Forestry and Plant Sciences Questions
-
A bristlecone pine
-
An oak tree
-
A giant redwood
-
A California sequoia
A
Correct answer
Explanation
The oldest known tree in the United States is a bristlecone pine named Methuselah, aged over 4,800 years, located in California's White Mountains. While giant redwoods and California sequoias are the most massive trees, they're not the oldest. Oak trees, though long-lived, don't match bristlecone pines' extreme longevity in high-altitude environments.

Leaves
-
Flowers
-
Roots
D
Correct answer
Explanation
Roots are the one component that is ALWAYS present in and essential to a tree. While trees do have leaves, flowers, and fruits, these are not permanent - trees can be without leaves (deciduous trees in winter), without flowers (most of the year), or without fruits (before fruiting season). Roots are fundamental to the tree's existence.

D
Correct answer
Explanation
Grizzly tracks show a distinct rounded heel pad (the axe blade shape) with five toe prints arranged in a relatively straight row at the front. This differs from other animals whose toes might fan out more dramatically or have different pad configurations. The key identifier is that combination of the rounded main pad and five toe pads in a line.

A
Correct answer

Quinine is extracted from the bark of the cinchona tree native to South America. The cinchona bark has been the primary commercial source of quinine for malaria treatment since the 17th century. Redwood and eucalyptus are not sources of medicinal quinine.
A
Correct answer
Explanation
The proverb is 'A bad tree does not yield good apples.' It means that something negative cannot produce positive results - the source determines the quality of the output. A 'good' or 'average' tree wouldn't make sense in this context.
