Mars Sample Contains Wood Cell Remains.

Added on July 19, 2021: Why they are wood cell remains

1. Red arrows point to cross section of wood cells. Compare them with Earthly wood cells at [link to www.flickr.com (secure)]

2. Red arrows point to particles that are the sizes of sand grains (see [link to www.flickr.com (secure)] ), which are between 62 and 2,000 micrometers across. However, no sand grains show the morphology of these particles.

3. Only plant life has such cells.

That's wood, alright.

That little rover best start looking for some firewood. Martians winters are long and cold.

Check out youtube hangman51010 to see he wood remains on earth, of giant trees

I trust red arrows labelled 'wood cells' more than the chemical analysis performed!
