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.

Do trees grow horizontally or vertically?
vertically and horizontally. Vertically, they get taller as new growth sprouts from the top every year. Horizontally, they get thicker and branches get longer.
Does the rhizome of a fern grow vertically or horizontally?
horizontally
What cause the root to grow sideways?
Roots may grow sideways due to obstacles in the soil, seeking water and nutrients in a particular direction, or in response to environmental factors such as gravity or light. This phenomenon is known as root skewing or root gravitropism, where roots grow horizontally instead of vertically.
What do conifer trees grow instead of leaves?
Conifer trees grow needles and cones
List of plants that have roots that only grow down?
Most plants have roots that grow both vertically and horizontally to varying degrees. However, taproots such as carrots and radishes primarily grow downwards, as do fibrous roots of grasses. Deep-rooted plants like oak trees and dandelions also have roots that grow predominantly downwards.
Stems that grow horizontally are called?
Stems which grow horizontally are called stolons. Stems which grow horizontally are called stolons.
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 big is cumulonimbus?
Cumulonimbus clouds can grow to be very large, extending vertically up to 50,000 feet or more into the atmosphere. They can also spread out horizontally to be several miles in width.
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.
How do trees grow wider and fatter?
Trees grow wider by adding new layers of wood beneath their bark each year. These layers form rings that can be seen when the trunk is cut horizontally. As the tree ages, it continues to add new growth rings, causing it to grow wider and fatter over time.
What is a tropical tree with many trunks that begins with the letters M A N G?
The tropical tree with many trunks that begins with the letters M A N G is a Mangrove tree. Mangroves are trees and shrubs that grow in coastal saline or brackish water. They play a vital role in coastal ecosystems by providing habitat for various species and protecting coastlines from erosion.
What is the difference between creepers climbers?
Creepers are plants that crawl along the ground and spread horizontally, while climbers are plants that use structures or other plants for support to grow vertically. Creepers typically have a low-growing habit and root along the ground, while climbers have specialized structures like tendrils or twining stems to help them climb.
