Diversity of Living Things Classification The Five Kingdoms Adaptation Grade 6 – Cluster 1 Diversity of Living Things Classification The Five Kingdoms Adaptation

Classification Definition: Classification is the process of grouping things according to similarities and differences (ex. colour, age, size) Sorting things into groups helps put order into our lives. The categories that are made and the groups that belong in them reflect patterns in the world around us. Why is it important that biologists find a way to classify Earth’s millions of species?

Classification Systems & Taxonomy Definition: classification systems are organized structures for arranging and classifying The purpose of a classification system is to allow the accurate identification of a particular organism, no matter where it exists.

Taxonomy Definition: Taxonomy is the science of classifying organisms

Question: What’s the difference between taxonomy and classification?

Activity Create a classification system for the following animals: Eagle, Wolf, Fox, Hyena, Shark, Cheetah, Wolverine, Frog, Hippo, Tiger, Panda, Cow, Penguin, Giraffe, Koala, Cobra, Trout,  Black Bear, Human In writing, briefly explain your classification system.  Develop a system to classify common objects into groups or subgroups, and provide a rationale Identify advantages and disadvantages of having a common classification system for living things, and recognize that systems change with new discoveries Activity

The Five Kingdoms

Monera (bacteria) Protist Fungi Plant Animal The Five Kingdoms

Monera Simplest form of life Do not have a nucleus Absorb food These are bacteria and cyanobacteria which is also referred to as blue green algae Bacteria can be found anywhere, it can grow in hot or cold places Bacteria can feed on many different things

Protist Single Celled All have a nucleus Absorb, ingest, and/or photosynthesize food Examples are: paramecium, amoeba Protist

Activity – Protist VS. Monera Complete the Venn Diagram using your notes on the kingdoms Protist and Monera. Activity – Protist VS. Monera

Animals Largest group of living things on earth Have many cells Cannot make their own food More than a million different kinds of species Able to move Examples; insects mammals, amphibians Animals

Vertebrates or Invertebrates?

Vertebrates are animals with an internal skeleton made of bone. Classified into five groups: fish, amphibians, reptiles, birds, and mammals. 2% of the animal species are vertebrates. Vertebrates

Invertebrates Invertebrates are animals without a backbone. Arthropods, Mollusc 98% of animal species are invertebrates. Invertebrates

Invertebrates Sponges Echinoderms Cnidarians Molluscs Arthropods Annelids Invertebrates

Sponges are a group of invertebrates with about 10,000 species.

Adult sponges are non-moving and live attached to hard rocky surfaces, shells, or submerged objects

The larvae are free-swimming. Sponges

Most sponges live in salt water but a few species live in freshwater habitats.
