What are cells?
Cells are the most basic unit of life.
• Some living organisms are made of a single cell (unicellular).
• Others are made of many cells (multicellular).

Cell Theory
• Cells are the basic unit of life.
• All living things are made of one or more cells.
• Cells come from other cells.Flash Card Review

What is the difference between a plant and animal cell?
Let’s take a look inside the cells:
The parts that make up a cell are called organelles.

Cell Organelles & Their FunctionsOrganelle Function
Cytoplasm • Jelly-like fluid that fills up the space between organelles, carries nutrients to all organelles
Mitochondria • Structures where energy is produced
Endoplasmic Reticulum • Complexly folded organelle that is responsible for regulating and producing proteins and other molecules, located near the nucleus
Ribosomes • Protein production site, tiny structures found in the cytoplasm and on the endoplasmic reticulum
Nucleus • Part of cell that directs all functions of the cell and contains DNA for replication and differentiation
Cell Membrane • Barrier around an animal cell which allows certain kinds of materials in and out of cell
Golgi Bodies • Part of cell that processes and packages lipids and proteins
What are the functions of organelles found only in plants?
Cell Wall
Chloroplasts
Larger Vacuole
What is each organelle's function ?Think about your response and Click to see if you got it
Rigid layer of a plant cell that provides protection and structure
Found only in plants; captures sunlight and converts it into food energy
Organelle used to store food
