The most important concern of grape farmers who engage in this practice should be that the _____.

The following statements describe something about the body structures or functions of fungi
|
Some fungi secrete digestive enzymes into the environment and then absorb the digested nutrients.
Some fungi can grow as either filamentous or single-celled forms. All fungi are heterotrophs; some species live as decomposers and others as symbionts Mycelia are made up of small-diameter hyphae that form an interwoven mass, providing more surface area for nutrient absorption. |
|
Fungal mycelia _____
|
Have a large surface area composed of branching hyphae

|
Why is it more difficult to treat fungal infections than bacterial infections in humans?
|
Fungal and animal cells and proteins are similar. Thus, drugs that disrupt fungal cell or protein function may also disrupt human cell or protein function.
