Specialized Stem Types

Question 1

The shoot consists of a small amount of vertical stem tissue (bearing roots below) and a massive quantity of thick, fleshy leaves

Answer 1

Bulb

Question 2

The shoot consists mostly of generally globose stem tissue surrounded by scantly, scale life leaves​

Answer 2

Corm

Question 3

In which the rootstock consists of relatively undifferentiated but vertically oriented stem​

Answer 3

Caudex

Question 4

The stem is horizontal and underground, typically with short internodes and bearing scale like leaves

Answer 4

Rhizome

Question 5

Underground storage stem, usually not upright, typically bearing outer buds and lacking surrounding storage leaves or protective scales

Answer 5

Tuber

Question 6

Long, slender stem that grows horizontally along the surface of the ground. New leaves and roots develop where a node touches a ground, and these are independent plant as soon as the runner dies

Answer 6

Runners

Question 7

Sharp pointed structures that are probably of survival value in decreasing the amount of browsing damage to these plants by herbivores and also by humans

Answer 7

Thorns and spines

Question 8

Long, thin, coiling structures, which attach the plant to a support. Due to unequal rates of growth, the tips of tendrils move slowly back and forth as they elongate

Answer 8

Tendrils

Question 9

Low, swollen, perennial storage stem (at or above ground level), from which arise annual or non-persistent photosynthetic shoots

Answer 9

Caudiciform

Question 10

Woody, trunk-like stem that is swollen basally, the swollen region functioning in storage

Answer 10

Pachycaul

Question 11

Flattened, needle like, photosynthetic stem that may resemble and function as a leaf; take over the primary photosynthetic function of leaves and may function to reduce water loss

Answer 11

Cladode
