Cell seeding density refers the number of cells (usually per square centimeter) that are placed into a flask during cell passage. If growth is wanted a typical cell seeding density would be around 5,000 cells/square cm, however, if a high confluence is needed it may be more appropriate to seed cells around 50-60,000 cells/square cm.
How to determine cell seeding density-
look at the cells in a hemocytometer. This is a small plate that has very small squares etched into its surface, which allows for counting of individual cells underneath a microscope to determine the density of the cells in the cell suspension, and this the total number of cells can be approximated.
Yes, because each plant needs a certain amount of space in order for it to grow. If you plant them too close together, then the plants will croud each other and there will not be enough room for them to grow.
A pot has a limited soil volume, so the more seeds you plant in it, the more plants there are competing for the limited soil resources available. Overcrowded plants tend to be tall and skinny, because they're fighting with each other for light. They also flower early due to the stresses of competition, and produce smaller, inferior fruit or foliage. Overcrowded plants are also more susceptible to diseases, especially fungal diseases that thrive where air circulation is poor and plants are stressed.
As population density gets higher so does the importance of direct competition. The higher the competition the less plants will be able to grow at an optimum rate.
yes
not really
Yes, though for each seed length and outcome are different.
yes Light has more effect. light would affect the direction of foliar growth, the direction of root growth is determined by gravity (with a few exeptions)
Optimum pH for germination of peas is 5.8-7. At a pH of 8 or greater the seed will not germinate.
in seed plants, the plants that you see are in the
Yes, seed plants are vascular.
the answer is yes , seed size does effect the growth of th plant. for example,an avocado seed takes a hole 2 months to start growing well.
They don't. Magnets and magnetism has no effect on seed or plant growth whatsoever.
cows
no
it does not. if the seed is put upside down, it will not usually effect the growth of the seed. the sprout still grows up, and the roots grow down.
Oxalic acid prevents seed growth by putting the seed into a stage of dormancy.....
Ok,yes if you do water the plants with different liquids the growth of the plants will be different and will effect the plants. Acid will kill the plants, some other liquids like a sports drink will probably make the plant have an odor,it all depends on the type of seed and the liquids and how mush of the liquid you are "feeding" the plant.And some liquids have nutrients or toxic solutions
Yes, though for each seed length and outcome are different.
because different plants have different germanation and growth times
Yes, music does in fact effect seed growth. My friend Alyssa explored that world when we were in 5th grade. If you play the music loud and set the plant by the speaker when it vibrates it loosens the soil allowing the plant to grow
Non-seed plants evolved from seed plants.
A seedling is a seed that has sprouted/or/a baby plant.
