Scientists collected four organisms during an excursion to the Great Lakes. When they got back to their laboratory, they discovered that the specimen samples got mixed up. When reading through their scientific journal, they knew the following things about each sample. - Specimen W is multicellular. - Specimen X is smaller than all the other specimens. - Specimen Y uses cilia on its outer edge to move. - Specimen Z is a bacterial cell. Which picture below would best represent Specimen W?

The process of division of labor is different cells performing specific jobs in a multicellular organism. Please select the specific job of the specialized cell shown below.

• The main function is the responsibility for practically all voluntary movements.

• The main function is to conduct photosynthesis which creates sugars from sunlight.

• The main function is to receive and send messages from the body to the brain.

• The main function is to carry oxygen from the lungs and deliver it throughout the body.

The function of chloroplasts in a plant cell is to complete…

• transport of proteins throughout the cell

• cellular respiration and the production of energy

• allow materials to enter and exit the cell
