Which plant pathogen structure is delicate, threadlike filaments called hyphae
A
fungi
B
nematodes
C
algae
D
virus
Explanation: 

Detailed explanation-1: -Like plants and animals, fungi are eukaryotic multicellular organisms. Unlike these other groups, however, fungi are composed of filaments called hyphae; their cells are long and thread-like and connected end-to-end, as you can see in the picture below.

Detailed explanation-2: -Most multicellular fungal bodies, commonly called molds, are made up of filaments called hyphae. Hyphae can form a tangled network called a mycelium and form the thallus (body) of fleshy fungi.

Detailed explanation-3: -Hyphae are the structures that allow fungi to grow and feed, and they can also form specialized structures necessary for the fungus to survive or capture prey. The mushrooms we are used to seeing have hyphae that grow under the ground in large, intricate networks of filaments, called the mycelium.

Detailed explanation-4: -Structure. A hypha consists of one or more cells surrounded by a tubular cell wall. In most fungi, hyphae are divided into cells by internal cross-walls called “septa” (singular septum). Septa are usually perforated by pores large enough for ribosomes, mitochondria, and sometimes nuclei to flow between cells.

Detailed explanation-5: -In addition, fungal “hyphae, ” which are long, thread-like structures, resemble the roots of plants.
