- Q. Why do Mosses lack vascular tissue?
- vascular plants. Plants that have tubes inside of them to transport liquid.
- nonvascular plants. Plants that DO NOT contain tubelike structures and use other ways to move water and substances.
- mosses.
- liverworts.
- hornworts.
- seedless vascular plants.
- ferns.
- club mosses.
Q. What are the small tube-like structures?
Blood vessels are small tube-like structures through which blood circulates throughout the human body. The blood vessels transport oxygen and nutrients to the tissues and organs and remove carbon dioxide and waste away from the tissues and organs.
| A | B |
|---|---|
| flowering plant | a vascular plant that produces seeds inside a flower |
| moss | a small,nonvascular plant that has both stems and leaves but no roots |
| nonvascular plant | plants that don’t have tubelike cells in their stems and leaves |
| phloem | cells that carry food that is made in the leaves to all parts of the plant |
Q. What is the main function of vascular tissues?
The vascular tissues of plants, which are composed of specialized conducting tissues, xylem and phloem, form continuous systems through the plant body and provide transport pathways for water, nutrients, and signaling molecules and support a plant body against mechanical stresses.
Q. How do u appreciate the function of vascular tissue?
Vascular tissues are also known as conductive tissue, they help to conduct water and other substances from one part of the plant body to another. For example, ferns contain two types of vascular tissue, xylem and phloem, which move nutrients throughout the plant and allow them to grow tall.
Q. Which of the following best describes vascular tissue?
Vascular tissue is a complex conducting tissue, formed of more than one cell type, found in vascular plants. The primary components of vascular tissue are the xylem and phloem. These two tissues transport fluid and nutrients internally.
Q. What are the two types of vascular tissue found in vascular plants How do they differ?
There are two different types of vascular tissues, called xylem and phloem. Xylem is vascular tissue that transports water and dissolved minerals from roots to stems and leaves. This type of tissue consists of dead cells that lack end walls between adjacent cells.
Q. Does Moss have vascular tissue?
Mosses and liverworts are lumped together as bryophytes, plants lacking true vascular tissues, and sharing a number of other primitive traits. They also lack true stems, roots, or leaves, though they have cells that perform these general functions.
Q. Can plants survive without vascular tissue?
Plants that lack vascular tissue, which is formed of specialized cells for the transport of water and nutrients, are referred to as non-vascular plants or bryophytes. Non-vascular embryophytes probably appeared early in land plant evolution and are all seedless. These plants include liverworts, mosses, and hornworts.
Q. Why can’t a moss grow to be as tall as plants that have vascular tissue?
Moss plants are small, but ferns can grow as tall as small trees. Vascualr tissue supports a tall plant and carries water and nutrients from, the soil the plant’s upper region. Thus ferns, which have vascular tissue, can grow tall, whereas mosses, which lack vasucualr tissue cannot grow tall.
Q. What lacks vascular tissue?
Most bryophytes are small. They not only lack vascular tissues; they also lack true leaves, seeds, and flowers….
| Term | Definition |
|---|---|
| bryophyte | type of plant that lacks vascular tissues, such as a liverwort, hornwort, or moss. |
Q. What are the three types of non vascular plants?
Nonvascular plants (often referred to collectively as the bryophytes) include three groups: the mosses (Bryophyta), approximately 15,000 species; liverworts (Hepaticophyta), approximately 7500 species; and hornworts (Anthocerophyta), approximately 250 species (Table 1).
Q. Why do Mosses lack vascular tissue?
Some mosses have simple water and food conduction‐type cells (but these are not the same as the xylem and phloem tissues of vascular plants). They have no lignified cell walls (like wood) for strength, so the plants remain small. Neither do they have leaves, stems, or roots.
