EXERCISE 57 

 PRODUCTION OF A PLANT FROM A SEED 



Materials. Unroasted peanuts ; three-inch paraffined paper plant 

 pots; clean sawdust or sand. 



Directions for work. Let each pupil fill one of the pots with 

 sawdust or sand which has been thoroughly wet. Plant sev- 

 eral seeds in each one, and label the pot for proper identi- 

 fication. Set the po'ts aside in a dark place until the young 

 plants begin to appear above the surface of the ground. Plant 

 other seeds at intervals during the progress of the experiment 

 in order to assure having a few plants in early stages for com- 

 parison at all times. Keep a record of the growth of the young 

 plants by making drawings daily, or at shorter intervals if 

 growth is rapid. When the young plants are erect and the 

 first pair, of foliage leaves are well grown, dig up several of 

 them and make a drawing showing all parts, including the 

 roots. Carefully label all the parts of the young plant, using 

 the textbook to ascertain the proper names. 



Dig up some of the seeds that were planted later in order to 

 secure stages in the development of the plants before they have 

 come up. Complete your series of sketches. Using your draw- 

 ings as memoranda, write a connected story of the development 

 of a young plant from a seed.
