Animal and Plant Cell Structure01:30

Animal and Plant Cell Structure

45.4K
Animal and plant cells not only differ in their structure, function, and mode of nutrition but also in how they reproduce, specialize, and organize into complex structures.
Cell Division
Though both plant and animal cells divide by mitosis (for non-gametic cells) and meiosis (for gametic cells), they differ in the specifics of this process. Unlike animal cells, plant cells lack centrosomes — an organelle responsible for organizing the spindle fibers and segregating the chromosomes during...

Plant Cells and Tissues

64.6K
Plant tissues are collections of similar cells performing related functions. Different plant tissues will have their own specialized roles and can be combined with other tissues to form organs such as flowers, fruit, stem, and leaves. Two major types of plant tissue include meristematic and permanent tissue.

Plant Tissues

8.4K
Plants are multicellular eukaryotes with tissue systems made of various cell types that carry out specific functions. Different tissues work together to perform a unique function and form an organ. Organs working together form organ systems. Vascular plants have two distinct organ systems: a shoot system and a root system. The shoot system consists of two portions: the vegetative (non-reproductive) parts of the plant, such as the leaves and the stems, and the reproductive parts of the plant,...

Cell Adhesion in Plants01:14

Cell Adhesion in Plants

3.1K
Plants have rigid cell walls that are made up of cell wall polysaccharides that mediate cell-cell adhesion. The primary cell walls of plants consist of two independent and interacting polysaccharide networks: a pectin matrix that embeds the second network comprising cellulose and hemicelluloses.
Pectins are complex heteropolymers mainly composed of negatively-charged α-D-glucopyranosyl uronic acid and some neutral glycosyl residues such as α-L-rhamnopyranose, α-L-arabinofuranose,...

Cell Motility through Blebbing01:16

Cell Motility through Blebbing

2.3K
Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including fibroblasts, immune cells, and single-celled organisms like the amoeba. The primary function of blebs is cell locomotion and apoptosis, but they are also found during necrosis and cell division. The life cycle of a bleb comprises an initiation phase followed by the expansion and retraction phases.

Cell Signaling in Plants01:25

Cell Signaling in Plants

6.0K
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

Area of Science:

  • Plant bioimaging
  • Cell biology
  • Quantitative analysis

Background:

  • Blobs and curves are common features in plant bioimages, representing diverse cellular components like proteins, nuclei, and cytoskeletal structures.
  • Analyzing the colocalisation of these features is crucial for understanding cellular processes.
  • Existing pixel-based colocalisation methods have limitations in accuracy and detail.

Purpose of the Study:

  • To present a quantitative, object-based alternative to traditional pixel-based colocalisation methods in plant bioimaging.
  • To enable precise quantification of colocalisation levels and inter-object distances.
  • To provide computational algorithms and experimental validation for enhanced bioimage analysis.

Main Methods:

  • Development of object-based computational algorithms for image analysis.
  • Application of algorithms to quantify colocalisation of "blobs with blobs" (e.g., protein-protein) and "blobs with curves" (e.g., organelle-cytoskeleton).
  • Integration of biological experiments to validate computational findings.

Main Results:

  • Demonstration of a clear quantitative alternative to pixel-based colocalisation analysis.
  • Successful quantification of colocalisation levels between different cellular objects.
  • Accurate measurement of distances between colocalised objects.

Conclusions:

  • Object-based methods provide a superior quantitative approach for analysing colocalisation in plant bioimaging.
  • This approach enhances the understanding of protein-protein and organelle-cytoskeleton interactions.
  • The study offers guidance for adopting computationally-based, quantified bioimage analysis.
