Heliotropism, a form of tropism, is the diurnal or seasonal motion of plant parts (flowers or leaves) in response to the direction of the Sun. The habit of some plants to move in the direction of the Sun, a form of tropism, was already known by the Ancient Greeks. They named one of those plants after that property Heliotropium, meaning "sun turn".
In the process of plant roots growing in the direction of gravity by gravitropism, high concentrations of auxin move towards the cells on the bottom side of the root. This suppresses growth on this side, while allowing cell elongation on the top of the root. As a consequence of this, curved growth occurs and the root is directed downwards. [3]
The plants in this region have yet to reach reproductive maturity, thus they do not contribute to the seed dispersal potential of the population. The final region is the seed shadow region. In this region, inflow of seeds from the reproductive core is occurring, but because of environmental conditions germination or seedling survival is ...
The Venus flytrap is one of a very small group of plants that are capable of rapid movement. Rapid plant movement encompasses movement in plant structures occurring over a very short period, usually under one second. For example, the Venus flytrap closes its trap in about 100 milliseconds. [1]
Plant perception is the ability of plants to sense and respond to the environment by adjusting their morphology and physiology. [1] Botanical research has revealed that plants are capable of reacting to a broad range of stimuli, including chemicals, gravity, light, moisture, infections, temperature, oxygen and carbon dioxide concentrations, parasite infestation, disease, physical disruption ...
Plants act in similar ways as they can also use water currents, winds, or moving animals to transport their gametes. Seeds, spores, and fruits can have certain adaptations that aid in facilitation of movement. [11] Active Dispersal (Density-Dependent Dispersal) In active dispersal, an organism will move locations by its own inherit capabilities.

Epilobium hirsutum seed head dispersing seeds. In spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. [1] Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living vectors such as birds.
