Question

Which organelles are labeled D, and what is one feature that distinguishes them from the other labeled organelles? chloroplasts; the only organelles that produce sugars from sunlight ribosomes; only found in animal and bacterial cells centrioles; only found in animal cells mitochondria; the only energy-generating structures found in cells

Answer 1

The correct answer is: centrioles; only found in animal cells.

Answer 2

The correct answer is: centrioles; only found in animal cells.

The centrioles are cylindrical cellular organelles which are composed of a protein- tubulin and they make up a structure called a centrosome (reulator of cell cycle). Centrioles are found in almost all eukaryotic cells, (for example, in animal cells and in the male gametes of some plants), but absent from flowering plants and most fungi.
