Porifera- with Simran (incomplete)

**Porifera means 'pore bearer' and are essentially sponges.
1. Feeding - herbivore, carnivore, omnivore, filter feeders, detrivore, parasites
=> Filter feeders which means they filter food out of water. (intracellular digestion:  digestion takes place inside the cytoplasm of the sponge.)
2. Respiration - take in O2 and release CO2
=> No respiratory system, everything is done by diffusion within individual cells.
3. Circulation - transport of nutrients, O2 etc. through body
4. Excretion - expelling nitrogenous waste products (ammonia - urea)
5. Response - senses, nerves
6. Movement - muscles/skeleton
7. Reproduction - sexual and cloning, life cycles

1. Mosses 

A) The moss were growing in areas where nature had been disrupted. One picture shows the moss on a tree trunk of a tree that has been cut down. The second picture shows moss on a cut down tree. They were both with  surrounded with many other plants.

B) Mosses need to live in moist environments because they have sperm that swim in water to reproduce. Also water is needed for nutrition.

C) Mosses grow low on the ground because they do not have a vascular system and absorb water directly. Mosses can grow on rocks because they grow in any moist environment and are the first link between aquatic and terrestrial plants.

2. Ferns

3. Gymnosperms 

Root, stems, leaves

- is it a monocot or dicot

- how do you know? Talk about arrangement of vascular bundles and label them to show you know the difference. Maybe compare and contrast.

Stems - dicot
