Difference between plant and animal cell

Click For Summary

Discussion Overview

The discussion centers on the differences between plant and animal cells, exploring various characteristics such as size, shape, organelles, and structural components. It includes comparisons of their features and implications for survival and adaptation.

Discussion Character

  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants note that plant cells are generally larger than animal cells and cannot change shape, while animal cells can change shape.
  • It is mentioned that mature plant cells contain a large central vacuole, whereas animal cells typically have many small vacuoles.
  • Some participants highlight the presence of plastids in plant cells, particularly chloroplasts, which are usually absent in animal cells.
  • There is a claim that lysosomes are rare in plant cells but always present in animal cells.
  • Glyoxysomes may be present in plant cells, while they are absent in animal cells.
  • One participant emphasizes that a common distinction is that plant cells have cell walls, while animal cells do not.
  • Another participant describes the rigidity of cell walls in plants compared to the more flexible nature of animal cells, likening plants to straws and animals to bags.
  • There is a suggestion that for smaller organisms, a plant-like structure may enhance survival and propagation, while larger organisms may benefit from an exoskeleton.

Areas of Agreement / Disagreement

Participants express various viewpoints regarding the differences between plant and animal cells, with no clear consensus on all points raised. Some distinctions are widely acknowledged, while others remain contested or elaborated upon differently.

Contextual Notes

Some claims depend on specific definitions of organelles and structures, and there may be limitations in the assumptions made about the characteristics of cells across different organisms.

A plant cell is usually larger in size. An animal cell is comparatively smaller in size. 2. It cannot change its shape. An animal cell can often change its shape. 3. A mature plant cell contains a large central vacuole. An animal cell often possesses many small vacuoles. 4. Plastids are present. Plant cells exposed to sunlight contain chloroplast. Plastids are usually absent in Animal cells. 5. Lysosomesare rare in Plant cell. Lysosomes are always present in animal cells. 6. Glyoxysomes may be present in Plant cell. They are absent in Animal cell.
Is it right?

Most elementary distinctions between plant and animal cells mention that plant cellls have cell walls and animal cells do not.
 
Cell walls are rigid - think wood. Animals are more like bags, plants are more like straws - on a microscopic scale. Or an imaginative scale anyway.
Plants have cell walls, animals cells have a cell membrane only. Animals like coral can build structures out of hard stuff like calcium carbonate to protect their squishy parts from predators. Crabs have an exoskeleton to protect the squishy parts, humans have skin and a structure to park the squishy parts inside - connective tissues and the skeleton.
 
This sort of thing get me thinking.
For smallish organisms a plant-like structure seems to have much better chances of survival and propagating.
For larger scale organisms an exoskeleton is better. ( on Earth anyway)
