3 Answer the questions using the cell images shown below. DE1. What type of cell is shown in the pictures above?2. Which cell is in the first phase of cell division?3. Which cell is in anaphase?4. What stage is shown in cell A?5. Which stage is shown in cell B?6. List the cells in the order they occur in cell division.Plant cellECProphaseTelophaseEADCB
4 Identify the type of asexual reproduction and support your answer. Vegetative propagationBuddingRegenerationVegetative propagation
5 A B C Amniotic fluid Umbilical cord Identify the type of development occurring in this picture.Identify the types of organisms that use this type of development.Identify the labeled structures.ABAmniotic fluidCUmbilical cord
6 Identify the structures labeled. Identify the process that occurs in structure E.Describe the path of sperm throughout the male reproductive tract.Describe the importance of structure F.
7 Identify the structures labeled. Identify the process that occurs in structure E.MeiosisA – urinary bladderB - urethraC - penisD – vas deferensE - testesF - scrotum
8 3. Describe the path of sperm throughout the male reproductive tract. Testes Vas deferens Urethra4. 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.
9 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
10 Identify the type of development observed in the diagram. Identify the types of organisms that use this type of development.Identify the source of nutrition for the embryo.Identify what cushions and protects the embryo.External developmentAquatic and terrestrialYolkAmniotic fluid
11 B - ovary D - uterus A - oviduct D - uterus Ovulation Meiosis Identify the structure that produces estrogen and progesterone.Where does a zygote develop?Where is the egg fertilized?Where does the placenta form?Identify the process when an egg is released from an ovary.Identify the process that occurs in the ovaries.B - ovaryD - uterusA - oviductD - uterusOvulationMeiosis
43 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 environment3. Identify structure A.4. Identify the two substances produced by structure A.5. Identify the process occurs in structure A.A
44 Which the structure in which internal fertilization usually occurs? (1.) allantois (2.) oviduct (3.) gonad (4.) uterus2. In which structure is a developing embryo implanted?(1.) oviduct (2.) uterus(3.) ovary (4.) vagina3. Which structure makes nutrients and oxygen directly available to the embryo?(1.) uterus (2.) oviduct(3.) placenta (4.) ovary
45 Identify each labeled structure in the diagram. Identify the structure where the fetus develops.Identify the structure where meiosis occurs.Identify the structure where fertilization occurs.
46 1. Which process is represented by the arrows in the diagram? (1) meiosis (3) mitosis (2) fertilization (4) evolution2. Identify another name for this process.3. Describe what occurs to the cells produced in this process.3. Identify the result of this process.
47 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.
48 What is the primary function of this egg? food supply for predators to preserve predator populationsadaptation to allow maximum freedom for parent birdscontinuation of the species through reproductionpreservation of the exact genetic code of the parent birds
49 An adaptation for reproduction in most terrestrial organisms is vegetative propagationinternal fertilizationregenerationmitosis
50 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?
51 Which represents binary fission? Support your answer.
52 External fertilization occurs most often in mammals and birdsreptiles and birdsamphibians and reptilesfish and amphibians
53 Identify the process represented in the diagram. Where does this occur?Describe what happens to the chromosome number.Compare the daughter cells to each other.
54 The blockages shown at A and B would most likely interfere with the ability to transport gametesproduce mature gameteseliminate waste products through the urethraexpress secondary sex characteristics
56 The process in which insect species change their body shape form and become adults is known as mitosismetamorphosismeiosiscleavage
57 Metamorphosis in which larva develop inside pupa is known as incomplete metamorphosistransitional metamorphosisembryonic metamorphosiscomplete metamorphosis
58 The part of the pistil which contains the pollen tube is the __________. The transfer of pollen between the anther and the stigma in any flowering plant or plants is called _____.In order to reach an ovule, a ______ must grow through the style.The sex cells in a flowering plant are located in the ____.The egg cell of a flowering plant develops in the _____.
