Biology CH.7 Flashcards

Here is biology chater 7 for Prentice Hall Biology book (CP bio) Have fun learning all about cells and everything having to do with them!!!!

13492995mitochondrianconverts the chemical energy stored in food into compounds that are more convenient for the cell to use17
13492996chloroplastcaptures the energy from sunlight and converts it into chemical energy18
13492997cytoskeletonmaintain cell shape and cell movement19
