Are there any intermediates in plants, and by that I mean any cell walls

To say that 'bones are made of calcium and plant cell walls are made of
carbon' is an utterly ridiculous oversimplification. Bone is composed of
a melange of several different calcium minerals, and is also about 1/3
protein. Plant cell walls are (generally) composed of pectin, pectic
acid, various glucose polymers and proteins. Pectic acid is formed from
pectin molecules glued together with calcium and magnesium ions. Bone
and plant cell walls are not analogously derived structures, and there
is no inherent dichotomy to be found.

ANd there are plants (well, algae, or are they still algae?) like Chara
that have an external calcium compound coating. And most phyla of animals
have either no skeleton or a skeleton made of chitin, another organic
polymer. Even many vertebrates lack calcified bones.

Chloroplasts. The inverse or reverse in animals (the compliment) would
be some organs or system of animals that makes or allows animals/bacteria
to move around. Plants are stationary for the most part. In bacteria that
are
able to move around such as the flagella. Then the inverse or reverse or
Compliment of chloroplasts is the flagella for certain type of bacteria and
those
bacteria would then be members of the animal kingdom.

Some plants have motile sperm, with a flagella. Plants therefore have
both chloroplasts and their (your) "antipode", flagella. Your reasoning
about bacteria being animals because they move is about 200 years outdated.

Don't get him started on sperm or he'll go into his penis routine. He
concluded from the pili of bacteria that the penis is the most important
organ, ignoring that fact that most animals, including most vertebrates,
don't have intromittent organs, yet do just fine for themselves
reproductively. Plants seem to do fine without them too.

Perhaps you should try less writing and more reading.

Don't get your hopes up.
