Vascular and Nonvascular Plants
Inherited Traits
5 types of Vertebrates
Mammals
Birds
Reptiles
Fish
Amphibians
 Have hair or fur , produce milk for their young, warm-
blooded, breathe with lungs
 Examples: Whales, bears, cats, dogs, and humans
 Lay eggs, have wings, warm blooded, feather cover
their skin, most fly, breathe with lungs
 Cold blooded, scales or plates on their skin, lay eggs on
land, have lungs for breathing air
 Examples: snakes lizards, alligators, turtles, and
crocodiles.
crocodiles.
 Live in the water, Cold-blooded, breathe with gills,
scaly skin, lay eggs
 Examples: tuna, trout, carp, and catfish.
 Cold-blooded, Spend part of their lives on land and
part in the water, young amphibians live underwater
with gills, and as adults they live on land and develop
lungs, have smooth, moist skin, lay eggs.
 Examples: frogs, toads, newts, and salamanders
 They have tubes that carry water and
nutrients from the roots to the leaves.
 They have veins
 They are usually tall
 Trees, grasses, and most garden plants
are all vascular.
Angiosperm
Gymnosperm
 Angiosperms have

sponges.
They don’t have tubes
They don’t have stems
They don’t have true roots
They don’t have leaves, just leaf-like
structures
They are smaller than vascular plants (They
are low to the ground, so that most of the
plant touches soil to absorb water.)
Inherited Traits
 Genes passed from your
parents to their offspring
½ from mother, ½ from
father.
 Dominate gene or
recessive gene
 Both physical features
and behaviors are
inherited.
 Physical Ex: puppy
inherits 4 legs
 Behavior Ex: rolling of
the tongue.
Learned Behavior
 A skill that an animal
develops after it is born.
 Genes do not control
learned behavior.
 Humans and Animals
learn from adults and
experiences.
*Ability to roll your
tongue or not
* Attached or
unattached earlobes
* Dimples or freckles
* Naturally curly or
straight hair
* Hitchhiker’s or
straight thumb
*Color-blindness or
normal color vision
* Widow’s peak or
straight hairline
* Color of skin and hair
* Cleft or smooth chin
A mother bear may show her cubs how to fish or
find berries for food.
A bird may teach its babies how to fly.
A young horse may learn to stay away from an
electric fence after the horse gets shocked.
A pet can learn that food appears in its bowl after
it hears the sound of a can opener or a bag rattle.
Young chimpanzees learn from adults to use sticks
as tools for getting food.
You were born knowing how to use your voice, but
you were not born knowing how to speak a
language.
