A scientist determined that a single celled organism has a membrane bound nucleus and organelles. The organism has a cell membrane and a cell wall composed of cellulose. In which kingdom does this organism belong. Group of answer choices

Plantae. The organism has a cell membrane, a cell wall, and membrane bound nucleus/organelles, meaning that there is no doubt that it is a eukaryote. That takes out kingdoms belonging to the domains bacteria and archaea, as they do not have any membrane-bound organelles (yes, that includes ribosomes). There are many clues, but the giveaway is at cellulose. Plants primarily have cellulose in their cell walls, to be more specific. However, the kingdom would be Plantae.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
