Concept explainers
To determine:
The benefits of phytoremediation.
Introduction:
Phytoremediation employs green plants and their associated microorganisms to remove, inhibit or neutralize hazardous environmental contaminants. It is used to remove organic and inorganic wastes from the soil.
To determine:
The qualities of plants that are suitable for use in phytoremediation.
Introduction:
Phytoremediation is a cost-effective method to reduce the toxic effects of contaminants in the environment. The contaminants in the environment pose a problem for wildlife and human health.
To determine:
The problems associated with phytoremediation.
Introduction:
Phytoremediation is an alternative to engineering procedures. Phytoremediation technology includes phytostabilization, phytodegradation, phytovolatilization, and phytoextraction.

BIOLOGY:THE ESSENTIALS (LL) W/CONNECT
- Engineers have designed a smaller version of such a container that can be used to seal off a small part of the plant. One version of this device, called a leaf chamber, is shown below. When a scientist uses this device on a plant, they don’t need to break the leaves off the branch or stem they are attached to. The leaf chamber makes an airtight seal around the stem or branch even though it is sticking out of the chamber. Using this device, scientists detected the most change in O2 and CO2 levels inside the chamber when a leaf is in the chamber. They only detected a small change in O2 and CO2 levels in the chamber when a green stem was placed in the chamber. No change was detected when a root or a brown stem was placed in the chamber. Why do you think a scientist would prefer not to remove the leaves from a tree or a plant in order to take these sorts of measurements?arrow_forwardPhytoremediation is the utilization of plants in the clean up of a polluted area.
