The document discusses the six main parts of plants: flowers, leaves, stems, roots, seeds, and fruits. Leaves contain chlorophyll which helps plants produce food through photosynthesis. Their veins transport nutrients and water throughout the plant. Roots take in water and nutrients from the soil to support the plant. Seeds develop after pollination and contain an embryo that can grow into a new plant. Fruits form from the ripened ovary of a flowering plant and contain the plant's seeds.
