Leaves are designed to last only a short time so a secondary xylem and phloem supply is not needed. These chemicals offer a strong support system that is not needed in the leaves, just the trees.

What is the vasculuar tissue that transports water and minerals through a plant?

Xylem transports water up to the leaves.Water:Is absorbed from the soil through root hair cellsIs transported through the xylem vessels up the stem to the leaves.Evaporates from the leaves (transpiration)But the phloem transports nutrients to the leaves.


How are stems adapted for transporting food and water?

Stems have xylem tissue that conducts water from the soil to the leaves. they also have phloem tissue that conducts dissolved food from the leaves to the rest of the plant body

How are seed plants different from nonvascular plants?

Nonvascular plants dont have xylem and phloem, whereas seed plants have vascular bundles


What do plants have instead of a cardiovascular system?

Like animals, some plants do possess a vascular system that helps in transporting water and minerals from the soil to all parts of the plant and synthesized carbohydrates from leaves to all parts of the plant. These plants are called as vascular plants. The vascular plants bear two special types of tissues that are xylem tissues and phloem tissues that help in transportation within the plant.metabolism systems


What characterizes a bryophyte?

Bryophytes are non-vascular plants that lack true roots, stems, and leaves. They reproduce via spores and require a moist environment for fertilization to occur. They include mosses, liverworts, and hornworts.


Do strawberry plants have a vascular system?

Yes, strawberry plants have a vascular system composed of xylem and phloem. Xylem transports water and minerals from the roots to other parts of the plant, while phloem transports sugars and other nutrients produced in the leaves to other plant tissues.


How is the shape of xylem and phloem cells are related to their functions in plant?

Xylem cells are elongated and have thick walls to provide structural support and efficiently transport water and minerals throughout the plant. Phloem cells are more tube-like in structure to allow for the movement of sugars and other organic compounds produced during photosynthesis from the leaves to other parts of the plant. Their shapes are specialized to optimize their respective functions in the plant's vascular system.


What does water move up to the leaves?

Water moves up to the leaves through tiny tubes called xylem vessels in the plant's stem. This process is called transpiration and is driven by a combination of factors such as capillary action, cohesion and adhesion of water molecules, and evaporation of water through tiny openings in the leaves called stomata.


Do vascular plants have vessels?

vascular plants are plants that have vessels


How does water get to the leaves for photosynthesis to occur?

Water is transported upwards from the roots by a process called osmosis. This occurs in a layer of tissue called xylem consisting of elongated cells joined end to end. Xylem extends from the root all the way to the veins of a leaf. Downward transport of photosynthates and other substances such as hormones is achieved by a layer of tissue generally outside the xylem called the phloem. The order myrtales is an exception and has two layers of phloem both inside and outside the xylem.
