- Storage Leaves: Some plants of xerophytic habitats and members of the family Crassulaceae generally have highly thickened and succulent leaves with water storage tissue.
- Leaf Tendrils:
- Leaf-spines:
- Scale-leaves:
- Leaflet Hooks:
- Leaf Roots:

What are two leaf modifications and their functions?
The two leaf modifications are spines and tendrils. are a plant organ that may be derived from a whole leaf or terminal leaflets. They are used to support and anchor vining stems like in peas and grapes.
What are parts of leaves?
Each leaf typically has a leaf blade ( lamina ), stipules, a midrib, and a margin. Some leaves have a petiole, which attaches the leaf to the stem; leaves that do not have petioles are directly attached to the plant stem and are called sessile leaves.
What are the 5 types of leaves?
There are two different types of leaves – simples leaves and compound leaves. The other types of leaves include acicular, linear, lanceolate, orbicular, elliptical, oblique, centric cordate, etc. They perform the function of photosynthesis and help in the removal of excess water from the aerial parts of the plant.
What is modification of parts of plants?
Modified parts means the part has been specialised to perform other functions also. For example: Roots of certain plants have been modified to perform functions such as storage along with other functions such as water absorption.
What are the 7 parts of a leaf?

What are the 5 parts of a leaf?
Petiole, leaf base, lamina, leaf apex, and leaf margin are the external parts of a leaf.
What do you mean by modified leaves?
Whole leaves or parts of leaves are often modified for special functions, such as for climbing and substrate attachment, storage, protection against predation or climatic conditions, or trapping and digesting insect prey.
Why do leaves modify?
Leaves can be modified in the form of spines that reduce water loss and also act as a defence. Some are modified into tendrils to provide support to the plant. Some leaves are thick that help in water storage. Some are modified to catch and digest insects.
What are two examples of modified leaves?
Plants may change either the structure of the leaves, the color (to attract insects), or may add spines or thorns to protect itself. Examples of plants with modified leaves are: Nepenthes, Drossera, Tendrils, Venus fly-trap, sundew, poinsettias, and pitcher plants.
What are modified leaves?
A modified leaf is an adaptation of plant meant for its own survival due to its environmental stress. When a leaf performs functions other than photosynthesis and transpiration, structural changes may occur.
What does leaf falling mean?
Definition of falling leaf. : an aerobatic flight maneuver in which an airplane is allowed to stall and is then slipped successively to the right and left, the nose being held to point in the same direction throughout.
What is a leaf diagram?
A Stem-and-Leaf Diagram is a way of organising a list of numerical data. The stem consists of the first part of the number. The leaves consist of the last digit of the number. The diagram always has a Key, which normally uses the first entry in the table and describes what the entry means.
