CELLS

CELL WALL

• The tough outer layer of the cell
• Protects and supports the cell
• Made of a strong material called cellulose
• Water and Oxygen can easily pass through
• Animal cells do not have a cell wall

CELL MEMBRANE

• Second barrier of a plant cell
• It controls what comes into the cell and what goes out
• Everything the cell needs passes through the cell membrane
• All excess materials go out through the cell membrane
• Prevents harmful materials from getting into the cell

NUCLEUS

• A large oval shaped structure
• Directs all of the cell's activities
• The "brain" of the cell

NUCLEAR ENVELOPE

• The outer protective shell of the nucleus
• Protects the Nucleus
• Materials go in/out of the nucleus through the pores in the nuclear envelope

CHROMATIN

• Thin strands floating in front of the nucleus
• Contain genetic material
• Give instructions to the nucleus on the cell's function

NUCLEOLUS

• Small objects floating inside the nucleus
• Where Ribosomes are produced

CYTOPLASM

• The region between the Cell Membrane and the Nucleus
• Filled with clear, thick, gel like fluid
• The fluid is constantly moving
• Many of the cells organelles are found here

MITOCHONDRIA

• Rod shaped structures
• Convert energy in food into energy the cell can use
• Known as the "powerhouse" of the cell

ENDOPLASMIC RETICULUM

• Passage ways in the cytoplasm
• The passage ways carry materials from on part of cell to another

RIBOSOMES

• Grain like bodies
• Ribosomes produce proteins

GOLGI BODIES

• Receive newly formed materials packages and distributes them
• Also releases materials outside the cell
• Look like flattened sacs and tubes

CHLOROPLASTS

• Large green structures floating in the cytoplasm
• Animal cells do not have chloroplasts
• Captures energy from sunlight and produces food for the cell
• Makes leaves green

VACUOLES

• Large sac in the cytoplasm
• Stores food, waste, and other materials
• Some animal cells do not have a vacuole

LYSOSOMES

• Small round structures
• Contains chemicals that breaks down certain materials in the cell
• Thought of as the "cleanup crew"
