Biology Classification Test on Animals and Plants

Classification of Living Things

• Students will match sentences to classify living things into categories: animals, plants, vertebrates, and invertebrates.
• Classification involves identifying characteristics to group living things into specific categories.

Characteristics of Animals

• Amphibians are characterized by their ability to live in both water and on land.
• Birds are characterized by the presence of feathers, wings, and the ability to fly.
• Fish are characterized by their ability to live in water and breathe through gills.
• Mammals are characterized by the presence of hair, milk production, and warm-bloodedness.
• Reptiles are characterized by the presence of scales, laying eggs, and cold-bloodedness.

Invertebrates

• Mollusks are characterized by the presence of a soft, unsegmented body, often with a shell.
• Flatworms are characterized by their flat, soft body and simple organ structure.
• Annelids are characterized by their segmented body and setae (bristles).
• Arthropods are characterized by their jointed limbs, exoskeleton, and segmented body.
• Sponges are characterized by their simple, porous body and lack of organ structure.

More Invertebrates

• Echinoderms are characterized by their radial body symmetry, spiny skin, and water vascular system.
• Cnidarians are characterized by their stinging cells, simple nervous system, and radial body symmetry.
• Arachnids are characterized by their eight legs, simple eyes, and book lungs.
• Centipedes are characterized by their long, segmented body, many legs, and simple eyes.

Types of Feeders

• Herbivores are plants-eaters, feeding on plants and algae.
• Carnivores are meat-eaters, feeding on other animals.
• Omnivores are both plants-eaters and meat-eaters, feeding on a variety of food sources.
• Detritivores are decomposers, feeding on dead and decaying organic matter.
• Scavengers are opportunistic feeders, feeding on carrion and other dead organisms.
