CELLS UNIT

Cell = the smallest unit that can carry on all the processes of life

Page 3: CELL SB 1 a Explain the role of cell organelles for both prokaryotic and eukaryotic cells, including the cell membrane, in maintaining homeostasis and

CELL DIVERSITY- cells are limited in size by their surface area to volume ratio- at some point, a cell can’t take in enough energy quickly enough to live

- organelles = cell components that perform specific functions for the cell

- two types: eukaryotes and prokaryotes
