The picture shows the cell structure pattern of an organism. According to the picture, the answer is: (1) cells are _ _ _ _ biological cells, and the reason is _ _ _ _. (2) the cells are fine.
(1) The cell has no nucleus surrounded by nuclear membrane and belongs to prokaryotic cell.

(2) Compared with animal cells, this cell has ribosomes, 5 cytoplasm and 7 cell membranes.

(3) Most prokaryotes belong to heterotrophs.

(4) Organisms belong to prokaryotes, and their genetic material exists in pseudonuclei in the form of rings (3), while the genetic material of eukaryotes mainly exists in the form of chromosomes.

So the answer is:

(1) Prokaryotes? A nucleus without a nuclear membrane.

(2)[ 1] ribosome, [5] cytoplasm and [7] cell membrane

(3) Heterotrophication

(4)③ Quasi-nucleus? Ring chromosome
