Are smooth muscle cells surrounded by a basal lamina?

Look at the picture below . what does this picture represent ?

Which level of taxonomy has the fewest organisms?

Molecules like glucose and amino acids are not lipid soluble, so cannot cross the cell membrane by simple diffusion. instead, they are shuttled across by carrier proteins in the membrane from high to low concentration. does this process require energy from the cell? this is an example of what type of molecular movement?
