Does life begin with cells? • Grow • Reproduce • Process information • Respond to stimuli • Carry out chemical reactions " Now let man but think from what he is created " (56: 5) " We created you out of dust, then out of a sperm, then We fashioned you into something which clings into a chewed lump of flesh, partly formed and partly unformed" (22: 5)

Shapes of cells

Different types of cells make up each organ in the body. The types of cells making up an organ determine the organ’s function. The different types of cells that develop from the zygote to form adult human body organs

Origin of Cells

Prokaryotes and Eukaryotes
