III.Rapid growth occurs in response to high ABA - ANSWER ✔✔I and
II
Which of the following hormone -- function pairs are correct?
I.Auxin - phototropism
II.Cytokinin - regulates cell division
III.ABA - inhibits germination
IV.Ethylene - triple response - ANSWER ✔✔I, II, III, and IV
Plant cuticles and reptile scales both prevent dessication. Although
these two structures have similar function, plants and reptiles do not
share a terrestrial common ancestor. This is an example of -
ANSWER ✔✔convergent evolution
What are some functions of the shoot system? - ANSWER
✔✔Photosynthesis, support leaves, height, transport sugar and water
Which of the following are TRUE for hormones found in BOTH plants
and animals?
,I.Can interact with other hormones
II.Can be gasses
III.Can have multiple effects
IV.Can be antagonistic to other hormones
V.Require high concentrations - ANSWER ✔✔I, II, III, and IV
Functions of dermal tissue - ANSWER ✔✔Protection, prevention of
water loss, water absorption at root hairs
Functions of ground tissue - ANSWER ✔✔photosynthesis, storage,
support, short distance transport
Functions of vascular tissue(plants) - ANSWER ✔✔transport and
structural support
Xylem - ANSWER ✔✔vascular tissue that carries water upward from
the roots to every part of a plant
cohesion-tension hypothesis - ANSWER ✔✔transpiration and water
cohesion pull water from shoots to roots
Phloem - ANSWER ✔✔carries sugar and organic substances
throughout a plant, translocation of sugars from source to sink

, pressure-flow hypothesis - ANSWER ✔✔pressure gradient exists
between source where sugar is loaded into phloem (high pressure) and
sink where sugar is removed from phloem (low pressure)
plasmodesma - ANSWER ✔✔an open channel through the cell wall
that connects the cytoplasm of adjacent plant cells, allowing water, small
solutes, and some larger molecules to pass between the cells; continuity
between 2 cells
indeterminate growth - ANSWER ✔✔growth occurs throughout the
plant's life
primary growth - ANSWER ✔✔Growth produced by apical meristems,
which lengthen stems and roots
secondary growth - ANSWER ✔✔Growth produced by lateral
meristems, thickening the roots and shoots of woody plants
antagonistic hormones - ANSWER ✔✔hormones that have opposing
physiological properties, but that work together
Scientists have discovered a parasitic fungus whose hyphae invade
plants by piercing the cuticle on leaves. Which of the following best
describes the most immediate effect of the fungus on the plant?
a. Materials will move between adjacent cells less efficiently
