Chapter 3 Review
Science
Traits offspring are given from their
parents.
• Inherit
A feature or characteristic of a living
thing.
• Traits
The process in which some organisms
change form in different stages of its
life cycle.
• Metamorphosis
For most animals this is the first stage
in its life cycle
• egg
The length of time it takes a living
organism to complete its life cycle.
• Life span
A series of stages that occur during the
lifetime of a living thing.
• Life cycle
What the seeds do once it reaches a
place that is can grow.
• Germinate
Plant or animal at its earliest stage of
development.
• Embryo
Stage 1 of the Bug Life Cycle
Stage 2 of the Bug Life Cycle
Stage 3 of the Bug Life Cycle
Stage 4 of the Bug Life Cycle
Explain the stages in the life cycle of a
flowering plant.
• Pollen moves from stamen to the
pistil where seeds are produced.
The seeds are released. When
they germinate, new plants grow.
Give two examples of traits humans
inherit.
• Traits may include physical features such as:
– Eye color
– Hair color
– Nose shape
– Mouth shape
Do all plants have the same life span?
Explain your answer.
• The length of time it takes a plant to complete
its life span varies. Some plants only live for
one year, like bean plants. Other plants live for
hundreds of years, like a maple tree.
Describe one way that the life cycles of
mammals and insects differ.
• Insects hatch from eggs, mammals are born
alive.
