In science class, Cindy and Jane are conducting an investigation on living things to find out what the * difference is between unicellular and multicellular organisms. First, they use a microscope to observe different types of organisms. Next they go to the library to do more research on the organisms they observed with the microscope. Afterward, Cindy and Jane reviewed the observations and data results they recorded to come to a conclusion to the question: What is the difference between a unicellular organism and a multicellular organism?

In science class, Cindy and Jane are conducting an investigation on living things to find out what the * difference is between unicellular and multicellular organisms. First, they use a microscope to observe different types of organisms. Next they go to the library to do more research on the organisms they observed with the microscope. Afterward, Cindy and Jane reviewed the observations and data results they recorded to come to a conclusion to the question: What is the difference between a unicellular organism and a multicellular organism?

Unicellular organisms do not respond to stimuli in the environment. Multicellular organisms do respond to stimuli in the environment.
• Unicellular organisms are producers and multicellular organisms are consumers
Unicellular organisms perform all functions for life with one cell. Multicellular organisms have many cells that work together to keep them alive.
Unicellular organisms are heterotrophs and multicellular organisms are autotrophs.

Answer 1

Based on their investigation, Cindy and Jane concluded that the main difference between unicellular and multicellular organisms is that unicellular organisms are single-celled and perform all functions for life with one cell, while multicellular organisms are made up of many cells that work together to keep them alive. Additionally, they found that unicellular organisms do not respond to stimuli in the environment, are producers, and are heterotrophs, whereas multicellular organisms do respond to stimuli in the environment, are consumers, and are autotrophs. These differences in structure and functions help to distinguish between the two types of organisms.
