Also asked, what does it mean when a leaf is lobed?

Leaves with small, marginal teeth or serrations are generally regarded as simple. The term entire refers leaves without any toothing or division. Lobed: show all. Leaves with distinct protrusions, either rounded or pointed. Pinnately lobed leaves have the lobes arranged on either side of a central axis like a feather.

What trees have opposite leaves?

Very few trees in our landscapes and forests have opposite branching. The predominant types are Maple, Ash, Dogwood and Horsechestnut. A simple phrase to remember when identifying trees with opposite branching is to use the acronym *MAD Horse* representing Maple, Ash, Dogwood & Horsechestnut.

What trees have alternate leaves?

Examples of trees and shrubs with an opposite leaf arrangement:

  • Ash trees (Fraxinus spp.). The ash tree has a compound leaf, which is also composed of leaflets arranged oppositely.
  • Fringe tree (Chionanthus virginicus)
  • Maple trees (Acer spp.)
  • Olive trees (Olea spp.)
  • Viburnums (Viburnum spp.)

    What is lobe of the brain?

    What organs have lobes?

    Examples of lobes

  • The four lobes of the human cerebral cortex. the frontal lobe.
  • The three lobes of the human cerebellum. the flocculonodular lobe.
  • The two lobes of the thymus.
  • The two and three lobes of the lungs. Left lung: superior and inferior.
  • The four lobes of the liver. Left lobe of liver.
  • The renal lobes of the kidney.
  • What are the lobes?

    The cerebral cortex can be divided into four sections, which are known as lobes (see image). The frontal lobe, parietal lobe, occipital lobe, and temporal lobe have been associated with different functions ranging from reasoning to auditory perception.

    What is a lobed nucleus?

    Granulocytes are a category of white blood cells characterized by the presence of granules in their cytoplasm. They are also called polymorphonuclear leukocytes (PMN, PML, or PMNL) because of the varying shapes of the nucleus, which is usually lobed into three segments.

    What is a multi lobed nucleus?

    The lobes in a nucleus are the DNA of certain immune cells, which have packaged their genetic material in multiple spheres instead of one big sphere. These types of nuclei are called lobular nuclei. They are found in the following types of immune cells: neutrophils, eosinophils, basophils and mast cells.

    What is a lobe lung?

    The right lung has both more lobes and segments than the left. It is divided into three lobes, an upper, middle, and a lower, by two fissures, one oblique and one horizontal. The upper, horizontal fissure, separates the upper from the middle lobe.

    What is a lobe in chemistry?

    Illustrated Glossary of Organic Chemistry – Orbital lobe. Orbital lobe (lobe): A section of orbital bordered by one or more orbital nodes. The π orbital of ethylene has two orbital lobes (one shown in the red and the other in blue), and one orbital node (the plane which contains the atoms).

    What is an antenna lobe?

    In a radio antenna’s radiation pattern, the main lobe, or main beam is the lobe containing the maximum power. This is the lobe that exhibits the greatest field strength. The other lobes are called “sidelobes”, and usually represent unwanted radiation in undesired directions.

    What is a lobe in medical terms?

    Medical Definition of Lobe. A lobe may be demarcated from the rest of the organ by a fissure (crack), sulcus (groove), connective tissue or simply by its shape. For example, there are the frontal, parietal, temporal, and occipital lobes of the brain.

    What are the lobes of the lung?

    The right lung is divided by the oblique fissure, which separates the inferior lobe from the middle and superior lobes, and the horizontal fissure, which separates the superior from the middle lobe. The human left lung is divided into two lobes, an upper and a lower, by the oblique fissure.

    What are the lobes of the lungs?

    Middle Lobe Lung. Medically reviewed by Healthline Medical Team on March 18, 2015. The lung consists of five lobes. The left lung has a superior and inferior lobe, while the right lung has superior, middle, and inferior lobes. Thin walls of tissue called fissures separate the different lobes.

    Why do we have 3 lobes in the right lung?

    The left lung is smaller because of the space taken up by the heart (see diaphragm for an image of this). Each lung is separated into lobes branching off the main bronchus; the right lung has three lobes, while the left has only two lobes. The lungs are “stuck” to the inside of the thorax, also by surface tension.

    Which lung is smaller and why?

    Each lung is divided into upper and lower lobes. The right lung is larger and heavier than the left lung, which is somewhat smaller in size because of the position of the heart. The upper lobe of the right lung contains another triangular subdivision known as the middle lobe.

    Which lung is longer?

    The right lung is larger than left lung, due to the heart being located slightly to the left (even though it is shorter due to upward compression by liver). The left lung is made up of 2 lobes while right is made up of 3 lobes.

    Can you live with one lung?

    Living with one lung doesn’t usually affect everyday tasks or life expectancy, though a person with one lung wouldn’t be able to exercise as strenuously as a healthy person with two lungs, said Dr. Len Horovitz, a pulmonologist at Lenox Hill Hospital in New York City.

    What do the lungs do?

    The lungs and respiratory system allow oxygen in the air to be taken into the body, while also enabling the body to get rid of carbon dioxide in the air breathed out. Respiration is the term for the exchange of oxygen from the environment for carbon dioxide from the body’s cells.
