This type of growth is called _?__ • Apical meristems; primary Next Question Plant Growth – 20 points • A name for the areas of unspecialized cells in which mitosis occurs • Meristems Next Question Plant Growth – 30 points • What allows vascular plants to grow taller than non-vascular plants? • Cell walls of vascular tissue are hardened by lignin Next Question Plant Growth – 40 points • _?_ describes the growth of a shoot (or stem) toward the light. The hormone involved in this response is called _?_ • Positive phototropism; auxin Next Question Plant Growth - 50 points • Hormones that stimulate cell elongation are called _?_; these hormones are responsible for __?__ (responses to environmental stimuli) • Auxins; tropisms Next Question Roots – 10 points • This structure is made of protective cells and is found at the very tip of a root • Root cap Next Question Roots – 20 points • Root surface area is increases when there are many __?__ present • Root hairs Next Question Roots – 30 points • Is this a monocot or a dicot? • dicot Next Question Roots – 40 points • What is the layer of red in this monocot root called? • Endodermis ?? Next Question Roots– 50 points • What is the structure on this dicot root indicated by the ?? • Xylem ?? Next Question Stems– 10 points • One of the main function of stems is __?__ • Carry water and nutrients; support; storage (any one) Next Question Stems– 20 points • Monocot or dicot? What structure is ??? • Dicot; Vascular bundle Next Question ??? Stems – 30 points • The outer protective layer of a plant is called ???; it is covered by the __?__ which protects it from drying out • Epidermis; cuticle ??? Next Question Stems – 40 points • Monocot or Dicot? How do you know? • Monocot; vascular bundles are scattered throughout stem Next Question Stems – 50 points • Some stems will wrap around an object to climb it. Ex: Ivy. What is the name of this plant response? • Thigmotropism Next Question Leaves – 10 points • Which number is referring to the cuticle? Spongy mesophyll? Guard cell? • 1, 4, 7 Next Question Leaves– 20 points • Is this leaf a monocot or a dicot? How do you know? • Dicot; its parenchymal cells are differentiated into palisade and spongy mesophyll Next Question Leaves – 30 points • In which layer of a leaf would you be most likely to find the highest number of chloroplasts? • Palisade Mesophyll Next Question Leaves – 40 points • From which structure is water lost during transpiration? • Stoma (Stomata) Next Question Leaves – 50 points • What is a leaf vein? • The vascular cylinder (xylem and phloem) Next Question Final Jeopardy Round 2 CohesionTension Theory Pressure Flow Model Plant Hormones & Responses Flowers and Seeds Miscellaneous 20 20 20 20 20 40 40 40 40 40 60 60 60 60 60 80 80 80 80 80 100 100 100 100 100 Cohesion Tension Theory – 20 points • _?_ lowers the pressure in the leaf xylem, creating a vacuum that pulls water upward in a plant • Transpiration Next Question Cohesion Tension Theory – 40 points • Cohesion is the result of __?__ between water molecules • Hydrogen Bonds Next Question Cohesion Tension Theory– 60 points • __?__ is important because it can conduct water and nutrients over long distances • Xylem Next Question Cohesion Tension Theory– 80 points • Name 2 properties of water that, along with transpiration, allow water to flow upward against gravity • Adhesion, cohesion Next Question Cohesion Tension Theory– 100 points • Name the two types of xylem cells AND give an unusual trait which they both have • Tracheids and vessel elements; they are dead at maturity Next Question Pressure-Flow Model – 20 points • The pressure-flow model explains the movement of _?_ through a plant • Sugar Next Question Pressure-Flow Model – 40 points • When a plant moves sugars from the leaves to it’s roots, the leaves are the __?__ while the roots are the __?__ • Source, sink Next Question Pressure-Flow Model – 60 points • _?_ between companion cells and sieve tube elements allow them to communicate with each other • plasmodesmata Next Question Pressure-Flow Model – 80 points • Why is water involved in the movement of sugars? • What must flow out of xylem into phloem to increase the pressure there; that is what makes sugar flow Next Question Pressure-Flow Model– 100 points • True/False Questions: Sugars can move up, down, laterally in plants _?_; When water flows out of xylem into phloem, pressure decreases _?_ • T; F Next Question Plant Responses/Hormones – 20 points • The hormone that produces increases in size (especially in length of stems) • Gibberellins Next Question Plant Responses/Hormones– 40 points • Fruit ripening is stimulated by the hormone _?_ • ethylene Next Question Plant Responses/Hormones– 60 points • The plant response to touch is called _?_ • thigmotropisms Next Question Miscellaneous– 80 points • What happens during double fertilization? • 1 sperm joins with an egg making the embryo; 1 sperm joins with 2 polar nuclei making the 3n endosperm Next Question Miscellaneous – 100 points • Name the 2 types of lateral meristems and tell what they produce • Vascular cambium – secondary xylem and phloem and cork cambium – cork (bark) Next Question Flowers and Seeds – 20 points • Describe a seed that you would expect animals would disperse • Burrs (caught in fur) or fruits (eaten and then dispersed) Next Question Flowers and Seeds – 40 points • The period during which an embryo is not growing is called _?_.
