Tendrils in plants, such as those in pea plants, enable climbing by exhibiting thigmotropism, a directional growth response to physical contact. Specialized cells on the tendrils, called touch-sensitive cells or pulvini, respond to mechanical stimuli. When the tendril touches a support, these cells undergo rapid water movement, causing differential growth and curvature towards the support. This allows the plant to anchor and climb. The sensitivity to touch is attributed to a combination of hormonal changes and ion movements within the cells, triggering the growth response. Overall, this mechanism ensures efficient and adaptive climbing behavior in plants with tendrils.
Directional growth in plants, known as tropism, is crucial for their response to stimuli. Phototropism, for example, causes stems to grow towards light, optimizing photosynthesis. Gravitropism influences root growth downward, aiding in soil anchorage. Thigmotropism, a response to touch, directs moveRead more
Directional growth in plants, known as tropism, is crucial for their response to stimuli. Phototropism, for example, causes stems to grow towards light, optimizing photosynthesis. Gravitropism influences root growth downward, aiding in soil anchorage. Thigmotropism, a response to touch, directs movements like climbing in tendrils. These tropisms result from differential cell elongation influenced by hormonal changes. When stimuli trigger uneven growth, plants appear to move by adjusting their structure. While the entire plant remains stationary, the localized directional growth gives the illusion of movement, allowing plants to dynamically adapt to environmental cues and optimize their positioning for growth and survival.
Tendrils respond to touch through thigmotropism, a growth phenomenon. When a tendril makes physical contact with a support, specialized cells known as pulvini perceive the touch. Rapid ion fluxes and changes in hormone distribution occur within these cells, inducing a rapid osmotic response. Water mRead more
Tendrils respond to touch through thigmotropism, a growth phenomenon. When a tendril makes physical contact with a support, specialized cells known as pulvini perceive the touch. Rapid ion fluxes and changes in hormone distribution occur within these cells, inducing a rapid osmotic response. Water movement causes differential growth on the side facing the support, resulting in curvature and coiling around the object. This process allows the tendril to anchor securely and support the plant as it climbs. The touch-sensitive mechanism of pulvini ensures an adaptive and efficient response, enhancing the plant’s ability to find and utilize external structures for upward growth.
Tendrils exhibit a unique growth pattern compared to general plant growth. Tendrils display thigmotropism, a specialized response to touch, causing them to coil around a support structure.

Tendrils exhibit a unique growth pattern compared to general plant growth. Tendrils display thigmotropism, a specialized response to touch, causing them to coil around a support structure. Unlike typical plant growth, where cells elongate uniformly, tendrils undergo localized, differential growth in response to mechanical stimuli. This specific response enables tendrils to efficiently anchor and climb, optimizing resource utilization. The significance lies in the adaptive advantage for plants seeking support and sunlight. The ability to navigate and grasp structures enhances their chances of survival, demonstrating the evolutionary advantage of specialized growth patterns tailored to specific environmental challenges.
In octahedral coordination entities [Ma₃b₃], two types of geometrical isomerism exist: cis and trans isomers. In cis isomers, similar ligands are adjacent, while in trans isomers, similar ligands are opposite each other. In [Co(NH₃)₃(NO₂)₃], there are two possible isomers. The cis isomer has three aRead more
In octahedral coordination entities [Ma₃b₃], two types of geometrical isomerism exist: cis and trans isomers. In cis isomers, similar ligands are adjacent, while in trans isomers, similar ligands are opposite each other. In [Co(NH₃)₃(NO₂)₃], there are two possible isomers. The cis isomer has three ammonia (NH₃) ligands adjacent to three nitrito (NO₂) ligands. The trans isomer has the ammonia and nitrito ligands positioned opposite each other. These isomers exhibit distinct spatial arrangements around the central cobalt atom, resulting in different chemical and physical properties. Geometrical isomerism is significant in understanding the diversity of coordination compounds.
