7 0

Answer:

The cholodny-went model was proposed in 1927. This model explains the capability of the shoots to grow in the direction of the sunlight whereas the capability of the roots to grow downwards. The hypothesis suggested that both these directional growth occurred due to the asymmetrical distribution of the plant hormone, auxin.

How do the resurection of fern, crysts of brine shrimps and tardigrade survive with no water?
ehidna [41]
They survive without water by entering a special mode, otherwise called as shriveling. They can lose even 95% of water in their body and still live, even though they would look like dead plants, they would actually be alive. In the absence of water, tardigrades use a sugar called trehalose, which becomes their source of life until they find some water.
