Let's see which option fits with each characteristic.
Multicellular, or having more than one cell, could be any of these Kingdoms. These are all eukaryotic kingdoms, and eukaryotes cannot be unicellular.
Heterotrophic, or something that cannot produce its own food, can be all of these except Plantae, plants of this kingdom are autotrophic, as they mainly produce their own food (think photosynthesis).
Having a cell wall applies to all of these except Animalia. Animal cells don't need cell walls, as they don't require such a rigid structure as plants. Animals will typically have other supporting structures, such as bones or hydrostatic skeletons.
Being unable to move applies to all of these Kingdoms except Animalia and Protista (which move using their cilia or flagella). Plantae and Fungi don't have the means to move by themselves.
So, the only kingdom that has not been ruled out by one of the criteria is Kingdom Fungi !
The Nucleus controls and manages the activities of the cell
100% of algae uses photosynthesis to make their own food.
It will transported across plasma membrane by simple diffusion. simple diffusion refers to a process by which molecules will pass across plasma membrane without the aid of channels located on the surface of the membrane. since the molecule identified was polar once it enter in hydrophobic region of the membrane it will not stick since this region is non-polar and therefore it will move easily across that region.
