Because it has loads of available water, for all practical purposes in indefinite amounts, the banana leaf can grow to huge sizes. Since the surface area is greater, large leaves are more vulnerable to freezing at night when the temperature dips.



Similarly, it is asked, why do banana trees have big leaves?

Large-leaved plants like bananas and palms tend to live in the tropics, while small-leaved plants like heather and clover are found closer to the poles. But large leaves absorb more of the sun's heat and get hotter than small ones, suggesting they should be found in cold regions, not the tropics.

Secondly, how big is a banana leaf? Banana leaves are large, wide, elongated, and slightly rounded, averaging two meters in length, a half a meter in width, and 8-12 leaves per tree. The surface of the leaves are waxy, flexible, and glossy, and range in color from lime, olive green, to dark green.

Keeping this in view, why are rainforest leaves so big?

Large leaves are also poorly adapted to hot desserts, because they tend to overheat during the day. Large leaves also allow tropical plants to capture more sunlight energy and together with a ready supply of water are able to convert this energy readily into rapid growth.

Why are some leaves bigger than others?

It comes down to the risk of overheating or freezing. Plants have a delicate balance to strike when it comes to their leaves. They need to be large enough to absorb lots of sunlight for photosynthesis, but not so big they use up a lot of water to cool those leaves through evaporation.

How much water does a banana tree need?

How Much Water to Use. Bananas require an average of 4 to 6 inches of water each month, or about 1 to 1 1/2 inches per week, depending on the season. However, overwatering can cause root rot. Make sure the soil drains well and does not have standing water.

How do you protect a banana tree from the wind?

Plant them near a hill, wall or building on the side from which most wind comes to provide some wind protection. This may not provide enough protection in a storm. You can also plant a row, or surround your banana plant with a strong hedge for a windbreak.

Are banana plants invasive?

Well-Known Member. Are banana trees considered an invasive plant in certain areas. I have been growing them for several years in Virginia and they multiply quite dramaticly and survive our cold winters with no winter protection, I don't even cut them back anymore until the next spring.

How big can leaves get?

They can grow up to 100-110 metres high with leaves between 10 and 30 cm.

What type of soil is best for banana trees?


Soil: Bananas will grow in most soils, but to thrive, they should be planted in a rich, well-drained soil. The best possible location would be above an abandoned compost heap. They prefer an acid soil with a pH between 5.5 and 6.5. The banana is not tolerant of salty soils.

Do plant leaves get bigger?

The number of leaves on a plant is fixed mainly by the genetics of the plant which controls the arrangement of leaves on the stem. Of course, a bigger plant has more leaves, but it is not a simple matter to switch growth into extra leaf mass.

How big do banana trees get?

Cultivated banana plants vary in height depending on the variety and growing conditions. Most are around 5 m (16 ft) tall, with a range from 'Dwarf Cavendish' plants at around 3 m (10 ft) to 'Gros Michel' at 7 m (23 ft) or more. Leaves are spirally arranged and may grow 2.7 metres (8.9 ft) long and 60 cm (2.0 ft) wide.

Do bananas grow trees?

Bananas do not grow on trees. Rather, they grow from a root structure that produces an above ground stem. The plant is specifically classified as an arborescent (tree-like) perennial herb; in fact, it is the largest herbaceous flowering plant. The banana plant being an herb is that the banana itself is a berry.

What plants have drip tips?

The leaves of forest trees have adapted to cope with exceptionally high rainfall. Many tropical rainforest leaves have a drip tip. It is thought that these drip tips enable rain drops to run off quickly. Plants need to shed water to avoid growth of fungus and bacteria in the warm, wet tropical rainforest.

How do I get big pothos leaves?

Pothos Ivy, more than most, responds to these factors by developing large leaves - sometimes spectacularly large leaves. In general, high temperatures, high humidity, high nutrient uptake, rapid growth and low light are involved in the development of large leaves.

What are buttress roots in the rainforest?

Buttress roots are large, wide roots on all sides of a shallowly rooted tree. Typically, they are found in nutrient-poor tropical forest soils that may not be very deep. They prevent the tree from falling over (hence the name buttress) while also gathering more nutrients.

How do plants survive in a rainforest?

Many plants have waxy leaves that help repel the rain. Rainforest plants must either adapt to living with little sunlight under the forest canopy or grow quickly and find ways of reaching the sunlight above the canopy. For example vines quickly grow up the trunks and branches of trees to reach sunlight.

Why do plants have broad leaves?

Most plants have large, flat leaves that are known as broad-leaves. Broad-leaves are usually grown quickly and don't take much energy for plants to grow. They are also often easily eaten by herbivores but are very efficient at photosynthesizing because of their large surface area.

Why do leaves have large surface area?


The leaves are the organ for photosynthesis. Most leaves are broad and so have a large surface area allowing them to absorb more light. A thin shape. A thin shape means a short distance for carbon dioxide to diffuse in and oxygen to diffuse out easily.

Which part of a plant can grow into a fruit?

Each seed contains a tiny plant called an embryo, which has root, stem and leaf parts ready to grow into a new plant when conditions are right. Another part of the flower (the ovary) grows to form fruit, which protects the seeds and helps them spread away from the parent plant to continue the cycle.

Why do rainforest plants have more stomata?

If water is plentiful (not limiting) then plants may have more stomata, which allows for greater access to water (and the hydrogen ions needed), and increased support for herbaceous tissues.
