Plant cells are eukaryotic while bacteria cells are prokaryotic. One characteristic difference between eukaryotes and prokaryotes is that eukaryotes have membrane-bound organelles, such as a nuclei, Golgi apparati, endoplasmic reticula, mitochondria, and so forth. Thus, choice c would be correct here (endoplasmic reticula can be rough or smooth depending on their specific functions).
Answer:
Explanation:
Water absorption and transport into a plant is mostly driven by transpiration of water from leaves. The process of water evaporation via specialised holes in the leaves called stomates is known as transpiration. As a result of the evaporation, a negative water vapour pressure develops in the leaf's surrounding cells.
Root pressure
−−−−−−−−−−−−
The cells around the xylem vessels in the root uses active transport to absorb mineral salts up a concentration gradient into the plant. This lowers the water potential in the xylem vessels. Water therefore passes from the living cells into the xylem vessels by osmosis and flows upwards
Capillary action
−−−−−−−−−−−−−−
Water tends to move up inside very narrow tubes due to the interactions between water molecules and the surfaces of the the tube. If the tube is sufficiently small, then the combination of surface tension (which is caused by cohesion within the liquid) and adhesive forces between the liquid and container wall act to propel the liquid.
Cohesion theory
−−−−−−−−−−−−−−
When water leaves the plant by transpiration, it creates a negative pressure ( suction ) on the water to replace the lost amount of water. It is like your typical straw when you suck on it. This negative pressure on the water pulls the entire column of water in the xylem vessel. This negative pressure due to transpiration is known as "transpiration pull". It is the main force in drawing water and mineral salts up through the plant.
Answer:
D. Pollution of the atmosphere
Explanation:
All the other answers would seem to only affect the designated local area. However, option D would affect both the local and global economy.
