1. Types of Cells Prokaryotic (prokaryotes): NO nucleus.
Examples: Bacteria, single- celled organisms, microscopic
Eukaryotic (eukaryotes): Nucleus
Examples: plants, animals, some single-celled organisms,

2. Important Cell Structures
Nucleus: stores genetic information.
Endoplasmic Reticulum: a network of thin, folded membranes that produces proteins. Part of it is covered by ribosomes, the organelles that make proteins.
Golgi Apparatus: stacks of membrane-enclosed spaces that process, sort, and deliver proteins.

3. More Important Cell Structures
Mitochondria (singular: mitochondrion): supply energy to the cell.
What type of cell would have more mitochondria, a muscle cell or a skin cell? Why?

4. Plant Cells
Cell Wall: surrounds the cell membrane, providing protection, support and giving shape to the cell.
Found in: plant, algae, fungi and most bacteria.
Chloroplast: organelles that carry out photosynthesis, to convert light energy into molecules that the cell can use.
Vacuole: fluid-filled sac used for storage of water, salt and other nutrients.
