Tissues : Meristematic and permanent tissues
- Pro Meristems can be distinguished from primary
meristem by
(a) Their apical position
(b) By their power of active division
(c) The presence of large prominent nucleus
(d) All the above - Meristematic cells are
(a) Thin walled, isodiametric, nucleate and less
protoplasmic
(b) Thin walled, isodiametric, nucleate and
densely protoplasmic
(c) Thin walled, isodiametric, non- nucleate and
densely protoplasmic
(d) Thick walled, isodiametric, nucleate and less
protoplasmic - The root apical meristem is sub apical because it
(a) Is covered by root hair
(b) Is covered by root cap
(c) has many corpus cells
(d) Is covered by tunica cells - Intercalary meristems are derived from
(a) Permanent tissues
(b) Secondary meristem
(c) Lateral meristem
(d) Apical meristem - Secondary meristem are derived from
(a) Apical meristem
(b) Intercalary meristem
(c) Lateral meristem
(d) Permanent tissues
6. Grass stem elongates by the activity
(a) Cambium (b) Intercalary meristem
(c) apical meristem (d) primary meristem
7. Which new tissues of plant body originate in the
apical meristem
(a) Parenchyma (b) Collenchyma
(c) Sclerenchyma (d) secondary
8. During the formation of leaves and elongation of
stem,some cells ‘left behind’ from shoot apical
meristem constitute the
(a) Lateral meristem (b) vascular cambium
(c) axillary bud (d) basal meristem
9. Primary growth of a tree occurs due to
(a) The activity of apical meristem
(b) The activity of vascular cambium
(c) The activity of root cap
(d) Only during the first year of tree’s life
10. Secondary meristem are set apart from primary
meristems in that they
(a) Are responsible for secondary growth
(b) Increase in the size of state
(c) Forms the cork and secondary vascular tissue
(d) Always formed from the permanent tissue
Epidermal, ground and vascular tissue- Multilayered epidermis occurs in
(a) Nerium leaf (b) maize leaves
(c) Oat leaves (d) hydrilla leaves - Chlorenchyma cells are
(a) Chlorophyll-containing sclerenchyma cells
(b) Chlorophyll-containing epidermis
(c) Chlorophyll-containing parenchyma
