Metamorphosis and Fossil Record Test

Woody plants have many different kinds of leaves. Some leaves have very smooth edges, while other leaves have jagged edges, as shown in the diagram. The characteristics of plant leaves vary with the climate in which the plant naturally grows. Some scientists discovered an area with many fossilized leaves of woody plants. The scientists used data from samples of 100 leaf fossils to compare the number with smooth-edged leaves and the the number with jagged edge leaves. The scientists concluded that the plants plants had grown in a hot climate. Which graph most likely represents the data from the investigation?

The life cycle of a flowering plant starts again when a mature plant produces --

• leaves

• roots

• seeds

• petals

Based on the diagram, which statement best compares the life cycles of these two types of organisms?

• Young ladybird beetles take many years to develop into adults. Young grasshoppers develop into adults quickly

• Young grasshoppers live in a habitat that is different from that of adults. Young ladybird beetles live in the same habitat as adults

• Young grasshoppers undergo incomplete metamorphosis to become adults. Young ladybird beetles undergo complete metamorphosis to become adults.

• Young ladybird beetles have nymph stage before becoming adults. Young grasshoppers are larvae before becoming adults.

The diagrams below represent the life cycle of four different insects. Which of these insects goes through a complete metamorph?osis

• F

• G

• H

• J

The life cycles of buttfly and a chigger are shown below.

How is the life cycle of chiggers different from the life cycle of butterflies?

• Chiggers larvae have legs

• Chiggers have a nymph phase

• Chiggers go through metamorphosis

• Chigger larvae hatch from eggs.

Which observation best supports the conclusion that this insect undergoes incomplete metamorphosis?

• The insect changes color when it becomes an adult

• The first stage of the insect's development is an egg

• The insect undergoes more than four stages in the development

• the insect has similar body parts throughout its development

How are adult animals and adult plants the same? Both adult animals and adult plants

• can make their own food

• have alarva stage

• can produce offsping

• have at least two legs

• 3,4,2,1

• 2,3,1,4

• 1,2,3,4

• 3,1,2,4
