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.
