ong>Answer:Chloroplasts /ˈklɔːrəˌplæsts, -plɑːsts/[1][2] are organelles that conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight, converts it, and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water in plant and algal cells. They then use the ATP and NADPH to make organic molecules from carbon dioxide in a process known as the Calvin cycle. Chloroplasts CARRY out a number of other functions, including fatty acid synthesis, much amino acid synthesis, and the immune response in plants. The number of chloroplasts per cell varies from one, in unicellular algae, up to 100 in plants like Arabidopsis and wheat.

A chloroplast is a type of organelle known as a plastid, characterized by its two membranes and a high concentration of chlorophyll. Other plastid types, such as the leucoplast and the chromoplast, CONTAIN little chlorophyll and do not carry out photosynthesis.

Chloroplasts are highly dynamic—they circulate and are moved around within plant cells, and occasionally pinch in two to reproduce. Their behavior is strongly influenced by environmental factors like light color and intensity. Chloroplasts, like mitochondria, contain their own DNA, which is thought to be inherited from their ancestor—a photosynthetic cyanobacterium that was engulfed by an early eukaryotic cell.[3] Chloroplasts cannot be made by the plant cell and must be inherited by each daughter cell during cell division.

With one exception (the amoeboid Paulinella chromatophora), all chloroplasts can probably be traced back to a single endosymbiotic event, when a cyanobacterium was engulfed by the eukaryote. Despite this, chloroplasts can be found in an extremely wide set of organisms, some not even directly related to each other—a consequence of many secondary and even tertiary endosymbiotic events.

The word chloroplast is derived from the Greek words chloros (χλωρός), which means green, and plastes (πλάστης), which means "the one who FORMS".[4]

Explanation:

Hypotonic Solution

The power of an extracellular solution to allow water to move in or out of a CELL through osmosis is CALLED ‘tonicity’. A solution’s tonicity relates to its osmolarity. A look at the hypotonic solution will help understand this better.

MOREOVER, it is the aggregate concentration of every solute in the solution. A solution with lower osmolarity has limited solute particles per litre of solution.

Whereas, a solution with higher osmolarity has comparatively more solute particles per litre of solution.

Definition of Hypotonic Solution

A hypotonic solution means something that has a lower solute concentration in comparison to another solution. A solution is not hypotonic, isotonic or hypertonic if there is no solution for comparison.

It helps scientists to describe cells. Osmolarity which is the concentration of a liquid in a certain number of solutes per litre of different solutions can tell experts the way in which water gradient and solute gradients can form.

Types of Hypotonic Solution

Hypotonic Solution

If the extracellular fluid has a lower osmolarity than the fluid inside the cell, it’s said to be hypotonic—hypo means less than—to the cell, and the net flow of water will be into the cell.

Hypertonic Solution

In the case of a reversal, the extracellular fluid with higher osmolarity than the cell’s cytoplasm will be hypertonic.

‘Hyper’ means greater than. Moreover, to the cell, and water will move out of the cell with lower concentration to higher concentration.

Isotonic Solution

In the case of an isotonic solution, the extracellular liquid has a similar osmolarity to the cell. Moreover, there will be no net movement of water in or out from the cell. ‘Iso’ means same or similar.

Examples of Hypotonic Solutions

Animal Cells

Firstly, animal cells do not contain a cell wall. Moreover, animals depend on their skin to separate the outer environment from their internal organs.

Hence, the fluid in their body’s cavity is regulated by a series of proteins and membranes. The liquid remains isotonic or slightly hypotonic in comparison to the cells of the animal.

Moreover, it keeps them plump and healthy without damaging them.

Plants and Fungi

Large plants and fungi monitors and controls the surrounding around their cells. Moreover, it helps to ensure that the environment is always a hypotonic solution in comparison to the cells.

It creates cells which are turgid. The turgid cell pushes out their cell walls or membranes. It further pushes against each other creating a strong and tight structure.

The organisms keep on cycling solutes which keeps the water in the contents of the cell. If anyone ever over-fertilize their GARDEN, they KNOW that it is not good for the plant.

Malnutrition among under-five children is an important concern for the health authorities in India. The aim of the present review was to assess the burden of under-nutrition and over-nutrition, its determinants and strategies required to tackle malnutrition among under-five children in India. Recent data were collected from Google search, Medline, and others. The information retrieved was reviewed and analyzed for DISCREPANCIES. Existing evidence shows that the prevalence of under-nutrition among under-five children was high and varied widely (under-weight: 39-75%, stunting: 15.4-74%, WASTING: 10.6-42.3%) depending on the assessment methodology adopted. Studies on assessment of over-nutrition status among under-five children were limited. Distribution of VARIOUS types of risk factors and its influence on nutrition status of children in a given set up should be analyzed for planning the CONTROL measures. Strengthening public health interventions for mild malnutrition cases and vulnerable groups, effective implementation and evaluation of the strategies at regional level, research on overweight, obesity and its etiological factors and steps for improving socioeconomic development are the prerequisites for tackling malnutrition among under-five children in India

BIOLOGY

ANSWER

The primary sex organ, the testis in males produce gametes i.e. sperms. Mature sperm cell consists of a head, a neck, a middle piece and a tail. A plasma membrane envelops the WHOLE body of sperm. The sperm head contains a very little cytoplasm, an ELONGATED haploid nucleus, the ANTERIOR portion of which is covered by a cap-like STRUCTURE, acrosome. The short neck contains two distinct granules- the proximal and distal centrioles. The proximal centriole plays a crucial role during the first cleavage of the FERTILIZED ovum. The distal centriole gives rise to the axial filament of the long tail of the sperm. The middle piece of mammalian sperm cell possesses numerous mitochondria. These mitochondria are 25 to 30 in number which are spirally arranged. They produce energy for the movement of the sperm cell.

Thus, mitochondria, nucleus, and centriole are present in the sperm and E.R. is absent in the human sperm.

During oxygenic photosynthesis, light energy transfers electrons from WATER (H2O) to CARBON dioxide (CO2), to produce CARBOHYDRATES. In this transfer, the CO2 is “reduced,” or receives electrons, and the water becomes “oxidized,” or loses electrons. Ultimately, oxygen is produced along with carbohydrates.

To prepare a temporary mount of leaf peel to show its stomata. For this you need leaf of a plant, forceps, watch glass, slide, coverslip, brush, needles, safranin, glycerin, and MICROSCOPE.

Procedure:

i. Peel off the leaf from it’s under surface and put the peel in a watch glass containing water.

ii. Add a few drops of saffron stain into the watch glass to stain the peel.

iii. Take out the stained peel on the cleaned slide.

iv. Remove the excess stain from the slide.

v. Put a drop of glycerin on the slide over the peeled cover it gently with coverslip without air bubbles.

vi. Observe the slide under the microscope.

Observations:

i. The epidermis is SEEN in the mount. It appears as a single layer of CELLS without intracellular spaces.

ii. Minute pores (OPENINGS) are seen embedded in between epidermal cells.

Stomata are minute apertures (openings) present on the surface of the leaf. Stomata are generally more on the lower epidermis. Each stoma is SURROUNDED by two bean-shaped cells called guard cells. The inner wall facing pore is thicker than the outer wall. The turgidity of guard cells controls the opening and closing of stomata. Stomata help in exchange of gases and water vapours between the atmosphere-land leaf
