Which of these plants is correctly matched with its reproductive characteristics ?
(i) Sphagnum : Male sex organ called antheridium produce biflagellate antherozoids while the female sex organ called archesporium produces a single egg .
(ii) sequoia : One of the megaspores enclosed within the megasporangium develops into a multicellular female gametophyte that bears two or more archegonia or female sex organs
(iii) Wolffia : one of the male gametes fuses with the egg cell to from a zygote while the other male gamete fuses with the diploid secondary nucleus to produce the triploid primary endosperm nuclelus .
(iv) polysiphonia . Sexual reproduction is oogamous with non-motile gametes and accompanied by complex post-fertilization developments

Options

A. i and ii
B. i , ii and iv
C. ii,iii and iv
D. i ,ii, iii and iv

Answer

To determine which of the given plants is correctly matched with its reproductive characteristics, we will analyze each statement one by one.

### Step 1: Analyze Sphagnum
- **Statement:** "Sphagnum: Male sex organ called antheridium produces biflagellate antherozoids while the female sex organ called archesporium produces a single egg."
- **Analysis:**
- The male sex organ in Sphagnum is indeed called antheridium, and it produces biflagellate antherozoids (sperm).
- However, the female sex organ is called **archegonium**, not **archesporium**. The archegonium produces a single egg.
- **Conclusion:** This statement is incorrect.

### Step 2: Analyze Sequoia
- **Statement:** "Sequoia: One of the megaspores enclosed within the megasporangium develops into a multicellular female gametophyte that bears two or more archegonia or female sex organs."
- **Analysis:**
- Sequoia is a gymnosperm. In gymnosperms, one of the megaspores does develop into a female gametophyte, which is indeed multicellular and can bear multiple archegonia.
- **Conclusion:** This statement is correct.

### Step 3: Analyze Wolffia
- **Statement:** "Wolffia: One of the male gametes fuses with the egg cell to form a zygote while the other male gamete fuses with the diploid secondary nucleus to produce the triploid primary endosperm nucleus."
- **Analysis:**
- Wolffia is an angiosperm, and it undergoes double fertilization. One male gamete fuses with the egg cell to form a zygote, and the other fuses with the diploid secondary nucleus to form the triploid primary endosperm nucleus.
- **Conclusion:** This statement is correct.

### Step 4: Analyze Polysiphonia
- **Statement:** "Polysiphonia: Sexual reproduction is oogamous with non-motile gametes and accompanied by complex post-fertilization developments."
- **Analysis:**
- Polysiphonia is a red algae (Rhodophyta) and exhibits oogamous reproduction, where one gamete is motile (sperm) and the other is non-motile (egg). The statement mentions non-motile gametes, which is misleading because it implies both are non-motile. However, the overall description of oogamy is correct.
- **Conclusion:** This statement is somewhat misleading but can be considered correct in the context of the reproductive process.

### Final Conclusion
- The correct matches are:
- **Sequoia** (correct)
- **Wolffia** (correct)
- **Polysiphonia** (correct, despite the misleading wording)
- The incorrect match is **Sphagnum**.

### Answer
The plants correctly matched with their reproductive characteristics are **Sequoia, Wolffia, and Polysiphonia**.
