Tooth Anatomy01:21

Tooth Anatomy

2.2K
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

Key Elements for Plant Nutrition

24.2K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Plant Hormones01:56

Plant Hormones

27.5K
Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

Tonicity in Plants00:53

Tonicity in Plants

59.8K
Tonicity describes the capacity of a cell to lose or gain water. It depends on the quantity of solute that does not penetrate the membrane. Tonicity delimits the magnitude and direction of osmosis and results in three possible scenarios that alter the volume of a cell: hypertonicity, hypotonicity, and isotonicity. Due to differences in structure and physiology, tonicity of plant cells is different from that of animal cells in some scenarios.

Plant Cell Wall02:43

Plant Cell Wall

60.3K
The plant cell wall gives plant cells shape, support, and protection. As a cell matures, its cell wall specializes according to the cell type. For example, the parenchyma cells of leaves possess only a thin, primary cell wall.

Area of Science:

  • Paleobotany
  • Computational Botany
  • Plant Taxonomy

Background:

  • Leaf teeth provide valuable systematic information for classifying fossil leaves.
  • Existing feature extraction methods lack standardized botanical definitions, hindering comparative analysis.
  • Automated plant leaf retrieval requires precise and consistent feature extraction.

Purpose of the Study:

  • To develop an image-based, botanically standardized method for describing and measuring leaf teeth.
  • To enable efficient and automatic retrieval of plant leaves from databases.
  • To provide standardized data for plant classification and evolutionary studies.

Main Methods:

  • Image preprocessing to create leaf binary maps.
  • Curvature Scale-Space (CSS) algorithm for corner detection and inflection point extraction.
  • Screening convex points for leaf tooth apex identification.
  • Measurement of leaf tooth characteristics (orders, spacing, number, sinus/tooth shape) based on botanical definitions.

Main Results:

  • The proposed method extracts standardized leaf tooth characteristics.
  • Classification using linear discriminant analysis and support vector machines demonstrated high accuracy.
  • The method's accuracy surpasses existing approaches.
