Resource summary

Question 1

Question
Sites of rapid cell division in the shoot tips, root tips, and cambium are called [blank_start]meristems[blank_end]
Answer
  • meristems

Question 2

Question
Meristems located at the end of the shoots are called [blank_start]primary[blank_end], or [blank_start]apical[blank_end] meristems.
Answer
  • primary

Question 3

Question
The tendency for terminal buds to inhibit the growth of lateral buds is called [blank_start]apical dominance[blank_end].
Answer
  • apical dominance

Question 4

Question
The "food factories" of trees are the [blank_start]leaves[blank_end].
Answer
  • leaves

Question 5

Question
The process of [blank_start]photosynthesis[blank_end] combines carbon dioxide and water in a reaction driven by light to produce sugars. [blank_start]Oxygen[blank_end] is also a product of this reaction.
Answer

Question 6

Question

Answer
  • chlorophyll

Question 7

Question
[blank_start]Transpiration[blank_end] is the loss of water vapor from the leaves.
Answer
  • Transpiration

Question 10

Question

Question 11

Question

Question 12

Question

Question 14

Question
Water enters young roots or mycorrhizal roots, in part, by a process called [blank_start]osmosis[blank_end].
Answer
  • osmosis

Question 15

Question
The orientation of growth in response to an external stimulus is called [blank_start]tropism[blank_end]. Two examples are [blank_start]geotropism[blank_end] and [blank_start]phototropism[blank_end].
Answer
  • tropism
  • geotropism
  • phototropism

Question 16

Question
CODIT stands for [blank_start]compartmentalization[blank_end] [blank_start]of[blank_end] [blank_start]decay[blank_end] [blank_start]in[blank_end] [blank_start]trees[blank_end].
Answer
  • compartmentalization
  • of
  • decay
  • in
  • trees

Question 17

Question
Trees with upright growth and a strong, central leader are said to exhibit [blank_start]excurrent[blank_end] growth. More rounded trees, which are often broader than they are tall, have [blank_start]decurrent[blank_end] growth habits.
Answer
  • excurrent
  • decurrent

Question 18

Question
Roots and fungi form [blank_start]mycorrhizae[blank_end], which are a symbiotic relationship, aiding in the uptake of water and minerals.
Answer
  • mycorrhizae

Question 19

Question
The process by which chemical energy, stored as sugar and starch, is released is called [blank_start]respiration[blank_end].
Answer
  • respiration

Question 20

Question
