📝 Question:
Draw a typical plant cell and label the following parts: (a) Cell wall, (b) Nucleus, (c) Chloroplast, (d) Vacuole. – Hindi Question / : : (a) , (b) , (c) , (d)
💡 Solution:
- Diagram Description / :
- Draw a hexagonal/polygonal shaped cell bounded by an outer thick layer and inner thin membrane.
- Draw a large central sac pushing the cytoplasm to the periphery.
- Draw a distinct round *Nucleus placed near the cell margin.
- Scatter oval double-membraned *Chloroplasts containing stack-like grana in the cytoplasm.

📝 Question:
Write a difference between cell wall and cell membrane. – Hindi Question /
💡 Solution:
Cell wall is a non-living, rigid, fully permeable outer boundary made of cellulose found only in plant cells. Cell membrane is a living, flexible, selectively permeable boundary made of proteins and lipids found in both plant and animal cells.

📝 Question:
Draw a labeled diagram of a typical animal cell. – Hindi Question /
💡 Solution:
- Diagram Description / :
- Draw an oval or irregular shape delimited by an outer *Cell Membrane.
- Draw a centrally located round *Nucleus containing chromatin threads and nucleolus.
- Surround the nucleus with Endoplasmic Reticulum and stacked Golgi Apparatus.
- Scatter rod-shaped Mitochondria and small spherical Lysosomes in the cytoplasm.

📝 Question:
How are prokaryotic cells different from eukaryotic cells? – Hindi Question / : ?
💡 Solution:
| Feature / | Prokaryotic Cell / | Eukaryotic Cell / |
|---|---|---|
| Membrane-bound Organelles | Absent (Mitochondria, Plastids, ER, Golgi absent). | Present (Mitochondria, Plastids, ER, Golgi present). |
| Ribosomes / | Smaller size (70S type). | Larger size (80S type in cytoplasm). |
| Examples / | Bacteria, Cyanobacteria. | Plant and Animal cells. |

📝 Question:
Explain how the cell theory clarifies our understanding of the cell. – Hindi Question /
💡 Solution:
Cell theory established that the cell is the fundamental structural, functional, and organizational unit of all living organisms.
- It disproved the ancient belief of spontaneous generation by establishing that all new cells arise from pre-existing cells through cell division (Omnis cellula-e-cellula).

हरितलवक
📝 Question:
Write two similarities and two differences between mitochondria and chloroplast. – Hindi Question /
💡 Solution:
| Feature | Mitochondria / | Chloroplast / |
|---|---|---|
| Occurrence / | Present in almost all eukaryotic cells (plants & animals). | Present only in photosynthetic plant cells. |
- Similarities / :
- Both are bounded by a double-layer membrane.
- Both contain their own genetic material (DNA) and ribosomes, allowing them to divide semi-autonomously.
- Differences / :
