Q. What 2 things does the stem carry up to the top of the plant from the roots?
Plants have tubes that run through their stems and roots. These tubes carry water, minerals, and sugars. There are two types of tubes: xylem and phloem. The xylem and phloem connect the top and bottom of the plant.
Q. Which cells are responsible for carrying water out of the root and up the plant?
Plants have tissues to transport water, nutrients and minerals. Xylem transports water and mineral salts from the roots up to other parts of the plant, while phloem transports sucrose and amino acids between the leaves and other parts of the plant.
Q. Where is the apical meristem located?
Apical meristems, which are located at the tips of shoots and roots in all vascular plants, give rise to three types of primary meristems, which in turn produce the mature primary tissues of the plant.
Q. Do stems have apical meristems?
Meristematic tissues are found in many locations, including near the tips of roots and stems (apical meristems), in the buds and nodes of stems, in the cambium between the xylem and phloem in dicotyledonous trees and shrubs, under the epidermis of dicotyledonous trees and shrubs (cork cambium), and in the pericycle of …
Q. What is the meaning of apical growth?
Growth promoted by the apical Meristem region of plants (at the root and shoot tips).
Q. What is the meaning of apical?
Apical: The adjective for apex, the tip of a pyramidal or rounded structure, such as the lung or the heart. For example, an apical lung tumor is a tumor located at the top of the lung.
Q. What is another name for apical meristem?
In vascular plants, the apical meristem gives rise to the protoderm, the procambium, and the ground meristem. The protoderm, in turn, develops into epidermis, the procambium, chiefly into primary vascular tissues, and the ground meristem, into ground tissues. Also called: apical meristematic tissue.
Q. What is apical cell division?
An apical cell is a cell that divides repeatedly to form new cells. An apical cell has a front face and up to three rear faces. All cell division takes place along the rear faces and never along the front face.
Q. What is the apical side of a cell?
The basal side of the cell is the side that faces the basement membrane, i.e. the connective tissue layer the cell lives on. The apical side is the side that faces the opposite direction, usually towards the lumen (inside) of a tube.
Q. What is apical and basal surface?
The bottom edge of the epithelial tissue next to the basement membrane is the basal surface. In contrast, the edge of the epithelial tissue facing the lumen or the external environment is called the apical surface.
Q. Does the basal side face the lumen?
Often one compartment is an external space or lumen of a tube and the other is the rest of a tissue or organ. The apical side of the epithelial cells faces the external space or lumen and the basal side faces the rest of the organ.
Q. What does apical surface mean?
Term. apical surface. Definition. surface of epithelial cell that is exposed to the body exterior or to the cavity of an internal organ. -“free surface”
Q. What is the purpose of the cilia at the apical surface?
They work, for instance, to keep the airways clear of mucus and dirt, allowing us to breathe easily and without irritation. They also help propel sperm. Primary cilia appear typically as single appendages microtubules on the apical surface of cells and lack the central pair of microtubules (e.g. in kidney tubules).
