Node: A point of attachment of a leaf or a twig on the stem in seed plants. A node is a very small growth zone. Pedicel: Stems that serve as the stalk of an individual flower in an inflorescence or infrutescence. Peduncle: A stem that supports an inflorescence or a solitary flower. Prickle: A sharpened extension of the stem's outer layers, e.g ...
The functions of a plant's growing tips – its apical (or primary) meristems – include: lengthening through cell division and elongation; organising the development of leaves along the stem; creating platforms for the eventual development of branches along the stem; [4] laying the groundwork for organ formation by providing a stock of ...
In biology, phototropism is the growth of an organism in response to a light stimulus. Phototropism is most often observed in plants , but can also occur in other organisms such as fungi . The cells on the plant that are farthest from the light contain a hormone called auxin that reacts when phototropism occurs.
It resembles the different growth processes for a leaf, a stem, etc. On top of the gradual growth of the plant, the image reveals the true meaning of phototropism and cell elongation, meaning the light energy from the sun is causing the growing plant to bend towards the light aka elongate. Plant growth and development are mediated by specific ...
[1] [2] The new growth from seed germination that grows upward is a shoot where leaves will develop. In the spring, perennial plant shoots are the new growth that grows from the ground in herbaceous plants or the new stem or flower growth that grows on woody plants. In everyday speech, shoots are often synonymous with stems.
Biomass partitioning is the process by which plants divide their energy among their leaves, stems, roots, and reproductive parts.These four main components of the plant have important morphological roles: leaves take in CO 2 and energy from the sun to create carbon compounds, stems grow above competitors to reach sunlight, roots absorb water and mineral nutrients from the soil while anchoring ...
Secondary growth thickens the stem and roots, typically making them woody.Obstructions such as this metal post and stubs of limbs can be engulfed. In botany, secondary growth is the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken, while primary growth is growth that occurs as a result of cell division at the tips of stems ...
A geophyte (earth+plant) is a plant with an underground storage organ including true bulbs, corms, tubers, tuberous roots, enlarged hypocotyls, and rhizomes. Most plants with underground stems are geophytes but not all plants that are geophytes have underground stems. Geophytes are often physiologically active even when they lack leaves.
