    What is the significance of the experiment by Ruben and Kamen?

    It showed that oxygen produced comes from water.

    What are the main products of photosynthesis?

    Glucose and oxygen are produced.

    What happens during the photochemical phase of photosynthesis?

    Water is oxidized, producing oxygen and energy carriers.

    What is the function of NADPH in photosynthesis?

    It donates electrons for glucose production.

    What is the cycle of Calvin?

    It describes the biochemical reactions during the chemical phase of photosynthesis.

    What is the role of glucose in plant growth?

    It serves as a precursor for various organic molecules.

    What are meristems?

    They are regions of active cell division in plants.

    How do roots and shoots differ in growth?

    Roots grow through cell division and elongation, while shoots form various organs.

    What is a phytomere?

    It is a structural unit of a plant consisting of a stem segment and associated organs.

    What are the two types of vascular tissues in plants?

    Xylem conducts water, while phloem transports organic substances.

    It carries water and minerals from roots to other plant parts.

    What does the phloem transport?

    It distributes organic compounds produced by photosynthesis.

    What is the importance of the chlorophyll pigment?

    It captures light energy for photosynthesis.
