Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which type of meristem tissue is located between the bark and the wood of a woody stem?
A
xylem
B
vascular cambium
C
apical meristem
D
cork cambium
Explanation: 

Detailed explanation-1: -The cork cambium also is a secondary meristem, containing meristematic cells. The cork cambium forms a major portion of the bark of woody plants.

Detailed explanation-2: -The vascular cambium is the main meristem in the stem, producing undifferentiated wood cells inwards and bark cells outwards.

Detailed explanation-3: -The inner cells of bark, known as phloem, grow by the division of outer cells in a generative layer called the vascular cambium, located between the bark and wood (inner cells of this cambium produce xylem cells).

Detailed explanation-4: -C: The cambium cell layer is the growing part of the trunk. It annually produces new bark and new wood in response to hormones that pass down through the phloem with food from the leaves. These hormones, called “auxins”, stimulate growth in cells.

Detailed explanation-5: -The vascular cambium and the cork cambium are good examples of a lateral meristematic tissue.
