To start with, think about what algae actually are. They're not monophylletic, incidentally, but the many plants that we refer to as "algae" do have some things in common. It might also help to think about what characteristics higher plants have that algae lack. It's a very long list!
ok so we CAN say that common plants usually we find or the plants dont involve much complex preocess
Um... could you rephrase that? I don't know what you're trying to say.
ok i m, trying to say dat simple plant we mean i which complex proceses are not being carried out?
I found a definition which suggests algae are simple plants because they are photosynthetic (hence plants) but they don't have complex structures like most plants (xylem and phloem, stomata and the like).
ebaxter01 has the right idea. Simple vs. complex is more of a morphological descriptor, as far as I know. The chemical processes in simple plants may well be simpler than those in higher plants, but I don't think it's what the word "simple" is referring to here. If you look at a cross section of a flower stem, you'll see multiple different types of cells: they are organised into several distinct tissues or organs, and if you look at the cells themselves, epidermis cells, for example, are a very different shape and perform a very different function than e.g. phloem cells. Do you know what that phenomenon is called? Now contrast this with what you might expect to see in multicellular algae or algal colonies.
phenomenon ?plz tell me
I was talking about cellular differentiation, but also organ differentiation (not sure if that's the right term): higher plants have leaves, roots, stems, etc. with differing structures and functions. This sort of differentiation, with highly specialised cells/organs, is not present in simple plants.
yes yess i studeid this wat u are telling thnx :)
