Introduces botanical principles and processes. Includes basic anatomy and morphology on a range of scales: cellular structure and processes, tissues, organs and their functions. Students are required to attend weekly laboratory/tutorial sessions, but will not write laboratory exams or assignments. This course is not equivalent to BIOL 2125 for credit towards the BSc program, but serves as an acceptable prerequisite for BIOL 3275, BIOL 3353, or BIOL 3541 in place of BIOL 2125. Note: Credit cannot be counted for both BIOL 2135 and BIOL 2125.
