Read the following statements.
(a) Volvox does not have a free living sporophyte.
(b) All alga show haplontic life cycle.
(c) Sporophyte of Fucus is dominant and photosynthetic.
(d) All seed bearing plants have diplontic life cycle
(e) Bryophytes have haplodiplontic life cycle
Select the option with correct set of statements.

Options

A. (a), (b), (c) ,(d),(e)
B. all except (d)
C. all except (c)
D. all except (b)

Answer

To solve the question, we need to evaluate each statement regarding their correctness. Let's analyze each statement step by step.

### Step 1: Analyze Statement (a)
**Statement (a):** "Volvox does not have a free living sporophyte."
- **Analysis:** Volvox is a genus of green algae that primarily exists in a colonial form. In Volvox, the sporophyte is dependent on the gametophyte for its nutrition and does not have an independent existence. Therefore, this statement is **correct**.

### Step 2: Analyze Statement (b)
**Statement (b):** "All algae show haplontic life cycle."
- **Analysis:** While many algae do exhibit a haplontic life cycle (where the dominant stage is haploid), there are exceptions. Some algae, such as certain red and green algae, can have a haplodiplontic life cycle. Thus, this statement is **incorrect**.

### Step 3: Analyze Statement (c)
**Statement (c):** "Sporophyte of Fucus is dominant and photosynthetic."
- **Analysis:** Fucus is a brown alga where the sporophyte is indeed the dominant phase of the life cycle and is photosynthetic. Therefore, this statement is **correct**.

### Step 4: Analyze Statement (d)
**Statement (d):** "All seed-bearing plants have diplontic life cycle."
- **Analysis:** Seed-bearing plants, which include gymnosperms and angiosperms, typically have a diplontic life cycle where the diploid sporophyte is the dominant phase. Therefore, this statement is **correct**.

### Step 5: Analyze Statement (e)
**Statement (e):** "Bryophytes have haplodiplontic life cycle."
- **Analysis:** Bryophytes, which include mosses and liverworts, do indeed have a haplodiplontic life cycle, where both haploid (gametophyte) and diploid (sporophyte) stages are present. Therefore, this statement is **correct**.

### Summary of Statements:
- (a) Correct
- (b) Incorrect
- (c) Correct
- (d) Correct
- (e) Correct

### Conclusion:
The only incorrect statement is (b). Therefore, the correct option is "All except (b)".

### Final Answer:
The correct set of statements is: All except (b).
