Question

Match and find the correct combination.

	$I$		$II$
$\left(a\right)$	Gracilaria	$\left(i\right)$	Biflagellate spores
$\left(b\right)$	Ectocarpus	$\left(ii\right)$	Elaters
$\left(c\right)$	Marchantia	$\left(iii\right)$	Biflagellate antherozoids
$\left(d\right)$	Cycas	$\left(iv\right)$	Carpogonium
		$\left(v\right)$	Multiciliated male gametes

• A. $\left(a\right)-\left(i\right),\left(b\right)-\left(iv\right),\left(c\right)-\left(iii\right),\left(d\right)-\left(v\right)$
• B. $\left(a\right)-\left(iv\right),\left(b\right)-\left(i\right),\left(c\right)-\left(ii\right),\left(d\right)-\left(v\right)$
• C. $\left(a\right)-\left(iv\right),\left(b\right)-\left(ii\right),\left(c\right)-\left(iii\right),\left(d\right)-\left(i\right)$
• D. $\left(a\right)-\left(iv\right),\left(b\right)-\left(v\right),\left(c\right)-\left(ii\right),\left(d\right)-\left(i\right)$

Answer 1

Answer: (B)

$\left(a\right)-\left(iv\right),\left(b\right)-\left(i\right),\left(c\right)-\left(ii\right),\left(d\right)-\left(v\right)$

a) Carpogonium is the reproductive structure in Gracilaria

b) The spores in Ectocarpus are biflagellate, one whiplash type and the other tinsel type

c) The sporophyte of Marchantia contain sterile spiral structures called the elaters that help in dispersal of spores

d) The male gametes of Cycas are top shaped and have bands of cilia

So, the correct answer is 'a)−(iv),(b)−(i),(c)−(ii),(d)−(v)'
