1st topic: classification of living organisms

what are groups of vertebrates?

• fish, amphibians, reptiles, birds, and mammals.

• insects, arachnids, crustaceans, and mollusks.

• fungi, bacteria, viruses, and protozoa.

• trees, shrubs, grasses, and flowers.

What are the characteristic features of fish?

• They are mammals with fur and live on land.

• They have gills throughout their life.

• They are reptiles with feathers and lay eggs in trees.

• They have fins and are warm-blooded.

What are the characteristic features of Prokaryotes?

• They have a nucleus and mitochondria.

• They are usually unicellular, have no nucleus, and have a circular loop of DNA free in the cytoplasm.

• They are multicellular and have cell walls made of cellulose.

• They have linear DNA and lack cell walls.

What are the main domains?

• Archaea: single-celled organisms that often live in extreme environments.

• Bacteria: single-celled organisms with distinct genetic makeup from archaea.

• Eukarya: includes all organisms with eukaryotic cells, such as protists, fungi, plants, and animals.

• Prokarya: a term often used interchangeably with bacteria, but not a recognized domain.

What are the characteristic features of flowering plants?

• They are plants with roots, stems, and leaves.

• They reproduce using spores and cones.

• They have a single type of leaf structure throughout their life cycle.

• Their seeds are produced inside an ovary, in the flower.

What is an organism?

• An organism is a complete living thing

• An organism is a type of cell

• An organism is a non-living entity

• An organism is a collection of tissues

Describe the binomial naming

• In this system, each organism is given a two-part Latin name: Genus followed by species Genus species

• All organisms are named using a single Latin name.

• The naming system uses three parts: Genus, species, and family.

• Names are written in English and do not follow any specific format.

Define movement

• Movement is the ability of an organism, or part of it, to change position or place.

• Movement refers to the speed at which an organism can grow.

• Movement is the process of an organism reproducing its species.

• Movement is the ability of an organism to remain stationary.

Is breathing the same as respiration?

• Yes, they are the same process.

• No, breathing is a process that facilitates respiration but is not considered one of the seven fundamental characteristics that define life.

• Breathing is a type of respiration.

• Breathing and respiration are both essential for life.

Why are viruses not living?

• They don't have ALL of the 7 characteristics of the living organisms.

• They can reproduce on their own without a host.

• They have a cellular structure similar to bacteria.

• They can metabolize nutrients independently.
