Five practice questions, worked

Original questions written to this exam's published syllabus and pattern. Not past papers.

1. Lignin in the secondary wall makes it:

  1. Soft and elastic
  2. Water-soluble
  3. Photosynthetic
  4. Rigid and decay-resistant
Answer and working

D. Rigid and decay-resistant

Lignin stiffens and protects walls; wood is mostly lignified secondary walls.

Forest Botany & Plant Systematics · Plant cell, tissues and secondary growth

2. Bengal kino, a red exudate, comes from:

  1. Acacia senegal
  2. Pinus roxburghii
  3. Ficus religiosa
  4. Butea monosperma
Answer and working

D. Butea monosperma

Butea yields Bengal kino; Acacia senegal gum arabic; chir pine resin; Ficus latex.

Dendrology & Tree Identification · Field characters: bark, blaze, leaf arrangement, stipules, exudates

3. Compared with shade-intolerant species, shade-tolerant tree species typically have:

  1. Higher light-saturated photosynthesis and higher respiration rates
  2. Lower dark respiration and lower light compensation points
  3. Thicker leaves with more palisade layers and lower specific leaf area
  4. Shorter leaf life spans and faster height growth in open sites
Answer and working

B. Lower dark respiration and lower light compensation points

Shade tolerance is linked to a low carbon cost of maintenance and positive carbon balance at low light; high Amax, thick sun-type leaves and fast growth in the open describe light-demanding pioneers.

Tree Physiology · Photosynthesis in trees: C3 pathway, light response, shade tolerance

4. Grey or bluish colours with rusty mottles in a subsoil indicate:

  1. High organic matter content
  2. Calcium carbonate accumulation
  3. Recent volcanic ash deposits
  4. Gleying from waterlogging
Answer and working

D. Gleying from waterlogging

Reduction of iron under saturation gives grey colours; reoxidation where the water table fluctuates forms rusty mottles.

Forest Soils & Soil Conservation · Soil-forming factors and processes under forest

5. The average rate at which air temperature falls with height in the troposphere is about:

  1. 9.8 °C per km
  2. 1.0 °C per km
  3. 15 °C per km
  4. 6.5 °C per km
Answer and working

D. 6.5 °C per km

The environmental lapse rate averages 6.5 °C per km; 9.8 °C per km is the dry adiabatic rate for rising unsaturated air.

Forest Meteorology & Climatology · Atmosphere, radiation balance and energy budget
