Leaves are organized in a way that helps them conduct photosynthesis. Explain how the structure of the leaf helps it perform photosynthesis. Write a brief explanation here.

For the photossynthesis there are requirement of cholorplast which is found on the surface of the plant leaves mostly that traps the light and convert light energy to the storage energy or glucose. Leave have larger surface area so the maximum amount of light can be traped for the photosyntheis by the cholorplast present in palisade cells.

Other than this leaves also helps in the gaseous exchange with stomata; small openings, by allowing carbon dioxide and oxygen into the leafe and outof the leave respectively. The veins helps in the transport of the gluscose and nutrition.

just finished the test, the answer is d, greg is the least cost-effective because he charges the most for the project

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
