Answer:
The correct answer is - Roots allow plants to obtain water and nutrients, while shoots allow plants to obtain gases and sunlight.
Explanation:
Plants have two major parts of the body normally root and shoot. roots are the parts of plants that usually present under the ground and absorbed the essential nutrients and minerals for the life of the plant. Water is also absorbed by the roots that are used in the various processes such as transpiration and photosynthesis.
The shoot includes stem and leaves and responsible for the exchange of gases, particularly taking in carbon dioxide and removes oxygen with help of stomata. These also absorbs sunlight with help of chlorophyll present on the leaves.
The invention of the electron microscope opened up many doors for biologists as it helped them to view and learn the appearance of cells and their sub-cellular structures
<h3>What is an electron microscope?</h3>
Electron microscope are microscopes which helps biologists to view the appearances of cells of organisms which cannot be seen with our nak -ed eyes.
Generally, electron microscopes:
- Uses a beam of accelerated electrons as its source of illumination
- Helps in obtaining high resolution images of biological and non-biological specimens.
- It is also used in biomedical research
In conclusion, electron microscope helps biologists to view, learn and to also understand the appearance of cells and their sub-cellular structures

Covalent bond is when two atoms share one or more pairs of electrons, an example of this could be H20 or C02.
ionic bonds are when one or more electrons from am atom are removed and attached to another, which can result in positive or negative ions which attract each other, an example of this could be table salt.
