Genesis 1:25-26 KJV25 And God made the beast of the earth after his kind, and cattle after their kind, and every thing that creepeth upon the earth after his kind: and God saw that it was good.26 And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth

OBJECTIVE

Identify the characteristics of all living things.

Learning objectiveIdentifying the variety of living things by direct observation and describe the variety of organisms in terms of characteristics.

Vocabulary

• First lets write the vocabulary definitions.

• Classification: the process of grouping similar things together

• Kingdom: A major, large group of similar organism• Species: is a unique kind of organism• Phylum: is a major group within a kingdom• Genus: is a subdivision of a family

Now lets read pages 94 – 98.

•What is classification?

Classification is the grouping of living organisms according to similar structures and functions.

Grouping living things

Scientists classify living organism into major, large groups called kingdoms. All members of each kingdom have certain

characteristics.

5 KingdomsOne classification system divides all organisms into five kingdoms: Animals, Plants, Fungi , Protists and Bateria or Monera.

What characteristics does each kingdom have?

Animals: Scientists classify animals together because animals are made of many celled and becase thet feed on other living or onceliving thing.

Plants: The plants also have many celles, but they make their own food.

Fungi: Most fungi also are many celled organism. However, they don´t make or eat food. They absorb it, usually from the reamins of other organisms. Some make food, as plants do. Others take in food, as animals and fungi do.

Bacteria or Monera: These one are all one-celled. Their cells have no nucleus. Most feed the way fungi do, but some make their own food.

Some scientist group all bacteria in one kingdom. Others separate them into two kingdoms.

5 Kingdoms

Moneran

• One celled• No separate nucleus• Example: bacteria

Protist

• Most one celled• Have nucleus and other cell

structures• Examples: algae, amoeba

Fungus

• Many celled• Cannot move• Absorb nutrients from other

organisms• Examples: mushrooms,

yeast, molds

Plant

• Many-celled• Cannot move• Use energy from the sun to

make sugars• Examples: trees, flowers,

ferns

Animal

• Many-celled• Most can move• Get energy by consuming

other organisms• Examples: invertebrates,

fish, birds, mammals
