Pinecones close in water to protect seeds and open in warm conditions for seed dispersal.
Pinecones close up when placed in water to prevent water loss, but open up in warm and dry conditions to disperse seeds. This mechanism helps protect their seeds from unfavorable conditions by allowing them to open up and release seeds when conditions are suitable for germination. It ensures that seeds have a better chance of germinating in an environment with ample sunlight, increasing the plant's chances of successful reproduction.
