Glycolysis takes in place in the cytoplasm of the eukaryotic cells. Question: Where does glycolysis occur in the cell? a) The cell membrane b) The Nucleus c) The cytoplasm ✔️ d) The mitochondria Answer: The cytoplasm What is glycolysis and where does it take place? Glycolysis is a metabolic pathway in which glucose breaks down into pyruvate (three-carbon compound) and released energy. In both eukaryotic and prokaryotic cells, glycolysis occurs in the cytoplasm. The cytoplasm is a thick fluid consist of water, salts, and proteins and enclosed by the cell membrane. Glycolysis is a cytoplasmic pathway that occurs in
No, plants cannot survive without oxygen. Similar to animals including humans, plants also require oxygen for cellular respiration. Why do plants require oxygen? The cellular respiration in plants requires oxygen to produce energy from sugar produced during photosynthesis. In this process, plants intake oxygen from the air through stomata and lenticels present in the leaves and stem respectively. This oxygen is used for aerobic respiration in the mitochondria of the cell. In aerobic respiration, the glucose molecule breaks down into water and carbon dioxide. C6H12O6 + 6O2 → 6CO2 + 6H2O + 32 ATP (energy) The carbon dioxide produced during respiration
“No, sunflowers do not face each other on cloudy days because they follow the circadian rhythm of heliotropism.” There is a misconception among a lot of people that on cloudy day’s sunflowers face each other to harness the mutual energy. But according to a scientific study conducted by the Department of Plant Biology, University of California, sunflowers follow the circadian rhythm of heliotropism even in the absence of light. Let’s try to understand how sunflower tracks sun during day and reset its position during night time. Heliotropism in sunflowers We all know that sunflower turns their face towards the
“Yes, all plants die but not due to old age. External conditions such as storms, drought, flood, cold weather, and wildfire can be responsible for their death.” We know that humans and animals die in their old age but have you ever wondered can trees die of old age? As we grow old, there is a decline in the functioning of our body system. Senescence limits our ability to repair tissues and cells. Due to weak immunity, we likelihood of suffering from various medical issues such as heart attacks, high or low blood pressure. But is this the same
Flowering plants can reproduce both by sexual and asexual means of reproduction. Sexual reproduction involves the fusion of male and female gametes which takes place through pollination by birds, insects, and water. This pollination causes the fertilization and the female ovules grow into seeds. Asexual reproduction can take place naturally as well as artificially. The natural vegetative propagation involves runners, tubers, plantlets, bulbs, corms, suckers, and keikis for asexual reproduction while there are several artificial methods such as cutting, grafting, and layering for asexual vegetative propagation. Many plants have the ability to propagate through both sexual and asexual reproduction.
