All living things need water to stay alive, and plants are living things! Plants, however, need much more water than many living things because plants use more water than animals.

A few weeks ago I went on a trip to Wisely, at the Royal Horticultural Garden and it was really exciting because there were some flowers and trees that I didn’t know before and now I know.

The trip to Wisely also made me want to know more about plant history, and plant information and how plants use water.





Reasons why plants need water:

  • Photo synthesis
  • Nutrient transfer
  • Germination
  • Transpiration

Photo synthesis:

Photo synthesis is what plants do to create their food, and water is critical to the process. Water enters a plant’s stem and travels up to its leaves, which is where photo synthesis actually takes place.

Nutrient transfer:

A nutrient cycle is the movement and exchange of organic and inorganic matter back into the production of living matter. The process is regulating by the food web pathways that decompose matter into mineral nutrients. Nutrient cycles occur within all eco systems.


Germination is the process by which a plant grows from a seed. The most common example of germination is sprouting of a seedling from a seed of an angiosperm or gymnosperm.


Transpiration: Transpiration is the process of water movement through a plant and it’s evaporation from aerial parts, such as leaves stem and flowers…. leaf surfaces are dotted with pores called stomata , and in most plants they are more numerous on the underside of the foliage .

The reason I choose this picture was because it is an extraordinary flower.  It is called a hellebore and it smelt really good.



This is a Juania australis. It is a very interesting flower because it has a palm tree at the top and little flowers at the bottom. I think that it is beautiful.
