1)
Question: What is the mode of reproduction that requires only one parent?
Answer: Asexual
Explanation: Asexual reproduction is a type of reproduction where new plants are produced from a single parent without the formation of seeds .
2)
Question: What is the mode of reproduction that requires male and female gametes?
Answer: Sexual
Explanation: Sexual reproduction involves the fusion of male and female gametes to form a zygote which develops into a new plant .
3)
Question: What is the name of the process in which new plants are grown from vegetative parts?
Answer: Vegetative
Explanation: Vegetative propagation is a type of asexual reproduction where new plants are grown from roots, stems, or leaves .
4)
Question: What is the name of the reproduction method in yeast?
Answer: Budding
Explanation: In budding, a small outgrowth called a bud develops on the parent organism (like yeast) which later detaches and grows into a new organism .
5)
Question: What is the process in algae where new individuals are formed by breaking into pieces?
Answer: Fragmentation
Explanation: Fragmentation is a method of asexual reproduction where an organism like algae breaks into pieces and each piece grows into a new individual .
6)
Question: What reproductive structure is used by bread mould and ferns for reproduction?
Answer: Spores
Explanation: Spores are tiny, light reproductive bodies that are produced in sporangia and help in asexual reproduction .
7)
Question: Which reproductive part of a flower contains male gametes?
Answer: Anther
Explanation: The anther is part of the stamen (male reproductive part) and contains pollen grains which have male gametes .
8)
Question: What is the process of fusion of male and female gametes called?
Answer: Fertilisation
Explanation: Fertilisation is the process by which male and female gametes fuse to form a zygote, which develops into an embryo .
9)
Question: What is the reproductive organ of a plant?

10)
Question: What is the reproductive structure in Bryophyllum from which new plants arise?
Answer: Leaves
Explanation: In Bryophyllum, buds present on the margins of leaves grow into new plants, which is an example of vegetative propagation .
