Match the following: 1. Stamen (a) Spore formation 2. Zygote (b) Modified shoot 3. Fungi (c) Tube-like structure 4. Onion (d) Male sex organs 5. Style (e) Single-celled structure

1 - (d) Stamen is the male reproductive organ of a flower. It is the third whorl. It consists of anther and filament. 2 - (e) The male and female gamete fuse to form a diploid cell called a zygote. This process is known as fertilisation. It is a single-celled structure that divides continuously to form an embryo. 3 - (a) Fungi like Rhizopus reproduce through spore formation. In this process, small dormant structures [spores] are produced in a sac-like structure called sporangium. These spores develop into a new organism when provided with suitable conditions. 4 - (b) An onion is a modified form of stem called the bulb. It has thick and succulent leaves. It reproduces through the bud. 5 -(c) Stigma is the female reproductive part of the flower. It is the innermost whorl. It consists of the stigma, style and an ovary. Style is a tube-like structure that connects the stigma and the ovary. Stigma is the topmost part of the pistil. The ovary is the swollen basal part of the pistil that consists of ovules. Thus, the final answer is : 1. Stamen (d) Male sex organs 2. Zygote (e) Single-celled structure 3. Fungi (a) Spore formation 4. Onion (b) Modified shoot 5. Style (c) Tube-like structure
