Chapter 7, Problem 1FIB
Summary Introduction
Introduction: Photosynthesis is the process of generating high-energy sugar molecules and oxygen from water and carbon dioxide in the presence of sunlight. This process takes place in leaves where the exchange of carbon dioxide and oxygen occurs in a plant.

- Most of the carbon that land plants use for photosynthesis comes from ______. a. glucose b. the atmosphere c. water d. soilarrow_forwardT/F Question Parenchyma is soft, internal plant tissue. Xylem and phloem are plant structural tissue. Periderm tissue is a type of plant epidermis in young stems and roots. Plant shoots include stems, leaves, and flowers. Monocot stems have their vascular bundles arranged in a ring pattern in the ground tissue. Eudicots have their leaf veins arranged in a parallel pattern. Photosynthesis in leaves takes place in the mesophyll layer Eudicots possess a large taproot. The limiting factor for plants is phosphorus. Root hairs help to decrease the absorbtive surface area of a plant. Xylem conducts plant sugars and organic molecules. Plant tissues grow from meristem cells that continually divide during the growing season. Primary plant growth involves thickening of the stems and roots. Plants can undergo asexual reproduction without cross-pollination. The fertilization process in plants is a double fertilization process. Over 1/3 of the U.S. food supply comes from the cross-pollination…arrow_forwardOpenings in the plant body to allow for gas exchange are termed palisade cells collenchyma stomata spiraclesarrow_forward

Jamil: The phloem is needed for cellular respiration as it transports the carbon dioxide to the leaves in order to perform cellular respiration. Shantal: The cambium is important for phossynthesis because it allows water into the plant which is needed as a reactant for photosynthesis. Enrique The guard cells are needed during transpiration because they open and close to regulate the gases that enter and leave the plant.
