When seeds germinate they are under the ground and as such are not able to detect any light source to grow towards however they are able detect the force of gravity just like humans do. No matter which way round you plant a seed the roots always grow down and the shoot grows up, the roots show positive geotropism (this means they grow in the same direction as the pull of gravity i.e. down) and the shoots show negative geotropism which is against gravity i.e. upwards. As soon as the shoot emerges above the soil it will then grow towards a source of light so that it can convert the suns energy into usable energy through photosynthesis. It is in the plants best interest to grow straight upwards so that it get as much light as it can and not be out competed by other plants.

Why would epiphytes grow on the branches of trees instead of on the forest floor?
so they get as much sunlight as the trees do.
How do climbers grow?
Climbers mainly grow in two different directions such as horizontally or vertically and they require support which mimic their direction of growth. Make sure you use strong enough support some climbers can place significant strain on buildings and support structures.
Why do sporangiophore grow vertically whereas rhizoids grow downward?
The sporangiophore grow vertically because it is positively phototrophic. The rhizoides being positively geotrophic grow downward.
Difference between trees and plants?
All types of organisms in plant kingdom are called plants. Only arborial plants are called trees.
How do leaves grow on a eucalyptus tree?
The leaves of eucalyptus trees, or gum trees, grow hanging down, rather than horizontally. This is a special adaptation which minimises evaporation and hence water loss (transpiration), as the leaves are not as exposed to sunlight. The leaves usually have equal numbers of stoma on each side, unlike trees which hold their leaves horizontally - they tend to have all or most of their stoma on the lower side. The leaves also tend to have a thick, waxy coating which also minimises water loss.
Where does paper grow?
paper doesn't grow! the trees grow and we make the trees into paper! paper doesn't grow! the trees grow and we make the trees into paper!
Why do most plants grow vertically?
Plants grow toward the sun. The constant movement of the earth makes the sun appear to move around, thus causing the plants to equal out straight. This is why you see trees that are on the side of a mountain at an angle instead of straight up. The sun disappears behind the mountain and the plant stops growing in a specific direction.
