Answer:
Gaseous exchange
Explanation:
In terrestrial plants, gaseous exchange occurs mainly in leaves and to a lesser extent in the roots and stems. In leaves, the structures involved in gaseous exchange are stomata and spongy mesophyll tissues.
The stoma comprises of a stomatal pore and two specialized guard cells. The guard cells are structurally adapted by having chloroplasts, thicker, inelastic inner walls and thinner and elastic outer walls.
The stomata mostly opens during the day. They open when the guard cells are turgid.When the guard cells are flaccid, the thinner outer wall shrinks. The inner thicker walls curvature reduces causing the stomata to close.

The advantage gained by staining cells are the following:
- provides a better and clear image of the cell's structure
- staining will help in differentiating the different parts of the cell
- this will enhance its view under the microscope.
The correct answer is 10 m/s. This is because:
F = ma
45 = 5m
90 = 5m * 2
Therfore a = 10 m/s
Option (A) lining the straw is correct.
<h3>What is the anatomy of Earthworm?</h3>
- An earthworm is a terrestrial invertebrate and a member of the phylum Annelida.
- They have a tube-within-a-tube body structure, corresponding external and internal segmentation, and typically include setae on each segment.
- They can be found wherever the soil, water, and temperature permit.
- The body of an earthworm is composed of a digestive tube and a thick cylindrical muscular tube that forms the body.
- The body is divided into segments, and furrows on the surface of the body serve as markers for the segment boundaries.
- The top of the first segment, which encloses the mouth, is a lobe made of muscle and flesh.
