complexity?
(1) tissues → cells → organelles → organs
(2) cells → organelles → organs → organism

Sagot :

The question is asking us to choose the order of increasing complexity and the correct answer is (3) organelles → cells → tissues → organs. Organelles are parts of cells, for example a mitochondrium is an organelle. Many cells form tissues and tissues form an organ. Many organ for an organism, for example, a human being is an organism - that's the whole animal or plant.
