Question

1. which sequence illustrates the increasing complexity of levels of organization in multicellular organisms? a) cell→organelle→tissue→organ→ organ system→organism b) cell→organism→organ system→organ→ tissue→organelle c) organelle→cell→tissue→organ→ organ system→organism d) organelle→tissue→cell→organ→ organ system→organism

Explanation:

In multicellular organisms, organelles are components within cells. Cells are the basic unit of life. Tissues are made up of similar cells. Organs are composed of different tissues. Organ systems are groups of organs working together. And an organism is made up of all these levels. So the correct order from least to most complex (increasing complexity) is organelle → cell → tissue → organ → organ system → organism.

Answer:

C. organelle → cell → tissue → organ → organ system → organism
