Vedclass · Answer

(B) $1$. Zoospores are motile,unicellular asexual reproductive structures that possess flagella and lack a rigid cell wall.$2$. Conidia are non-motile,unicellular asexual reproductive structures that lack flagella and possess a cell wall.$3$. Gametes are unicellular haploid cells that may or may not possess flagella (e.g.,isogametes in Chlamydomonas are flagellated) and may or may not have a protective wall.$4$. Comparing the table provided in the question with biological facts: Row $(b)$ (Conidia) is correctly described as unicellular,flagella absent,and wall present. Row $(c)$ (Gamete) is correctly described as unicellular,flagella can be present,and wall can be present. Row $(a)$ is incorrect because zoospores lack a cell wall.$5$. Therefore,$(b)$ and $(c)$ are the correct descriptions.

Structure	Cellular structure	Flagella	Wall
$(a)$ Zoospore	Unicellular	Present	Absent
$(b)$ Conidia	Unicellular	Absent	Present
$(c)$ Gamete	Unicellular	Can be present	Can be present
