Meristems and Plant Growth

49.7K
Plants grow throughout their lives; this is called indeterminate growth, and it distinguishes plants from most animals. Although certain parts of plants stop growing (e.g., leaves and flowers), others grow continuously—like roots and stems.

Plant Hormones01:56

Plant Hormones

27.7K
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.

Plant Cell Wall02:43

Plant Cell Wall

60.6K
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.

Sustainable Development

15.2K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Psychodynamic Perspectives on Personality01:27

Psychodynamic Perspectives on Personality

1.6K
The psychodynamic perspective in psychology asserts that most personality functions operate unconsciously, outside of awareness. This means that the motives and emotions driving behavior often remain hidden, automatically buried in the unconscious mind as a defense mechanism to shield us from psychological distress. According to this theory, the unconscious mind contains thoughts, memories, and emotions that are too disturbing to face directly.
Psychodynamic theorists argue that unconscious...

Plant Tissue Culture

40.8K
Plant tissue culture is widely used in both primary and applied science. Applications range from plant development studies to functional gene studies, crop improvement, commercial micropropagation, virus elimination, and conservation of rare species.

Area of Science:

  • Nanotechnology
  • Plant Science
  • Environmental Science

Background:

  • Engineered nanomaterials (ENMs) are increasingly used in agriculture for crop improvement.
  • ENMs exhibit diverse impacts on plants, including growth enhancement, inhibition, and toxicity.
  • Mechanisms of ENM translocation, growth response, and stress modulation in plants require deeper investigation.

Purpose of the Study:

  • To provide a comprehensive review of ENMs in plant systems.
  • To critically analyze the positive, negative, and null impacts of ENMs on plant physiology and molecular processes.
  • To discuss ENM uptake, translocation, and their effects on plant growth, development, and stress responses.

Main Methods:

  • Literature review of recent research on ENMs in plants.
  • Analysis of studies detailing ENM effects on plant physiology and molecular pathways.
  • Discussion of species-specific responses and underlying interaction mechanisms.

Main Results:

  • ENM effects on plants are species-specific and variable.
  • ENM exposure can lead to enhanced crop yield, altered gene expression (including microRNAs), and phytotoxicity.
  • Plants respond to ENMs by activating antioxidant defense systems and free radical scavenging.

Conclusions:

  • Understanding ENM-plant interactions, including uptake and molecular effects, is crucial for agricultural applications.
  • Judicious use of ENMs holds potential for revolutionizing crop production through enhanced yield and stress resistance.
  • Further research into ENM-plant cell interactions and miRNA modulation is warranted.
