Xilema

Xilema é o tecido vivo em plantas vasculares cuja função básica é transportar água com nutrientes (a chamada seiva bruta) das raízes para os caules e folhas.^[1]^[2]

A palavra "xilema" é derivada da palavra grega ξύλον (xylon), que significa "madeira"; o tecido de xilema mais conhecido é a madeira, embora seja encontrado em toda a planta.^[3] O termo foi introduzido por Carl Nägeli em 1858.^[4]^[5]

O xilema é um dos dois tipos de tecido de transporte nas plantas vasculares, sendo o outro o floema (que transporta a seiva elaborada). O transporte xilémico é o mais rápido nas plantas podendo atingir, em dias de verão, em media 60 cm/min
