Tracheids:
1. These are xylem elements found in all types of vascular plants.
2. These are single cells with tapering ends, hence are not syncytes.
3. Tracheids are shorter in length.
Vessels:
1. These are also xylem elements but restricted to angiosperms only .
2. A vessel is formed by several cells arranged end to end and dissolved cross walls, hence is a syncyte.
3. Vessels are much longer than tracheids and are main component for water conduction.
Tracheids and vessels together make up the xylem tissue in vascular plants. Xylem is responsible for transporting water and minerals throughout the plant. Tracheids are long, slender cells that conduct water and provide structural support, while vessels are shorter and wider, facilitating faster water movement.

What tissue moves water up from plants roots?
The tissue responsible for moving water up from the plant roots is called xylem. Xylem consists of specialized cells called tracheids and vessel elements that form a network of interconnected tubes. These tubes allow water to be transported upwards through the plant, from the roots to the leaves.
Water and minerals flow up through the?
Water and minerals flow up through the roots of plants into the stem and leaves through a process known as transpiration. This process involves water being absorbed by the roots and then transported upward through the xylem, driven by evaporation and capillary action. Minerals are absorbed along with the water to support the plant's growth and metabolism.
What are phloem vessels made of?
Phloem vessels are made of living cells, including sieve tube elements and companion cells. Sieve tube elements are elongated cells that form the main transport conduits, while companion cells provide metabolic support to the sieve tube elements. Together, these two types of cells make up the structure of phloem vessels.
What are a group of tisses working together?
They come together to make up organs
What makes up 20 percent of the dermis?
Collagen fibers and blood vessels make up 20 percent of the dermis. Collagen provides structural support and elasticity to the skin, while blood vessels help in nourishing the skin cells and regulating temperature.
In angiosperms xylem consists of tracheids and?
vessels. Tracheids are long, thin cells that transport water and nutrients, while vessels are shorter, wider cells that facilitate efficient water transport. Together, they make up the xylem tissue that plays a crucial role in conducting water and minerals throughout the plant.
How many types of elements together make up the xylem tissue?
There are four main types of elements that make up xylem tissue: vessel elements, tracheids, fibers, and parenchyma cells. These elements work together to transport water and minerals from the roots to the rest of the plant.
What two cell types make up xylem amd phloem?
Xylem is composed of tracheary elements (such as vessels and tracheids) and fibers. Phloem is composed of sieve tube elements and companion cells.
What key cells are in xylem?
The key cells in xylem are tracheids and vessel elements in angiosperms, and tracheids and vessel elements, along with fibers and parenchyma cells, in gymnosperms. These cells are responsible for the transportation of water and minerals from the roots to the rest of the plant.
What are 2 structures which make up of xylem?
Xylem may be made up of tracheids and vessel elements.
What are the features of xylem?
Xylem is a type of vascular tissue responsible for transporting water and nutrients from the roots to the rest of the plant. It is composed of tracheids, vessel elements, fibers, and parenchyma cells. Xylem also provides structural support to the plant.
What are the xylem cells that most of a tree's wood is made up of?
The xylem cells that make up most of a tree's wood are called tracheids and vessel elements. Tracheids are long, thin cells with tapered ends that transport water and minerals vertically within the tree. Vessel elements are wider, shorter cells that are stacked end-to-end to form vessels for efficient water transport.
Why is the dermis elastic and spongy?
The dermis, the layer just below the epidermis, is made up of collagen, elastin fibers, and blood vessels. Together they make your skin spongy and plump.
Vessels and the heart make up what?
Cardiovascular system, or circulatory system
What two things make up the circulatory system?
heart and blood vessels
What tissue moves water up from plants roots?
The tissue responsible for moving water up from the plant roots is called xylem. Xylem consists of specialized cells called tracheids and vessel elements that form a network of interconnected tubes. These tubes allow water to be transported upwards through the plant, from the roots to the leaves.
What are the three parts that make up the cardiovascular system?
Your heart, blood and blood vessels.
