In most plants, the leaves are the main food factories. They capture the sun's energy with the help of chlorophyll in the leaf cells. The chlorophyll traps and packages the energy from the light of the sun in a process called photosynthesis. Leaves usually have a large surface so they can collect the most sunlight.
The relationship between them is chlorophyll because that is the only pigment that interacts with the light proteins by transferring excited electrons to the primary electron acceptor.
Also, it is made up of water and contains enzymes, organelles, salts and various organic molecules. Furthermore, cytoplasm functions by supporting and suspending organelles and cellular molecules. However, example of cytoplasm includes: mitochondria, ribosomes while nucleus is an example of non-example of cytoplasm.
There's tropism and stimulus, for starters. Gravity, light, and touch can all be used as stimuli. So it is debatable... If the plant is reaching upwards towards a window that is above it... It would then be light, and the plant's response would be to reach upward.
Hope this helps and if it does, don't be afraid to give my answer a "Thanks" and maybe a Brainliest?
