Unit 5: Plant Study Guide Answers

The sun- ultimate source of energy Energy of life- required for growth, reproduction, movement, and transport of materials across membranes The sun- ultimate source of energy Photosynthesis- process whereby plants capture energy and make complex molecules Light reaction Produces- ATP/NADPH and oxygen Location- thylakoid membranes Dark reaction Produces- glucose Location- stroma (fluid inside chloroplast) Role of chlorophyll- absorbs light energy Source of oxygen- water

Interior of stem- composed of vascular tissue (xylem and phloem) Photosynthesis Equation: 6CO2 + 6H2O  C6H12O6 + 6O2 Cellular respiration Equation: C6H12O6 + 6O2  6CO2 + 6H2O Glycolysis- glucose is split, pyruvic acid is made, some ATP is produced Fermentation- process where organic molecules are broken down in the absence of oxygen Electron transport chain of CR- where most of the ATP (energy) is made Interior of stem- composed of vascular tissue (xylem and phloem) Plant cells Collenchyma- specialized for support Parenchyma- plants soft, primary growth; pliable, thin walled Sclerenchyma- provides structural support; dead at maturity Meristems- regions of active cell division; found at tip of stem and root

Primary growth- lengthening of plant Secondary growth- width of plant Endodermis- regulation of passage of water and minerals into the vascular tissue Cortex- outermost layer consisting of ground tissue in a stem Phloem- transports sugar Xylem- transports water Mature ovary- fruit of the plant
