This organelle is like the skin of a cell. It lets molecules in and out of the cell.
Cell Membrane
What does the Nucleus have that instructs it how to control the cell?
DNA, coded instructions
What does the Muscular System do for our body?
The muscular system helps move the parts of the body
What are the 4 Body Systems that we learned about in class?
Digestive, Nervous, Muscular, Cardiovascular
This organelle creates energy for the cell. It is sometimes called the "Powerhouse" of the Cell.
Mitochondria
The Cell Membrane has gaps called pores that allow molecules in and out of the cell.
What do the pores do to let in large molecules?
The pores can widen and close to let larger molecules into the cell.
Describe the function of the cardiovascular system. It has two main functions.
The cardiovascular system delivers nutrients/food and oxygen to other cells in the body, and removes waste (CO2).
How does the Nervous System help us run?
The Nervous System sends messages to the muscles telling them to move
This organelle controls the actions of the cell. It is like the brain of the cell.
Nucleus
What does the cytoskeleton do that is similar to our skeleton/bones?
Cytoskeleton maintains a cell's structure and shape, and helps the cell move.
What are the 3 main functions of the Nervous System?
1. Controls and coordinates the body
2. Stores memories
3. Process information from the outside world
How does the Cardiovascular System work together with the Digestive System?
The Cardiovascular System (Red Blood Cells) receives nutrients from the Digestive System (Small Intestine)
This organelle breaks down or digests things in the cell. It also destroys viruses in the cell.
Lysosomes
How does the Mitochondria create energy?
The Mitochondria chemically reacts nutrients and oxygen to turn them into energy (ATP) and waste products (Carbon Dioxide)
How do the Muscular System, Cardiovascular System, and the Digestive System help us read a book?
The Muscular System allows us to hold the book and turn the pages. The Cardiovascular System transfers nutrients and oxygen to the muscles so that they have energy to hold the book. The Digestive System passes the nutrients to the Cardiovascular System.
This organelle is covered in ribosomes and transports the proteins made by the ribosomes to the Golgi Body
Rough Endoplasmic Reticulum
How do ribosomes make proteins?
Ribosomes receive instructions from the Nucleus (RNA) and they scan the instructions to make a protein
Describe the full process of digesting and getting energy from an orange
First, your nervous system sees the orange and tells the arms/hands to pick up the orange. The hands bring the orange to the mouth. The mouth chews the orange into smaller pieces, which are swallowed down the esophagus to the stomach. The stomach mixes the chewed up orange with acid and starts digesting the orange. The chewed up orange gets passed to the small intestine where it is completely digested into nutrients and waste. The small intestine sends the nutrients to the blood and passes the waste to the large intestine. The red blood cells transfer the nutrients to all cells in the body
Why do we have a faster heart rate and breath harder when we are exercising?
Extra credit if you mention the cell part that is being used for this.
We are using more energy when we exercise, so our bodies pump blood faster through our bodies. The red blood cells transfer more nutrients and oxygen to the cells so that the cells' mitochondria can turn the nutrients and oxygen into energy.
