Practice DAT (Dental) Cell Biology in the app →A biologist sorts every cell she studies into one of two broad categories. Those categories are eukaryotic andA student lists what every prokaryote has: chromosomal DNA in a nucleoid, ribosomes, a cell membrane and a:The structures responsible for building proteins in any cell are the:A gland cell churns out huge amounts of protein. Compared with other cells it should be especially rich in:An oval organelle with a double membrane carries its own ribosomes and DNA. That organelle is the:Inside that organelle, the process consumes oxygen and gives off one waste gas. That gas is:Cellular respiration makes the molecule that stores energy for short-term use. That molecule is:A plant cell organelle carries out photosynthesis. That organelle is the:A student lists what plant cells have and animal cells lack: a cell wall, plastids and a large:Ribosomes stud one part of the endoplasmic reticulum, giving it a bumpy look. That part is the:The other stretch of that network runs on with few or no ribosomes on its surface. It is the:In animal cells, one organelle digests waste and recycles worn-out organelles. It is the:In plant cells, those digestive processes happen instead inside the:Small, round organelles enclosed by a single membrane, unlike mitochondria, are the:Membrane-bound sacs that store material and move it about the cell are vacuoles and:Inside the nucleus, a condensed region of chromatin is where ribosomes get built. That region is the:The membrane around the nucleus runs continuously into another organelle. That organelle is the:The cytoskeleton is built from three kinds of fibre: microtubules, microfilaments and:The fibres that hold organelles in position throughout the cell are the:Flagella, cilia and centrioles are all built from the same structural element. That element is:Junctions that act like spot welds holding neighbouring epithelial cells together are:A cell that grows too large runs into trouble because its volume grows faster than its:
