I wonder over the distinction "animal tissue" and "plant tissue". Does "animal" here actually mean mammal, or do all animals including insects etc. have these four types of tissues? / Habj 00:52, 26 October 2005 (UTC)
- Generally speaking, yes. -Dcfleck 23:59, 27 October 2005 (UTC)

- In general, all kinds of animals have these four basic types of tissue, including animals as simple as jellyfish and corals. And these kinds of tissues are different in plants, where tissues evolved independently from unicellular ancestors. -- EncycloPetey 04:44, 29 October 2005 (UTC)
Why aren't parenchyma/secretory tissues mentioned?
- Parenchyma is generalized (unspecialized) tissue. In both animals and plants, it can occur in a wide array of more specific tissue types. In plants, for example, parenchyma occurs in the xylem, in the phloem, in the epidermis, in the cortex. The way this article is currently structured, it covers the major tissue types, and not all of the specific subtypes. If you're amenable to the idea (and have the requisite knowledge), I'd say that you should expand the parenchyma article. If that article were a full and proper length, it probably would be more prominently featured.
[edit] types of animal tissue
A picky point perhaps. The text says there are four basic types of tissue in the body of all animals, but 5 are listed: Epithelium, Connective tissue, Muscle tissue, Nervous tissue, and Areolar connective tissue. Am I forgetting something?
