Which factors below helped the plants grow taller?
There are four primary factors that affect plant growth: light, water, temperature and nutrients. These four elements affect the plant’s growth hormones, making the plant grow more quickly or more slowly.
Does water affect the growth of a plant hypothesis?
We assessed the effects of varying amounts of water on plant growth and formed a hypothesis that laid the foundation down for our experiment: “If we fluctuate the amount of water given to each fast plant then the plant growth of each plant with physically vary; a greater amount of water will cause plants to grow taller …
What effect does the amount of water have on plant growth hypothesis?
If a plant’s soil has too much water, the roots can rot, and the plant can’t get enough oxygen from the soil. If there is not enough water for a plant, the nutrients it needs cannot travel through the plant. A plant cannot grow if it doesn’t have healthy roots, so the proper balance of water is key when growing plants.
What is the role of water in plants?
Water is used for transpiration carrier of nutrients from the soil to green plant tissues. Water forms over 90% of the plant body by green or fresh weight basis. Plants can synthesis food through photosynthesis only in the presence of water in their system. Water helps to maintain the turgidity of cell walls.
What is the control group in a plant experiment?
A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results.
