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
