Plant Tissues - 1 Although the basic plant organization was presented during our introduction, at this time we are going to look in depth at the structure of the plant body, first at plant tissues and progressing to the shoot and root systems. Plant cells are specialized for certain functions, as are the cells of all multicellular organisms. The cells and tissues of roots, stems and leaves are the result of three developmental processes: growth, morphogenesis and differentiation. Growth consists of cell division and cell enlargement, two processes that result in change in size and form of the plant body. o Cell division in plants occurs in meristems o Cell enlargement follows division, and involves morphogenesis. Morphogenesis describes the particular shape and form a plant takes on during growth, determined by the plane of cell division and cell expansion during growth. Differentiation is the process by which cells specialize for function forming the tissues of the plant.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
