Leaves of moss plant posses

Options

A. Stomata and chloroplasts
B. No stomata, no chloroplasts
C. Stomata but no chloroplasts
D. No stomata but chloroplasts.

Answer

### Step-by-Step Text Solution:

1. **Identify the Plant Group**: The leaves of moss plants belong to the group called Bryophyta, which is a division of non-vascular plants.

**Hint**: Remember that mosses are part of a larger group of plants known as bryophytes.

2. **Structure of the Plant Body**: Moss plants generally have a thalloid type of plant body, meaning they do not have true leaves, stems, or roots like higher plants.

**Hint**: Think about how mosses differ from flowering plants in their structure.

3. **Leaf Characteristics**: The leaves of moss plants are not well-developed and are usually small and simple in structure.

**Hint**: Consider the size and complexity of moss leaves compared to those of vascular plants.

4. **Presence of Pores**: Moss leaves have tiny pores but lack true stomata. This means gas exchange occurs through these pores.

**Hint**: Recall the function of stomata in other plants and how mosses adapt to their environment.

5. **Chlorophyll and Photosynthesis**: Mosses are autotrophic, meaning they can produce their own food through photosynthesis. They contain chlorophyll, which is essential for this process.

**Hint**: Think about how chlorophyll contributes to the green color of plants and their ability to perform photosynthesis.

6. **Absence of Stomata**: While moss leaves do not have stomata, they do contain chloroplasts, which are the sites of photosynthesis.

**Hint**: Reflect on the importance of chloroplasts in plant cells and how they relate to the plant's ability to photosynthesize.

### Summary:
Leaves of moss plants possess characteristics such as being part of the Bryophyta group, having a thalloid structure, being small and simple, containing tiny pores for gas exchange, and having chlorophyll for photosynthesis, despite the absence of true stomata.
