B1 Cell biology Flashcards
what does the nucleus do
controls the activities of the cell and contains the genetic material
what does the cytoplasm do
where most chemical reactions take place
what does the cell membrane do
controls passage of substances into and out of the cell
what does the mitochondia do
where aerobic respiration takes place
what do ribosomes

filled with cell sap which supports the cell
what does chloroplast do
absorb light to make glucose via photosynthesis
what is a eukaryotic cell
a cell with a nucleus
what is a prokarytic cell
a cell without a nucleus
name 3 features of prokaryotic cells
-the genetic material is not enclosed in a nucleus
-the genetic material is a single DNA loop and there may be one or more small rings if DNA called plasmids
-they do not contain mitochondria or chloroplasts
what is a flagella
tail like structure that rotate to help some bacteria move
