what are the different ways that plants reproduce?
they can reproduce from spores or seeds
100
vertebrate
an animal with a backbone
100
what two characteristics might scientists consider when classifying animals?
how the animal moves, what it eats, where it lives
200
species
a group of similar organisms that can mate and produce offspring that can also produce offspring
200
what is the general, and therefore the largest, classification group called?
domain
200
dichotomous key
a tool used to identify organisms
200
How does a dichotomous key work?
through a series of questions that include characteristics of organisms, a specific plant, animal, fungus, or protist can be classified
200
kingdom
the level of classification of living things below domain
300
what are three types of invertebrates?
mollusks, worms, and arthropods
300
what features make animals different from other organisms?
they are multicellular, eat other organisms in order to get energy, and move about during part or all of their lives
300
vascular
a type of plant with tubes that carry food and water to all parts of the plant
300
what are two main characteristics for classifying plants?
plants are classified according to whether or not they have vascular tissue, and according to how they reproduce
300
explain why scientists use classification system to organize living things.
a classification system helps scientists know characteristics about organisms based on how they are classified
400
why are plants and fungi classified in different kingdoms when they have some similar characteristics?
although plants and fungi both live on land and are made of many cells, plants make their own food using the sun's energy, while fungi get their food from other living and nonliving things
400
what are some questions you would ask to classify an animal?
does the animal have a spine? what is its body like on the inside and outside? does it live on land or in water? does it lay eggs or give birth to live young?
400
how is being vascular an advantage to a plant?
tubes allow food and water to travel to all parts of the plant. the tubes strengthen and support a plant
400
a type of vascular plant that reproduces using cones and seeds
seeds
400
an animal has scales and is cold-blooded. it lives in the water. what other information do you need to know before you can classify it?
whether it uses lungs or gills, whether its eggs have shells or not
500
what mnemonic device can you make to help remember the eight levels of classification?
domain, kingdom, phylum, class, order, family, genus, species

what are the four kingdoms of Eukarya?
Eukarya's four kingdoms are protists, fungi, plans, and animals
500
what advantage does a vascular plant have over a nonvascular plant?
because they have tubes that carry water to all parts of the plant, vascular plants are not limited to areas near water
500
how are flowering plants alike? how are they different?
they are both vascular. many conifers have needles and reproduce using cones and seeds. flowering plants have flowers that make seeds
500
how would you classify a plant that is vascular, has leaves, but does not have seeds?
