Five practice questions, worked

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

1. A 2000 ha oil palm estate has trees over 10 m tall and canopy cover above 60%. Under FRA definitions it is:

  1. Forest, because it exceeds every area, height and canopy threshold
  2. Not forest, because it is land predominantly under agricultural use
  3. Other wooded land, because palms are not true trees in botanical terms
  4. Planted forest, because all of the trees were established by planting
Answer and working

B. Not forest, because it is land predominantly under agricultural use

FRA excludes tree crops on agricultural land, such as oil palm, orchards and agroforestry with crops, even when they meet the cover and height thresholds.

2. In gymnosperm phloem, sieve cells are associated with:

  1. Albuminous cells
  2. Companion cells
  3. Vessel elements
  4. Collenchyma cells
Answer and working

A. Albuminous cells

Angiosperm sieve-tube elements have companion cells; gymnosperm sieve cells have albuminous cells.

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

3. Gum karaya comes from:

  1. Anogeissus latifolia
  2. Pterocarpus marsupium
  3. Sterculia urens
  4. Shorea robusta
Answer and working

C. Sterculia urens

Sterculia urens yields karaya; Pterocarpus marsupium a red kino; sal a resin.

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

4. A leaf cell has solute potential −1.2 MPa and pressure potential +0.5 MPa. Ignoring gravity and matric effects, what is its water potential?

  1. −1.7 MPa
  2. +0.7 MPa
  3. −0.7 MPa
  4. −0.6 MPa
Answer and working

C. −0.7 MPa

Ψ = Ψs + Ψp = −1.2 + 0.5 = −0.7 MPa. −1.7 subtracts the turgor; +0.7 reverses the sign.

Tree Physiology · Water relations: transpiration, cohesion-tension, xylem embolism

5. Which process dominates soil formation on old land surfaces in the hot, humid tropics?

  1. Podzolisation under acid conifer litter
  2. Ferralitisation: loss of silica and bases
  3. Calcification in dry, alkaline conditions
  4. Melanisation under dense grassland roots
Answer and working

B. Ferralitisation: loss of silica and bases

Intense weathering and leaching remove silica and bases, leaving Fe and Al oxides and kaolinite (Ferralsols, Oxisols).
