because most of them are made up of water. when the water evaporates out of them the cells deflate and become smaller as a result.
There are a number of reasons for leafs to reduce in size:
1. As in the above answer the leaf can decrease in size due to dessication of the leaf, and the plant if it does not receive sufficient water. This is the most directly measurable size change.
The other two decreases in leaf size are more subtle:
2. Plants also respond to external stimuli, such as light intensity. In areas of of high light intensity the size of new leaves can be reduced ; the reverse applies in low light conditions, where new leaves are larger to try and compensate for the lack of light.
3. Geographical location and climate; it is very common for exactly the same plant to look morphologically different if grown in different parts of the world under different climatic conditions.
The seed leaves, also known as cotyledons, shrink in size as the new plant germinates because their main function is to provide initial nutrients to support early growth. As the plant grows, it develops true leaves which take over the role of photosynthesis and nutrient production, causing the cotyledons to eventually wither and fall off.
A plant without leaves is called a "leafless plant."
A plant with finger-like leaves is called a palm plant.
The first two leaves on a bean plant are called cotyledon leaves. These leaves are part of the seed embryo and are different in shape and function compared to the plant's true leaves which will develop later.

Some plant leaves become wrinkled due to dehydration, lack of water, or nutrient deficiencies, which can cause the cells in the leaf to shrink and lose their turgidity. This results in the leaf appearing wrinkled or wilted.
It is called plasmolysis. The cytoplasm and vacuole shrink but cell wall remains the same.
they shrink and shrivel up
The nyctinastic movement which occur due to physical stimuli causes the leaves to rapidly droop or shrink.The leaves also shrink in response to darkness or daylight
The flower that is known to shrink in light is the "sensitive plant," or Mimosa pudica. This unique plant exhibits a rapid response to environmental stimuli, including light. When exposed to bright light, the leaves and flowers fold up and droop, appearing to shrink. This reaction is thought to be a defensive mechanism to protect against herbivores and environmental stress.
Leaves become floppy primarily due to a loss of turgor pressure, which is the result of insufficient water uptake. When a plant is under water stress or experiencing drought, the cells within the leaves lose water and shrink, causing the leaves to wilt. Additionally, factors like nutrient deficiencies or damage from pests can also contribute to the floppiness of leaves. This condition often signals that the plant needs care, such as watering or improved growing conditions.
Doctors hoped that the new drug would shrink cancer tumors without surgery. When they dry out, leaves can shrink and lose much of their weight.
the plant has to get chloraphill in the leaves can help a plant
Leaves are mainly responsible for photosynthesis in a plant.
A plant without leaves is called a "leafless plant."
yes they are a plant first leaves
