Section A · multiple choice
- 1.

- intercalary meristem
- primary meristem only
- apical meristem
- lateral meristem (vascular cambium and cork cambium)
Answer
(d) lateral meristem (vascular cambium and cork cambium)
- 2.
Sclereids are:
- short dead lignified cells found in nut shells and the pulp of guava
- dividing tissue at the root and shoot tips that makes the plant longer
- sclerenchyma of the phloem, used for jute and flax
- living phloem cells without a nucleus, joined by sieve plates
Answer
(a) short dead lignified cells found in nut shells and the pulp of guava
- 3.
A section shows more than six radial xylem bundles (polyarch) and a large, well-developed pith. It is a section of a:
- monocot stem
- dicot root
- monocot root
- monocot leaf
Answer
(c) monocot root
Section B · short answer
- 4.
What is the difference between an apical and an intercalary meristem?
Answer
An apical meristem is at the tips of roots and shoots and makes the plant longer. An intercalary meristem is between mature tissues, at the base of grass internodes, and helps regrow parts removed by grazers.
- 5.
Name the tissue: nucleated phloem cells that keep the sieve tubes working.
Answer
Companion cells
Section C · long answer
- 6.
Compare the internal structure of a dicot root and a monocot root.
Answer
Dicot root: 2–4 xylem bundles (diarch to tetrarch), small or no pith, cambium forms later and secondary growth occurs. Monocot root: more than six xylem bundles (polyarch), large well-developed pith, no secondary growth. Both have epidermis with root hairs, cortex, endodermis with Casparian strips, pericycle and radial exarch vascular bundles.
