Plants with small leaves live in extreme environments. Some plants have big leaves to make photosynthesis easier for the plant probably because it lives somewhere shady. Plants with small leaves have lots of light so big leaves are not required. The bigger the leaf the bigger the surface area so big and small leaves collect the same amount of light.
**Edit**
Additionally a big factor that stresses effective leaf sizing is the amount of atmospheric moisture and heat. Some plants will fix carbon in the night time, reducing the amount of water loss they experience through the stomata, but others do not: as they intake CO2, they also lose water due to the heat. Hence a cactus's leaves are thin needles. Doesn't allow for a lot of CO2 fixation (so slow growth), but there's very little evaporation, so they don't die easily. It's a tradeoff for many plants.

∙ 11y agoSome plants have single and clustered leaves, and some have clustered or compound leaves.Maple and Oak trees have simple leaves. Some such as horse-chestnut and locust trees, have leaves that grow in clusters. These are compound leaves. Others plants have leaves shaped like needles or spines.
Plants that live in the desert have long roots so when it DOES rain they are able to gather a lot of it. They also have small leaves and some have spikes so that other animals can't steal their water.
Plants like moss and ferns reproduce by spores. Some plants reproduce by sending out runners which will grow into new plants. Other plants will have parts such as leaves or stems which fall off the mother plant and grow into a new plant.
A small increase in temperature may help some plants, but will be damaging to others. A large increase in temperature will kill most plants.
Cuz they have more chlorophyll in the leaves and they need the chlorophyll cuz they are in the shade and need more size to get the sunlight
Leaves that have a small surface area lose less water.
Basically, to reduce the loss of water through their leaves. Some desert plants have a waxy coating on their leaves to do the same.
Because of the small leaves which some plants have, they can not live in nice and dry places and can't get enough oxygen and can't get produce carbon dioxide. Therefore they can only live in wet damp and dark places. Hopeful this answers your question.

Yes some plants have leaves which fall of like mango leaves . But there are some plants of which leaves do not fall , like oak leaves.
Yes, there are some plants in the desert with long leaves. A few examples:Palm treesYuccasSotol
False. Two large groups of plants could be seed plants and seedless plants, or vascular and nonvascular plants. All plants have leaves of some kind or another.
some have breathing roots that appear above water surface pneumataphores
Well the leaves on some plants are known for their excellent smelling.
Eucalyptus leaves can kill other plants. They are extremely toxic and just a few leaves around a plant can kill it. Of course some plants are immuned to the toxic poison.
To maximise the surface area for photosynthesis, plants increase the size of their leaves
There are several types of clover plants with tiny leaves. Some species of clover with small leaves include the Dutch white clover, sweet clover, and common white clover.
