Kidney bean is an annual herbaceous plant. The stem is erect, green in colour, ribbed, cylindrical and solid. Plant not more than 60 cm in height (determinate bush type). Stem nodes are few (6-8 in number).
Answer:
A. The leaves are broad at the blade and are attached to the stem by means of a stalk-like
petiole. The leaf may be simple (have only one blade per petiole) or compound (usually
three blades per petiole). There may be two simple leaves or one compound leaf
attached at a spot on the stem called a node. The veins of each leaf blade are arranged
into a complicated network.
B. The bean stem is quite long and the internodes between leaf attachments (nodes) are quite
obvious. The lowest portion of the stem is below the cotyledons and is called the
hypocotyl. The stem terminates at the top of the plant in the apical bud. Lateral buds
are found in the axils of each leaf just above the node.
C. The roots of the bean plant are mostly fibrous, although a single main root (the taproot) is
larger than the others. The taproot forms many fine lateral roots that make up the bulk of
the mineral absorption area.
