Question

3a. List two characters/traits shared by ALL plants that are NOT shared by ANY animals 3a. Consider the traits you listed in the previous question. Would any of them help you to distinguish a plant (e.g., a pine tree) from an animal (e.g., you)? Choose one: YES NO (highlight in color and bold) 3b. Consider the same plant traits. Would any of them, by themselves, help you to distinguish one species of plant from another species of plant? Choose one: YES NO (highlight in color and bold) If you chose yes” for 3a and "no” for 3b, then you successfully used synapomorphies unique to plants to distinguish them from animals. The same traits, because all plants have them, cannot be used to distinguish among plant species Remember that “primitive" and “derived" are relative/comparative terms With respect to animals, the plant traits you listed are synapomorphies. . Plants have them; animals don't. The traits are thus derived with respect to animals . With respect to all plants, however, the plant traits are symplesiomorphies, . All plants have them, so they are primitive to all plants As you can see, it works both ways

Explanation / Answer

two characteristics which are shared by all plant but not shared by any animal are

1. Plant synthesized all amino acid, vitamin and coenzyme required for their development, animals lack this characteristic.

2. plant cells have cell wall, therefore, placing them in hypotonic solution will not result in cell burst, whereas animal cells lack cell wall

3a) yes, these characteristics can help to distinguish between animal and plant cells

3b) no, As all plant inherited these characteristics, therefore cannot be used to distinguish between the plant of different species.
