Plants constantly grow in specialized areas only!
pericyclepericycle
First root grows straight down ex. Beet
Grow from lower nodes of stem
Anchor/ hold soil ex. grss
Dicots- from vascular tissue
Secondary growth
Soybean root nodules, each containing billions of Bradyrhizobium bacteria
Produces new cellsthat elongate, increasing length
Continually differentiating
Terminal bud
Primary growth
