Avocado: Taproot emerges

Today I am down with a cold or something. I'm feeling pretty terrible, so I am staying home in the morning hoping that I can get better and head off to work later today.

Today I noticed that my avocado has grown a taproot in the past week. A taproot is the large root that grows straight down and will anchor the seed as it grows in the first stages of its life. Later. the root system will grow sideways and provide a wide area which the avocado will use to absorb rainwater. Right now, it's sitting in water, so it's happy as a clam.

In the last week, the root has gone from a little nub in the middle of the seed to an easily recognizable root feature almost 4cm in total length. The root extends past the seed about 1 centimeter. In a few more weeks, the root will grow even longer with more root fibers.
