7 Fun Experiments to Try at the Chemistry Lab

7 Fun Experiments to Try at the Chemistry Lab

Most people are fairly divided on science: either you love it, or you hate it. If you belong to the latter camp, it is probably because science classes may seem too technical and boring. However, that is a great misperception. If you know what to do, scientific experiments can be fun—even magical! With the right scientific equipment and know-how, you can take up a number of interesting projects. In the chemistry lab, you can make gooey slime, invisible ink, and glittering crystals! Here are 7 simple and fun experiments to try out at the chemistry lab! 1. Layered Drink You must have seen beautiful drinks with distinctly separate layers and colors. Gravity-defying and magical as these drinks may look, they are actually based on simple scientific manipulation. This type of drink is based on the principles of density: the denser a liquid, the more it will sink. Effectively, you can layer one type of drink on another. All you need is: two-four...

Angiosperm

Angiosperm

Hi viewers Today we are going to discuss about the The Angiosperms. Angiosperms are eukaryotic flower producing fruit producing plants. They may be May be herb, shrub and tree or may be annual, biennial and perennial type PROPERTIES ANGIOSPERM They are eukaryotic in nature They are autotropic Roots,stem and leaf are distinct Xylem and phloem are present Seeds are covered with fruits Fertilisation takes place after few days of pollination Leaves are of various types Flowers are of various types Mango,Coconut, etc. 1.   State five distinctive features of angiospermic plants. (3) Ans. i) Presence of flowers. ii) Formation of fruit. iii) Pollen grains are borne in anther. iv) Existence of double fertilization. v) Formation of triploid endosperm after fertilization. 2.  What are angiosperm and phanerogam? (1+1) Ans. a) The angiosperms are the highest evolved vascular plant producing flowers and fruits. b) All flowering plants are called phanerogams. 3.   Name three structures absent in dicot seed. (1) Ans. Coleoptile, coleorhiza and scutellum 4.  Name a nonendospermic monocot plant. (2) Ans. Arum 5. Name the fruit where fruit coat and seed coat...

The Gymnosperm

The Gymnosperm

Hi viewers Today we will discuss about the Gymnosperm. Basically, Gymnosperms are eukaryotic plants, which have naked seed and fertilization takes place after one year of fertilization. PROPERTIES GYMNOSPERM They are eukaryotic in nature They are autotrophic Roots,stem and leaf are distinct Woody stem and xylem are present Naked seeds are present Spiny leaves are present Fertilisation takes place after one year of pollination Male cone and female cone are present They are evergreen and perennial Eg. Pinus and Cycas, etc. 1.  Name one gymnosperm where xylem vessels and companion cells are present. (1) Ans. Gnetum 2.  Differentiate between bract scale and ovuliferous scale. (2) Bract scale Ovuliferous scale 1. They are located at the base of the microsporophyll. 2. They have a membranous structure. 3. They protect the base of the megasporophyll and provide their attachment with the axis. 1. They are the upper lateral projections of the megasporophyll. 2. They have a more woody structure. 3. They provide support and protection to the ovules. Differentiate between endosperm of gymnosperm and endosperm of...

The Pterydophyta

The Pterydophyta

Hi viewers Today we will discuss about the world of Pterydophyta Definition of Pterydophyta Pteridophytes are vascular plants that reproduce and disperse via spores, these plants produce neither flowers nor seeds and it also show alternation of generation. PROPERTIES PTERYDOPHYTA Autophytic nutrition. Terrestrial Body is divisible into root, stem and leaf They are nonflowering plants Reserve food material is starch Cell wall- cellulose Sporophytes and Gametophytes are separate plants Adult life starts with sprophyte Chemotropism- occurs by synthesis of malic acid Vascular tissue is present Eg. Any kind of fern 1.  What are the main characters of Pteridophytes? (3) Ans. The main characters of Pteridophytes are in the following: a) Pteridophytic plants are advanced than the bryophytes but less advanced than gymnosperms, and mostly they are terrestrial. b) They are non-flowering plants, and do not bear flowers, fruits and seeds. c) The leaves are generally of two types- small and scale like microphyllous and large megaphyllous. d) The plant body is the sporophyte, which is well developed, autotrophic and long lived....

The Bryophyta

The Bryophyta

Hi viewers Today we will discuss about the world of Bryophyta Definition of Bryophyta A division of nonflowering plants characterized by rhizoids rather than true roots and having little or no organized vascular tissue and showing alternation of generations between gamete-bearing forms and spore-bearing forms; comprises true mosses (Bryopsida) and liverworts (Hepaticopsida) and hornworts (Anthoceropsida) PROPERTIES BRYOPHYTA Autophytic nutrition. Terrestrial Aphibians among the Plant Kingdom because it needs water during the reproduction Thallus body Reserve food material is starch Cell wall- cellulose Sporophyte depends upon the gametophyte Adult life starts with gametophyte Chemotropism- occurs by synthesis of sucrose Vascular tissue is absent Eg. Any kind of moss Q and A on Bryophyta What are the main characters of Bryophyta? (3) Ans. The main characters of Bryophyta: a) Bryophyta is a kind of non-flowering, autophytic independent plant. b) The gametophytic plant body of the lower Bryophytes are not differentiated into root, stem and leaves, Eg.- Riccia. They are thallus like. c) Conducting tissue systems (xylem and phloem) are absent. It...

The Algae

The Algae

Hi viewers: Today we will discuss about the algae, which are Eukaryotic plants, my be microscopic single cellular or macroscopic multicellular.  These are grouped under plants kingdom PROPERTIES ALGAE  Autophytic nutrition. Exception- Cephaleuros (a parasitic algae) Fresh water or marine Thallus body Reserve food material is starch Cell wall- cellulose True parenchymatous cells are present Nonflowering Microscopic or macroscopic Reproduction- vegetative, asexual and sexual Eg. Spirogyra, Volvox, Chlamydomonas, Chara etc   a.  Chlamydomonas b.  Spirogyra c.  Volvox Q and A of Algae Distinguish between coenocyte and coenobium. (1) Coenocyte Coenobium 1. A mass of cytoplasm surrounding many nuclei and enclosed by a cell wall. It is found in certain algae and fungi. 1. A colony of Volvox is called coenobium. Mention few characteristics of (unicellular) Chlamydomonas. Ans. a. Chlamydomonas is a unicellular motile green alga possessing two flagella and usually a cup shaped chloroplast. b. Cell wall is thin and composed of cellulose. c. The basal granules situated at the base of the flagella are called blepharoplasts. d. At the base of each flagella lies one contractile vacuole,...
