What cells are impervious?
i am not a master in biology but something i know that in plants the bark cells are impervious to gases and water as they have a chemical called suberin on their walls.
How can you prove that bark cells are impervious to gases and water?
I asked u a question.. dnt ask me inturn
Name a type of cell or tissue found in a tree bark.?
It is Heartwood. (The Older xylem cells of heartwood no longer carry water).
Why would you find xylem cells in a tree's bark?
you dont
How do plants control their water supply?
by holding the soil in place with their roots

How does the corck act as a protective tissue?
as plants grow older, the outer protective tissue undergoes certain changes. a strip of secondary meristem replaces the epidermis of the stem. cells on the outside are cut off from this layer. this forms the several layer thick cork or the bark of the tree. cells of cork are dead and compactly arranged without intercellular spaces. they also have a chemical called suberin in their walls that makes them impervious to gases and water.
Why cork and bark of trees help in preventing loss of water?
It contains dead cells.
Well do how different types of water?
hardwood,such as oak, generally absorbs less water then softwood,such as pine, because of the amount of cells in the bark/stem.
Why does bark float in water?
it floats on water because bark contains air Bark floats in water because it is less dense than water.
Name a type of cell or tissue found in a tree bark.?
It is Heartwood. (The Older xylem cells of heartwood no longer carry water).
Does bark absorb a lot of water?
Will tree bark sink?
How does gaseous exchange occur in plant?
Gas exchange can occur in several ways for most plants. The leaves and young stems of plants have openings in the epidermis controlled by guard cells. The openings are called stomata. Carbon dioxide from the atmosphere will diffuse through the stomata and oxygen diffuses out into the air. They are normally open in the day light and closed at night. Trees with bark may have spongy layers in the bark called lenticels allowing gas exchange. Gas exchange will occur through the moist epidermal layers of the young roots. Oxygen from the soil will diffuse into the cells while carbon dioxide diffuses out of the cells into the soil. Plants submerged in water will have gases diffuse in and out of the cells from the water. Cypress trees have "knees" for obtaining oxygen in water logged soils. The knees emerge above the water into the air.
What is treebark made out of?
Tree bark is made of two layers of cells;the interior and exterior. The interior is the living part of the bark. The exterior is the dead part of the bark.
