Vocabulary
of Organisms and Ecosystems
Turning Back Time: A Biologist's Adventure introduces learners to key biological terms that are important for understanding the structures and systems that support life. These terms are integrated into the story, providing learners with the opportunity to apply their knowledge to real-world biological and environmental challenges.
- Cell differentiation:
The process by which unspecialised cells develop into specialised cells with specific functions. This is important for the formation of the different types of cells required to form tissues and organs. Emily needs to understand this concept in order to select the right cells for ecosystem restoration.
- Stem cells:
Undifferentiated cells capable of giving rise to specialised cells. In the story, Emily uses stem cells to restore extinct species, emphasising the potential of stem cell research in conservation.
- Tissue:
A group of similar cells that cooperate to perform a specific function. Examples include vascular tissue in plants (xylem and phloem) and epithelial tissue in animals. For Emily, understanding tissue structure is key to studying plants and animals from the past.
- Organ:
A structure made up of different tissues that interact to perform specific functions. In the story, Emily explores organs such as the stomach, where different tissues work in combination to digest food.
- Organ system:
A group of organs that work together to perform complex biological functions. Examples include the digestive, circulatory and nervous systems. Emily uses her knowledge of organ systems to help animals survive in the restored ecosystem.
- Neurons:
Specialised cells that transmit electrical impulses in the nervous system. Emily uses her understanding of neurons to communicate with a primitive tribe, creating a signalling system using gestures.
- Root hair cells:
Specialised plant cells that increase surface area for water and mineral absorption. Emily modifies these cells to accelerate plant growth in areas devastated by volcanic eruptions, helping to restore ecosystems.
- Xylem and phloem:
Tissues in plants that transport water, nutrients and food. Xylem carries water and dissolved minerals from the roots, while phloem transports sugars produced during photosynthesis. Emily uses these tissues to promote plant growth during ecosystem restoration.
- Epithelial tissue:
A type of tissue that lines the surfaces and cavities of organs and structures. It has protective functions and is involved in secretion. Emily uses epithelial tissue concepts to purify polluted areas during her mission.
- Specialisation:
The adaptation of cells to specific roles within multicellular organisms. Emily's mission depends on understanding how cell specialisation contributes to the functioning of complex organisms and ecosystems.

Background Story:
Earth is in a dire environmental crisis due to rampant destruction. Biologist Dr. Emily Carter is tasked with using time travel technology to journey to the past, collect DNA from extinct plants and animals, and restore the current ecosystem.
Chapter 1: The Mission Begins
In the underground headquarters of the International Environmental Restoration Agency, Emily is in a final meeting with her colleagues.
"Emily, this mission is crucial for the future of our planet," her supervisor James said solemnly. "You must travel back in time to collect cells from extinct species."
Emily took a deep breath and nodded. "Understood. I need to have a clear understanding of cell differentiation to succeed."
"Good. Prepare for departure. We believe in you," James encouraged.
