because they just do
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.

What leaves or clustered some plant have single or simple leaves?
Some 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.
What allows plants to live in the desert?
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.
Why rock are inhabited by small plants?
Rocks provide surfaces for small plants to anchor onto and access sunlight and nutrients. The cracks and crevices in rocks also offer protection from harsh conditions like wind and excessive moisture loss. Additionally, tiny soil particles can accumulate on rocks, allowing for some small plants to establish roots and grow.
What kind of animals live on leaves?
Hedgehogs, mice, maybe rats, small creatures like that ( If you're in the states then, Porcupine and Ground hogs can be included). Others include centipedes, millipedes, certain species of snake, ants, certain species of spider...mainly arthropods and other invertebrates.
What do plants need and how do they get it?
Plants need water to grow. Plants also need sunlight to grow. They get water from the natural rain fall or if they are taken care of it is provided by there owner. The sunlight is natural though some light can be provided from the lights inside of the home.
Why don't desert plants have leaves?
Leaves that have a small surface area lose less water.
What type of environment do plants with small leaves live in?
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.
Why do some plants have sticky leaves?
Some plants have sticky leaves to trap insects, which they then digest for nutrients that are lacking in their environment.
What are some examples of plants with simple leaves?
Some examples of plants with simple leaves include dandelions, sunflowers, and roses. These plants have leaves that are not divided into smaller leaflets and have a single, undivided blade.
Do all plants have leaves, or are there some exceptions to this common characteristic?
Not all plants have leaves. Some plants, like mosses and ferns, do not have true leaves but instead have structures that serve similar functions.
What are some examples of plants with compound leaves?
Some examples of plants with compound leaves include poison ivy, clover, and rose.
What are examples of lycophyta?
Examples of lycophytes include club mosses, spike mosses, and quillworts. These plants are small and typically have creeping or upright stems with small leaves. Lycophytes are considered some of the oldest vascular plants.
What are the plants with leaves of the same color?
Some plants with leaves of the same color include snake plants (Sansevieria), Chinese evergreen (Aglaonema), and spider plants (Chlorophytum comosum). These plants have consistent green leaves, although some variations within the species may exist.
What are some common characteristics of plants with leaves?
Plants with leaves typically have green, flat structures that are used for photosynthesis. They also have a network of veins for transporting water and nutrients. Leaves are usually attached to stems and can vary in size, shape, and texture. Additionally, many plants with leaves undergo a process called transpiration, where they release water vapor through small openings called stomata.
Do their leaves fall in winter?
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.
Can plants with long leaves be found in the desert?

True or false the two large groups of plants are those that have leaves and those that do not have leaves?
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.
