Lungs
yes.
The thousand upon thousand tiny air sacs called the alveoli, which is the where gas exchange within the lungs take place :)
The spongy layer in a plant leaf facilitate better gaseous exchange for photosynthesis and respiration.
it's a biscuit :) Gaseous exchange and photosynthesis
Yes, the lungs are made up of two spongy sac -like organs located in the upper chest that help in oxygenating the bloodstream.
Lungs.
All plant cells respire all of the time and need to exchange gases. The main gas exchange surface in plants are the spongy mesophyll cells in the leaves. Leaves have a huge surface area, and the irregular-shaped, loosely-packed spongy cells increase the area for gas exchange even more.
Spongy Layer - A layer of the mesophyll. The spongy layer consists of chloroplasts and parenchyma cells, and relatively large intercellular spaces. It is far less ordered than the palisade layer, and the intercellular spaces are important in gas exchange and transpiration.
So that the cell can breath.
It doesn't have organs, it's a collection of single celled organisms.
Mesophyll In between upper and lower epidermis of leaf is mesophyll tissue. In the dorsiventral leaves, mesophyll is divisible into upper palisade cells and lower spongy parenchyma. The palisade cells are mainly involved in photosynthesis and spongy parenchyma in gaseous exchange.
