Transpiration

Water is turned from liquid to gas by heat from the sunlight

Evaporation occures thriugh the stomatal pores

The water is found in the soil where the roots take it up to the leaf through the xylem

The water diffuses and turns into a diffusion gradient

Plants and Stimuli, Geotrapism and Phototrpism

Stimuli is the change in the environment. For example Change in temperature, light and gravity
The Receptor detects the Stimuli
The Receptor then sends the Stimuli to the Response
The plant responds differently to each stimuli for example if the stimuli is light then the it will respond as a phototropism if the stimuli is Gravity then it will respond as a Geotropism

Geotropism
Geotropism is the growth response to gravity

Phototropism
Phototropism is the growth responce to light. If the light is shining directly above the stem tip, the stem will grow upwards. But if the sunlight is shining from the side then the stem tim will bend towards the light.

Uptake of water notes

• The branching pattern of the roots increases the surface area of itself for absorbstion of water
• Roots will branch out to find a water source
• Epidermal cells have root hair with also increase the area of absorbsion of water
• There is movement of active transport of minerals and osmosis of water in the epidermal cells
• The minerals are dissolved in water and is tranported up to the leaf by the xylem
