Analogous means that the structures have different origins, but they do the same things. Homologous means the opposite: that they have the same origins but are adapted to do different functions.
1. HOMOLOGOUS ( morphological and anatomical evidences ) .These are the organs that have same basic structural plan and origin but different functions. 2. ANALOGOUS These are the organs that have different origin and structure plan but same function
Tendrils of a plant and phylloclades of Opuntia are analogous structures. They serve similar functions (support and water storage) but have different origins. Tendrils are modified leaves or stems, while phylloclades are modified branches.
Homoplasy refers to similarities in traits between different species that are not inherited from a common ancestor, while homologous structures are traits that are inherited from a common ancestor and have similar functions.

In biology, an analogous character is a trait that appears similar in different species but is not inherited from a common ancestor. This concept is important in understanding evolutionary relationships. Character homology, on the other hand, refers to traits that are inherited from a common ancestor. By distinguishing between analogous and homologous characters, scientists can better understand the evolutionary history of different species.

Homologous = same origin, different function (arms vs. wings) Analogous = same function, different origin (panda thumb)
analogous
Analogous!
Homologous organs have similar embryonic origin and basic structure whereas Analogous organs have different embryonic origin and basic structure. Homologous organs may look different and may perform different function; e.g., forelimb of a man and flipper of a whale. Whereas Analogous organs look alike and perform same functions; e.g., Wings of birds and insects.
They are both. They are homologous because they are both examples of a vertebrate forelimb. They are analogous because they were adapted for flight independently of one another.
Homologous organs have similar looking structure and similar origin but different functions . Whereas analogous is just the opposite analogous organs are those that have similar function but different origin and structure
describe a chemical test you would use to show the difference between an isomer and a homologous series
Structures
In biology, homologous structures are defined as structures which serve the same purposes because they evolved from the same source (divergent evolution), the opposite of analogous structures, which serve the same purpose but evolved through convergent evolution. Birds' wings and bats' wings are both homologous and analogous. As wings, the two are analogous, but as forelimbs, the two are homologous.
