Special Structures –

Heterocysts – Contain enzymes for conducting nitrogen fixation. Nitrogen fixation is the process of bacteria capturing N in gas form w/ enzymes in their body.

Akinetes It serves as a survival structure. It is a resting cell of cyanobacteria and unicellular and filamentous green algae.[2] Under magnification, akinetes appear thick walled with granular-looking cytoplasms.

Trichomes – Stacks of cells

Fungi

Eurkaryotic Cells

Most are multicellular but some are unicellular

Nutrition – Release digestive enzymes into environment & then absorb nutrients from broken down organic material.
