Q.Which of the following statements is incorrect?

The wrong statement is that antheridia occur on the antheridiophore of the FEMALE thallus of Marchantia.

Let us check each statement:

• (a) Marchantia is dioecious; male and female sex organs are borne on separate thalli on special stalked structures. Antheridia (male) are borne on the antheridiophore of the MALE thallus, while archegonia (female) are on the archegoniophore of the female thallus. So saying antheridia are on the antheridiophore of the FEMALE thallus is incorrect.
• (b) Chara is monoecious (bears both sex organs) — correct. …

Isogametes are found in the alga Cladophora.

Isogametes are gametes that are similar in size and structure so that the fusing gametes cannot be labelled as male or female (isogamy). This condition is seen in many algae such as Cladophora. The frog and birds show anisogamy/oogamy with clearly different …

The bryophyte plant body is haploid (gametophyte).

In the life cycle of plants there is an alternation of a haploid gametophyte and a diploid sporophyte. In bryophytes (mosses, liverworts) the dominant, green, independent plant body is the haploid gametophyte, on which a dependent diploid sporophyte grows. In pteridophytes, gymnosperms …

Earthworm is hermaphrodite — a single individual has both male and female reproductive organs.

A hermaphrodite (bisexual) organism possesses both male and female reproductive organs in the same body. The earthworm bears both testes and ovaries and is a classic example of a hermaphrodite animal (although it undergoes …
