During this unit we spent time learning about different cells. We learned about the differences between plant and animal cells, as well as the difference between prokaryotic and eukaryotic cells. We learned many different organelles inside of a cell and what function they carry out.


 * Vocab**:


 * Cell Membrane:** A lipid bilayer that regulates what goes in and out of the cell.
 * Cell Wall:** Only in plants, made of cellulose, holds the cells structure.
 * Centrioles:** Only in animal cells, they help the cell divide.
 * Chromosomes:** Strings of DNA inside of the nucleus.
 * Cytoplasm:** A jelly like substance that holds all organelles and allows for movement.
 * Cytoskeleton:** Microtubules that support the cell.
 * Endoplamic Reticulum (ER):** A network of tubes that provides transportation within the cell.
 * Flagella/Cilia:** Only in animal cells, tail or hair like projections that help with movement.
 * Golgi Apparatus:** A flat stack of sacs that modify and package cellular materials.
 * Lysosomes:** Dispose of waste and other worn-out organelles.
 * Mitochondria:** A peanut shaped organelle that is the powerhouse of the cell, and makes energy.
 * Nucleolus:** Helps make proteins, and the RNA is inside.
 * Nucleus:** The brain of cell held in a nuclear envelope, that controls all activities.
 * Plastids (Chloroplasts):** Only in plant cells, hold pigment and carry out photosynthesis.
 * Ribosomes:** Small structures found on the rough ER that produce proteins.
 * Vacuoles:** A saclike structure that stores food, water, and waste.

**Objectives:** Be able to name all organelles of animal cells. Be able to name all organelles of plant cells. Be able to differentiate a plant cell and an animal cell. Know the functions of all organelles. Be able to differentiate between prokaryotic and eukaryotic.
