Do people eat stems?
There are several plants that have edible stems; asparagus and celery come to mind.
Do onions have stems?
yes onions do have stems as you can see the stem sticking out in the middle and if they didnt have stems they wouldnt be able to hold on to their natural resorces - - Samantha 10 years old
How do you categorize a Paht Chee chart?
Hour,Day,Month,Year----Heavenly stems,-------Earthly stems.
What are the stems when pricing a 1797 penny?
On the reverse look at the knot in the ribbon that binds the wreath. If it has stems they will extend from the knot, one pointing to the last A in America the other to the U in United.
What is the difference between stem and trim?
Stems are thicker than trims
What happens to stems of plants placed on their sides?
The stems will start growing in upward fashion.
Stems and leaves grow using positive what?
stems and leaves grow using positive phototropism. That means growing towards the source of light. Mostly we reffer to the sun in this case. Even so, stems and roots can as well grow away from the source of light, that is negative phototropism.
What is the difference between positive and negitve geotropism?
Geotropism (also called gravitropism) is the turning or growth movement by a plant or fungus in response to gravity. Roots show positive geotropism (grow toward gravity - down) and stems show negative geotropism (grow away from gravity - up).
What signaled the stems to grow upward?
Warm sunlight.
Does geotropism determine the direction of growth?
Yes, geotropism DOES determine the direction of growth. Negative geotropism is when a section of the plant grows upwards. For example, stems grow upward. Positive geotropism is when a section of the plant grows downwards. In this case, a plant's roots would be the perfect example.
Roots growing with gravity and stems growing against gravity are examples of?
Geotropism
What are the examples of plants growing from stems?

What is an organism that shows positive and negative gravitropism?
Gravitropism (or geotropism) is a turning or growth movement by a plant or fungus in response to gravity. Charles Darwin was one of the first Europeans to document that roots show positive gravitropism and stems show negative gravitropism. That is, roots grow in the direction of gravitational pull (i.e., downward) and stems grow in the opposite direction (i.e., upwards). This behaviour can be easily demonstrated with a potted plant. When laid onto its side, the growing parts of the stem begin to display negative gravitropism, bending (biologists say, turning; see tropism) upwards. Herbaceous (non-woody) stems are capable of a small degree of actual bending, but most of the redirected movement occurs as a consequence of root or stem growth in a new direction.B_TCH SH_T MOTHER F_UCKER
What is an anophyte?
An anophyte is a moss or similar plant with cellular stems, with an upward growth and distinct leaves.
What two plant hormones that regulate plant growth and development?
Auxin controls the growth of the plant. Auxin in the roots of the plant inhibits growth whereas in the stems in the stems it encourages growth.
What is it called when a embryo's stems and roots have started growing?
SEEDLING
How do Positive photo tropism and positive gravitropism occur?
Gravitropism is responce to Earth's gravity. If you are talking about plants then a Positive gravitropism grows towards gravity (like roots of plant). A Negative gravitroism grows away from gravity (Like the stems of plants). Hope this help :P
