A plasma cell is a type of B lymphocyte (white blood cell) that has differentiated and specialized to synthesize huge numbers of antibodies very quickly. The specific protein structure of the antibodies enables them to bind to and neutralize antigens that resulted in their production. Given their role, you might expect plasma cells to contain especially large amounts of ______. Copyright 2024 by Edmonds College Department of Biology. All rights reserved.

A white blood cell of your immune system uses phagocytosis to capture and engulf a bacterial pathogen. Once inside the cell, the vesicle (called a phagosome) containing the bacterium is fused with a ______, an organelle that contains digestive enzymes that help break apart the pathogen.

Mitochondria contain their own DNA and ribosomes for protein synthesis of a number of proteins they require. However, a larger number of proteins are actually coded for in the nucleus of the cell, are synthesized in the cytoplasm, and are then transported to mitochondria. Based on what you know about protein transport processes, how do you think these proteins most likely make their way to mitochondria? Copyright 2024 by Edmonds College Department of Biology.

Researchers took two different species of sponge (a type of simple aquatic animal), treated them to disassociate their cells, mixed the cells, and then observed as the cells slowly reaggregated by cell type and species.
