It's green, it has spots of chloroplasts round the outside of the inside and a big vacuole (air space) inside. See the related links below for more information.
Depends on the plant. Most plant you are familiar with would not thrive near an ocean with all the salt in the surrounding air.
Water, wildlife, and wind are ways in which spinach seeds disperse. The aquatic plant which is known as water spinach is most likely to disperse by water since its air pocket-filled labyrinthine seeds can float and disperse with water currents. The terrestrial plant tends to disperse by wildlife and winds.
Seeds disperse to avoid competing with their parent. An acorn seed sprouting underneath the canopy of its parent tree would be starved for sunlight and would most probably die. An acorn that was hidden by a blue jay under a rock in an open field (and then forgotten) would have an excellent chance of growing to maturity. (Providing something didn't come along and eat it.)
If the building is not air tight the presure should be just about the same inside or outside. If all the doors and windows are shut and you turned on the heat, the presure may be slightly higher inside.
when you grow a plant such as a vegetable when you plant it not only your planting seeds but in some seeds there's extra seeds in it which is smaller then the seed so as it grows the extra seeds get inside of the plant.
seeds need some conditions to germinate which they do not get inside a sealed packet. the conditions are : air, moisture, warmth. in other words it needs water, air and favourable temperature to germinate.
"Where" should you plant trees to save on the air conditioning costs of a building?
Try covering the plant and pot with plastic wrap or a bag so that it is air tight. Wait for awhile and the insects should suffocate.
Seeds travel through the air with wind. Flowers drop seeds and the air carries them.
When the seed heads have 'dried on the plant' cut and place in a paper bag, lightly tie to allow air circulation and then hang in a cool dry place over winter. When conditions are favorable in Spring, plant seeds
its bulding full of air
it get's despersed easily when it flies through the air and seeds disperse in the atmosphere and produce a new plant
Explosive or splitting action
No the seeds of poppy and pea do not travel by air.
The air pressure should be lower inside than outide
It should be inside the air cleaner housing.
