Organells
Inside of every cell are working structures to help the cell function.
Organelles
Clear gel-like fluid inside of a cell.
Cytoplasm
Thin layer which surrounds the cytoplasm
Cell membrane

What is the largest living structure on Earth?
The Great Barrier Reef
What is something that only plant cells have?
Chloroplasts
rod-shaped; convert the energy in to food energy that the cell can use to function; the "powerhouse"
Mitochondria
Plant cells only captures energy from sunlight and changes it into energy(sugar) for the plant.
Reason why plants are green
Chloroplasts
What is interphase?
A single cell grows in size and doubles its contents.
What is the longest type of cell in the body?
The nerve cell
What does cell division allow?
Organisms growing larger and reproduction
A large oval in the center of the cell; carries the genetic material (DNA) surrounded by this nuclear envelope.
What is a cell wall?
plant cells only; thin layer which surrounds the cytoplasm.
What is mitosis?
The contents are divided in half inside the single cell
What is the largest organ in the human body?
Skin
What is active and passive transport?
Active is molecules moving from low concentration to high concentration and energy is required.
Passive is where molecules move from high concentration to low concentration and no energy required.
What is a Endoplasmic Reticulum (ER)?
A network of folded membranes process substance (digestion) and store energy. BATTERY
What are vacuoles?
Storage centers; holds water, food, and waste products of the cells; think vacuum cleaner.
What is cytokinesis?
The cell's cytoplasm divides in 2, each obtaining its own set of organelles; there are now 2 cells.
When was the structure of DNA discovered?
1953
What are all the things Organelles have?
A specific job
A different structure
Some are only found in plant cells
Some are only found in animal cells
Some are found in both
What is the Golgi Apparatus?
receives, packages and distributes materials from the ER to the parts of or outside of the cell "Mail Room"
What are ribosomes?
Make proteins for use in the cell; little spheres that either float in the cytoplasm or are attached to the ER.
What are the 4 types of mitosis?
Prophase, Metaphase, Anaphase, and Telophase
True or False: The "fresh" smell after its been raining comes from trees breathing.
