Tropisms is the response to an external stimulus in a specific direction.
light, heat, and gravity!!!!=D
The four tropisms are: "Hydo-tropism" "Photo-tropism" "Geo-tropism" "Thigmo-tropism" MerchantMooMoo summons his milk!
We can't demonstrate an experiment of green plants because if sunlight is present the co2 produced in respiration will be used in photosynthesis. So we must conduct an experiment of green plants in a dark room.
The stimuli that plants respond to include light, water and gravity. Plants grow towards light (phototropism). Also in some plants the flowers will follow the sun as it moves across the sky. Plant roots grow towards water (hydrotropism). Plant roots grow towards gravity/towards the centre of the earth (geotropism). Source(s): I'm a biology teacher. this is bullcrap it is fake
OK there's 4 tropisms hydro tropism (when plant grows towards water) thigmatropism, (when plant grows towards touch) gravitropism (grows right side up is turned upside down) and photo tropism (grows towards light)
they are actions that a plant takes in order to increase its chance of survival. An example of a behavioral adaptation in plants are tropisms. Tropisms are the growth of plants toward sunlight.
Tropisms are plant's response to a particular stimulas. Tropisms demostrate that plants can response to light, water, gravity and chemicals. We, humans know what we want and with our knowledge we seek for it. Unlike humans, plants doesn't know what they want and how to look for it. So plants response to stimulus in order to get what they want and to survive. Plants turn towards light in order to make food. Tropisms helps plants to survive as plants cannot move and has no knowledge.
they make it grow naturally i hope this is useful to your question
plants need waterpoint made. period.. . . . . . .
Charles Darwin and his son did an experiment in 1880 using grass plants which led to the discovery of phototropism, this discovery led to many other scientists wanting to find out other tropisms
Tropisms are slow growth responses . plants respond to things like light , gravity and water.
its the air around them and the carbon dioxide...without the carbon dioxide, plants cant survive!
The three plant tropisms include geotropism, thigmotropism,hydrotropism and photoperiodism.
