---
**Diagrams and Explanations:**
**1. Protonema with young plant and buds (A)**
- Protonema: Early stage in the lifecycle of moss, where filamentous structures develop.
- Young plant and buds: Emerging from the protonema indicating initial stages of moss growth.
- *Labeled parts*: Male gametophyte.
**2. Archegonial tip (B)**
- Archegonialaip: Structure at the tip of the female reproductive organ in mosses.
- *Labeled parts*: Female gametophyte
**3. Antheridial tip (C)**
- Antheridial tip: Part of the structure containing male reproductive organs.
- *Labeled parts*: Male gametophyte
**4. Archegonium with egg (D)**
- Archegonium: Female reproductive organ in mosses.
- Egg within archegonium: Site of fertilization.
- *Labeled parts*: Neck, venter
**5. Antheridium (E)**
- Antheridium: Male reproductive organ in mosses producing sperm cells.
**6. Leafy shoot with sporophyte (F)**
- Leafy shoot: The green vegetative part of moss representing the gametophyte.
- Sporophyte: Generation that produces spores, usually seen attached to the gametophyte.
- *Labeled parts*: Capsule (sporangium), seta, neck, rhizoids.
**7. Sporophyte (capsule) parts (G)**
- Detailed structure of the capsule where spores are generated.
**8. Section of capsule (H)**
- Cross-section showing the internal structure of the capsule.
These illustrations and descriptions provide an insight into the reproductive structures and lifecycle of moss. Understanding these components is crucial in studying bryophyte biology and ecology.

**C. Antheridium**
- **Structure of antheridium**: Detailed breakdown showing the internal organization of the male reproductive unit.
**D. Archegonial Thallus with Cupules**
- Similar structure to the Antheridial Thallus but features the Archegonial Receptacle.
- **Female Gametophyte**: The female reproductive organ.
**E. Archegonial Receptacle with Archegonia**
- **Archegonia**: Female reproductive organs producing eggs.
- **Archegonial Receptacle**: Enlarged structure holding the archegonia.
**F. Archegonium with Egg and Ventral Canal Cell**
- Detailed view showing the egg cell and the ventral canal cell within an archegonium.
**G. Sporophyte**
- **Sporophyte**: The diploid generation producing spores.
- **Gametophytic Tissue**: Tissue that surrounds and nourishes the developing sporophyte.
- **Spores Mixed with Elaters**: Structure for spore dispersal.
**H. Thallus Section Showing Structure**
- **Sectional View**: Provides a cross-sectional view of the thallus.
- **Internal Structure**: Shows the inner cellular organization of the thallus, including photosynthetic cells and supportive tissues.
This detailed worksheet aids in understanding the structural and reproductive biology of **Marchantia**, a type of **liverwort**, showcasing
