Plants and Wind

Plants and Wind

For plants it is not only freshwater availability, soils richness, sun and air but also physical forces such as wind that play a role in the existence and survival of plants. For instance a plant that faces strong winds might have its branches break or it might be blown away altogether.

Wind can also blow away humidity and thus rapidly making the water evaporate thus depriving the plant from enough water in case of arid lands. It is thus essential to grow wind breaks in the form of strong high trees that protect the rest of the crops grown in a farm from strong winds.

It is interesting to note that as plants adapt and acclimatize to conditions such as availability or shortage of water, soil nutrients and soil physical properties and the amount of light available they also adapt to other physical conditions such as the speed, strength and direction of wind. Too much wind can harm the plant, yet some wind can keep the branches dancing and happy helping it grow some resistance.

Seaweeds

It is interesting to note the seaweed anchored to the rocks on the shores of Alexandria. It would be interesting to study them more and study their ecosystem.

Do

Take photos of seaweeds on rocks on the shores of Alexandria.
