How do plants deal with harsh environmental conditions?
They adapt to where they live.
Some environmental factors that affect plants are the amount of light and temperature. Humidity and amount of water available also affect plants.
Because it allows them to reproduce much more quickly. When environmental conditions are poor, plants reproduce sexually because it allows them to produce tougher offspring that will withstand the bad conditions. If a plant is not healthy because of its environment, it can mate with a more healthy plant to produce healthier offspring. This, however, is a much slower form of reproduction which is why plants normally reproduce asexually.
What is the ability of a seed to postpone development during harsh environmental conditions is known as?
there is one plant that survives in the very harsh deserts that is cactus.
All plants have complex chemicals in their sap that helps regulate heat, cold, moisture and even some chemicals that help resist insect attacks. Evergreen trees and bushes even have a form of anti-freeze that keeps them from freezing in extremely cold temperatures.
What environmental conditions make plants growing on the dunes different than plants growing in the forest?
dunes; well drained, slightly saline in nature, very little or no organic material (low water retention), normally exposed to sea spray or strong on-shore winds. Releative humidity can vary depending on locationjungle; humus rich soil, at times can be water-logged and low in atmospheric oxygen, environment is normally protected from high wind, but can be prone to heavy rains and high incidence of lightning strikes. Normally high relative humidity
Cacti have adapted to extremely arid and/or semi-arid hot environments. They show a wide range of features which conserve water. Their stems have adapted to become photosynthetic and succulent, while the leaves have become the spines for which cacti are well known. The bodies of many cacti are thick and have water-retentive tissue Most cacti have a short growing season and long dormancy. They also have the ability to form new roots quickly. Two hours… Read More
Their internal osmolarity has to at least equal the osmolarity of the external environment or the cell will lose water to osmosis and die.
the curticles on the firstly avoid the lost of excess water hence duringextreme conditions the water is been use up to carry out metabolic activities in the plant.during this extreme conditions the stomata plays a very important role.Please post more information... the question is EXTREME CONDITIONS this includes not only heat, but cold, altitude, salinity, water logged soil etc. Once there are more answers I'll collate them
Depending on the availability of water, plants can grow as hydrophytes, mesophytes and xerophytes
Cooling of a plant results in the metabolism of the plant slowing down, this in turn reduces the demand for food and nutrients and the amount of water that is required to sustain the plant.Extremely high temperatures. Studies on certain plants have shown that at high temperatures certain plants again slow their metabolism and even enter a state of near "suspended animation" in an effort to reduce stress on the plant. At temperatures approaching 40… Read More
Which is an example of phototropism helping a plant survive its particular environmental conditions?
At the edge of a forest, a tree angles away from the woods.
They take in O2 throught the stomata in their leaves and pump the O2 through the aerenchyma (air spaces) to the roots.
They will usually have needle like leaves, not flat ones, so as to avoid water loss. They may have fleshy roots to store water. Their roots will be deep. They may be salt tolerant
( this is only 1 way sorry ) plants adapt in the rainforest by increasing their size because they need to catch the most sun light and by getting bigger they have more surface area to catch the sun. (lol hope that helped you
Heat and wind.
Adaption help by making the plant live in their environment. For example say a cactus was living in Antarctica. It would not make an adaption to the environment because it is too cold.
Different plants need different conditions. You will help get the right answers by identifying the plant.
Cotton plants need a light and warm place to grow. It also needs shelter.
oxygen levels, light and carbon dioxide levels.
through respiration process, not absorbing too much water, growing in an open space to easily take carbon dioxide
The swollen leaves are narrow so that less sunlight can be taken in for the plant because it already gets alot since its habitat is a warm enviroment so less sunlight would be ideal for it. So therefore less sunlight is taken in at the top of the leaves.
spring and summer because these are the season of fast growth.....
The ideal conditions for a plant to grow in are:*Sufficient Sunlight (So that the plant can produce energy and food for itself via photosynthesis)*A place with suitable temperature *Good Soil*Protection (from bugs, pests, pets, etc.)*Water (to keep the soil moist)
Not so much. Linnaeus started classifying plant by the differences in their reproductive organs. The broad classification by living conditions would probably split plant into water and land based plants.
Plants adapt to dry conditions in a variety of ways, but many respond to dry conditions by storing large quantities of water, which can be used in times of need. For example, cactuses store water in their trunks and stems, while aloe plants store water in their leaves. Additionally, plants that live in dry areas often evolve thick outer cuticles that can help retard the rate of water loss. Some plants will discard their leaves… Read More
Plants that have cells in them to protect themselves from wet conditions; furthermore in hot conditions, wet plants (ones with storages of water in them), would have that adaption and visa versa with wet conditions. Hope this helped!
The rate of photosynthesis varies under different environmental circumstances and conditions because mostly of what the condition or environment does to affect the sunlight coming through the atmosphere in order to reach the plant. If a plant was located in a sunny tropical area, they would receive a lot of photosynthesis, because there is very little cloud cover. In some other parts of the world, however, plants would probably die, if they don't adapt, because… Read More
Why do some plant species require shaded conditions while other plant species require bright sunlight?
Different species of plants have different pigment molecules that utilize different wavelengths of light.
its sunflower and rose.
Simply because it depends on the type of light it is grown under.Otherwise the best type of light for a plant is sunlight.
rich soil with lots of minerals. and room to grow
Cotton likes it hot during the main growing season. It uses a lot of water and in the fall when it is time to pick the plant is killed so the bolls will open so they can be picked. Today cotton is picked with a big machine called a cotton picker, taken to a cotton gin, and then put in bales to be sold. It takes about 3-4 runs with the cotton picker to get… Read More
The conditions necessary are: light water sun energy carbon dioxide
what conditions are ideal for the growth of clover plants
its the soil nd water
A tuber stores plenty of food material along with propagules in the form of buds and remains dormant under unfavorable conditions.
Do scientists assume that plants and animals in the past required the same conditions as similar plants today?
Under arid conditions C4 plants fix carbon dioxide more efficiently than C3 plants because C4 plants?
