1. The diagrams in the first column of the chart below show various forms of reproduction. In the second
column, circle the form of reproduction (asexual or sexual) shown by each of the diagrams. [2]
2. ______ The male sex cell is the
1 egg
2 sperm
3 ovary
4 testes
3. Base your answers to the three following questions on the diagram below and on your knowledge of science.
The diagram shows the result of sexual reproduction.
Identify the two sex cells that are necessary for sexual reproduction. [1]
1.
___________________________________________________
2.
___________________________________________________
In each of the offspring, what percentage of the genetic material comes
from the male parent? [1]
_______________ %
State one advantage that a species that reproduces sexually has over a species that reproduces asexually. [1]
4. Base your answers to the following questions on the diagram below and on your knowledge of science. The
diagram shows a model of sexual reproduction. The lines in each cell represent genetic material
(chromosomes).
Which letter in the diagram represents a female sex cell? [1] _______
Which process is occurring at C? [1] ____________________________
What evidence in the diagram shows that sexual reproduction occurred? [1]
______________________________________________________________
5. Base your answers to the following three questions on the diagram below which shows the process of sexual
reproduction.
Identify the sex cell shown at A. [1] _________________________
Identify the sex cell shown at B. [1] _________________________
Identify the reproductive process that is occurring at C. [1] ________________________
6. _________ Which example would result in new cells that are most different from the parent cells?
(1) yeast cells splitting into new cells
(2) bacteria cells dividing into new cells
(3) skin cells dividing to produce more skin cells
(4) sperm and egg cells uniting to produce fertilized egg cells
7. ________ In humans, a fertilized egg contains 46 chromosomes. Which bar graph best represents the number
of chromosomes contained in the sperm and egg before they united
to make the fertilized egg?
8. Base your answers to the two following questions on the diagram below and on your knowledge of science.
The diagram shows four stages in the development of a human after fertilization.
_______ Between stages A and D, which process must occur?
(1) mutation
(3) cell division
(2) sexual reproduction
(4) extinction
_______ Which sequence of development is correct?
(1) fertilized egg tissues organ systems organs
(2) fertilized egg organ systems organs tissues
(3) fertilized egg organs tissues organ systems
(4) fertilized egg tissues organs organ systems
9. _______ When do organs begin to develop in humans?
(1) in the sperm cell before fertilization
(2) before fertilization and after birth
(3) in the egg cell after fertilization
(4) after fertilization and before birth
10. The diagram below shows how a frog develops. A fertilized egg hatches into a tadpole with gills. The
tadpole develops legs and lungs and becomes an adult frog.
_______ What is the term for this series of changes during the life cycle of the frog?
(1) fertilization
(3) mutation
(2) reproduction
(4) metamorphosis
11. _______ Young frogs do not resemble adult frogs. Which term is given to this pattern of development in
frogs?
(1) asexual reproduction
(3) metamorphosis
(2) cloning
(4) biological adaptation
12. _______ Which process is illustrated in the diagram below?
1 natural selection
2 mutation
3 metamorphosis
4 photosynthesis
13. The diagram below shows the development of a certain type of insect.
_______ This diagram shows the process of
(1) metamorphosis
(3) selective breeding
(2) fertilization
(4) environmental change
14. The diagrams below show the life cycles of a grasshopper and a butterfly.
Describe one difference in the pattern of development of the grasshopper and the pattern of development of the
butterfly shown in the diagrams. [1]
15. _______Which process is directly responsible for root growth in plants?
(1) storage
(3) transportation
(2) absorption
(4) cell division
16. _______ Naturally occurring variations within a species are mainly the result of mutations and
(1) sexual reproduction
(3) metabolism
(2) dynamic equilibrium
(4) camouflage
17. _______During which process does a caterpillar become a butterfly?
(1) fertilization
(3) asexual reproduction
(2) metamorphosis
(4) biological adaptation
The hydra shown below is reproducing asexually.
18. _______What percentage of the offspring’s genetic information is the same as the genetic information of the
parent?
(1) 25%
(3) 75%
(2) 50%
(4) 100%
Base your answers to the questions below on the chart below and on your knowledge of science. The chart
describes typical fertilization and development in three different animals.
19. Which animals in the chart undergo internal fertilization? [1]
________________________________ and ________________________________
20. Which animals in the chart develop externally? [1]
________________________________ and ________________________________
21. Why do human egg and sperm cells have only 23 chromosomes when human body cells have 46
chromosomes? [1]
