1) Describe the process of transpiration in vascular plants.
This is the process of which plants lose excess water into the atmosphere through the stomata located on the underside on the plant. leaves. Most of the water absorbed by the plant's root is lost through transpiration. During photosynthesis, stomatas open to allow the intake of carbon dioxide and the release of oxygen. In this process, large amounts of water are lost to the enviornment via transpiration.
2) Describe any experimental controls used in the Investigation.
The control of the experiment is the transpiration of the plants under regular conditions and time intervals (same heat, without fan/heater/lamp).
3) What environmental factors that you tested increased the rate of transpiration? Was the rate of transpiration increased for all plants tested?
The factors that I tested that increased the rate of transpiration were heat, light, and wind. Wind and heat increased the rate of transpiration for all the plants, but the light only increased the rate of transpiration for the arrowhead, coleus, devil's ivy, english ivy, and geranium plants.

4) Did any of the environmental factors (heat, light, or wind) increase the transpiration rate more than the others? Why?
Overall, wind yielded the highest transpiration rate out of all the factors. Different plants transpire at different rates in order to be well-adapted to the different environments they live in.
5) Which species of plants that you tested had the highest transpiration rates? Why do you think different species of plants transpire at different rates?
The rubber plant had the highest rate of transpiration. Different plants transpire at different rates in order to be well-adapted to the different environments they live in.
6) Suppose you coated the leaves of a plant with petroleum jelly. How would the plant's rate of transpiration be affected?
7) Of what value to a plant is the ability to lose water through transpiration?
The rubber plant had the highest rate of transpiration. Different plants transpire at different rates in order to be well-adapted to the different environments they live in.
6) Suppose you coated the leaves of a plant with petroleum jelly. How would the plant's rate of transpiration be affected?
Transpiration would be unable to take place because the petroleum jelly covers the stomatas of the leaves, not allowing neither oxygen and water vapor to leave the plants and prevents carbon dioxide from entering the plant.
7) Of what value to a plant is the ability to lose water through transpiration?
Transpiration allows the plant to regulate homeostasis, humidity in the atmosphere, and moisture in the soil. Water that becomes part of the transpiration process is used as a vehicle to deliver nutrients from the soil into the plant.
