Answer :
To answer the question requiring us to differentiate between the characteristics of plant and animal cells based on the provided information, let's organize our observations systematically.
1. Nucleus:
- Plant Cell: The Nucleus in a plant cell is described as "Present at the edge of the cell."
- Animal Cell: The Nucleus in an animal cell is simply mentioned as "Present."
2. Chloroplast:
- Plant Cell: Chloroplasts are described as "Present."
- Animal Cell: Chloroplasts are "Absent."
3. Cetrosome:
- Plant Cell: Indicated with a dash '-'. This typically means that the plant cell does not have centrosomes or they are not a prominent feature.
- Animal Cell: Centrosomes are "Present."
4. Lysosome:
- Plant Cell: Lysosomes are "Absent."
- Animal Cell: The characteristic is left blank, which might imply that lysosomes' presence is not explicitly acknowledged, but for understanding purposes, lysosomes are known to be present in animal cells.
Let's summarize these observations in a table format as given:
[tex]\[ \begin{array}{|c|c|c|c|} \hline \text{S.No} & \text{Features} & \text{Plant cell} & \text{Animal cell} \\ \hline 1. & \text{Nucleus} & \text{Present at the edge of the cell} & \text{Present} \\ \hline 2. & \text{Chloroplast} & \text{Present} & \text{Absent} \\ \hline 3. & \text{Centrosome} & - & \text{Present} \\ \hline 4. & \text{Lysosome} & \text{Absent} & \\ \hline \end{array} \][/tex]
### Observations for Each Feature:
1. Nucleus:
- In plant cells, the nucleus is positioned at the edge due to the central vacuole pushing it towards the periphery.
- In animal cells, the nucleus is typically centrally located.
2. Chloroplast:
- Present in plant cells as they are essential for photosynthesis, converting light energy into chemical energy.
- Absent in animal cells because animals obtain their energy from consuming food rather than photosynthesis.
3. Centrosome:
- Plant cells generally do not have centrosomes. Instead, they use spindle fibers for cell division but without the defined centrosome structure found in animal cells.
- Animal cells have centrosomes which play a crucial role in organizing microtubules during cell division.
4. Lysosome:
- Absent in plant cells or not a prominent feature. Plant cells have other mechanisms for breaking down waste.
- Present in animal cells as they contain enzymes to digest various biomolecules, crucial for waste processing and cellular defense mechanisms.
In conclusion, by evaluating these characteristics, we can effectively differentiate between plant and animal cells.
