3. Respiratory Systems of simpler organisms:
1. Monera, Protists, Fungi –
Exchange of gases occurs through
cell membranes. ( )
All or most of the cells
are in direct contact w/ environment
Thin
Moist
DIFUSUON

4. 2. Plants -
Through Leaves – cell membranes of internal cells surrounded by intercellular spaces of the spongy layer, ( ),
Stems ( ),
Roots – ( ) Diffusion
Stomates
Lenticels
Root Hairs

5. 3. Hydra - layers of cells/Exchange happens by the process of .2
DIFFUSION

6. The presence of in the blood increases its ability to carry .
4. Earthworm – Gas exchange occurs through the This is because of the secretion of mucus. The skin has many capillaries, so the blood passes through and picks up and gets rid of
The presence of in the blood increases its ability to carry
