parmecium caudatum

parmecium caudatum

a protozoan, a type of  heterotrophic protist that reproduce by binary fission

2

Type of  cell division

Q image thumb

Mitosis results in two daughter cells that have the same number of chromosomes as the parent cell.

 

3

Q image thumb

Meiosis results in four cells that have half as many chromosomes as the parent cell.

I. Asexual Reproduction- Forming buds by mitosis, that become new polyps

II.  Sexual Reproduction- (Diecious- male and female medusa)
.Egg is fertilized by sperm

.Zygote is created

.Develop into blastula

.Develop into plantula larva

.Develop into polyps

.Polyps can branch – they have many feeding heads because they are one time use only

.Reproductive polyps- gonangium – produces medusae

.Medusae swim, cluster and relese sperm and eggs into water to be fertilized

budding

Hydra Polyps, freshwater polyps

only have polyp stage
form gonads on side of body
or asexually reproduce via buds

The 3 types of life cyles that occur in protist

1. haploid adult

2. diploid adult

3. alternation of generations
