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.
How do auxins cause hydrotropism?
Roots show positive hydrotropism and grow in the direction of water. This tropism causes problems in many cities where tree roots grow toward the drain pipes, and grow into the cracks, and plug up the drains. Hydrotropism causes plants to bend or turn toward water.
What do roots of a willow tree show as they grow toward the water?
Willow tree roots seek out water and have been known to even come out of the ground and grow into a container above ground that holds water. The process of the root going towards the water is called hydropatterning. Computed Tomography is allowing botanists to study this concept.
What distinguishes lower plants from higher plants?
Higher plants show some degree of complexity like in;tissue differentiation,vascularisation as they have the phloem and xylem Also there is an advancement in reproduction in that higher plants show alternation of generations unlike lower plants
Why do plants show movements to the sun direction?
phototrophism
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 positive thigmotropism?
Positive thigmotropism is a term used in plant biology. Thigmotropism is a growth response to touch either towards (positive) or away from a stimulus (negative). Roots of plants typically show a negative thigmotropic response when they come in contact with an object in the soil such as a rock. The roots will curve away from the object. Positive thigmotropism can be seen in vines. When a vine comes into contact with an object, the side of the vine that did not touch the object will grow slightly faster than the side with the contact. This causes the vine to curve towards the object and wrap around it, giving the plant added structural support. The plant is able to perceive the touch sensation and alter its growth pattern. There are many more examples out there ... but roots and vines are the most common. And remember: Tropisms only occur when the plant is growing.

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 is positive gvravitropism?
firstly there is no word as GVRAVITROPISM. When plants grow towards gravity it is called GEOTROPISM. its is mainly the root of plants that show geotropism; because they grow downward. but the stem show negative geotropism because it grows up in the opposite direction of gravity
Which of the following are square roots of 36?
The square roots of 36 are +6 & -6 Remember +6 x + 6 = (+)36 Also -6 x -6 = (+)36 Double minus becomes positive, so square roots must show both plus and minus answers. = +36
What does it mean to take a shine to someone?

When should you replant your ivy in a new pot?
In general, plants need repotting when their roots begin to come out of the drainage hole in the pot. When you lift the plant from the pot, if the roots are thickly clustered around the outside of the root ball, you probably need to repot. Usually plants that are stressed from having too many roots will show signs of distress, like wilting, yellowing, etc. Some plants, like Christmas cactus, actually seem to like crowded root conditions and won't flower when they are repotted.
