    Antacid is a substance that neutralizes the acidity in the stomach because it contains bases. We take antacid such as milk of magnesia, which contains magnesium hydroxide. These bases react with excess of acids released in stomach and neutralize their effects, thus giving us relief.

    Plants need nitrogen to grow, while most of the plants get there dose of nitrogen from the soil nitrates, the carnivorous plants lack the supply as they live in bogs. 

    Thus in order to get the adequate amount of nitrogen which is essential for their growth carnivorous plants feed on insects.

    The cell membrane is also known as the plasma membrane. It is the outermost covering of animal cells. It is a semi-permeable membrane composed of lipids and proteins. The main functions of the cell membrane include:

    1. Protecting the integrity of the interior cell.

    2. Providing support and maintaining the shape of the cell.

    3. Helps in regulating cell growth through the balance of endocytosis and exocytosis.

    4. The cell membrane also plays an important role in cell signalling and communication.

    5. It acts as a selectively permeable membrane by allowing the entry of only selected substances into the cell.

    Humus (or humous) is the organic matter in the soil. It is made of dead parts of plants and animals. Humus takes in water and has plenty of nutrients. Nitrogen is the most important. Plants put roots into the soil to get the water and nutrients. Humus is good for plants because it is like a sponge. The dark color of humus (usually black or dark brown) helps to warm up cold soils in the spring.

    .. ... 6 years, 3 months ago

    Humus is the dark organic matter that forms in soil when dead plant and animal matter decays. Humus has many nutrients that improve the health of soil, nitrogen being the most important. The ratio of carbon to nitrogen (C:N) of humus is 10:1

    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. -------------------------------------------------------------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.

    Yogita Ingle 6 years, 3 months ago

    Plants, especially the green ones prepare their own food by a process called photosynthesis. They are therefore known as autotrophs and primary producers in the food web. All green plants comprise a specialized structure known as chloroplast, and the green pigments called chlorophyll within the cell and are responsible for the synthesis of food.

    Various methods of asexual reproduction are:

    i. Binary Fission - Fission in which the parent cell divides to form two similar daughter cells. Example - Amoeba.

    ii. Multiple Fission - Fission in which the parent cell divides to produce more than two daughter cells. Example - Plasmodium.

    iii. Budding - The reproductive method in which an organism produces an outgrowth on its body surface, which then matures and develops into a new individual. Example - Hydra.

    iv. Spore Formation - Spore formation is an asexual mode of reproduction found in certain multicellular organisms like <i>Rhizopus.</i> The thick walled spores have the capacity to develop into new individuals under suitable conditions.

    The female silk moth lays hundreds of eggs on the mulberry leaves. The larvae that hatch out of the eggs are called silk worms or caterpillars. The caterpillars feed on mulberry leaves vigorously. When the silkworms are ready to enter the next stage of its development called pupa it stops feeding and its salivary glands secretes a fibre around the pupa to hold itself. The fibre is made up of protein called fibroin which hardens on exposure to air. Then it swings its head from side to side in the form of figure of eight forming a cover around pupa. This covering is known as cocoon. The further development of the pupa into moth continues inside the cocoon. The most common silk moth is the mulberry silk moth.
