2c. Specimen F, Panicum plant/Guinea grass, has a fibrous root system.
II. Specimen G(The cocoyam plant has a fibrous root system.

2d. Wait for it.

2e. Specimen F, Panicum plant/Guinea grass, is of economic importance in the following ways:
1. It is used as a forage crop for livestock.
2. It is used as a cover crop to prevent soil erosion.
3. It is used as a biofuel crop to produce ethanol.

2fi. Four observable features of the cocoyam corm (specimen H) are:
1. It is a modified stem that is swollen and fleshy.
2. It has a brown, rough outer layer and a white, starchy inner layer.
3. It has several small, circular depressions on its surface where the roots emerge.
4. It has a pointed top where the stem emerges.
