How can we protect ourselves from becoming infected with viruses?
Which of the following is not a type of virus?
What is the main difference between viruses and bacteria?
viruses vs bacteria
Virus: a small infectious agent that replicates only inside the living cells of an organism.
Bacteria: single-celled microorganisms that can exist either as independent (free-living) organisms or as parasites (dependent upon another organism for life).
Pathogen: a microorganism that can cause disease in its host, such as a virus, bacterium, or fungus.
Viruses vs. Bacteria
Viruses are much smaller than bacteria and can only replicate inside living cells. Bacteria are single-celled organisms that can cause disease, while viruses can only cause disease when they infect a living organism. Bacteria can be killed by antibiotics, while viruses cannot.
Did you know?
Viruses are not considered living organisms because they lack the ability to reproduce on their own and require a host cell to survive. Bacteria are the oldest known form of life on Earth, having been around for 3.5 billion years. The smallest virus is about 10 times smaller than the smallest bacteria, making it much harder to detect.
Which of the following is smaller in size, viruses or bacteria?
Do viruses have a cellular structure?
Are bacteria considered living organisms?
Bacteria: The Tiny Living Organisms
Bacteria are microscopic living organisms that can be found everywhere in nature. Bacteria can be helpful or harmful. Some bacteria help plants and animals stay healthy, while others can cause diseases. Most bacteria are harmless to humans, but it's important to practice good hygiene to stay healthy.
Bacteria are microscopic, single-celled organisms that are found virtually everywhere on Earth. They come in a variety of shapes, sizes, and colors, and can survive in many different environments.
Bacteria can reproduce very quickly, and often live in colonies that can be seen with the naked eye. Bacteria can also be either beneficial or harmful to humans, depending on the species.
Bacteria can be spread through contact with an infected person or animal, through contact with contaminated water or food, or through the air. It is important to wash your hands often and be aware of the foods you consume to help prevent the spread of bacteria.
How do bacteria get the energy they need to survive?
How do bacteria reproduce?
Which of the following is a characteristic of bacteria?
- Single-celled organisms
- Multicellular organisms
- Plant-like organisms
What role do some bacteria play in digestion?
- They cause infections and diseases.
- They have no involvement in digestion.
- They help break down food and aid in nutrient absorption.

Did you know?
Protists are the oldest and most diverse form of life on Earth, with over 100,000 known species. Protists are the only eukaryotic microorganisms that can survive in extreme environments like high temperatures or low salinity. Protists use a variety of methods to move, such as cilia, flagella, pseudopods, and gliding.
Protists: Unique Microscopic Organisms
Protists are single-celled microscopic organisms that live in many different environments. Protists can move around and are often shaped like a blob, spiral, or rod. Some protists are helpful to humans, while others can cause diseases in plants, animals, and humans.
Work together in pairs: Q: What are the three main groups of protists?
Which of the following is not a type of protist?
What is the primary characteristic that defines protists?
- They are eukaryotic organisms
- They lack a nucleus
- They are multicellular organisms
What is the primary mode of nutrition for most protists?
Protists: Tiny but Mighty!
Protists are single-celled organisms with complex structures and behaviors. They live in all kinds of habitats, from oceans to ponds to soil! Protists have a variety of shapes, sizes, and colors. Some can move around, while others have to stay in one spot. Protists are important for keeping ecosystems healthy. They are food for bigger animals, and some can even produce oxygen!
Did you know?
Protists are the most diverse group of eukaryotic organisms and contain a wide variety of species. Some protists are capable of photosynthesis and others are predatory. Protists are capable of movement and can use flagella, cilia, and pseudopods to move around.
Fungi: Nature's Decomposers
Fungi are living organisms that can't make their own food like plants do. Instead, they feed on organic matter like leaves, wood, and other decaying matter. Fungi help break down this organic matter, making it easier to be absorbed by plants, microbes, and other organisms. Fungi help keep nature healthy by recycling carbon, nitrogen, and other essential nutrients.
Fungi are organisms that belong to their own kingdom. They are neither plants nor animals, but are more closely related to animals than plants.
Fungi are decomposers. They break down dead and decaying matter, releasing nutrients back into the environment.
Fungi reproduce both asexually and sexually. Asexual reproduction occurs when a single organism produces offspring without the need for a partner, while sexual reproduction occurs when two organisms combine genetic material to produce a new organism.
Did you know?
Fungi can have a symbiotic relationship with plants; helping them to take in nutrients and grow. Fungi are the only organisms capable of producing the antibiotic penicillin. Some species of fungi can have lifespans of hundreds of years.
