T2L3 Obtaining and Removing Materials

An amoeba is a single-celled organism. Amoebas extend their cell membrane around a food particle or prey organism. Then, they bring the food into the cell, as is shown in the illustration. Which term best describes the cell process amoebas use to get food?

• exocytosis

• endocytosis

• passive transport

• facilitated diffusion

Talitha is performing an experiment on how plants get water up to their leaves. She adds two drops of blue food coloring to a beaker of water. Then, she hears a fire alarm and heads outside. When Talitha gets back to the classroom, the water in the beaker is all pale blue. She recognizes that the process of ___________________________ has caused the dye to spread evenly through the water.
