polysaccharide
Turgor pressure is what allows a blade of grass to stand up straight. This is a type of a molecule.
polysaccharide
This is the stem.
Cellulosecellulose
Cellulosecellulose
Cellulose, lignin, hemi-cellulose and fibres are all molecules in the structure of the plant cell wall that makes the plant (in this case a blade of grass) stand up straight. Polysaccharide
The part of the blade grass that allows it to stand up is primarily the culm, which is the hollow stem of the grass. The rigidity and strength of the culm provide structural support, allowing the grass to grow upright. Additionally, the arrangement of leaves and the plant's overall morphology contribute to its ability to remain erect, even in windy conditions.
This question is unanswerable as it depends on which type of grass you mean.
a blade of grass weigh a gram? Not normal grass anyway, weigh much less

It is unlikely that a blade of grass can kill you in a tornado. Tornadoes are dangerous due to their strong winds and debris, but a single blade of grass would not pose a significant threat to your safety during a tornado.
