The rice plant, species Oryza Sativa, is from the family Gramineae (Grass Family).
The plant has many different variations, but is generally a short living plant, with an average life span of 3-7 months, depending on the climate and the variety. It is not a water plant but substantial amounts of water are required for the planting. Cultivated species of rice are considered to be semi-aquatic annuals. The height of the plant can range from 0.4m to over 5m in some floating rices.
Rice is generally grown in paddy fields – fields that can be flooded to help the growing crop and drained prior to harvest. “Paddy” rice is rice in the form it is harvested. Each grain has many layers. The outer layer is the husk. The husk consists of 2 interlocked half shells. Each protects one half of the paddy. The husk is inedible and composed of silica and cellulose.
