The Cell Cycle
u u

What ucontrols uthe ulife uand udevelopment uof ua
ucell?

Why?
An u old u piece u of u poetry usays u“to ueverything u there uis u a u season... u a u time u to ube u born, ua u time u to udie.”
u For u cells, uthe u line u might u say u “a u time u to u divide u and u a u time u to u grow.” u In u multicellular u organisms,
u different u types u of ucells uhave u different u roles u and uneed u to ucomplete u specific u tasks. u For uexample, u a
u cell uthat u isn’t u large u enough u is unot uuseful ufor ustoring unutrients ufor ulater, ubut ua ucell uthat uis utoo
ularge uwill unot ube uuseful ufor utransportation uthrough u a u tiny u capillary. u In u this u activity, u you u will
u learn u about u the u seasons u of u a u cell’s u life, u and u in u turn u better uunderstand uhow uorganisms ufunction.
