Both apical meristems and intercalary meristems:-
I. Are primary meristems
II. Appear early in plant life
III. Contribute to the formation of the primary plant body

1. Only I and II are correct
2. Only I and III are correct
3. Only II and III are correct
4. I, II and III are correct

During secondary growth in the stem:-

1. The amount of secondary xylem produced is more than the secondary phloem as the
cambium is generally more active on the inner side than the outer.

2. the amount of secondary phloem produced is more than the secondary xylem as the cambium is generally more active on the inner side than the outer.

3. the amount of secondary xylem produced is more than the secondary phloem as the cambium is generally more active on the outer side than the inner.

4. the amount of secondary phloem produced is more than the secondary xylem as the cambium is generally more active on the outer side than the inner.

In temperate region plants, the wood with fewer xylary elements and narrow vessels, is termed as:-

1. Spring wood
2. Autumn wood
3. Sap wood
4. Heart wood

Parts of grasses removed by the grazing herbivores are regenerated due to the activity of: 

1. Apical meristem

2. Intercalary meristem

3. Interfascicular cambium

4. Fascicular vascular cambium

Identify the wrong statement in context of heartwood.

(1) Organic compounds are deposited in it

(2) it is highly durable

(3) It conducts water and minerals efficiently

(4) It comprises dead elements with highly lignified walls

The vascular cambium normal gives rise to.

(1) phelloderm                                         

(2) primary phloem

(3) secondary xylem                                 

(4) periderm

Which one of the following comprises only simple tissue?

1. Parenchyma, Collenchyma and Sclerenchyma

2. Parenchyma, Xylem and Collenchyma

3. Parenchyma, Xylem and Sclerenchyma

4. Parenchyma, Xylem and Phloem

Match the following

A. A-i, B-iii, C-v, D-ii, E-iv

B. A-iii, B-i, C-ii, D-v, E-iv

C. A-ii, B-iv, C-v, D-i, E-iii

D. A-v, B-iv, C-iii, D-ii, E-i

What is the destiny of primary xylem in a dicot root showing extensive secondary growth?

1. It is retained in the centre of the axis

2 It gets crushed

3. May or may not get crushed

4. It gets surrounded by primary phloem

Anatomically fairly old root is distinguished from dicotyledonous stem by

1. Position of Protoxylem

2. Absence of secondary xylem

3. Absence of secondary phloem

4. Presence of cortex
