The flow chart shows stages in the life cycle of a flowering plant.
The name of stage 5 of the life cycle has not been included in the flow chart.
During this stage a radicle and a plumule are formed from a seed.
State, in the correct place on the flow chart, the name of stage 5.
Describe the role of enzymes in this stage of the plant's life cycle.
Two of the stages in the life cycle of this flowering plant may depend on the action of an animal.
Identify each of these stages and for each stage describe how the action of an animal may be required.
stage ______
action of an animal ______
stage ______
