What is the purpose of the Tree of Life model?

To show how all species are related.

100

What are microbes?

Tiny organisms that can be bacteria, fungi, protists, etc.

100

What structure in bacteria helps them move?

Flagella.

100

What material makes up the cell walls of fungi?

Chitin.

100

Name one type of protist.

Algae, protozoa, or slime moulds.

200

Name one characteristic that helps scientists classify organisms.

Physical characteristics (e.g., cell structure, body type).

200

Name one place where microbes can be found.

Almost everywhere, including soil, water, air, and on living organisms.

200

Name one shape bacteria can have.

Spherical, rod-shaped, or spiral.

200

What is mycelium?

A network of hyphae that absorbs nutrients.

200

What do animal-like protists eat?

Bacteria or other small organisms.

300

True or False: The Tree of Life includes only animals and plants.

False, it includes all types of organisms.

300

True or False: All microbes are harmful to humans.

False, some are helpful to humans and the environment.

300

What is the role of bacteria in decomposition?

They break down dead organic material.

300

Name one way fungi contribute to the ecosystem.

They decompose dead matter and recycle nutrients.

300

How do plant-like protists benefit aquatic ecosystems?

They produce oxygen through photosynthesis.

400

Why is classification important in science?

It helps scientists organise and study relationships between species.

400

List two types of microbes.

Bacteria, fungi, protists, viruses.

400

What are two ways bacteria help human health?

Aid in digestion and produce vitamins in the human gut.

400

What is a symbiotic relationship? Give one example involving fungi.

A close relationship where both organisms benefit, e.g., mycorrhizal fungi and plant roots.

400

Describe one way that protozoa move.

Cilia, flagella, or pseudopods.

500

Describe one way organisms are grouped on the Tree of Life.

By shared characteristics or genetic similarities.

500

How do microbes impact the environment?

They recycle nutrients, decompose organic matter, and support ecosystems.

500

Name one example of a harmful bacteria.

Streptococcus (causes strep throat), Salmonella (causes food poisoning).

500

How do fungi reproduce? Name the reproductive cells.

By releasing spores.

500

Why is algae important for aquatic life?

Algae form the base of the food chain and produce oxygen.
