Fragmentation
Parthenogenesis

Question 5

It is the fusion of haploid gametes to form a diploid cell, the zygote

Answer 5

Sexual Reproduction

Question 6

For most asexual animals, reproduction relies entirely on ________.

Answer 6

mitotic cell division

Question 7

The animal that develops from a zygote can in turn give rise to gametes by ______.

Answer 7

meiosis

Question 8

Most animals exhibit cycles in reproductive activity, often related to _________. These cycles are controlled by _______, whose secretion in turn is regulated by __________.

Answer 8

changing seasons, hormones, environmental cues

Question 9

both the male and female gametes are produced by the same individual. Examples are Tunicates and Earthworms.

Answer 9

Hermaphroditic/Monoecious

Question 10

having male reproductive organs in one individual and female in another

Answer 10

Dioecious

Question 11

The production of gametes, sperm and egg cells, and takes place through the process of ______

Answer 11

meiosis

Question 12

Each type of gamete have its own process of reproduction, namely;

Answer 12

spermatogenesis and oogenesis

Question 13

It is where the spermatozoa from spermatogenesis, fuse with the oocyte that is created from oogenesis and creates a zygote.

Answer 13

Fertilization

Question 14

Immediately after the fusion of the two gametes, the zygote would undergo rapid cell divisions which characterize this stage of development

Question 20

which forms the digestive system, lungs, and urinary system.

Answer 20

endoderm

Question 21

the process by which the three germ tissue layers of the embryo, which are the ectoderm, endoderm, and mesoderm, develop into different organs of the organism.

Answer 21
