What is it called after a seed begins to grow?
Germination is the time when a plant begins to grow. At that point, the plant is sometimes called a seedling.
What is the soil type for timber pile?
A timber pile is not soil, it's a pile of timber.If a substance does not support plant growth or have the capability of supporting plant growth, it is not soil.If the timber pile decomposes to a point where the remaining organic matter can support plant growth, it would be considered an organic soil, provided the layer of organic matter was thick enough. Organic soils are known as Histosols in US Soil Taxonomy.
Would a plant still grow at the light compensation point?
Yes, a plant can still grow at the light compensation point. The light compensation point is the level of light intensity at which the rate of photosynthesis equals the rate of respiration in a plant. At this point, the plant is able to produce enough energy through photosynthesis to sustain its growth and metabolic processes.
What happens when a plant receives more light energy than it's composition point?
Plants can store the excess of energy or use it to growth.

How do you measure tree seedling density?
One way to quantify plant cover is to use the point-intercept method. This will give you a percent cover for total vegetation or for each species This will give you data similar to estimating percent. However, the advantage of this is that you don't have to estimate -- you make an actual measurement.
Why does abnormal germination occur?
There are a number of reasons for this (I have listed some, but sure there are more):1. Inherent genetic defects in the embryo, sometimes the embryo doesn't abort, after germination the defects or mutations prevent the seedling from developing in a normal way and normally the seedling will die. You should however bear in mind that genetic mutations are the ways that plants adapt to their environment over time. The mutations that do make it and survive eventually pass on their genetic advantages to the subsequent generations.2. Changes in environment during germination. Once germination is initiated it cannot be stopped or paused, take the example of a seed which starts to germinate, the testa spits and the radical emerges; for reasons beyond the control of the seedling the weather changes and the is no longer an adequate supply of water to continue germination. The seedling at this point is committed and cannot crawl back into its seed coat, in most cases if the radical suffers to much damage at this point the seed will not have enough stored resources to continue and will die.3. Pathogens. Most notable of these are fungal spores; one of the main ones is Pythium, this can cause pre and post emergence "damping off". The parasitic fungus attacks young soft plant growth, invading the seedling and killing it. Pre-emergence damping off happens before the seedling "breaks ground" resulting in the notion that the seed has not germinated, but it has and has been killed off before it could emerge properly.4. Age of the seed also is a significant role, as the seed ages its "vigor" deteriorates, the seedling looses ability and strength to make a clear "break" from the seed coat, resulting in a deformed seedling (which will normally die)
What is the relationship between the seed and germination?
A seed is needed if you want to grow a plant- you can't have a plant without a seed. Germination is the first stage of the plant's growth. It's when the seed has JUST sprouted, and sometimes the green that comes out, is very small- the point is the plant is starting to grow, and may continue to do so.
Where is the exponential growth happening in the graph shown above?
point a.
How do you get your plant branch bushier?
You should snip off the growing point to stunt growth lengthwise and promote proliferation from the nodes on the branch. Within one season it will be very noticeable and lush
How does salt in soil affect humans?
Salinity becomes a problem when enough salts accumulate in the root zone to negatively affect plant growth. Excess salts in the root zone hinder plant roots from withdrawing water from surrounding soil. This lowers the amount of water available to the plant, regardless of the amount of water actually in the root zone. The main point is that excess salinity in soil water can decrease plant available water and cause plant stress. Decreased plant growth translates into less agriculture to sustain human population and surrounding ecosystems.
