Vacuoles are important plant organelles which help in osmoregulation. Hence some ions are actively concentrated to maintain their balance and the fluidity of the cytoplasm. Giardia lamblia is a protozoan parasite with two unequal nuclei in its cell.

Plasticity refers to the environment in which plants follow different pathways in response to environment or phases of life forming different kinds of structures. The environmental plasticity is best seen in emergent hydrophytes,eg., Ranunculus flabellaris(buttercup).

And osmole is defined as the no. Of moles oc solute that contribute to osmotic pressure.....

Yakshi ? 7 years ago

As it is cleared by its name.....osmole + molarity...as we know molarity is the concentration of solution expressed as no. of moles of solute per liter of solution.......so it is the no. Of osmoles (as a solute) per liter of a solution

Gaurav Seth 7 years ago

Osmolarity is a unit which is used to measure solute concentration. It is also referred as osmotic concentration. Osmolarity is measured in the terms of osmoles of solute present in one liter of solution (Osm/L). Thus, it tells about osmotic pressure contributed by number of moles of a compound of  a solution.

Glycolysis is the primary stage of cellular respiration that happens when the form of sugar molecules breaks to release energy. Glucose is the most common form of sugar, from which the term glycolysis originates. The metabolic pathway helps in breaking and converting one molecule of glucose- C6H12O6 into two molecules of pyruvate – CH3COCOO + H+. The total amount of energy, released in the glycolysis process is used to produce energy molecules called ATP (Adenosine triphosphate) along with reduced NADH (nicotinamide adenine dinucleotide).

Meiosis involves two sequential cycles of nuclear and cell division, but only a single cycle of DNA replication. Meiosis is divided into meiosis I and meiosis II.

  • Meiosis I begins after the S phase, and meiosis II follows meiosis I.
  • Pairing of homologous chromosomes happens during meiosis which results in recombination of genes.
  • Four haploid daughter cells are formed at the end of meiosis.
<th scope="col">Meiosis I</th> <th scope="col">Meiosis II</th>
Prophase I Prophase II
Metaphase I Metaphase II
Anaphase I Anaphase II
Telophase I Telophase II

The chemiosmotic hypothesis suggests that the action of ATP synthase is coupled with that of a proton gradient. It is the action of a proton gradient that causes a proton motive force that allows ATP synthase to phosphorylate ADP and inorganic phosphate to ATP.

Transpiration pull or the suction force is the force which aids in drawing the water upward from roots to leaves. In leaves, some amount of water is used for photosynthesis and excess water is released into atmosphere through openings called as stomata.

Middle lamella is the outermost layer of cell wall shared by adjacent plant cells that glues them together. It is composed of polysaccharides called pectins.
The middle lamella is cementing layer between the cells. It is made up of Ca and Mg pectates. The basic chemical unit of pectin is galacturonic acid, which has the capability of salt formation with calcium and magnesium (an acid-base reaction).

Lysosomes can be termed as waste disposal system of the cell. For almost all type of organic materials they contain digestive enzymes.  For example, when cell gets damaged, lysosome may burst and the enzymes digest their own cell. Therefore lysosomes are known as the Suicidal bags of a cell or we can say that they posses different kind of hydrolases on release of these enzymes that cause death of cell.

Priya # 7 years ago

Lysosome itself burst to destroy an unwanted (damaged or teared) cell. So it is called as suicidal bag.

Dark reaction is also called carbon-fixing reaction. It is a light-independent process in which sugar molecules are formed from the carbon dioxide and water molecules. This reaction occurs in the stroma of the chloroplast where they utilize the products of the light reaction. Plants capture the carbon dioxide from the atmosphere through stomata and proceed to the Calvin cycle. In the Calvin cycle, the ATP and NADPH formed during light reaction drives the reaction and convert 6 molecules of carbon dioxide into one sugar molecule i.e. glucose.

Required in large quantities.

Play a pivotal role in disease prevention.

Play a pivotal role in providing energy.

Deficiency of micronutrients can cause Anaemia, Scurvy, Goitre, etc.

Deficiency of macronutrients can cause protein-energy malnutrition, Kwashiorkor, marasmus, etc.

Excessive intake of Vitamins harms the liver, mild nerve damage, etc.

Excessive intake of macronutrients results in cardiovascular disease, obesity, diabetes, etc.

Antioxidants, Minerals, and Vitamins are examples of macronutrients.

Proteins, fiber, carbohydrates, and fats are examples of micronutrients.

Micronutrients are mainly obtained from vegetables, fruits, cashews, eggs, all dairy products, etc.

Macronutrients are mainly obtained from legumes, beans, pulses, soy, tofu, cereals, potatoes, fish as nuts, oilseeds, milk, cheese, etc.

Their concentration is less than 1mg/gm.

Their concentration is equal to 1 mg or 1000 microgram.

Are found in a minute quantity in plants products.

Are found abundantly in all plants products.

They are trace elements.

They are major elements.

All micronutrients are minerals.

Includes both minerals and non-minerals.
