What cellular division process is used in asexual reproduction? 
Mitosis
100
Define sexual reproduction. 
The production of a new organism from two parents. 
100
What type of reproduction do plants do? 
Both sexual and asexual
100
Put these steps in the correct order that would result in the formation and development of an embryo: mitosis, meiosis, fertilization 
meiosis (produce sperm and egg) 

fertilization (meeting of sperm and egg to produce zygote)

mitosis (dividing of initial zygote cells to grow and develop into a fetus with specialized cells)

100
What is most commonly produced by mitosis in humans? 
Skin cells
200
What is a major disadvantage of asexual reproduction? 
No genetic variation
200
What is a major advantage of sexual reproduction? 
Large amount of genetic variation between parent and offspring
200
If a piece of a stem is taken from a red flowering plant and is placed in soil and turns into a new plant, what will the new plant look like? 
A red flowering plant identical to the parent plant because it is asexual reproduction
200
How many chromosomes are found in a human gamete compared to a human embryo cell? 
Half, 23. 
200
What type of fertilization do most fish and amphibians use?
External fertilization in the water. 
300
What is it called when pieces of a plant are used to create a new plant? Give one specific example. 
Vegetative propagation. 

Ex: budding

300
What cell process occurs only in organisms that produce sexually? 
meiosis
300
What are the male and female reproductive structures in a flower? 
Male- stamen

Female-pistil

300
What structure connects the human embryo to the placenta? 
Umbilical cord
300
What type of fertilization and development occurs in the life cycle of fish? 
External fertilization and external development
400
Are cells produced by mitosis haploid or diploid? 
Diploid- same number of pairs of chromosomes as the parent cell
400

What is a characteristic of sexual reproduction that favors the survival of land dwelling animals? 

Internal fertilization in the female body
400
What are the female and male gametes called in a flower? 
Male- pollen

Female- ovules (eggs)

400
Why do males produce such a large amount of sperm cells, when females only produce a few egg cells? 
This increases the chance that one of the sperm cells will survive and reach the egg to fertilize it
400
What is the process by which chromosomes exchange some pieces of DNA called? 
Crossing over
500
What are the three primary purposes of mitosis? 
Growth of an organism

Tissue repair in an organism

Asexual reproduction

500
What is the reproductive cycle of most birds and reptiles? 
Internal fertilization and external development. 
500
What are two ways pollen can reach the ovary of a flower for fertilization to occur? 
Wind carries the pollen to other flowers

Insects pollinate by carrying pollen on feet/legs between flowers 


500
What processes normally occur at the placenta?  (3 different things)
Oxygen and nutrients diffuse from the mother to the fetus. Waste diffuses from the fetus to the mother. No blood is transferred. 
500
What are two differences between mitosis and meiosis? 
Mitosis: one parent cell= two daughter cells, growth and repair, daughter cells genetically identical to parent cell

Meiosis: one parent cell=4 daughter cells, gamete production, daughter cells genetically vary from each other and from parent cell
