Summary Introduction
Introduction: The phloem is a complex tissue present in vascular plants. The soluble organic compounds synthesized during photosynthesis are transported by the phloem. It is also responsible for the transport of food materials from leaves to other plant portions. Companion cells, phloem fibers, phloem parenchyma, and sieve tube elements are the elements of the phloem.

- Guard cells surround stomata on the surface of leaves. A new herbicide targets the function of guard cells and prevents them from becoming flaccid and closing the stomata. What effect would the herbicide have on plants? a.Plants would dry out because guard cells protect the epidermis against desiccation. b.Plants would be eaten because guard cells protect leaves against herbivores. c. Plants would dry out because stomata would not be able to close. d.lt would regulate the intake of minerals in the plants.arrow_forwardGuttation in plants is due to condensation of water vapor and occurs through the hydathodes. D. Disagree, because guttation occurs through the stomates. A. Agree, because guttation occurs through the hydathodes. B. Disagree, because it is root pressure that causes guttation. C. Agree, because during night time, water condenses due to drop in temperature.arrow_forwardThe structure of the C4 leaf shows a. how mesophyll cells hug the epidermis of the leaf. hug the bundle sheath cells. b.
