Parthenocissus tricuspidata leaves a smooth child down with the direction of Parthenocissus tricuspidata climbing the wall.Because it is a foot to climb up, grow a foot to go up firmly stick to the wall, waiting for the growth of new leaves.Then grow another foot and continue to climb.Its feet are on the opposite side of the petiole, and when it climbs up, it will pull the whole stem up, and the leaves will naturally face down.
Every time the ivy takes a step toward the wall, it drives the stems and leaves to climb on the vertical outer wall.Over time, the tip of the leaf will point downward due to the gravity of the earth.
It can be found that the leaves of Parthenocissus tricuspidata not only face down smoothly, but also are distributed very evenly, and there is almost no overlap between each leaf.This is actually a phenomenon called leaf mosaic.They try to fill in the gaps as much as possible to get more sunlight, and the leaves are spread out to ensure that all the leaves can get more uniform light.The mosaic effect of leaves can make it get sunshine in a larger area, protect roots, reduce water loss, maintain the humidity of attached walls, and form a good living environment suitable for its growth.
Parthenocissus tricuspidata climbs up by one foot, not by one foot.There are tendrils on its branches, and the top of the tendrils has sticky suckers, which are its feet, and when they encounter objects, they will stick to them.Every time it grows a foot, it climbs up and clings to the wall tightly.Wait for new branches and new feet to grow out, and then the new feet will continue to climb up the relay in general.And it also branches, so there may be many feet climbing up at the same time.
