Plant Physiology – Plant Evolution, Structure, and Growth Discussion Questions & Activities – Lectures: Jan. 23-28, 2008 Part 1: Discussion Questions: 1. How do plant and animal cells differ? How are they similar? How does the growth of a plant differ from that of an animal? When does a tree stop growing? What parts of a tree are active in growth? Plant cells have cell walls, chloroplasts, and a large central vacuole, which are not found in animal cells. Animal cells have centrioles and organelles used for locomotion, which are not found in plant cells. Plant and animal cells have a number of common organelles, including nuclei, cell membranes, and ER. Plants, unlike animals, have continuous growth. Apical meristems elongate shoots and roots through primary growth. Lateral meristems add girth to woody plants through secondary growth. a. While adult animals generally have very few remaining undifferentiated cells, plants carry "pockets" of undifferentiated material throughout their lifetime. Where are these "pockets" of undifferentiated cells found in a 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.
