The Apoplast and Symplast

The Apoplast and Symplast

Plant growth depends on its ability to take up water and dissolved minerals from the soil. The root system of every plant is equipped with the necessary tissues to facilitate the entry of water and solutes. The plant tissues involved in the transport of water and minerals have two major compartments - the apoplast and the symplast. The apoplast includes everything outside the plasma membrane of living cells and consists of cell walls, extracellular spaces, xylem, phloem, and tracheids. The...

Surveys

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Summary

This summary is machine-generated.

In European Portuguese (EP), the liquid consonant /l/ shows velarisation across all syllable positions. Acoustic analysis reveals variations in velarisation based on syllable position and surrounding vowels.

Area of Science:

Phonetics
Acoustic Phonetics
Sociolinguistics

Background:

The velarisation of the liquid consonant /l/ is a debated topic in European Portuguese (EP).
Previous research has not fully clarified the acoustic correlates of /l/ velarisation across different phonetic contexts.
Understanding /l/ velarisation is crucial for phonological and dialectal studies of EP.

Purpose of the Study:

To investigate the controversial question of /l/ velarisation in European Portuguese.
To analyse acoustic data to clarify the velarisation behaviour of /l/ in various syllable positions.
To determine the influence of vowel context on /l/ velarisation.

Main Methods:

Acoustic analysis of first (F1), second (F2), and third (F3) formant frequencies and F2 slope.
Data collected from ten European Portuguese speakers.
Production of trisyllabic words with a paroxytone stress pattern, featuring /l/ in onset, complex onset, and coda positions.

Main Results:

Results indicate that /l/ in EP is produced on a velarisation continuum.
Consistently low F2 values suggest /l/ is velarised in all syllable positions.
Variations in F1 and F3 reveal degrees of velarisation influenced by syllable position and vowel context.

Conclusions:

The study confirms that /l/ velarisation in EP is variable and context-dependent.
Acoustic measures, including formant frequencies and F2 slope, are essential for a comprehensive understanding of /l/ velarisation.
Findings contribute to a nuanced understanding of European Portuguese phonetics and phonology.
