Phloem

Some plant species are more resistant to phloem necrosis than others, due to differences in their natural defenses against pathogens.

In some countries, phloem fibers are an important export commodity.

Sieve cells are the primary cells of phloem tissue and responsible for the transport of sugars in plants.

The phloem in the roots of the plant transports sugars from the leaves to the rest of the plant.

The phloem in the roots plays an important role in the plant's overall health.

Phloem transport involves the movement of sucrose.

The symptoms of phloem necrosis can vary depending on the plant species and the pathogen involved.

Some species of ants have developed a mutualistic relationship with aphids and protect them in exchange for access to the phloem sap they produce.

Trees use the phloem layer to transport water and other nutrients from the roots to the leaves.

Phloem necrosis can be caused by a number of different pathogens, including viruses and bacteria.

The phloem provides an important food source for many species of insects.

Phloem damage caused by herbicides can significantly affect plant growth.

The phloem elements play an important role in the communication between different parts of the plant, allowing for coordinated responses to internal and external stimuli.

Some indigenous people still use phloem fibers to make their traditional clothes.

Phloem loading occurs primarily in the leaves of the plant.

The grapevine suffered from phloem necrosis caused by a bacterial disease.

The differentiation of phloem elements from precursor cells is controlled by specific gene regulatory networks.

The phloem in the roots of plants is responsible for the transport of organic compounds from the leaves to the roots.

The phloem layer is responsible for carrying sugars and other nutrients from the leaves to the rest of the tree.

The phloem is a living tissue in plants that transports food and nutrients from the leaves to other parts of the plant.

The farmer was worried about his crops because he noticed signs of phloem necrosis.

The phloem of the sweet potato stores carbohydrates that are used to support the plant during times of stress.

The phloem cells in the roots of the plant are smaller in diameter than those in the stems.

The phloem tissue in plants is located in the stem and roots, and also in the leaves and other parts of the plant.

Phloem necrosis can have devastating effects on the overall health of a plant, as it disrupts the transport of essential nutrients.

The cause of phloem necrosis is often a virus.

The phloem elements are closely associated with other plant tissues, such as the mesophyll cells in the leaves and the cambium in the stem.

The phloem in the roots is protected by the bark of the plant.

The phloem necrosis in the fruit trees was caused by a bacterial infection.

The phloem cells play an important role in the plant's ability to heal itself.

The phloem fibers play an important role in strengthening the stem of the plant and supporting the weight of the leaves and flowers.

The phloem cells repair damage caused by herbivores or other animals that feed on the plant.

The phloem tissue in plants is made up of different types of cells, including the repair cells known as phloem.

The tree is covered in sticky phloem that has been excreted by the aphids.

The quality and quantity of the phloem sap are affected by many factors.

The farmer was worried about the damage caused by the aphids' feeding on the phloem.

The phloem produced by the aphids is a sticky substance that can be difficult to remove from plants.

The phloem is a valuable food source for bees and other insects.

The phloem plays a crucial role in the process of translocation in plants.

Damage to the phloem can affect a plant's growth and overall health.

The phloem is found in all vascular plants, including ferns and gymnosperms.

Aphids and other sap-sucking insects can damage the phloem, disrupting nutrient transport in the plant.

Damage to the phloem layer can be caused by a variety of factors, including disease, insects, and physical trauma.

The phloem layer can be identified by its greenish color and fibrous texture.

The phloem loading process is mediated by specific transporter proteins.

The phloem loading process is regulated by various enzymes.

The function of phloem is to transport sucrose, amino acids, and other organic compounds from photosynthetic cells to non-photosynthetic cells in plants.

The phloem is made up of several different types of cells, including companion cells, sieve tube elements, and parenchyma cells.

The phloem loading process requires energy from the plant.

The phloem sap plays an important role in the plant's nutrient transport system.
