Science 4A Flashcards
A group of cells that performs a particular function in a multicellular organism is called a __________.
Tissue (blow your nose in one?)
A _________ ________ is made of many cells that usually live together but could survive alone. (Live in a colony like bees)
Colonial Organism
List the four levels of cellular organization, from least complex to most complex.
cell
tissue
organ
organ system
Put these in order from least complex, to most complex
Digestion system
Stomach
bacteria in colon
tissue in stomach
bacteria in colon (cell)
Lining in stomach (tissue)
Stomach (organ)
Digestion system (organ system)
What is it called when tissues and organs have different jobs and they all work together in a multicellular organism?
division of labor

Organ
________ are groups of tissues that work together to accomplish a particular func- tion. A leaf, for example, is a plant organ
Organs
Give an example of an organ on a tree?
A leaf
Veins are a leaf tissue made mostly of tubular cells. Veins transport liquids and strengthen the leaf
Groups of similar cells working together to perform a particular function is a _______
Tissue
Is a colony cell the same as a tissue cell? Unlike a cell from a colony, a cell from a tissue normally cannot survive by itself
NO!
Unlike a cell from a colony, a cell from a tissue normally cannot survive by itself
Give an example of a tissue in a tree?
The bark
