Question

If a plant absorbs 1 litre of water how much water will be used to produce carbohydrate

Answer 1

Water is the most limiting abiotic (non-living) factor to plant growth and productivity, and a principal determinant of vegetation distributions worldwide. Since antiquity, humans have recognized plants' thirst for water as evidenced by the existence of irrigation systems at the beginning of recorded history. Water's importance to plants stems from its central role in growth and photosynthesis, and the distribution of organic and inorganic molecules. Despite this dependence, plants retain less than 5% of the water absorbed by roots for cell expansion and plant growth. The remainder passes through plants directly into the atmosphere, a process referred to as transpiration. The amount of water lost via transpiration can be incredibly high; a single irrigated corn plant growing in Kansas can use 200 L of water during a typical summer, while some large rainforest trees can use nearly 1200 L of water in a single day!

Answer 2

If a plant absorbs 1 litre of water how much water will be used to produce carbohydrate is 1 millilitre.

Explanation:

• When stomata open, water is lost to the atmosphere at a rapid pace in comparison to the minimal amount of CO2 absorbed.
• An average of 400 water molecules are lost for each CO2 molecule obtained across plant species.
• The balance between transpiration and photosynthesis is critical to plant survival.
• Stomata must remain open to generate sugars but risk dehydration in the process.
