1. Eukaryotic Cell Structure

2. Eukaryotic Cell Structure
Organelles are membrane-bound structures in eukaryotic cells
Each organelle has a function
Boundaries
Assembly and storage
Energy production
Support and movement

3. Cell boundaries
Plasma membrane – a flexible boundary that allows some materials, like water and nutrients, into the cell and lets waste leave
Cell wall – a rigid structure outside the plasma membrane that gives support and protection, found in plants, fungi and bacteria
Made of cellulose

4. Cell boundaries
Plasma membrane
Cell wall

5. Cell boundaries Nuclear envelope – surrounds nucleus
Nucleus – contains chromatin, strands of DNA, the instructions for making proteins that are needed for the cell to function
Nucleolus – an organelle within the nucleus that makes ribosomes
Cytoplasm – clear fluid inside a cell

7. Assembly and storage
Endoplasmic reticulum (ER) – site of chemical reactions, makes lipids
Ribosomes – attach to ER, form rough ER makes proteins
Golgi apparatus – takes proteins and packages them for delivery

8. Assembly and storage Endoplasmic reticulum (ER) Ribosomes
Golgi apparatus

9. Assembly and storage
Vacuoles – spaces for temporary storage of food, enzymes, waste
Lysosomes – contain digestive enzymes, digest worn out organelles, food, bacteria
