What are the major organs of a plant?

The major organs of a plant are fundamentally classified into four main categories: roots, stems, leaves, and flowers. Each of these organs serves a distinct and crucial function in the overall life cycle and health of the plant.

Roots anchor the plant in the soil, absorb water and essential nutrients, and play a role in storage. Stems serve both structural and transport functions, supporting the plant above ground while connecting roots and leaves. Leaves are primarily involved in photosynthesis, where they convert sunlight into energy for the plant, and also play a role in gas exchange and transpiration. Flowers are critical for reproduction, facilitating the processes of pollination and fertilization, which lead to the production of seeds and fruit.

Other options contain components that are either not primary organs or that mix functions and structures in ways that might lead to confusion. For example, "veins" and "petals" are parts found within leaves and flowers, respectively, so they don't qualify as major organs. "Seeds" are a product of reproduction and not an organ themselves, while "bark" is a protective layer of the stem but does not represent a distinct organ like the stem, roots, leaves, or flowers do. Thus, option A accurately identifies the key organs involved
