Concept explainers
To differentiate: Between vascular cambium and cork cambium.
Introduction: In plants, the growth occurs throughout their life. This is because in plants, the meristems are present. These meristematic cells divide continuously and lead to the formation of new cells, which are further elongated and differentiated. The secondary growth of the plant tissues that arises at cylinders of the lateral meristem runs lengthwise through older stem and roots. Vascular cambium and cork cambium are the two lateral meristems.
To determine: The tissues that arise from vascular cambium.

- 5) Match the tissue name on the left with the description that best matches the structure of cells making up that tissue on the right: a) collenchyma cells are round, have very thin walls, and are alive at maturity. b) phloem cells have relatively few organelles and are hollow. c) parenchyma cells have thin walls and sometimes secrete a waxy substance. d) xylem cells have thick secondary cell walls reinforced with lignin. e) epidermis cells are long with a primary cell wall that is thickest at the ends of the cell, but no secondary cell wall. f) periderm cells are long and thin, hollow, with pits lining the sides of the cells. g) sclerenchyma some cells of this tissue have thick cell walls, whereas other cells of this tissue do not. 6) Match the tissue on the left with the description of the function it generally performs for the plant on the right: a) phloem flexible support, such as in petioles and herbaceous stems. b) xylem forms an outer barrier for leaves, young stems and roots.…arrow_forwardIt was previously stated that parenchyma cells are relatively inexpensive to build. What does that mean? How does this relate to most leaves being soft?arrow_forwardWhat are the two types of mechanical, nonconducting sclerenchyma? Which tends to be flexible and useful in wood? Which tends to be brittle and inflexible, useful in “pits” and “stones” that protect seeds?arrow_forward
