Root hairs are thin outgrowths from certain plant roots that enhance water and nutrient absorption from the soil. Which of the following best describes how root hairs are specialized for this function?

A. Root hairs are specialized for the phagocytosis of nutrients and water in the soil.

B. Root hairs contain an increased number of vacuoles that store water for the plant.

C. Root hairs have an elongated shape that increases the surface area-to-volume ratio.

D. Root hairs have specialized membranes that have increased permeability to water and nutrients.

How is the male reproductive system different from other body systems? it isn’t necessary to vital signs. it monitors other body systems, and adjusts if necessary. it transports items from one system to another. it is the only system that produces hormones in the male.

With the description of the different cell walls, membranes, and associated proteins set in the students' minds, you now need to introduce them to the idea that the cell wall can also act as a foundation to build things upon. bacterial appendages require a strong foundation that will offer the support needed to move and function in a dynamic world. for example, flagella are long, whiplike protein structures that are used by many gram-positive and gram-negative bacteria for locomotion. in order to function effectively, a flagellum must be firmly anchored to the cell wall. how will you be able to get across the idea that the peptidoglycan cell wall is strong enough to support such a mechanism? with a protein rod that passes through the cell wall and protein rings used to anchor it in the membranes, these basal bodies are the rudimentary biological motors that use atp power to spin the hook and the flagella attached to it. bacterial flagella have a biological motor that spins within the cell wall and is powered by atp. this allows the flagella to spin in a whiplike motion to propel the bacterium.
