Honors Biology Semester 1 Final Study Guide with Complete Solutions How do plasmodesmata function in plant cell communication? Plasmodesmata are channels that connect plant cells, allowing the transfer of water, nutrients, and signaling molecules between them. What is the significance of operons in prokaryotic gene regulation? Operons allow prokaryotes to regulate the expression of genes by controlling the transcription of multiple genes simultaneously. How does the secondary str...

spontaneous generation : ancient belief: life can arise from nonliving matter Key scientists of spontaneous generation : Francesco Redi, John Needham, Lazzaro Spallanzani Francesco Redi : This scientist disproved spontaneous generation by showing that maggots do not spontaneously arise from decaying meat. John Needham : Believed there was a life force that caused spontaneous generation Lazzaro Spallanzani : replicated redi and needham's experiments, disproved of spontaneous generatio...
