Question 1

Differences between binary fission and mitosis

Answer 1

Mitosis (eukaryotic) is relatively slower and more complex than binary fission(prokaryotic). For binary fission there is no nucleur membrane to brake and no spindle fibres formed while mitosis must break it down and reform spindle fibres

Question 3

Types of Asexual Reproduction \

Answer 3

budding, fragmentation, spore formation, vegetative reproduction and parthenogenesis.

Question 4

Fission

Answer 4

occurs in unicellular organisms(bacteria and protozoans) and some multicellular organisms. The organism splits into two separate organisms of the same size. For prokaryotes fission takes 20 mins while in eukaryotes it takes 20 hours due to mitosis and cytokensis.

Question 5

Budding

Answer 5

It is an unequal division. The new individual comes from an outgrowth of the parent. Can occur in small mulitcelllular organisms and unicelluar organism.

Question 6

Fragmentation

Answer 6

This is where the body of an organism breaks into two or more parts (fragments) and then regenerates to form a new individual.

Question 7

Spore formation

Answer 7

Spores can also form sexually but spores created through asexual reproduction are called mitospores (mitosis produced).A cluster of spores sometimes form in a sporangium supported by hyphae (white thread like structures). Wind or water will disperse the spores when this structure breaks down.

Question 8

Vegetative reporudction

Answer 8

is an asexual method of plant reproduction that occurs in its leaves, roots and stem.

Question 9

Parthenogenesis

Answer 9

only occurs in women, Embryos are formed from unfertilised ova (via the production of a diploid egg cells by the female).
