Peas, beans, and peanuts are all examples of legumes. legumes are a specific type of plant which possess nodules on their roots, as shown below. what is the purpose of these nodules? a. the nodules store plant sugars which are created during the process of photosynthesis. b. the nodules contain pumps which allow water to enter the roots using reverse osmosis. c. the nodules contain chemicals which repel insects, like ants and beetles. d. the nodules contain bacteria which can convert atmospheric nitrogen into ammonia.

The purpose of these nodules is that they contain bacteria whcih has the ability to convert atmospheric nitrogen into ammonia.

Explanation:

A small buldged like part present in the roots of leguminous plant due to symbiosis association of root with the nitrogen fixing bacteria such as rhizobium is called as root nodules.

It is composed of protein and nitrogen fixing bacteria. Under nitrogen deficient condition, the legemunous plant with help of root nodules traps the atmospheric nitrogen and fixes it with the help of nitrogen fixing bacteria present in them.

well we can't tell you because we cant see the time give a screen shot or something.

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
