Hi Students, Please, where possible, rather than simply loading a Word doc, cut and paste the text into the wiki. If you are going to simply load a word doc - provide some introductory text on the wiki page to help others navigate the site and select the work they want to read.

REPRODUCTION: biological process by which new individual organisms are produced. Fundamental to all life; may be sexual (requires two individuals one of each sex) or asexual (by cell division).

A sea anenome can reproduce sexually or asexually, below is some information about both.



Asexual Reproduction:

ASEXUAL REPRODUCTION is when an organism reproduces by cell division. Cell division looks like:



There are a variety of ways in which asexual reproduction occurs the following are descriptions of the most common:

Budding – the offspring grows out of the parent (Hydra’s)

Gemmules – (internal buds) the parent releases a specialised mass of cells that can develop into offspring. (sponges)

Fragmentation – the body of the parent breaks into distinct pieces, each of which can turn into an offspring.

Regeneration – if a piece of a parent is detached, it can grow and develop into a completely new individual. (echinoderms – starfish example)

Parthenogenesis – a complex reproduction process that involves the development of an egg that has not been fertilised into an individual (these organisms have no sex chromosones, animals such as bees, wasps, ants and some fish and reptiles can reproduce in this manner).



Below is a link to short slideshow that I put together using "donuts" that helps explain the process of cell division (mitosis) that results in asexual reproduction. 

Sexual Reproduction:

Sexual reproduction requires two organisms. Each organism has specialized sex cells called gametes. <span style="color: #403c3c; font-family: Arial,Helvetica,sans-serif; font-size: 190%;">There are two primary forms of sexual reproduction; fertilisation and pollination. <span style="color: #403c3c; font-family: Arial,Helvetica,sans-serif; font-size: 190%;">Animals have sperm (male) and ovum (female). <span style="color: #403c3c; font-family: Arial,Helvetica,sans-serif; font-size: 190%;"> Plants have pollen (sperm) and ovum (egg). <span style="color: #403c3c; font-family: Arial,Helvetica,sans-serif; font-size: 190%;">Sexual reproduction happens when the two sex cells fuse together (fusion) to create a new and genetically different offspring. <span style="color: #403c3c; font-family: Arial,Helvetica,sans-serif; font-size: 190%;">Sexual reproduction allows for more genetic diversity in the offspring.

<span style="color: #403c3c; font-family: Arial,Helvetica,sans-serif; font-size: 190%;">Example of Sexual Reproduction through Fertilisation:



<span style="font-family: Arial,Helvetica,sans-serif; font-size: 160%;">Sea Anenomes will release sperm or eggs into the water. Sometimes the sperm and eggs meet and then a new anemone will begin to form. It can take a couple weeks before the anemone fully develops and can settle onto rocks.
