Penecillin doesn't attack the cell wall directly, but inhibits one of the enzymes involved in its synthesis in bacteria. The same enzyme isn't present in plants, so they are unaffected.

The plant cell wall is made up of cellulose, whereas the bacterial one is peptidoglycan (sugars and amino acids). Chemically, they're not very similar.

How does penicillin get energy?

penicillin comes from a fungus. the fungus grows and lives by breaking down organic molecules of decomposing animal and plant life. penicillin itself doesnt "get energy" but rather is derived from the fungus. if you are asking how penicillin destroys some microorganisms - the answer is that it interferes with the ability of a newly formed bacterium to develop a cell wall. a bacterium cannot survive without a cell wall.
