100

Plants are classified as producers because they make food through this process.

What is photosynthesis?

100

This tissue transports water through the plant.

What is xylem?

100

Invertebrates are animals that do not have this structure.

What is a backbone?

100

This phylum includes flatworms.

What is Platyhelminthes?

100

This phylum includes clams, snails, and squid.

What is Mollusca?

100

All chordates have this support rod at some point in life.

What is a notochord?

200

This waxy adaptation helps plants reduce water loss on land.

What is the cuticle?

200

This tissue transports sugar through the plant.

What is phloem?

200

This phylum includes sponges.

What is Porifera?

200

This phylum includes roundworms.

What is Nematoda?

200

This mollusk structure secretes the shell.

What is the mantle?

200

A vertebrate is a chordate with this structure.

What is a backbone?

300

This plant group lacks vascular tissue.

What are mosses/bryophytes?

300

These small openings allow gas exchange in leaves.

What are stomata?

300

Sponges are different from most animals because they lack these.

What are true tissues?

300

This phylum includes segmented worms such as earthworms.

What is Annelida?

300

This phylum includes insects, spiders, crustaceans, and their relatives.

What is Arthropoda?

300

This chordate structure develops into the brain and spinal cord in many vertebrates.

What is the dorsal nerve cord?

400

This plant group produces flowers and fruits.

What are angiosperms?

400

These cells open and close the stomata.

What are guard cells?

400

This type of symmetry is arranged around a central point like a wheel.

What is radial symmetry?

400

This term means the concentration of sense organs near the head.

What is cephalization?

400

Arthropods must do this because their exoskeleton does not grow with them.

What is molting?

400

These chordate structures may become gills in aquatic animals.

What are pharyngeal slits?

500

These seed plants produce “naked seeds” not enclosed in fruit.

What are gymnosperms?

500

This plant hormone helps a plant bend toward light.

What is auxin?

500

This body plan has left and right sides and is linked to cephalization.

What is bilateral symmetry?

500

This is a fluid-filled body cavity fully lined with mesoderm.

What is a true coelom?

500

This phylum has a water vascular system and tube feet.

What is Echinodermata?

500

This is an example of a chordate that is not a vertebrate.

What is a tunicate?
