C. The Monocot Root
1. Examine the x. s. of a young Zea mays root. Its parts are basically the same as those of a
dicot root.
2. Note the distinct appearance of endodermis with its Casparian strip. The xylem is
multi-lobed with large metaxylem cells. What type of stele does it exhibit?
D. Metamorphosed Roots
1. Below are plants with metamorphosed roots. Familiarize its adaptive features and
corresponding functions.
Species
Pandanus
Ficus elastica
Piper loberi
Ipomoea batatas
Raphanus sativus
Chlorophytum
Taeniophyllum
Rhizophora
Adaptive features
Functions
2. Observe the species in your surroundings, take a picture of at least three plant species
with modified stems, describe the adaptive features and indicate the non typical
function performed
3. Complete the table provided on your worksheet
