The document discusses the transport system in plants. Xylem tissue carries water and dissolved minerals absorbed by the roots up through the stem and to the leaves. Phloem tissue carries glucose made in the leaves throughout the rest of the plant. Transpiration is the process by which plants lose water through their leaves. Water is carried through the xylem and transpired through stomata, tiny pores in the leaves guarded by guard cells, which causes more water to be drawn up from the roots to replace what is lost.

Transportation in plants
Plants have specialized transport systems to move water, minerals, and food throughout the plant. Xylem tissue transports water and minerals absorbed by the roots upward through the stem and to the leaves. Phloem tissue transports food in the form of sugars made through photosynthesis in the leaves to all parts of the plant where it is needed. Water is transported against gravity through the xylem by root pressure in some plants and transpiration pull in tall trees. Phloem transports food through an active process using energy from ATP to power movement of sugars to areas of growth and storage.

It discusses how water and nutrients are transported from the roots to the leaves through xylem tissue, and how photosynthates are transported from the leaves to other plant parts through phloem tissue. The key transport mechanisms discussed are root pressure, capillary action, and transpiration pull. Transpiration pull is driven by transpiration from the leaves and is the primary force that draws water up the xylem. Environmental factors like temperature, light, and humidity can affect the rate of transpiration.
Cambridge AS Biology plant revision
Plants need transport systems to move water, minerals, and sugars throughout their tissues since roots absorb water and minerals from the soil while leaves produce sugars through photosynthesis. Xylem tissue transports water and minerals upward from the roots to the leaves, having dead cells with thick lignified walls that form continuous tubes. Phloem tissue transports sugars downward from the leaves to all parts of the plant using living sieve tube cells and companion cells. Transport occurs via mass flow driven by water potential gradients between sources and sinks.

Trasport in plants ppt
Plants need transport systems to move water, minerals, and food throughout their bodies. Water and minerals are transported from the roots to the leaves through xylem vessels. Energy from photosynthesis in the leaves is transported throughout the plant as food through phloem sieve tubes. Transpiration pull and root pressure work together to drive the upward movement of water through the xylem. Translocation of food through the phloem utilizes energy to actively transport sugars and other materials both upward and downward according to the plant's needs.

Plant transport ppt
This document discusses plant transport mechanisms including passive and active transport. It describes the key plant tissues involved - xylem and phloem. Xylem transports water and minerals from roots to shoots, while phloem transports sugars from leaves to other plant parts. Water potential, determined by solute concentration and pressure, drives the movement of water and solutes within plant cells and tissues.
06 vascular tissue
Vascular plants have vascular tissue composed of xylem and phloem that transport water, nutrients and sugars between roots, stems, and leaves. Xylem transports water and minerals up from the roots through hollow tubes called tracheids and vessel elements. Phloem transports sugars made in leaves to all plant parts through sieve tube elements and companion cells. Substances move through vascular tissue via diffusion, osmosis, and active or passive transport across cell membranes according to concentration gradients.
Plant transport
This document provides an overview of resource acquisition and transport in vascular plants. It describes the three scales of transport as (1) individual cells, (2) short-distance transport between tissues and organs, and (3) long-distance transport throughout the plant via xylem and phloem. Key mechanisms discussed include the proton pump, osmosis, water potential, and co-transport. Long-distance transport occurs via transpiration pull, where water is pulled up from the roots to the leaves through the xylem due to transpiration and cohesion-tension.
Transport in flowering plants (self created)
This document discusses the structure and function of xylem in flowering plants. It aims to explain how water is transported from roots to leaves through vascular bundles, which contain xylem and phloem.

Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.

Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

Transport system in plants
- 2. Transport Tissue in Plants XYLEM PHLOEM Carry water and dissolved minerals absorbed by roots – stem – leaves. Carry glucose from leaves to all parts of the plants
- 6. TRANSPIRATION • Process which a plant loses water (water vapour) from leaves to environment through stomata. • More stomata are found on lower epidermis – to prevent from losing excess water.
- 7. • A stoma- tiny pore between a pair of cells known as guard cells. • Guard cells- control the opening and closing of the stoma. • Gases in and out of the leaf through stoma during photosynthesis and respiration.
- 8. Role of transpiration in transport • As water is lost or used up by the plants, more water is sucked up from xylem in leaves, stem and roots. • It is a continuous process.
