Lab #7 Reproductive system

Question 1

What is mitosis

Answer 1

When a somatic cell replicates and produces another 2n cell

Question 2

What is meiosis

Answer 2

when sex cells replicate and produce a 1n cell

Question 3

During prophase 1 what is happening to the chromosomes centrioles spindle fibers

Answer 3

The chromosomes have started to condense but are still scattered around the cell centrioles are migrating to opposite poles and the spindle fibers begin to form

Question 4

During metaphase 1 what is happening to the chromosomes spindle fibers

Answer 4

tetrads have aligned along the metaphase plate spindle fibers are formed and attached to centromeres

Question 5

During anaphase 1 what is happening to the chromosomes spindle fibers

Answer 5

full chromosomes separate and move to opposite ends of the cell when they reach the opposite pole anaphase is complete

Question 6

What is the epididymis and what happens inside of it

Answer 6

the thing that sits on top of the testis and is where sperm mature and is stored

Question 7

What is the Ductus deferens

Answer 7

Also known as the vas deferens and carries the sperm from the testes to the urethra

Question 8

What is another name for the uterine tube

Answer 8

The fallopian tube

Question 9

Where is the Primordial OF Primary OF Secondary OF Tertiary OF corpus luteum corpus albicans

Answer 9

Question 10

How could you identify a primary ovarian follicle

Answer 10

A single layer of cuboidal cells surround the ovarian follicle

Question 11

How could you identify a secondary ovarian follicle

Answer 11

Stratified layer of cuboidal cells surrounds the ovarian follicle

Question 12

How could you identify a tertiary follicle

Answer 12

There is an antrum (the big fluid filled space)

Question 13

Answer 13

Thick white capsule that covers the outside of the testis

Question 14

What do the interstitial endocrine cells do in the testies

Answer 14

Produce testosterone

Question 15

What are the 4 stages of spermatogenesis

Answer 15

Spermatogonia
Primary spermatocyte
Secondary spermatocyte
Spermatids

Question 16

Do spermatogonia divide by mitosis or meiosis

Answer 16

Mitosis

Question 17

Which cell during spermatogenesis undergoes meiosis

Answer 17

Primary spermatocyte

Question 18

Label the Spermatogonia Primary spermatocyte secondary spermatocyte spermatids

Answer 18

Question 19

What do sustenocytes do and where are they located

Answer 19

they provide nourishment for the spermatids and attach to the basement membrane of the seminiferous tubules

Question 20

What is a pronucleus

Answer 20

The nucleus of the male or female reproductive cell

Question 21

What is a zygote

Answer 21

A single diploid cell created from the two male and female sex cells

Question 22

What is the difference between the maturation of the female and male sex cells

Answer 22

Spermatogenesis creates 4 viable sperm whereas oogenesis creates only one viable ovum and 2 or 3 polar bodies
