7th Cells and Cell Organization

Tiny structures that carry out specific functions within cells.

• Tissues
• Organelles
• Organs
• Organ systems

Two organelles that plant cells have that animal cells do not have.

• The cell membrane and a nucleus
• Mitochondria and ribosomes
• Vacuoles and cytoplasm
• Cell walls and chloroplasts

The largest organelle in a plant cell.

• Vacuole
• Golgi body
• Endoplasmic reticulum
• Mitochondria

The "brain" or "control center" of a cell that directs all of the cell's activities.

• Cell membrane
• Nucleus
• Lysosomes
• Cytoplasm

The "gatekeeper" of the cell that controls what substances enter and leave the cell.

• Cell membrane
• Chloroplasts
• Nucleus
• Mitochondria

The "conveyor belt" around the nucleus that moves materials from the nucleus and into the cell.

• Vacuole
• Ribosomes
• Lysosomes
• Endoplasmic reticulum

The "post office" of the cell that receives materials from the ER, labels them, then sends them where they need to go.

• Golgi body
• Vacuoles
• Nuclei
• Cell wall

The watery, gel-like substance that occupies all of the cell's volume between the nucleus and the cell membrane.  It surrounds all other organelles in the cell.

• Golgi bodies
• Mitochondria
• Cytoplasm
• ER

The storage area of the cell.  It can be used to store water, food, and/or waste.  In plants, it is the largest organelle.  In animals, there are multiple smaller ones.

• Mitochondria
• Vacuole
• Chloroplasts
• Nucleus

The "powerhouse" of the cell that burns food with oxygen to produce energy that the cell can use in the form of a chemical called ATP.

• Ribosomes
• Lysosomes
• Golgi body
• Mitochondria
