What is a unicellular organism
An organism made up of only one cell
What is an organism
An organism is a living system with parts that work together to carry out the processes of life
What is a multicellular organism
An organism that is made up of two or more
What is a vertebrae
An animal with a backbone
What is an invertebrate
An animal without a backbone
What is fungi
Organisms that usually obtain nutrients from dead or decaying matter and cannot carry out photosynthesis
What is a protist
An organism that is neither plant nor animal but shares many of the same characteristics of both
What is bacteria
Bacteria is The most basic of all unicellular organism and it lacks a nucleus
Give an example of the unicellular organism
Diatom
Given example of a multicellular organism
Plants and animals
Give an example of a animal with the vertebrate
Moose salmon or Bluejay
Given example of a I invertebrate
Spider shrimp or snail
Give an example of a fungi
Mushrooms
Give an example of a protist
Volvox
Give an example of bacteria
Escherichia coli
What are the five major groups
Animals, bacteria, plants, protists, and fungi
How do you classify living things
when you examine the organisms in each group, you see that they have important characteristics in common. This method of classification allows scientists to better understand the diversity of life on earth for example a dog with reclassified animals because it has a backbone
How does Paramecium obtain nutrients
When the oral groove contains cilia that creates a current that draw food into a cavity once the cavity is filled the food is enclosed in vacuole where it is slowly digested as the food vacuole travels through the cellS NUTRIENTS DIFFUSE through the vacuoles membrane into the cytoplasm
How does amoeba obtain nutrients
When the amoeba needs nutrients chemicals are released into the vacuole to break down the store food the food particles then able to diffuse into the cytoplasm of the cell
How do both Paramecium amoeba exchange gases
In unicellular organisms oxygen diffuses across the cell membrane into the cell, carbon dioxide diffuses out of the cell once the concentration of carbon dioxide is higher inside the cell that it is outside of the cell
How do unicellular organisms respond to the environment
Unlike humans five senses on unicellular organisms do not have the ability they must sense their surroundings and other ways some bacteria can detect chemicals such as sugar in their environment and move toward them Photosynthetic protist called Euglena can detect light using special sensors all organisms are able to sense their environment and someway and respond to it
What is movement
The change in shape or figure of all or part of an organism a characteristic of living things
What is locomotion
Locomotion is the movement that takes an object from one place and its environment to another a characteristic of animals animallike protests and some bacteria but not Plants or fungi
What is cellular differentiation
The process by which a cell become specialized to perform a specific function
