movement organs
- muscles
- skeleton
types of skeletons
- endoskeleton
- exoskeleton
- hydroskeleton (earthworms)
types of reproduction
- sexual - genetic diversity
- asexual - increase their numbers quickly
asexual reproduction
- fragmentation
- budding
- parthenogenesis
zygote life cycle
fertilization -> morula -> blastula -> forming germ layers -> neurolation -> organogenesis
fertilization
sperm and egg unite into a zygote
cleavage
rapid cell division, creating a ball morula
blastula
forming a hollow ball called blastula
gastrulation
forming primary layers
neurulation
development of the nervous system
organogenesis
formation of organs and tissues from the three primary layers
ectoderm develops into
brain, skin, nails
mesoderm develops into
skeleton, muscles, blood vessels
endoderm develops into
digestive system, organs, respiratory tract
protists ch
- damp or aquatic environments
- motile
- small in size
protists grouped into
- Flagellates - long flagella
- Amoeboids - pseudopodia
- Ciliates - short cilia
- Sporozoa - from spores

Flagellates
- long flagella to move
- multiply by binary fission
- some are parasites

- trichomonas vaginalis
- trypanosoma
Trichomonas vaginalis
causes infections in female vagina
trypanosoma

- fever, headache, fatigue, coma, death
euglena structure
