Building Blocks
This is the basic functional unit of all living things.
What is a cell?
This vascular tissue is responsible for transporting water from the roots up to the leaves.
What is xylem?
This term describes the process of maintaining a stable internal environment despite external changes.
What is homeostasis?
The level in the hierarchy that represents a complete, individual living thing.
What is an organism?
The largest living organism on Earth.
What is a fungus? This humongous fungus species covers over 2,000 acres underground. While it looks like separate mushrooms, its tissue is all part of one single, giant hierarchical structure.
A group of similar cells working together to perform a specific function is known as this.
What is tissue?
This tissue transports sugars and nutrients produced in the leaves to the rest of the plant.
What is phloem?
This is the term for when a cell develops a specific shape or feature to perform a particular job.
What is Specialization (or Differentiation)?
This word describes the "ranking" or "levels" of organization from small to large.
What is a hierarchy?
The speed, in mph, that your Nervous System can send impulses at. Closest answer gets the points!
What is Nerve impulses can move at speeds of up to 270 mph—faster than a Formula 1 race car!
Arrange these in order from simplest to most complex: Organ, Cell, Organism, Tissue, Organ System.
What is cell, tissue, organ, organ system, organism?
Together, the xylem and phloem make up this "transportation" organ system in plants.
What is the Vascular System?
In the body, the "Form" of a structure is its Structure, while the "Job" it does is its ________.
What is function?
This level of organization is formed when multiple organs work together to perform a major body function.
What is an organ system?
Some organisms, like the Axolotl, have the ultimate differentiation superpower. They can regrow entire what?
What are organs, limbs, + tails!
Heart, lungs, and kidneys are all examples of this level of organization.
What is an organ?
The leaf of a plant is considered this level of organization because it contains multiple types of tissues working together.
What is an organ?
Describe how the respiratory system and circulatory system work together to achieve homeostasis.
- The respiratory system takes in oxygen
- the circulatory system then transports that oxygen to cells via blood.
- Both must work together to provide fuel for cellular respiration and remove waste ($CO_2$).
Explain the difference between specialization and differentiation in a multicellular organism.
Differentiation is the process of a cell changing into a specific type; Specialization is the result (having a specific structure suited for a specific function.)
The xylem in a Coast Redwood tree is so efficient it can pull water against gravity to a height of over how many feet?
What is over 380 feet? (about the height of a 35-story building)
Explain why a single cell cannot be considered an organ, even if it performs a vital function.
An organ requires multiple types of tissues working together.
A single cell lacks the complexity and specialized tissue layers that define the organ level.
If you were creating a model of a plant's hierarchy, which structure would represent the "Organ System" level?
What is The Shoot System (leaves, stems, flowers) or the Root System?
Predict what would happen to the hierarchical organization of an organism if the process of differentiation suddenly stopped.
The organism would fail to develop complex structures. Without differentiation, all cells would remain identical and wouldn't be able to form the specific tissues (muscle, nerve, etc.) needed to build organs.
This term describes how different organs rely on one another to keep an organism alive.
What is interdependence?
The human body contains about HOW MANY different cell types, which are the smallest independent living units. These cells, along with tissues, organs, and systems, demonstrate "synergy" all working together.
What is 200 different cell types?
