The correct option is (c) 1 and 3 only
Explanation
In angiosperms (flowering plants), plant parts are broadly categorized into two groups based on their primary functions: vegetative parts, which are involved in growth, nutrition, and metabolism, and reproductive parts, which are involved in sexual reproduction.
Statement-wise Analysis:
- Statement 1 is Correct: Roots, stems, and leaves are classified as the vegetative parts of a plant. Their primary roles include the absorption of water and minerals, structural support, transport of nutrients, and photosynthesis. They do not directly participate in sexual reproduction.
- Statement 2 is Incorrect: Flowers are the reproductive units of a plant, not vegetative parts. The primary function of a flower is to facilitate sexual reproduction by producing gametes (pollen and ovules) and ensuring fertilization to produce seeds and fruits.
- Statement 3 is Correct: Vegetative propagation is a form of asexual reproduction where new plants are produced from the vegetative parts (roots, stems, or leaves) of the parent plant. This process does not involve the formation or germination of seeds.
Key Takeaway:
Vegetative parts (roots, stems, leaves) sustain the plant's life, whereas reproductive parts (flowers, fruits, seeds) ensure the continuation of the species through sexual reproduction. Vegetative propagation utilizes vegetative parts to create clones without seeds.
