Characteristics of Life
This is the fundamental, basic unit of life that all living organisms are made of.
What is a cell?
This term describes a specific part of an organism that is designed to perform a distinct task.
What is a structure?
This system is responsible for bringing oxygen into the body and removing carbon dioxide from the blood.
What is the respiratory system?
Any microscope that uses two or more lenses to magnify an image is given this classification name.
What is a compound microscope?
This process involves particles naturally moving from an area of higher concentration to an area of lower concentration until they even out.
What is diffusion?
If touching a hot stove is the stimulus, pulling your hand away from it is called this.
What is a response?
This term describes the specific purpose, task, or job that a body part performs.
What is a function?
This structure is the long, muscular tube (often called the windpipe) that air travels down after leaving the nose or mouth on its way to the lungs.
What is the trachea?
This organelle serves as the "command center" of the cell, directing activities such as growth and movement.
What is the nucleus?
Because a cell membrane acts like a filter that lets some substances pass through while blocking others, it is described by this phrase.
What is semi-permeable or selectively-permeable?
This term refers to the sum of all chemical processes that happen within a living organism to handle energy and materials.
What is metabolism?
For the function of breathing, humans have evolved to use lungs, while fish use this structure.
What are gills?
Food travels through the esophagus into the stomach using this wave-like muscle contraction movement.
There are two organelles are found strictly in plant cells and are not present in animal cells. Name one of them.
What are the cell wall OR chloroplasts?
Blood, fat, cartilage, bones, and tendons are all examples of this specific category of animal tissue.
What is connective tissue?
These are the specific substances found in food and the environment that provide the materials and energy organisms need to grow, develop, and reproduce.
What are nutrients?
Charles Darwin observed 13 closely related species of finches on the Galapagos Islands that had structural variations in these body parts, which were all used for the function of gathering food.
What are bills or beaks?
This organ system is a massive network responsible for transporting blood, oxygen, and nutrients to all the cells throughout your body.
What is the circulatory system?
This cell structure acts as a "storage room" for nutrients, water, and waste. Plants have one large one, while animals have many small ones.
What is a vacuole?
This specific type of body tissue covers the entire outer surface of your body and lines the inner paths of organs like your intestines.
What is epithelial tissue?
A rabbit's fur changing color from brown in the summer to white in the winter is an example of this specific characteristic of life.
What is adapting to the environment?
Darwin's finches on the Galapagos Islands developed different bill shapes and sizes because they were adapted to gathering different types of this.
What is food?
Made up of the brain, spinal cord, and a massive network of pathways, this system sends electrical signals to control all body movements and responses.
What is the nervous system?
Known as the "kitchen" of the cell, this fluid-like substance contains all the vital nutrients required by the cell to carry out its life processes.
What is a cytoplasm?
Within a plant's leaves, stems, and roots, you will find three specific tissue types rather than the four found in animals. Name 2 of them.
What are photosynthetic (or storage), protective, and transport tissues?
