1. Identify the type of development occurring in this picture.2. Identify the types of organisms that use this type of development. 3. Identify the labeled structures.
1. Identify the structures labeled.
2. Identify the process that occurs in structure E.
3. Describe the path of sperm throughout the male reproductive tract.
4. Describe the importance of structure F.
1. Identify the structures labeled.
2. Identify the process that occurs in structure E.
Meiosis
A – urinary bladderB - urethraC - penisD – vas deferensE - testesF - scrotum
3. Describe the path of sperm throughout the male reproductive tract.
Testes Vas deferens Urethra
4. Describe the importance of structure F.The scrotum keeps the testes 2° to 4° cooler than the rest of the body.
The cooler temperature is needed for optimum sperm production.
Topic: ReproductionAim: Describe the developmental patterns of
insects.
Do Now: Sit next to your 3 o’clock partner to work on reproduction review questions.
HW: Seeds Close Reading ISN
1. Identify the type of development observed in the diagram.
2. Identify the types of organisms that use this type of development.
3. Identify the source of nutrition for the embryo.
4. Identify what cushions and protects the embryo.
External development
Aquatic and terrestrial
Yolk
Amniotic fluid
1. Identify the structure that produces estrogen and progesterone.
2. Where does a zygote develop?
3. Where is the egg fertilized?
4. Where does the placenta form?
5. Identify the process when an egg is released from an ovary.
6. Identify the process that occurs in the ovaries.
B - ovaryD - uterus
A - oviduct
D - uterus
Ovulation
Meiosis
1. Identify the process in which insects shed their skin in order to grow.
• Molting
2. Where is the new exoskeleton produced?
• Under the existing exoskelelton
3. When does molting stop?
• When insect reaches its adult stage
4. Identify the process in which the body structure of an insect changes.
• Metamorphosis
5. Identify the two types of metamorphosis.
• Incomplete metamorphosis• Complete metamorphosis
6. List the stages of incomplete metamorphosis.
• Egg nymph adult
7. Describe what a nymph resembles.
• A miniature adult without wings
8. What occurs before a nymph develops into an adult?
• Each molt produces a larger, more mature nymph
9. Identify 5 insects that develop that have incomplete metamorphosis.
• Grasshoppers• Roaches• True bugs• Dragonflies• Praying mantises
10. List the stages of complete metamorphosis.
• Egg larva pupa adult
11. Describe what larva resembles.
• Worms• Do not look like adults
12. Identify 2 other names for larva.
• Grubs• Maggots
13. Why are larva classified as insects?
• They have 6 legs and simple eyes.
14. What do larva do during their lifetime?
• Eat, grow and store fat
15. How does a larva develop into a pupa?
• Molts one last time
16. Identify the structure that encases the pupa.
• Chrysalis or cocoon
17. Describe what occurs to the pupa while encased in that
structure.
• Internal structures of larva melt down and are reassembled into new structures.
18. Identify an example of structures that could develop inside the chrysalis.
• Wings
19. How does the pupa develop into an adult?
• Pupa splits and final molt reveals the adult
20. Identify 5 insects that develop that have complete
metamorphosis.
• Fly, beetle, mosquito, butterfly, moth
1. Identify structure X.2. An obstruction in X would
directly interfere with the (1) transfer of sperm to a
female(2) production of sperm(3) production of urine(4) transfer of urine to the external environment
3. Identify structure A.4. Identify the two substances
produced by structure A.5. Identify the process occurs
in structure A.A
1. Which the structure in which internal fertilization usually occurs? (1.) allantois (2.) oviduct (3.) gonad (4.) uterus
2. In which structure is a developing embryo implanted? (1.) oviduct (2.) uterus (3.) ovary (4.) vagina
3. Which structure makes nutrients and oxygen directly available to the embryo? (1.) uterus (2.) oviduct (3.) placenta (4.) ovary
1.Identify each labeled structure in the diagram.
2.Identify the structure where the fetus develops.
3. Identify the structure where meiosis occurs.
4.Identify the structure where fertilization occurs.
1. Which process is represented by the arrows in the diagram?(1) meiosis (3) mitosis(2) fertilization (4) evolution
2. Identify another name for this process.3. Describe what occurs to the cells produced in this
process. 3. Identify the result of this process.
1. Identify the type of fertilization and development used to produce this egg.
2. Identify the source of food for this embryo.
3. Identify the structure that protects this embryo.
What is the primary function of this egg?1.food supply for predators to preserve predator populations2.adaptation to allow maximum freedom for parent birds3.continuation of the species through reproduction4.preservation of the exact genetic code of the parent birds
An adaptation for reproduction in most terrestrial organisms is
(1) vegetative propagation
(2) internal fertilization
(3) regeneration
(4) mitosis
The diagram below represents chromosomes in a zygote.
Which diagrams best illustrate the daughter cells that result from normal MITOTIC cell division of this zygote?
Which represents binary fission? Support your answer.
External fertilization occurs most often in
1.mammals and birds2.reptiles and birds3.amphibians and reptiles4.fish and amphibians
1.Identify the process represented in the diagram.
2.Where does this occur?
3.Describe what happens to the chromosome number.
4.Compare the daughter cells to each other.
The blockages shown at A and B would most likely interfere with the ability to1.transport gametes 2.produce mature gametes3.eliminate waste products through the urethra 4.express secondary sex characteristics
