What is a modified stem of a plant?
A rhizome is a modified stem that grows horizontally underground; it has nodes and internodes. Vertical shoots may arise from the buds on the rhizome of some plants, such as ginger and ferns.
What are the 5 types of modified stems?
Modified stems can be categorized into three types:
- Underground – Rhizome, Bulb, Corm, Tuber.
- Subaerial – Runner, Sucker, Offsets, Stolon.
- Aerial – Tendrils, Thorn, Bulbils, Cladode, Phylloclade.
What are the 4 modified stems?
Modified stems that grow horizontally underground are either rhizomes, from which vertical shoots grow, or fleshier, food-storing corms. Aerial modifications of stems include tendrils, thorns, bulbils, and cladodes..
What types of stems are in plants?
Underground stem, Aerial stem, and subaerial stem are three different types of Stem. A stem has many important functions it performs other than letting you climb a tree. Let us take an in-depth look at the stem of plants.
What are examples of modified leaves?
Modifications of Leaves (Explained With Diagram)
- 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:
- Phyllode:
- Insect Catching Leaves:
What are two examples of modified leaves?
| Modification | Definition | Example |
|---|---|---|
| 4) Storage leaves | Leaves become fleshy due to storage of water and food material. | Aloe |
| 5) Cotyledons | The mature embryo shows either one or two cotyledons. | Angiosperms and gymnosperms |
| 6) Leaf bladders | Some of the leaves of aquatic plants modified into leaf bladders to trap small insects. | Utricularia |
Is Onion a modified stem?
The onion bulb is a modified stem because it consists of large numbers of fleshy scales leaves. At the base of the onion the root appears as a thread like structure.
What are examples of stems?
Examples of food-storing stems include such specialized forms as tubers, rhizomes, and corms and the woody stems of trees and shrubs. Water storage is developed to a high degree in the stems of cacti, and all green stems are capable of photosynthesis.
Is onion a modified stem?
Another example of modified stems is rhizomes, which are brownish, large, root-like horizontal stems that grow just below or along the soil surface. These store food and, because they have buds, can spread to form new plants. The potato plant has rhizomes which end in large structures specialized for storage called tubers.
What are the functions of the stem in a plant?
The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transport these products from the leaves to other parts of the plant, including the roots.
Why is a stem so important for a plant?
The stem of the plant connects the roots to the leaves, helping to transport absorbed water and minerals to different parts of the plant. It also helps to transport the products of photosynthesis, namely sugars, from the leaves to the rest of the plant.
Why is stem helpful in a plant?
Stems have a number of defensive properties to help protect a plant from infection and being eaten by insects, birds and mammals. They can also be an important site of photosynthesis for many plants.
