pg. 19 Asexual vs. Sexual Reproduction

On the side of

the page, write in big print

“ Asexual vs. Sexual Reproduction”.

Cut out the entire chart and glue it in sideways.

Use the info below to fill in the chart.

Write the following on the

Asexual

side:

Definition

: Creating

a new organism from a

single

parent

Product

: Produces

offspring that are

genetically identical

to the

parent.

Examples

: Fragmentation, Regeneration, Parthenogenesis, Budding,

Gemmules

Advantages

: Able to reproduce rapidly, does not require a mate to

reproduce (wont take a lot of time and energy)

Disadvantages

: No genetic diversity, the offspring inherit

any

mutations of the

parent, can’t survive in constantly changing environments

Write following on the

Sexual

side:

Definition

: Creating

a new organism from 2 different parents (Male and Female)

Fertilization

:

sperm meet egg, Internal= inside the female’s body, external= outside the body

Product

: 2

haploid

gametes fuse to create a

diploid

zygote

Advantages

: Diversity in offspring, Offspring less likely to have mutations show

up, more likely to survive in changing environments

Disadvantage

: Requires a

mate,

Population increases are

limited, leads to deadly competition, reproductive behaviors can attract predators

pg. 20 Animal Development

At the top of

the page, write in big print

“ Animal Development”.

You will receive 2 handouts. Cut out the entire box on each handout.

Animal Development 1 goes on the front of pg. 20 and Animal Development 2 goes on the back of pg. 20.

Use your notes (pg. 4-5) to fill out the stages on Animal Development 1 for #1-6.

Ex. #1. Zygote-fertilized egg

#2- Cleavage- zygote divides into 2 cells

#3- Blastomere-4 cells, cleavage continues

Write OMIT for #7

Use your flashcards for #8

pg. 20 Animal Development- Back

Use your notes (pg. 4-5) to fill out the stages on Animal Development 2 for #1-9.

Ex.

#1. Blastula

#2- Blastocoel

#3- The cells are moving inward towards the middle

#10. Process of the blastula cells beginning to move inward to form a gastrula

#11. It disappears as the cells continue to move inward.

pg. 21 3 Germ Layers

At the top of

the page, write in big print

“ 3 Germ Layers”.

You will receive 1 handout. Cut out the entire box on the handout. Glue it down on pg. 21.

Use your Notes (pg.5) or Flashcards to answer #1-5.

Ex. #1. Layers of cells that give rise to specialized structures in the developing embryo

#6. Animal with radial symmetry (

Porifera

and

Cnidaria

)

#7. They will NEVER develop complex organs

pg. 22 Embryo Development

At the top of

the page, write in big print

“ Embryo Development”.

You will receive 2 handouts. Cut out the entire box on each handout.

Embryo Development 1 goes on the front of pg. 22 and Embryo Development 2 goes on the back of pg. 22.

Use your notes (pg. 7) and the drawing below to fill out the stages on Embryo Development 1 for #1-16

Ex. #1. Ectoderm

#2- Endoderm

#3- Mesoderm#4- coelom#17- Mollusca, Annelida, and Arthropoda#18- Coelom made from the splitting of the mesoderm

pg. 22 Embryo Development-Back

Use your notes (pg. 7) and the drawing below to fill out the stages on Embryo Development 1 for #1-16

Ex. #1. Blastopore

#2- Ectoderm

#3- Endoderm

#4- Archenteron

#17- Echinodermata

and

Chordata#18- Coelom created from pockets made by mesoderm

pg. 23 Protostomes vs. Deuterostomes

At the top of

the page, write in big print

“ Protostomes vs.

Deutrerostomes

”.

You will receive 1 handout. Cut out the entire box on the handout. Glue it down on pg. 23.

Use your notes (pg. 6 and 7) to answer the type of cleavage and fate of blastopore for both.

For Protostomes:

Coelom Formation: The mesoderm takes shape between the endoderm and ectoderm. The coelom arises from the splitting of the mesoderm. Phyla: Mollusca, Annelida, and Arthropoda For Deuterostomes:Coelom Formation: The mesoderm comes from out pocketing, t

hese pockets will become the coelom.

Phyla:

Echinodermata and

Chordata

At the top of

the page, write in big print

“

.

You will receive 1 handout. Cut out the entire box on the handout. Glue it down on pg.
