Which structure is found in some but not all plant cells? vacuole ribosome cell wall lysosome

Lysosome

Explanation:

Lysosomes (from Greek lysis, breakage, destruction) are membrane pockets that contain enzymes capable of digesting organic substances. In general, plant cells do not have lysosomes, but some rare plant species have lysosomes, as do seeds. The role of lysosomes (intracellular digestion) in plants and yeast is played by the cell juice vacuole (tonoplast).

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
