Which of the following is an example of non-embryophyta?

Options

A. Ephedra
B. Pteridium
C. Riccia
D. Ulothrix

Explanation

To determine which of the following is an example of non-embryophyta, we need to follow these steps:

### Step 1: Understand Non-Embryophyta
Non-embryophyta refers to plants that do not have vascular tissues. These plants are often referred to as non-vascular plants. Vascular tissues are specialized cells that transport water and nutrients throughout the plant.

### Step 2: Identify Characteristics
Non-embryophyta plants typically include groups such as mosses, liverworts, and hornworts. They lack the vascular system, which means they cannot efficiently transport water and nutrients from the soil.

### Step 3: Analyze the Options
We need to evaluate the options provided in the question to identify which one represents a non-embryophyte:
- **Option A**: (Not provided in the transcript)
- **Option B**: (Not provided in the transcript)
- **Option C**: (Not provided in the transcript)
- **Option D**: Lothric (a filamentous green algae)

### Step 4: Determine the Correct Answer
Among the options, Lothric is identified as a filamentous green algae that is found in freshwater and marine environments. It is important to note that Lothric, being an algae, does not possess vascular tissues, thus categorizing it as a non-embryophyte.

### Conclusion
The correct answer to the question "Which of the following is an example of non-embryophyta?" is **Option D: Lothric**.
