Plant Seeds

These can come in different shapes, sizes and colours that can help in the identification of similar seeds.

Seeds may be enclosed within their fruit when bought from a shop, such as sunflower 'seeds'. They can also have attachments which aid seed dispersal (e,g, dandelion), hairs, propellers (e.g. maples), hooks (e.g. burdock), awns (e.g. some grasses) or may be 'sticky' (e.g. cleavers).

Seed weight and number can range from many seeds per gram of weight to a single seed of the Palm tree (Coco de Mer) which weighs in at around 20kg.
