During germination the radicle and the plumule develop into, respectively:

1. The radicle and plumule are the two growing parts of the seed embryo. 2. The radicle emerges first and grows downwards to become the root. 3. The plumule grows upwards to become the shoot. 4. The seed coat is the testa, a protective layer rather than a growing part. 5. The food store is the cotyledon, which supplies the embryo until the seedling can photosynthesise. _Source: NECTA CSEE 2022 Biology 033, Question 1: Multiple Choice Items, item (v)_
