Did you know Plants are Actually Single Celled Organisms? Plasmodesmata

Plant cells are connected at the hip with membrane tubes called plasmodesmata. So most plants are *technically* one cell since they have a single continuous membrane.

You may be thinking back to high school biology and wondering how that’s possible! You studied the plant cell!

Songs You May Have Missed #825

Pluto Gang: “Plasmodesmata” (2020) Having had their first regional tour interrupted by the COVID pandemic, Carolina sextet Pluto Gang convened in a cabin in the Carolina mountains to create their genre-blurred Better Out Here LP, Their sound is something the band calls “high energy jam soul”. Works for me.

Plant cells are interconnected by cytoplasmic bridges called plasmodesmata (see Chapter 1), cylindrical pores 20 to 60 nm in diameter (Figure 6.18 and Figure 1.6).

Biologists Find Glutamate-Based Long-Distance Signaling Is Rapid In Plants

With the Arabidopsis as an example, a team of researchers showed that systemic signals in plants begin with the release of glutamate, which is perceived by glutamate receptor-like ion channels. The ion channels then set off a cascade of changes in calcium ion concentration that propagate through the phloem vasculature and through intercellular channels called plasmodesmata. This glutamate-based long-distance signaling is rapid.
