Water transportation seems comparatively a simple phenomenon than how plants communicate with each other or the studies regarding whether they feel any pain. Because the transportation system seems so obvious and uninteresting there has been little research on this topic and there lie many other things that are still unknown. …

All viable seeds which have overcome dormancy (if any) either naturally or artifi­cially will readily germinate under suitable environmental conditions necessary for seed germination i.e., water, O2, temperature, and in some cases light. The seeds that just wait for suitable environmental conditions to germinate are said to be ‘quiescent’. In …

There are several factors that influence seed germination such as temperature, moisture, and seed dormancy. Temperature and moisture levels are fairly easy to explain but what is seed dormancy? All the viable seeds have the capacity to germinate if placed under suitable conditions necessary for germination. In certain plants, such …

In the case of some plants, even though they receive proper photoperiod, they do not flower. It means that apart from photoperiodism plants also require something for their subsequent flowering. But what is that? Not all plants flower when subjected to the correct photoperiod. The temperature has a profound effect …

Like all other living beings plants have to exchange gaseous molecules. Animals have noses that help them to breathe in and breathe out to exchange gases. But what about plants? How do plants breathe in and breathe out? Well, plants have stomata or tiny pores on their epidermis that help …

Ever wondered that your very own body might contain a motor like the one we use to run any machine? And it is not just any motor, but a motor recorded to be the world’s smallest one. This motor is commonly known as ATP synthase. Every one of the 50 …

We all know Darwin as the father of evolution. But we have almost no knowledge about Darwin the botanist. Our textbooks only taught us about how Darwin gave the evolution theory and what is evolution. Even the books included in our syllabus of schools and colleges for studying botany didn’t …

আমরা আমাদের আশেপাশের গাছগুলোকে ভাবি দৃষ্টিশূণ্য এক জীব। যাদের কাজ কেবল সালোকসংশ্লেষণ করা। তবে আমরা অনেকেই জানি না যে, আমাদের আশেপাশের গাছগুলো আসলে আমাদের দেখতে পায়। তারা তাদের আশেপাশের পরিবেশ পর্যবেক্ষণ করতে পারে। তারা দেখতে পারে আপনি লাল শার্ট পরেছেন নাকি নীল শার্ট? আপনার বাড়ির এক জায়গা থেকে তাদের অবস্থান …

We all have heard about summer or winter crops, but do we know why they are differentiated by seasons? Why are they specific for a certain season to sow and subsequent flowering? Well, the answer is for Photoperiodism. But what is this photoperiodism? If you want to know about photoperiodism, …

Buffers are aqueous systems that tend to resist changes in pH when small amounts of acid (H+) or (OH–) are added. A buffer system composes of a weak acid (the proton donor) and its conjugate base (the proton acceptor). A mixture of equal concentrations of acetic acid and acetate ion …
