They either store it in their trunks/stems like the baobab tree or the cactus. Or, they just need very little of it to survive.
helps them hold onto grass or plants
Because they are able to store extreme amounts of water and can hold onto it in case of droughts. However, if they get too much water, the can explode. this is very rare though.
an oasis but some are fed by small rivers that form during the few rainstorms of the desertAn Oasis
Earth is the only one we know of so far :)
Yes, humus does help soil hold water. Humus is a stable form of organic matter that improves soil structure, increases water retention, and provides essential nutrients for plants. It acts like a sponge, absorbing and holding onto water for plants to access during dry periods.
The past form of hold is held.I hold onto hope.They hold onto hope.She /She holds onto hope. (note: The word changes.)I held onto hope.He/she held onto hope.They held onto hope.
Water and vegetation is mainly found around natural spring areas (oasis), vegetation is also sometimes found above underground watercourses or shallow depressions where water can accumilate below the soil level. There are also numerous examples of rivers which flow through desert areas, which obviously have vegetation along the banks.
Water retention in soil refers to the ability of soil to hold onto water. It affects plant growth and nutrient availability by influencing the amount of water and nutrients available to plants. Soil with poor water retention can lead to water stress in plants, affecting their growth and nutrient uptake. Conversely, soil with good water retention can provide a consistent supply of water and nutrients to plants, promoting healthy growth and nutrient availability.
Many plants will not root in sand as there is little mineral content for nutrition, and little to grasp onto. Some grasses may root, shallowly, but can take hold in a group that is fed water and minerals.
Something to Hold Onto was created in 2002.
In order to understand why desert plants have cuticles (cutin) you first have to know what cutin is, it's function, and why some plants have it. Then you can begin to answer why plants specialized for desert climate have cutin. Cutin is a fatty, wax-like substance secreted by a plant's dermal tissue system. The dermal tissue is also known as the epidermis which is the outermost layer of cells on all young plant organs. If you consider all of this "waxy stuff" as a whole it is termed "cuticle,"similar to the cuticle above your nails. As you can imagine, wax is insoluble in water and therefore "water-proofs" the skin of the plant. In other words, it dictates how much water is lost through the epidermal cells by evaporation, ensures water does not enter, and also keeps other molecules from entering. The cuticle also protects again UV radiation. Regarding plant's evolutionary history, the adaptation of cutin provided a way for marine plant life to move onto land. Suppose if you were a marine plant and your entire body was surrounded in water, you would rely less on gaseous exchange and evolving structures or mechanisms to trap water within you. If you move onto land and are in hot, dry, desert climates water is scarce and you must adapt to survive. This is why desert plants have cutin. I hope that helps!
