Detailed explanation-1: -The globule is the male reproductive part and the nucule is the female reproductive part. The nucule or the oogonium lies above the globule or antheridium. Chara is a monoecious plant so it contains both male and female parts on a single plant. Hence, the right answer is option C.
Detailed explanation-2: -Sexual Reproduction in Chara The male sex organ is spherical and yellow to red in colour, called globule. The female sex organ is oval and greenish in colour and called the nucule or oogonium. The sex organs are borne on the branch of limited growth mingled with secondary laterals.
Detailed explanation-3: -All species of chara reproduce sexually and show highly advanced oogamy. Male and female gametangia are called antheridia and oogonia respectively. Male fructification is called globule and the female is nucule.
Detailed explanation-4: -Nucule is the female sex organ and globule is the male sex organ in Chara. It is a freshwater green alga found attached to bottoms of shallow water of ponds, pools and lakes. It is commonly called aquatic horse tail because of jointed appearance.
