what determines which plants to grow where

Answer: Stems hold the plant upright and support it. They also transport water, minerals and sugars to the leaves and roots.

How do plants know where the sun is?

Many plants are known for their ability to track the position of the sun in the sky by a process called solar tracking or heliotropism. Some plant species like the sunflower plant orient their leaves so they will be perpendicular to the sun’s rays throughout the day to maximize photosynthesis, as the movie below shows.

What makes the shoots grow upward and the roots downward?

The roots grown downward in the direction of gravity, which is positive gravitropism, and the shoot grows upward away from gravity, which is negative gravitropism. The reason plants know which way to grow in response to gravity is due to amyloplasts in the plants.

What is the most important factor for plant growth?

The most important nutrients for plant’s growing needs are nitrogen (N), phosphorus (P), and potassium (K). Nitrogen is necessary for making green leaves, phosphorus is needed for making big flowers and strong roots, and potassium helps the plants fight off disease.

What is a genetic factor in a plant?

The genetic factor is also called internal factor because the basis of plant expression (the gene) is located within the cell. The environmental factor is considered external, and refers to all factors, biotic and abiotic, other than the genetic factor. Both plant growth factors interact in various ways.

What environmental and genetic factors affect plant growth?

Plant productivity is related closely to its growth and development, both of which are affected directly by environmental factors. These environmental factors that affect the cultivation conditions mainly include temperature, light, salinity, drought, nutrition, insects and pests.
