Magnifying glass. Models of the specimens as available in the museum. Dissecting kits. Singled celled unicellular organisms consist of a single cell i that can carry out all the life processes in naturej Materials: microscope slide, cover slip, permanent slide of plasmodium parasite, pond water.

Procedure: using a dropper, take a drop water from the pond water provided and. Cover with Cover slip and observe under the microscope. Look out for unicellular animals like amoeba, paramecium etc and unicellular plants like Chlamydomonas, chlorella, spirogyra etc. View the permanent slide of plasmodium parasite under the microscope. Make large labeled diagram of your observation. Questions: 1. Mention the habitat of each single celled organism you have drawn. Mention at least two unicellular plants and animals.

Aim: To examine single celled organisms of uncertain taxonomic position e. Euglena, Ch. Theory: Euglena is a single cell organism with uncertain taxonomic position. It shows a mixture of plant and animal features which makes it to be included in both zoological and botanical classification. Observe the feature and draw a large labeled diagram of'the organism. State the function of three 3 features you have labeled. Mention three 3 plant Chlamydomonas. Name the organ of locomotion for the animals.

Aim: To describe experimentally the effects of hypertonic, hypotonic and isotonic solution on the cell plasma. The cytoplasm shrinks and plasmalemma gets detached from the cell wall.

A cell placed in a less concentrated solution absorbs water and becomes turgid. Materials: Distilled water, Nacl solution pond water containing spirogyra cells, microscope slide, and microscope.

Procedure: From the Nacl provided, prepare molar solutions in the following concentrations; 0.

Once you have observed spirogyra cell add each of the molar solutions one at a time on the five 5 slides respectively. Leave for a few minutes and examine under the microscope.

Note which of the concentrations is hypertonic, hypotonic and isotonic to the spirogyra cells. Make diagrams of the cell from each of the five 5 concentrations you observed under the microscope. Copy and complete the table below Nacl concentrations 1 0.

Which of the concentration of Nacl solution is hypertonic, isotonic and hypotonic to the cell plasma? Aim: To observe and identify the various stages of mitotic cell division from projected permanent slide.. Material: Slide projector and permanent slides of different stages of Mitotic cell division. Theory: Mitosis is a cell division following the duplication of the Chromosomes. Each daughter cell produced has exactly the same number of chromosomes as in the parents' cell.

Mitosis produces two diploid cells. It occurs in the somatic cells, during growth, development and in asexual reproduction. Procedure: Carefully observe each of the projected slides and identify and draw each stage of the cell division observed. Define cell division , i 2. What type of cell division have you observed?

Where does this type of cell division occur specifically in plants and animals? State two significances of this type of cell division. Aim: To observe and identify the various stages of meiotic cell division from projected slides. Materials: Slide projector and permanent slides of various stages of meiotic cell division Procedure: Observe carefully each of the projected slides and identify each of the stages of the cell division observed and draw a well labeled diagram of each stage.

Define meiosis. Mention the specific places in both plant and animals where this type of cell division occurs. Aim: To extract, separate and identify photosynthetic pigments by adsorption chromatography using a column of icing sugar.

STB 121 PRAT - Unesco

Materials For chromatography: Petroleum ether, glass ,column, rubber cork, small bore rubber tubing, adjustable clip, glass rod, glass wool, icing sugar, teat pipette, beaker and stand, filter paper. Plants synthesize their own food by a process known ias photosynthesis. Some plants part contains a'green pi jment called chlorophyll in chloroplast cells which assist in absorbing light energy for photosynthetic process.

Note: The water bath should be heated and the busen flame extinguished before the petroleum ether is evaporated because it is highly flammable. Procedure for the chromatography of the extract. Note: Do not allow the column to run dry.

Always keep some petroleum ether above the column. Define photosynthesis.

List the conditions necessary for photosynthesis to take place. Mention the types of chlorophyll pigments present in plants and state the functions of each type. Apparatus for extraction of the pigments.

Application of the sample to the paper. Make a large well labeled diagram of the chromatography showing the positions of the separated pigments on the paper. Determine the RF value using the equations. Then identify the separate compounds.

Aim: To demonstrate the separation of the photosynthetic pigments by thin layer chromatography. Apparatus: Grease free microscope slide Cellulose MN powder or silica gel Distilled water Petroleum ether Acetone 2 beakers Foil Petri-dishes or watch glass Extract of photosynthetic pigments Fine capillary pipette. Compare the speed of separation and sensitivity with that of ascending technique of paper chromatography.

List the advantages of thin layer chromatography over the rest other forms of paper chromatography. Differentiate between thin layer chromatography and paper chromatography 4. Aim: To demonstrate that carbon dioxide is produce by green plants during respiration.

Theory: All living things plants and animals take part in gasous exchange, in which gases are exchanges between the living organisms and its environment. This referred to as external respiration.

In the cell of living organisms, complex food substances are as well broken down to simper substances with release of energy.Roots grow towards gravity and are said to be positively geotropic. By passive transport, an exchange of ions takes place between the external solution soil colloids readily yield ions on electrolysis and the cell.

Theory: Phototropism is the response of plant parts to the stimulus of light. Thus by calculating the transpiring surface area of the leaf and measuring the amount of water taken up by the shoot, the rate of transpiration per unit area of a leaf surface can possibly be calculated. Continue to collect samples of each group in 1. The lower the atmospheric pressure the greater is the rate of evaporation.

List other forms of response in plants apart from tropism and explain two.
