Modified Stems Of Plants — a labelled NEET Biology diagram with a definitions lexicon.
Modified Stems of Plants Labelled parts: Stem modifications, Underground stems, Rhizome, Tuber, Bulb, Corm, Thorn, Phylloclade, Runner, Stolon, Node, Scale leaf, Bud, Eye (bud), Fleshy scale leaves, Apical bud, Reduced stem disc, Adventitious roots, Leaf, Stem thorn, Flattened stem, Areole, Spine, Internode, New plantlet, Mother plant, Daughter plant. An underground, horizontal, modified stem that grows parallel to the soil surface and produces roots and shoots from its nodes. FYI: Ginger and turmeric are classic examples of plants that reproduce and store food reserves using rhizomes. A swollen, fleshy, underground storage modification of a stem (e.g., potato). The storage tissue is derived from the stem cortex. FYI: Potatoes store starch in their tubers, allowing the plant to survive unfavorable conditions and regenerate shoots. A modified underground storage structure composed of fleshy, scale-like leaves (modified leaves) arranged around a central stem (underground stem). FYI: Onions and garlic are examples of plants that store food reserves in their bulbs, which are primarily composed of modified leaves. A solid, fleshy, underground storage modification of a stem (e.g., taro). Unlike tubers, the corm is not derived from the stem cortex. FYI: Corms store food reserves and are used for vegetative propagation; examples include colocasia and taro. A modified stem that assumes the green, leaf-like appearance and function, but is structurally a stem (e.g., Opuntia cactus). FYI: Phylloclades are a key adaptation in xerophytic plants, allowing them to maximize photosynthesis while minimizing water loss through leaves. A specialized, horizontal, creeping stem that grows above the ground surface and produces new plantlets at its nodes (e.g., strawberry). FYI: Runners are a type of vegetative propagation that allows plants to quickly colonize new areas by forming new, genetically identical plants. A horizontal, creeping stem that grows along the soil surface, often connecting the parent plant to a new plantlet (e.g., mint). FYI: Stolon formation is a common method of asexual reproduction in plants, ensuring the rapid spread of the species. Roots that arise from parts of the plant other than the primary root tip, such as from the stem or leaves. FYI: When a plant is propagated by cuttings, the roots that grow from the cut stem are examples of adventitious roots. A specialized, scale-like structure found on the stems of certain plants, particularly cacti, which often bears flowers or spines. FYI: Areoles are characteristic features of cacti and are the points from which spines and flowers emerge, making them important taxonomic markers. The segment of a plant stem located between two successive nodes (where leaves or branches attach). FYI: The length of the internode can vary greatly and is often involved in the plant's growth habit and overall morphology.
