Consider the following statements.
I. Kingdom Plantae includes eukaryotic, autotrophic, chlorophyll containing organisms.
II. It includes algae bryophytes, pteridophytes, gymnosperms, but not angiosperms.
III. Plants show alternation of generation [between haploid gametophytic (n) phase and diploid sporophytic (2n) phase].
Which of the statement given above are correct?

Options

A. I and II
B. I and III
C. II and III
D. All of these

Answer

To determine which statements about Kingdom Plantae are correct, let's analyze each statement step by step.

### Step-by-Step Solution:

1. **Statement I: Kingdom Plantae includes eukaryotic, autotrophic, chlorophyll-containing organisms.**
- **Analysis:** This statement is correct. Kingdom Plantae consists of eukaryotic organisms that can perform photosynthesis due to the presence of chlorophyll, making them autotrophic. They are capable of producing their own food using sunlight.

2. **Statement II: It includes algae, bryophytes, pteridophytes, gymnosperms, but not angiosperms.**
- **Analysis:** This statement is incorrect. While the statement correctly lists algae, bryophytes, pteridophytes, and gymnosperms as members of Kingdom Plantae, it incorrectly states that angiosperms are not included. Angiosperms, or flowering plants, are indeed a significant part of the plant kingdom.

3. **Statement III: Plants show alternation of generation (between haploid gametophytic (n) phase and diploid sporophytic (2n) phase).**
- **Analysis:** This statement is correct. In the life cycle of plants, there is an alternation of generations where the gametophyte (haploid) phase alternates with the sporophyte (diploid) phase. This is a fundamental characteristic of the plant kingdom.

### Conclusion:
- **Correct Statements:** I and III are correct.
- **Incorrect Statement:** II is incorrect.

Thus, the correct option is that statements I and III are correct, while statement II is incorrect.

### Final Answer:
The correct statements are I and III.
