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.

Blade grass, like other flowering plants, primarily exists in the sporophyte stage of its life cycle. The sporophyte is the dominant phase, characterized by the production of seeds and flowers. The gametophyte stage is reduced and typically occurs within the reproductive structures of the sporophyte. Thus, blade grass is predominantly a sporophyte.
The portion of a leaf that wraps around the stem at the base of the blade on a grass plant is called the sheath. It helps to provide structural support to the leaf and connects it to the stem.
No, grass is not a molecule. Grass is a complex organism made up of various molecules such as proteins, carbohydrates, and chlorophyll. Molecules are combinations of atoms bonded together, while grass is a living plant composed of many different types of molecules working together.
No, sticking a blade of grass up your nose will not cause you to faint. However, it can irritate the nasal passages and potentially cause discomfort or a nosebleed. It's best to avoid inserting foreign objects into your nose.
To give a basic and broad perspective answer this is an example of common organism feeding patterns. ex: the water's cellular life base and the sun's rays help the, per say, blade of grass be nurtured, that same blade of grass either is eaten by an insect, a herbivore, or dies and withers to help nurture fungi in the forest. The insect who ate that blade of grass is perhaps later eaten by a frog. The frog, who ate the insect that had eaten the grass, is perhaps eaten by a bird of prey. The bird is possibly hunted and becomes our next meal or is killed off and eaten by a cougar. From there the cycle continues on to larger, voracious animals till it finally goes back to that single blade of grass.
Turgor pressure is what allows a blade of grass to stand up straight. This is a type of a molecule.
Chlorophyll is the molecule in a blade of grass that captures solar energy during photosynthesis.

The dew drop can fall of the tree and land carefully on the grass

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
This is somewhat more complicated than you might think. There are several sugar polymers, most specifically cellulose, that contribute structural rigidity to plant structures. However in many grasses microscopic crystals of silicon dioxide (i.e. quartz) are embedded in these polymers like steel rebar is embedded in concrete to give extra strength and rigidity to the blades of grass. Such grasses can be identified because the edges of the grass blades have an abrasive "saw blade" like feeling when touched.

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.
A blade of grass?
Do you mean a Blade of grass.
