Draw labelled diagram to show the following parts in an embryo of a pea seed :
Cotyledon, Plumule, Radical
Answer
Draw the pea embryo with two cotyledons, the plumule between them and the radicle as the projecting pointed tip.
Labelled diagram of the embryo of a pea seed (see the figure): two cotyledons (the seed leaves, which store food) are attached to a small embryo axis; the upper end of the axis is the plumule (the future shoot, with tiny leaves), lying between the cotyledons, and the lower end is the radicle (the future root, printed 'Radical'), a pointed tip that projects out of the seed.
