Sexual And Asexual Reproduction Study Guide

Sexual and Asexual Reproduction Study Guide
 
I can compare sexual and asexual reproduction.


Sexual Reproduction
 
1. Requires 2 parents.
2. The joining of egg and sperm is called fertilization.
3. Sexual reproduction requires each parent to contribute 23  chromosomes
   each.
4. The joining of egg and sperm creates a zygote.
5. Sexual reproduction requires the union of egg  and sperm.
6. A zygote is a cell that has 46 chromosomes.
7. Sexual reproduction creates variations in the offspring.
8. How are variations beneficial?
 
 They can help a species survive if a disease breaks out. It can help them adapt to changes in their environment.
 
9. Sexual reproduction requires a long gestation period.
10. Sexual reproduction can cause deformities in the offspring.
11. TRUE or FALSE: Sexual reproduction is 100% successful.
12. Asexual reproduction requires 1 parent(s).
13. Offspring produced through asexual reproduction are identical
     in appearance.
14. An example of tubers that reproduce asexually is _potatoes.
15. This type of asexual reproduction produces an identical copy of single celled organisms. binary fission.
16. Strawberry plants reproduce asexually by producing new plants from runners.
17. A hydra reproduces asexually through a process called budding.
18. Onions reproduce asexually by producing bulbs.
19. Bacteria cells reproduce asexually through a process called binary fission.
20. Identify three advantages of asexual reproduction.
       A. no gestation period
       B. no mate needed
       C. 100% successful
21. The length of time from conception to birth is called gestation period
22. The main disadvantage to asexual reproduction is no variations.
 
 
I can explain how flowers reproduce
Sexually and Asexually.
 
1. Study your flower parts and function page.
2. Use your flow chart to be able to track pollen from the anther to the ovules. Know how seeds are produced.
3. The part of a fruit that we eat is the ovary of the flower.
4. In order for a fruit to be classified as a fruit it must contain seeds.
5. The purpose of the petals is to attract pollinators.
6. Organisms that carry pollen from flower to flower are called pollinator.
7. Fertilized ovules produce seeds in flower plant.
8. Flowering plants that produce fruit containing seeds are called angiosperm
9. Pollinators are wind, water, bees, small mammals, birds.
10. How does the fruit help the seeds inside? suplies protection and a place to house them 
11. The production of seeds is created by sexual reproduction.
12. Male reproductive structure _stamen.
     Female reproductive structure pistil.
     _anther produces pollen.
