Carbon Cycle Supports Life on Earth

Life on Earth is only possible with carbon. Organisms on Earth rely on carbon for the production of molecules used in life functions. Various processes in the environment cycle carbon. In the ocean, the main producers in this cycle are plant-like microscopic organisms called phytoplankton.

1) Which model below best identifies how phytoplankton cycle carbon between two of Earth’s spheres?

2) Complete the model below to illustrate the process occurring in the mitochondria of cells during high intensity exercise. . Your model should include all inputs of both matter and energy and identify the process involved. [1]

Part 2

See, Think, Wonder

Directions:

View the image. Discuss in your groups what you see, think, wonder. Focus on the different parts.

Part 3

Stop n'Jot

Organelle: Means "Little Organ". Structure that has one or more specific jobs to perform in the cell, much like an organ does in the body.

Key Concept: Some organelles can be found in both, plant and animal cells. Some organelles are specific to plant or animal cells.

✴️These are not ALL the organelles. Just the organelles the regents focuses on.

Part 4

Research on Ribosomes

Culminating Question:

What do Ribosomes do and why are they important for our cells?

Ribosomes: The Cell’s Protein Builders

Inside every cell, tiny structures called ribosomes work like factories that build proteins. Even though ribosomes are extremely small, they are essential for life because cells cannot function without the proteins they create. Ribosomes read the genetic instructions sent from the DNA and use that information to assemble proteins that the cell needs to survive and carry out its daily activities.

Ribosomes build proteins by joining amino acids together in a long chain. The order of the amino acids must be exact because each protein folds into a specific shape. That shape determines the protein’s job in the cell. If the amino acids are out of order, the protein will not fold correctly and cannot function.

The proteins ribosomes make have many different roles in the body. Some proteins become enzymes, which speed up chemical reactions. Others form antibodies, which help the immune system fight germs. Ribosomes also make neurotransmitters, which allow nerve cells to communicate, and hormones, which help the body regulate processes like growth and metabolism. Ribosomes even build cell receptors, which sit on the cell membrane and allow the cell to receive signals from the environment or from other cells.

Ribosomes can be found in two main places inside the cell. Some float freely in the cytoplasm, where they make proteins that stay inside the cell. Others attach to the rough endoplasmic reticulum, where they make proteins that will be transported, packaged, or sent out of the cell to other parts of the body.

Because ribosomes follow DNA instructions so precisely, they help ensure that traits are passed from parent to offspring. The DNA provides the code, and the ribosomes build the proteins that make those traits appear.
