Being Multicellular
• Being Multicellular – Division of labor – Self- vs non-self – Communication & Coordination – Bulk transport
• Plant structure – Meristems and primary growth – Tissue systems – Stem structure – Roots

Brief history of life
Cells of this colonial alga are connected, but it is not truly multicellular
