What type of tropism do cactus plants show?
Phototropism is the type of growth that the desert cactus plant shows above ground. It grows in response to the high levels of heat and light in the desert. The above ground parts are called the shoots, and the below ground roots. The roots grow in response to the search for moisture in the soil.
What is the result of secondary growth in dicot plants?
It shows the number of years of the plant and enhance the rigidity of the plant.
What is the genotype of a pea plant that shows the recessive phenotype?
Pp
Which part of a green plant shows the greatest in chloroplasts by the end of spring?
Leaf.
What option shows a time period where new land plant might develop?
a
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
What is plant growth response to touch called?
Venus fly trap and the sundew plant (both carnivorous) respond to the touch of their prey. Mimosa pudica (called sensitive plant, touch-me-not, shy plant or tickleme plant) also responds to touch. The cells in the leaf quickly shed water, lose their rigidity and let the leaf droop away from the touch. After a few minutes the leaf returns to normal.
What process causes the plants stem to bend toward the light?
This is due to tropic movement(tropism) in plants in which the fixed part of a plant(such as stem) moves in response to a stimulus.If the stimulus is light(as you have asked) then it is termed as Phototropism.And further more stem shows positive phototropism.
What does each map shows?
the answer is gravity
A plant sits on a window sill over time the stems of the plant curve toward the light coming in the window this process is called?
This is due to tropic movement(tropism) in plants in which the fixed part of a plant(such as stem) moves in response to a stimulus.If the stimulus is light(as you have asked) then it is termed as Phototropism.And further more stem shows positive phototropism.
Which of these characteristics of a plant shows that it is a vascular plant?
it has a stem.
If a Urinalysiss shows Specific gravity is 1020 what does that mean?

What is going on when a girl has her period and it is on and off and then she takes a pregnancy test right after that and it shows positive?
She's pregnant if the test shows positive
How do you know a plant died?
When a plant becomes wilted, it shows it isdead.
A paleotologist finds a plant fossil that shows that the plant had seeds what can the paleontologist conclude?
It Was A Land Plant
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
How can sun's gravity cause tides on Earth?
Gravity pulls everything but water shows it. I am still looking for tides in a glass of water.
