Cnidaria, have a single opening which serves as both the mouth and anus.
Ctenophora, feed with the aid of tentacles which capture prey with sticky threads
Echinodermata, feed by using a network of internal canals to pump water to different parts of their body
Calcarea/Silicea, live as suspension feeders, trapping particles that pass through the internal channels of their bodies.
Coral reef, sea anemone
Lack a mouth and gastrovascular cavity.
Only carnivorous species of its kind.
Cestode is derived from Latin, meaning "wheel bearer."

Tendency to spread disease
Their aid in pollination
Their segmented body structure
Can lay eggs
Do not undergo complete metamorphosis
Embryonic development can occur within a maternal pouch
Old World monkeys lack a prehensile tail while New World monkeys have a prehensile tail
New World monkeys do not have a prehensile tail while Old World monkeys do
Only New World monkeys are diurnal, or active during the day
Old World monkeys originated in Africa while New World Monkeys originated in Europe.
Multicellular dependent embryos
Gametangia (male or female)
Their stomata are not able to get CO2 in these conditions.
Moisture is needed for flagellated sperm.
The gameotophyte stage can not occur completely.
Nutrients are sparse causing the plant to have a shorter life span.
Their roots can anchor them more securely
The seeds were able to increase the surface area for nutrient absorption.
Were more sexually dominant by being heterosporous
Enabled plants to become more dominant producers in most terrestrial ecosystems
Have a better chance and reproducing with 2 different structures
Reproduce the fastest
Are the most recent type of plant
