Name 3 unusual plant stem adaptations.?
Some adaptations include trees with thin, smooth bark. They don't need thick bark to keep them from drying out because the rainforest is so wet. Trees often have buttresses, large branching ridges near the base, for support because their roots are often shallow and they grow tall to reach the sunlight. Many plants in the rainforests have adapted leaf shapes that help water drip off the plant to avoid too much moisture, which might make bacteria and fungus grow....!!
Plants adaptations in the Philippines?
Is there any plants adaptations in the Philippines? I'm doing a biome project on the Tropical Rainforest and Philippines is a good choice. So anyone please, please, please does anyone one know. All i want to know is 3 plant adaptations and that's it. Thank you! =]
What adaptation allowed plants to live on land?
the vascular system! this help with support and nutrient transplant also the cuticle layer helped alot, preventing drying out.
What are some adaptations of aquatic plants?
Adaptations are many and varied. Many aquatic flowing plants have leaves that lie flat on the water for maximum sunlight collection. The stems of many aquatic plant have large air-filled areas to increase buoyancy. Many fruits of aquatic plants float on water, which increases dispersal as fruits and sees float away. Plants like cattails or reeds however may hold their fruits high above the water for wind dispersal. Many aquatic plants have deep, anchoring roots, but some, like duckweeds float freely and allow their roots to drift in the water below them. One aquatic plant is eel grass, which has adaptation for living in salt water.
What are the three adaptations of plants needed to survive on land?
Water conservation (they need to maintain water within them, now that it no longer surrounds them) Support mechanisms (without water to support them, they need to develop a different mechanism of support) Changed fertilisation strategy (they cannot just release gametes into the water, but need to develop new methods of getting male and female gametes to meet)
What are adaptations that enable plants to reduce water loss from their leaves?
* Fewer stomata, the pores in the epidermis or skin of the leaf on the leaf can reduce water loss * In hot dry climates many plants open their stomata only in the cool of the evening. * Small leaves (totora, lavender) have a reduced surface area to enable plants to conserve water, as do feathery, filigree leaves (romneya, eschscholzia or Californian poppy). * Needle-like foliage (grasses, pine trees) has a very small surface area that looses very little water. Some of these plants can roll their leaves inwards, further reducing surface areas and water loss. * Leafless plants, such as brooms, have lost their leaves altogether with stems undertaking essential photosynthesis and food production. * Grey or light coloured foliage reflects light, reducing heat and thus water loss from transpiration * Thicker cuticles, the outer waxy coating on leaves, slows transpiration; many coastal plants have a thick glossy coating on the leaves, reducing water loss and also protecting from salt-burn. * Silver hairs coating leaves reflect light and help to lower temperatures inside the leaf, as well as reducing the effect of drying winds. * Thick fleshy leaves can store water; many succulents have thick leaves that, when bruised or broken, contain a great deal of moisture. Thick waxy cuticle Found in many evergreen leaves, the cuticle cuts down water loss in two ways: it acts as a barrier to evaporation and also the shiny surface reflects heat and so lowers temperature. Sunken stomata Stomata may be sunk in pits in the epidermis; moist air trapped here lengthens the diffusion pathway and reduces evaporation rate. Leaf rolled with stomata inside This adaptation is found in Marram grass (Ammophila). As can be seen from the image left, the inner surface is covered in hairs. The rolled leaf and hairs both serve to trap moist air so reducing transpiration. In addition, a smaller surface area of leaf is exposed to the drying effects of the wind. Small leaves Many xerophytic plants such as pine and heather, have small, needle shaped leaves which are often circular in cross section. This reduces the surface area and hence the evaporating surface.
What are the adaptations of a water hyacinth?
The primary adaptation of the water hyacinth,Eichhoria crassipes , is its hollow bulbous stem below each leaf. These allow the plants to float, keeping the leaves and flowers above the water so they don't rot. The water hyacinth mainly reproduces through stolons. This adaptation allows for a single plant to produce approximately 3,000 new plants in as little as 50 days or cover 600 square meters in as little as a year. Also, the water hyacinth seeds are adapted to be dispersed by birds and can remain viable for up to 20 years.The water hyacinth has other adaptations that allow it to grow and spread rapidly in freshwater. Its swollen leaf stalks are hollow and filled with air. This allows it to be the only large aquatic herb that floats unattached from the bottom of its water source. The roots remain underwater in a thick mat, allowing the plant to obtain enough sunlight for photosynthetic processes. They have also adapted to withstand extreme temperatures, high pH levels and even toxic water.Water hyacinths are extremely tolerant of heavy metals and can contain large amounts of them. This makes the plant a possible resource for bio-cleaning industrial waste. They have also been well known to remove toxic materials such as cyanide from water.
What are 5 different adaptations plants have to keep from losing water?
The following are those adaptations = 1) Lesser number of stomata = A lot of water is lost through the process of stomatal transpiration . Reduction in their number reduces the rate of transpiration and helps in water conservation . 2) Location of stomata only on the lower leaf surface = Some plants ( desert plants ) show total absence of stomata on the upper surface of their leaves . They are located only on the lower surface where direct sunlight can not reach and thus reduce transpiration . 3 ) Sunken stomata = this adaptation is found in plants like Nerium and Cycas . The stomata are located in pits on the lower surface only . This helps to reduce transpiration . 4 ) Thick cuticle = Desert plants have thicker cuticle on their leaf surface to reduce cuticular transpiration . 5) leaf reduction =This is found in Cacti . In these plants the leaves are dispensed with to reduces transpiration . As a consequence of which the function of photosynthesis is taken over by the stem itself . These stems are flat , and green and look like leaves . These are called 'Phylloclades ' 6 ) Water storage tissue - So called Fleshy plants like Aloe , and cacti show development of water storage tissue within the leaves or stem . the tissue has a lot of mucilage . It has good capacity to store and retain a lot of water.
What are five major adaptations that allowed plant to colonize the land?
1) Desiccation- Cuticle & stomata to protect against dehydration. Survival on land requires an ability to resist and repair damage from desiccation . The first bryophytes evolved specific repair mechanisms using genes called rehydrins. Bryophytes evolved enclosed structures to protect gametes and embryos from desiccation called gametangia. This movement towards adapting to land's dry conditions was likely assisted by the first symbioses with fungal partners. 2) Structural support (cellulose & lignin) also roots as both anchors and a means of extracting water (& soluble nutrients) from soil. 3) Vascular nutrient movement rather than passive diffusion 4) Reproduction – pollen & seeds - haploid life stage become reduced then miniature. Central cell, double fertilization so the zygote has endosperm- the seed. Protected seeds in ovaries and floral symbioses with pollination partners.
What are the adaptations a dandelion has to make it a better competitor than other plants on a school field ?
The dandelion produces seeds maily in spring but continues through summer and autumn. The bitter leaves mean that not many animals eat it, so one flower can survive for many years. Dandelions are also adapted to being disturbed, so being moved doesn't limit their ability to grow. The deep, twisted, brittle root makes it difficult to remove entirely so unless you remove it entirely it will just regrow. The dandelion has a rosette of leaves at its base to help it compete with the surrounding grass. They can grow almost anywhere because of their resiliance, and their small parachute like seeds, mean that they can be blown many miles from their mother plant.
