What attaches the leaf to the plant?

What attaches the leaf to the plant?

petiole
The petiole is a stalk that attaches a leaf to the plant stem.

What plant organ holds up the leaves of a plant?

stem
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.

Where does the leaf attach to the plant?

Structure of a Typical Leaf Some leaves are attached to the plant stem by a petiole. Leaves that do not have a petiole and are directly attached to the plant stem are called sessile leaves. Small green appendages usually found at the base of the petiole are known as stipules.

Which part of a leaf connects the leaf to the plant?

Also called the leaf stalk, the petiole is actually an extension of the leaf in certain plants. It is the structure that connects the leaf to the stem or trunk of most vascular plants. Far from being a simple attachment mechanism, the petiole is a key player in plant function.

Where a leaf attaches to the stem?

Parts of a stem: Leaves are attached to the plant stem at areas called nodes. An internode is the stem region between two nodes. The petiole is the stalk connecting the leaf to the stem.

Which of the following is the part of the plant where the leaf is attached to the stem?

Figure 1. Leaves are attached to the plant stem at areas called nodes. An internode is the stem region between two nodes. The petiole is the stalk connecting the leaf to the stem.

Which part attaches the leaf to the stem?

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 parts of the leaves?

Leaves have two main parts: The leaf blade and the Stalk or the petiole.

• The leaf blade: It is also called the lamina. It’s generally broad and flat.
• The petiole: It is the stalk-like structure which connects the leaf blade to the stem. The petiole has tiny tubes, that connect the veins on the leaf blade to the stem.

What are the organs of a flowering plant?

The organs are: 1. Roots 2. Stems 3. Leaves 4. Inflorescence 5. Flowers 6. Fruits 7. Seeds. Organ # 1. Roots: Roots differ from stems in the absence of nodes and leaves.

Which is part of a plant covers the leaves?

For example, dermal tissue covers the leaves, flowers, roots and stems of plants. Dermal tissue has several functions, including preventing the plant from losing too much water. Tissues work together in organs.

How are the leaves on a flowering plant arranged?

Arrangement of leaves on stem or Phyllotaxy (Fig. 21.9): Alternate – leaves occur single at each node and so arranged that a line drawn on the stem through the leaf bases will take a spiral course up the stem. Opposite – Two leaves at a node on opposite sides.

How are plant organs adapted to their function?

Every plant organ is adapted to its function. For example, leaves that are big and flat absorb plenty of sunlight for photosynthesis. Long roots keep a tree stable and take water from deep in the soil. Some plants have unusual adaptations. For example a potato is a swollen underground stem.
