Reproduction

Question 0

Sexual reproduction

Answer 0

When an organism combines their DNA with another organism of the same species to form genetically unique and different offspring

Question 1

Asexual reproduction

Answer 1

When an organism copies its own DNA to produce genetically identical offspring

Question 2

The genetic material found in the nucleus of all living cells (eukaryotic); contains the information needed for

Answer 2

An organism to grow, maintain itself, and reproduce

Question 3

When an organism reproduces it passes it’s

Answer 3

Genetic information

Question 4

A new organism is produces from one organism in

Answer 4

Asexual reproduction

Question 5

Uniform offspring

Answer 5

Offspring from asexual reproduction are identical to the parent

Question 6

Types of asexual reproduction

Answer 6

Binary fission
Budding
Regeneration
Vegetative propagation

Question 7

Binary fission

Answer 7

One organism divided into 2 organisms

Ex. Bacteria, algae

Question 8

Budding

Answer 8

New organism grows from the surface of the body of the parent
Ex. Yeast, paramecia

Question 9

Regeneration

Answer 9

New organism grows from pieces of the parent

Ex. Planaria (flatworm), starfish

Question 10

Vegetative propagation

Answer 10

New cells separate from the parent and form a completely new individual
Ex. Plant cuttings, potato

Question 11

Requires 2 organisms to produce offspring

Answer 11

Sexual reproduction

Question 12

Diverse offspring

Answer 12

Offspring from sexual reproduction share characteristics of both parents

Question 13

Fertilization

Answer 13

Joining of egg and sperm cell

Question 14

Zygote

Answer 14

New cell formed by fertilization

Question 15

Egg+sperm=

Answer 15

Zygote

Question 16

Advantages to sexual reproduction

Answer 16

-species can adapt to their environment because there is more diversity in their gene pool

Question 17

Advantages to asexual reproduction

Answer 17

• organisms do not need to look for mates

- can produce numerous offspring without much energy

Question 18

Disadvantages to sexual reproduction

Answer 18

• requires more energy
• takes more time
• fewer offspring

Question 19

Disadvantages to asexual reproduction

Answer 19

-lack of variation in the gene pool makes it harder to adapt, must rely on mutations

Question 20

Cladogram

Answer 20

Shows the relationship of species within a kingdom and adaptations that set them apart

Question 21

Spores

Answer 21

Haploid reproduction cells

Question 22

Spores form by

Answer 22

Meiosis in the sporophyte plant (2n)

Question 23

Gametes

Answer 23

Specialized cells involved in sexual reproduction; sperm and egg

Question 24

Gametes form by

Answer 24

Mitosis in the game phage plate (n)

Question 25

All plants are characterized by

Answer 25

Alteration of generations

Question 26

Female gamete

Answer 26

Egg/ovum

Question 27

Male gamete

Answer 27

Sperm

Question 28

During puberty the hypothalamus

Answer 28

Sends signals to the pituitary to develop sexual reproduction

Question 29

The pituitary sends out:

Answer 29

FSH-triggers sperm production in males | LH-sends out androgens like testosterone

Question 30

Androgens

Answer 30

(Testosterone, progesterone, estrogen) | Trigger development of sexual characteristics

Question 31

Epicotyl

Answer 31

Embryonic leaves

Radicle

Answer 34

First root

Question 35

Hilum

Answer 35

Mark on the seed where it was attached to the ovary, sometimes called the 'eye'

Question 36

Embryology

Answer 36

Development of the embryo after fertilization

Question 37

Germ layers

Answer 37

Group of cells formed after embryo development

Question 38

Ectoderm

Answer 38

Outer coverings of an organism

Question 39

Endoderm

Answer 39

Digestive system and other internal organs like lungs

Question 40

Mesoderm

Answer 40

Muscles, much of circulatory, reproductive and excretory organ systems

Question 41

Germ line cells

Answer 41

Diploid cells in ovaries and testes that undergo meiosis to produce gametes

Question 42

Somatic cells

Answer 42

Diploid cells in the body (other than neurons) that undergo mitosis to produce more of themselves
