Flowering Plants And Their Parts (1966)

Explores the structure and function of green plants, focusing on their three main parts: roots, stems, and leaves. Roots anchor the plant and absorb water and minerals through root hairs. Stems transport this water upward through internal tubes and support the plant’s structure. Leaves, arranged to capture maximum sunlight, contain chlorophyll which enables photosynthesis—a process that converts sunlight, water, and carbon dioxide into food (starch) and releases oxygen. The film also highlights the role of flowers as specialized leaves that produce seeds, and discusses plant adaptations to different environments. For example, water hyacinths float and keep their leaves above changing water levels, while desert cacti store water and minimize evaporation through narrow spines instead of leaves. Together, these features help plants survive in diverse habitats while fulfilling their roles in the ecosystem.
