What's the difference between aquatic plants' leaves on the water and those under water? What's the effect?

It is a matter of course that submerged plants grow submerged leaves, but submerged leaves, floating leaves and floating plants can actually grow submerged leaves, but their shapes are different from those on the water.

This is because the submerged leaves are completely immersed in the water, completely isolated from the air, and the sunlight is also insufficient, so they absorb more gas and sunlight through thin lines or feather-like leaves, which can also reduce the impact of water flow.

Therefore, there is a way to distinguish between water leaves and water leaves: water leaves are generally wide and round, and underwater leaves are generally thin and long.

When purchasing aquatic plants, we should give priority to aquatic plants as far as possible, because the transformation from aquatic plants to aquatic plants takes some time. In the process of transformation, in order to adapt to the new environment, aquatic plants often have symptoms such as growth stagnation or local gangrene of leaves, and at the same time, the demand for nutrients is reduced, so the absorption rate of fertilizers will become very slow, and it will gradually return to normal growth until new aquatic plants grow one after another.

Before planting aquatic plants, it will be helpful to identify and select the aquatic plants to be planted. However, because there are some kinds of aquatic plants (mainly amphibians), their aquatic plants are easy to reproduce, cheap and have little damage during transportation, so many of them are aquatic plants sold in aquariums, and it is not easy to buy real aquatic plants.
