What are 2 examples of modified leaves?
| Modification | Definition | Example |
|---|---|---|
| 1) Tendrils | The leaves are modified into slender wiry and coiled structures called leaf tendrils and support climbers to climb | Pisum Sativum |
| 2) Spines | The leaves modified into a pointed structure and usually protect them from herbivores. | Opuntia |
What are modified leaves on a flower?
Leaves or leaf parts may be modified to provide support. Tendrils and hooks are the most common of these modifications. In the flame lily (Gloriosa superba; Colchicaceae), the leaf tip of the blade elongates into a tendril and twines around other plants for support.
Which plant contains modified leaves?
Some plants have leaves that perform functions other than photosynthesis. While the tendrils of some plants are modifications to the stems and provide support for the plant, in other species, such as pea plants (Pisum sativum), the tendrils are modified leaves.
What are the 2 leaf types?
There are two basic forms of leaves that can be described considering the way the blade (or lamina) is divided. Leaves may be simple or compound. Simple and compound leaves: Leaves may be simple or compound. In simple leaves, the lamina is continuous.
What are the different types of modified leaves?
Tendrils A twisting, threadlike structure by which a twining plant (vine) grasps an object for support (modified leaf), and some tendrils are modified stems Spines Spines of cacti are actually leaves. Photosynthesis is carried out by the fleshy green stems. Storage leaves Most succulents have leaves modified-adapted for storing water.
Why are leaves modified in weak stemmed plants?
This kind of adaptation helps plants to conserve very limited supply of water and resist desiccation (drying up). 2. Leaf Tendrils: In weak- stemmed plants, leaf or a part of leaf gets modified into green threadlike structures called tendrils which help in climbing around the support.
What kind of plant has flowers, stem and leaves?
Angiosperms or flowering plants are differentiated into flowers, stem, roots, and leaves. These plants bear seeds that enclose the fruit. On the basis of seed type they can be classified into: Monocotyledonous – They have seeds with a single cotyledon.
Which is an example of a secondarily modified plant?
These are examples of shoots (including both the stem and leaves) that have become secondarily modified. Bulbs: These shoots are an adaptation for interrupted life….for existence in environments with a dormant season due to annual rainfall variations or to life in the temperate climates.
