Kingdoms of Life

Front

What is the Kingdom Fungi?

Back

A kingdom that includes multicellular and unicellular organisms that absorb nutrients from organic material, often decomposing dead matter. Examples include molds, mushrooms, and yeasts.

Front

What are the main characteristics of the Kingdom Plantae?

Back

Multicellular, eukaryotic organisms that perform photosynthesis, have cell walls made of cellulose, and do not move. Examples include grass, trees, and ferns.

Front

Define Eubacteria.

Back

A kingdom of single-celled, prokaryotic organisms that can be found in various environments, including the human body. Some are beneficial (like those used in yogurt) while others can be harmful.

Front

What distinguishes the Kingdom Animalia?

Back

Multicellular, eukaryotic organisms that are heterotrophic, meaning they obtain energy by consuming other organisms. They are capable of movement at some stage of their life cycle.

Front

What are Protists?

Back

A diverse group of mostly unicellular eukaryotic organisms that can be autotrophic or heterotrophic. Examples include amoebas and algae.

Front

What is the role of fungi in ecosystems?

Back

Fungi decompose organic matter, recycling nutrients back into the ecosystem, and can form symbiotic relationships with plants (mycorrhizae).

Front

What is photosynthesis?

Back

The process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is a prokaryote?

Back

An organism that lacks a nucleus and membrane-bound organelles. Examples include bacteria and archaea.

Front

What is a eukaryote?

Back

An organism whose cells contain a nucleus and membrane-bound organelles. Examples include plants, animals, fungi, and protists.

Front

What is the significance of cell walls in plants?

Back

Cell walls provide structural support, protection, and help maintain turgor pressure in plant cells.
