Transport In Plants Important Points or Short Notes
🌿Transport In Plants🌵
🍀Small distance transport >Diffusion
>Cytoplasmic streaming
>Active transport
🍀Translocation
>Transport over a long distance
>Through vascular tissues, xylem and phloem
🍀Multidirectional transport
>Organic compounds and mineral nutrients
🍀Unidirectional Transport
>Through xylem, water and minerals
🍀Diffusion
>Passive transport from higher to lower concentration
>Gaseous movement in plants
>Depends on the concentration gradient, permeability, temperature and pressure
🍀Facilitated diffusion
>Diffusion of hydrophilic moiety through a carrier protein
>Concentration gradient is required
>No expenditure of energy
🍀Aquaporins
>Water channels
🍀Symport
>Diffusion of two molecules in the same direction
🍀Antiport
>Diffusion of two molecules in the opposite direction
🍀Active transport
> Transport against the concentration gradient
>Uphill transport
>Expenditure of energy
🍀Osmosis
>Movement of water through a selectively permeable membrane from higher potential to lower potential until equilibrium is achieved
🍀Plasmolysis
>Water moves out of the cell leading to shrinkage
>Occurs in a hypertonic solution
🍀Flaccid
>When cells are kept in an isotonic solution, there is no net movement of water
🍀Turgid
>Cells become turgid when placed in a hypotonic solution
🍀Imbibition
>Absorption of water by solids and colloid
E.g. water absorption by seeds, dry wood
🍀Apoplastic path
>Cell wall and intercellular spaces
🍀Symplastic path
> System of interconnected protoplast
🍀Transpiration
>Loss of water through evaporation
🍀Guttation
>Exudation of xylem sap near the tip of grasses mostly at night due to root pressure
🍀Transpiration Pull
>Driving force for transportation of water upwards from roots to leaves
🍀Phloem Translocation
>Bidirectional, active process
Water, sucrose and other sugvars, amino acids, hormones

Last three months strategy to crack NEET 2021
The National Eligibility cum Entrance Test (NEET) will be on 1st August 2021. It is pivotal to utilize the last 3 months wisely for all candidates aspiring to crack NEET 2021. This is the time (race against time phrase meaning) when you all need to prepare a systematic roadmap. So here are some tips for your preparation in the last three months.
Relax and calm down
Stop thinking too much, hold on, take (take with a grain of salt idiom synonym) a breath and understand that a period of three months is sufficient to prepare for the target NEET exam. Stressing will just (just in case definition) make the situation difficult, so just recharge yourself with positive thoughts.
Action Plan and Time management
Study for at least 7-8 hours a day. Prepare a realistic day-wise timetable which includes proper planning on how to spend the whole day on which subject or topic. Start with making a list of topics that are still left to be done from the syllabus. After that prioritize the topics as per their frequency of occurrence in previous exams. Then start preparing for them. All of you know that 80% of the syllabus is going to be NCERT based. Even after reading NCERT two to three times, sometimes you might face difficulty in solving the questions. For this refer to some refreshers or other books for more and more practice. Solve as many MCQ questions as you can, related to one chapter after completing it. This way you will be able to point out your weak topics. Mark those and clear your basics.
TIP: You can achieve a super high score in Biology as it is theoretical, so please fully prepare it.
After you complete your syllabus
To reach this stage it might take you two months. Now do not start anything new, what is done is done. Here comes the time for REVISION. The topics which you marked as difficult or important, start revising them frequently. Keep on solving practice papers and last year’s papers to increase speed and accuracy.
Stay healthy, Stay focused
With the rising number of cases of COVID it is important for everyone to be safe and follow a healthy routine. Physical and mental strength both are going to affect your preparation, so have a balanced diet and take all precautions seriously. Take proper sleep and reduce or remove your unnecessary screen time. Stay focused on your goal and stay away from these distractions.
Stay away from negative comments
A lot of people around you build pressure on you by saying that the exam is going to be really difficult, the competition has increased, and we are not fully prepared and so on. Just simply ignore such comments that haunt you and demotivate you. Believe in your plan and hard work.
So, all the best. These three months are crucial, value the time and strive for your dream. Give your best so that you need not regret later for anything. Do not panic just go on with your preparation. I am sure you all will achieve NEET in 2021.
