Answer:
80%
Explanation:
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. Seeds can only be produced when pollen is transferred between flowers of the same species.
Honeybees pollinate 80 percent of U.S grown crops—products valued at more than $14 billion. Crops that benefit from honeybee pollination include fruits, nuts, vegetables, cotton and other small grains. They also include cover crops, which farmers plant between commercial crops to prevent nutrient runoff and soil erosion and boost soil nutrients.
It’s estimated that there are about 2.4 million honeybee colonies in the U.S. today.
In a single day, one honeybee makes 12 or more trips from its hive, visiting several thousand flowers at a time. On each trip, it confines its visit to one plant species, collecting one kind of pollen. This enables the colony to find and collect food with maximum efficiency, which makes honeybees the most valuable pollinators.
Answer:
The definition of an organism is a creature such as a plant, animal or a single-celled life form, or something that has interdependent parts and that is being compared to a living creature.

Explanation:
For young students things are 'living' if they move or grow; for example, the sun, wind, clouds and lightning are considered living because they change and move. Others think plants and certain animals are non-living.You need a microscope to see them. They are called microorganisms. Organisms can be made up of just one cell. They are called unicellular organisms or single celled organisms. Examples include bacteria, and protozoa such as the Amoeba and Paramecium.

Answer
Cellulose, lignin and suberin are the chemicals that provide rigidity to cell wall.
Explanation
In plant two type of growth occurs, primary and secondary growth. in primary growth when new cells are formed they are bounded by primary wall whose composition in mainly of cellulose. in secondary growth accumulation of lignin in secondary wall, suberin in cork cell wall and lignin in xylem cell wall occurs which provide rigidity.
