QUESTION 1
Study specimens Aand Bcarefully and use them to answer questions 1(a) to 1(e).
(a) Classify specimen B into its Division and Class. [2 marks]
(b) (i) State the types of leaf arrangements in specimens A and B. [2 marks]
(ii) Name the leaf shape of specimens A and B. [2 marks]
(c) (i) State the type of leaf margin in specimen A. [1 mark ]
(ii) State the types of venation found in the leaves of specimens A and B. [2 marks ]
(d) (i) List three observable similarities found in specimens A and B. [3 marks ]
(ii) In a tabular form, state four observable differences between specimens A and B. [4 marks]
(e) Make a drawing 8 cm – 10cm long of the leaf of specimen A and label fully. [9 marks]
Observation
Most candidates could not classify specimen B/twig of Ixora plant into its Division and Class and many that tried could not spell correctly. Most candidates could not answer questions (b) (i) and (ii); (c) (i) and (ii) correctly.
Many candidates could state observable similarities in specimens A and B quite well.
Only a few of the candidates’ drawings were good in question 1(e). Many candidates drew without putting the title of the diagram, the magnification and labelled correctly.
The expected answers are:
• (a) (i) Division
Angiospermatophyta/Angiospermophyta/Magniliophyta
(ii) Class
Dicotyledoneae/Magniliopsida
(b) (i) Types of leaf arrangements
Specimen A - Alternate/Spiral
Specimen B - Decussate/Opposite
(ii) Leaf shape
Specimen A - Lanceolate/Sword-like
Specimen B - Oval/Ovate
(c) (i) Type of leaf margin of specimen A
Entire/Smooth/Wavy
(ii) Types of venation found in Specimens A and B
Specimen A - Net/reticulate
Specimen B - Net/reticulate
Labels
Apex/tip; midrib/rachis/main vein; vein; margin/edge; leaf blade/lamina; petiole/leaf stalk.
(d) (i) Observable similarities between Specimens A and B
- Leaves have leaf stalk/petiole/petiolate;
- Leaf stalk/petiole swollen at the base;
- Leaves contain chlorophyll/are green in colour;
- Leaves have entire/smooth margins;
- Leaves have net/reticulate venation;
- Leaves have pointed apex;
- Leaves have prominent midrib;
- Both leaves are simple.
(ii) Observable differences between Specimens A and B
- Specimen A (mango)
- Petiole/leaf stalk is long
- Leaves have elongated apex/accuminate/acuminate
- Leaves have a narrow lamina/leaf blade
- Spiral/alternate leaf arrangement
- Leaves are bigger
Specimen B (Ixora)
- Petiole/leaf stalk is short;
- Leaves have short apex/acute;
- Leaves have a broad lamina/leaf blade;
- Decussate/ opposite leaf arrangement;
- Leaves are smaller;
Penalty: minus (-) 1 mark for no tabulation.
(e) Drawing/Diagram of leaf of specimen A
