5 Questions
What is the main difference between unicellular organisms and multicellular organisms?
Unicellular organisms perform all life processes in a single cell, while multicellular organisms distribute functions among multiple cells.
Which organelles are mentioned in the text as common to all cells, regardless of their function and location?
Ribosomes and chloroplasts
How do unicellular organisms generally compare to multicellular organisms in terms of cell number?
Unicellular organisms are simpler because they only consist of a single cell.
Why do multicellular organisms have cells with similar basic structure and functions?
To allow each cell to undertake different functions effectively.
How do organelles contribute to the life and functions of a cell?
Organelles enable the cell to live and perform its functions.
Study Notes
Unicellular Organisms
- Unicellular organisms are made up of a single cell, e.g. Bacteria, Amoeba, Paramecium, Chlamydomonas.
- A single cell in unicellular organisms performs all life processes, including:
- Obtaining food
- Respiration
- Excretion
- Growth
- Reproduction
Multicellular Organisms
- Multicellular organisms are made up of multiple cells, e.g. some fungi, plants, and animals.
- All cells in multicellular organisms have similar basic structure and undertake similar basic functions.
- Cells in multicellular organisms have the same organelles, regardless of their function and location in the organism.
- Organelles are essential for a cell to live and perform its functions.
Explore the differences between unicellular organisms, such as bacteria and amoeba, and multicellular organisms, like fungi and animals. Learn about how unicellular organisms are made up of a single cell capable of performing all life processes, while multicellular organisms are composed of multiple cells with specialized functions.
