The outer covering of all cells, which allows things to pass both into and out of the cell.
What is the cell membrane?
100
Plants with tubes or channels for water and nutrients to travel through are called _________ plants.
What are vascular plants?
100
Vertebrates are animals that have this.
What is a backbone?
100
Invertebrates are animals that do not have this.
What is a backbone?
200
Too small to be seen by the naked eye
What is microscopic?
200
The stiff, strong outer covering that plant and bacteria cells have, but animal cells do not.
What is the cell wall?
200
Plants that do not have tubes or channels, but which absorb their water like a sponge, are called __________ plants.
What are nonvascular plants?
200
This group of vertebrates have feathers, lay eggs, and are warm blooded. They can usually fly.
What are birds?
200
These invertebrates have a soft body and a muscular foot. The group includes snails, slugs, mussels, and clams.
What are mollusks?
300

What are plants and animals?
300
The "brain" of the cell, which controls all functions within the cell.
What is the nucleus?
300
The three groups of vascular plants are:
Flowering plants, cone-bearing plants, and ferns.
300
This group of vertebrates are cold blooded, lay their eggs in the water, begin their lives in water but may move onto land after growing legs, and have smooth skin.
What are amphibians?
300
This is the largest group of invertebrates. These creatures have exoskeletons and jointed legs. This group includes insects, crustaceans, and arachnids.
What are arthropods?
400
Name the five kingdoms into which living organisms are grouped.
Plants, animals, fungi, bacteria, and protists
400
The jelly-like liquid inside a cell, in which the parts of the cell "float".
What is cytoplasm?
400
The three groups of nonvascular plants, or bryophytes, are called:
Mosses, hornworts, and liverworts.
400
This group of vertebrates are cold blooded, lay their eggs on land, and have scales covering their bodies.
What are reptiles?
400
These invertebrates have a brain and a system of nerves. They have five hearts that pump blood to all their parts.
What are worms?
500
These are the two types of protists.
What are algae and protozoans?
500
The parts of plant cells in which photosynthesis takes place. Animal cells do not have these.
What are chloroplasts?
500
Bryophytes do not have this part, which other plants have, since they do not get their water from the soil.
What are roots?
500
This group of vertebrates are warm blooded, give birth to live young, and feed their babies milk. They have hair on their bodies.
What are mammals?
500
Corals, jellyfish, and sea anemones are members of this group of invertebrates.
