plants are easily grown using stem cuttings. 4 / 15 In stem cutting, new roots develop from: A) Seeds B) Cut surface of stem C) Flowers D) Leaves only Reasoning: Root formation occurs at the cut portion of stem. 5 / 15 Grafting is a method in which: A) Spores are planted B) A stem piece is buried in soil C) Two seeds are joined D) Two plant parts are joined to grow as one plant Reasoning: Grafting combines two plants into one functional plant. 6 / 15 In grafting, the upper part of the plant is called: A) Scion B) Bud C) Sucker D) Rootstock Reasoning: Scion is the shoot part that is grafted. 7 / 15 The lower part of a grafted plant is called: A) Bud B) Rootstock C) Scion D) Cutting Reasoning: Rootstock provides the root system. 8 / 15 The main purpose of grafting is to: A) Combine desirable traits of two plants B) Reduce plant growth C) Increase seed production D) Stop photosynthesis Reasoning: It combines qualities like disease resistance and good fruit quality. 9 / 15 Stem cutting is considered artificial because: A) It occurs naturally B) It needs fertilization C) It requires human intervention D) It involves seeds Reasoning: Humans prepare and plant stem pieces. 10 / 15 Which plant is commonly grafted? A) Grass B) Mango C) Wheat D) Banana Reasoning: Mango is commonly propagated by grafting. 11 / 15 A key advantage of stem cutting is: A) Produces seeds quickly B) Produces genetic variation C) Simple and inexpensive method D) Requires fertilization Reasoning: It is an easy and low-cost propagation method. 12 / 15 In grafting, successful union occurs when: A) Roots are removed completely B) Flowers are removed C) Leaves are detached D) Cambium layers of scion and rootstock join Reasoning: Cambium contact allows tissue fusion and growth. 13 / 15 Which part is responsible for nutrient uptake in grafting? A) Rootstock B) Scion C) Leaf D) Bud Reasoning: Rootstock provides roots for absorption. 14 / 15 Stem cutting and grafting are both examples of: A) Spore formation B) Artificial vegetative propagation C) Sexual reproduction D) Budding in animals Reasoning: Both are human-assisted plant reproduction methods. 15 / 15 Which statement best describes grafting? A) Seeds are used to grow plants B) A stem is buried to form roots C) Two plant parts are joined to grow as one plant D) Spores are released for reproduction Reasoning: Grafting combines scion and rootstock into one plant.
