A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores. Compare with mitosis.
<h2>Answer:</h2>
The major importance of fingertips receptor is the sense of touch and recognition of things done by this sense.
<h3>Explanation:</h3>
- The first most thing we do with our hand is touch and recognizing things by this touch.
- This importance can be known by supposing that if we don't have these receptors, we will not able to recognize hard, soft even cold and hot.
- As if we encounter something hot which can harm our epidermal layer, our receptors immediately recognize it and pull the hand back by reflex action.
- So the most important receptors of our body are fingertips receptors.
Answer:
While plant cells have chloroplasts to photosynthesize, they also require ATP for cellular functions, and do use oxygen to break down some of the sugar they produce in order to generate that ATP. They need mitochondria for this.
In particular, at night when there is no light, plants undergo cellular respiration since there is no sunlight to photosynthesize.
They do, however, produce far more sugar and oxygen through photosynthesis than they use up in respiration.
Plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar :)
Explanation:
According to the chemiosmotic hypothesis, ATP is produced by due to the proton gradient created across the mitochondrial membrane. The essential components required for chemiosmosis are proton pump, proton gradient and ATP synthase. ATP synthase is an enzyme which helps in ATP synthesis. The enzyme ATP synthase has two part
F0 andF1.F0 is the part which transports protons across the membrane as a transmembrane channel while configuration changes in F1
activates the enzyme. They phosphorylate ADP i.e., add one more phosphorus group to the ADP and converts ADP(adenosine diphosphate) to ATP (adenosine triphosphate). The proton gradient developed across the membrane is the driving force of ATP synthase.
