I dont think plants need leaves. They need ROOTS. But if I'm wrong sorry I'm not sure. Try goign to like some plant site and ask.
Some plants like mushrooms and fungi can survive without sunlight.
To maximise the surface area for photosynthesis, plants increase the size of their leaves
Without animalscarnivorous plants wouldn't survive because that's their food
Some examples of plants that do not have leaves include cacti, succulents, and certain types of fungi. These plants have adapted to survive in arid environments by storing water in their stems or other parts of their bodies instead of using leaves for photosynthesis.
Plants in the taiga have adaptations to survive the cold temperatures and lack of sunlight. They have needle-like leaves to reduce water loss, shallow roots to absorb nutrients from the thin soil, and some plants can store energy reserves in their roots or stems to survive the long winters. Additionally, some plants in the taiga, like conifers, have a waxy coating on their leaves to protect against freezing temperatures.
Plants can typically survive for about 1-2 weeks without water, but this can vary depending on the type of plant, its health, and environmental conditions. Some plants may wilt or show signs of stress after just a few days without water, while others may be able to survive longer periods of drought. It's important to water plants regularly to keep them healthy and thriving.
These plants have such leaves because wider, flatter leaves will catch more sunlight. Sunlight is needed for plants to survive, so when they're in the shade they adapt to be able to get more sunlight.
I have one and it doesn't have a tree but some sticks and leaves would help
Some houseplants will survive perfectly fine, with just fluorescent lighting. Pothos is one of them, I know for sure.
Leaves get their green colour due to presence of a plastid called chlorophyll. This does the function of absorbing sunlight required for photosynthesis. Hence plants which survive on photosynthesis have greener leaves.
Plants that need ample water and those without adaptations would not thrive in dry forests. To survive in a dry forests, plants must have the adaptation of deciduousness, dropping its leaves once the rains end, which halts photosynthesis which produces water losses which causes the plant not to survive in the dry season. Some plants have other adaptations, such as green bark, which allows photosynthesis to continue even when the leaves have been dropped, and others have water storage tissues that allow them to survive during the dry season by drawing on the stored water. Others have an extra, waxy layer on their leaves that slows water evaporation, and others close their leaves at night which slows water loss.
In general, animals cannot survive without plants because plants are the primary producers of energy in most ecosystems. Animals rely on plants for food and oxygen, as well as for habitat and shelter. Without plants, the entire food chain would collapse, leading to the extinction of many animal species.
