Astudent is examining leaf cells. which organelle is most likely to be missing from the cells? a cell wall chloroplasts lysosomes a cell membrane

Lysosome is the organelle which will be missing in leaf cells.

Cell wall maintains the structural integrity of leaf cell. Cell membrane functions as a semi- permanent membrane which allows the transport of materials in and out of the cell required for cell metabolism. Chloroplast is the organelle which contains pigment chlorophyll, captures sunlight and conduct photosynthesis. Lysosome are membrane bound organelles, they are present in plant cells but not in leaf cells. Their function is digestion of cellular components and remove out waste from the plant and animal body. As, leaf is the photosynthesis region main function is synthesis of food not the absorption. The food prepared by leaves are send to other parts of plants. Therefore, leaf does not require lysosome.

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).
