Question

Consider this animal cell.

The organelles in an animal cell are labeled. Part D are stacked tubular structures.

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; found in animal cells but not plant cells
mitochondria; the only energy-generating structures found in cells

Answer 1

centrioles; they are found in animal cells but generally absent from plant cells (they're short cylindrical bundles of microtubules involved in cell division).
