----------------------------------------------------------------------------------------------------------------------------------

Experiments as follows:

Experiment 1: Determination of the density of solid (denser than water) by using a spring balance and a measuring cylinder.

AimTo determine the density of a solid (denser than water) by using a spring balance and a measuring cylinder.

Apparatus RequiredA metallic object (any shape), iron stand, a spring balance, a measuring cylinder

TheoryMass per unit volume of a substance is called the density of a given substance.Let M be the mass of a given substance/object and V be its volume. Its density ρ is given byρ = MV=Mass of Object / Volume of ObjectIts S.I. unit is kg m-3.Let the weight of object measured by the spring balance in air = W g-wt.Initial volume of water in measuring cylinder = V1 mL.Final volume of water in measuring cylinder when object is fully immersed in water = V2 mL.Volume of object = Volume of displaced water = (V2 – V1) mLTherefore, density of object (ρ) = W (V2−V1) g cm-3

Procedure

1. Hang the spring balance vertically with the help of iron stand as shown in Fig. 2.2.

2. Find its least count by using the given formula:Least Count = Range of given spring balance Total number of divisions

3. Check the zero error (if any) and record it with proper sign.This is the reading of spring balance when no weight is suspended from its lower hook.

Measurement of weight of a given metallic object:

4. Hang the metallic object with the lower hook of the spring balance as shown in Fig. 2.3.

5. Take the reading of spring balance when the metallic object becomes static.

6. Obtain the true weight of the given metallic object by subtracting the zero error (if any) from the observe weight.

7. Repeat the experiment thrice and find its mean weight.Measurement of the volume of a given metallic object:

8. Pour some water into the measuring cylinder and record the initial level of water (lower position of meniscus) as shown in Fig. 2.4. Let the initial volume be V1 (mL).

9. Remove the metallic object from the spring balance and tie it by a thin strong thread and immerse it fully in the water in measuring cylinder.

10. Note down the new position of meniscus V2 (mL) in the measuring cylinder as shown in Fig. 2.5. The level of water rises up because the immersed object displaces water from its initial level.

11. Obtain the volume of the immersed metallic object by subtracting the two position of meniscus (water level) i.e. V2 – V1

12. Repeat the experiment thrice and find its mean volume.

ObservationsLeast count of spring balance: ………… g wt.Zero error of the spring balance: …………. g wt.Least count of measuring cylinder: ……….mLTable: Measurement of weight of a given metallic object.

ResultThe density of the given solid (heavier than water) = ……… kg m-3.

Precautions

1. Spring balance should be sensitive, stable and error free.

2. The horizontal pointer should move freely along the scale of spring balance.

3. Spring balance must be suspended vertically from fixed support of iron stand.

4. Reading should be taken only when oscillation of hanging object dies completely.

5. Eye should be kept in line (exactly horizontal) while taking the reading of spring balance as well as measuring cylinder as shown in figs. 2.6 and 2.7.

6. Solid object should be dried completely before measuring mass in air and when allowed to immersed in water.

7. While measuring the volume of object, the object should not touch sides and bottom of a measuring cylinder.

(b) packages materials coming from the endoplasmic reticulum

(c) a membrane made up of proteins and lipids

(d) is site for many biochemical reactions necessary to sustain life.

(e) is a fluid contained inside the nucleus

2. In the diagram given below, name the parts labelled as A,B, C,D,E,F, G, H, I & J and complete the table listing the differences between the plant cell and animal cell

PLANT CELL

ANIMAL CELL

1

Cell wall is present

2

Vacuoles are small in size

3

Plastids/chloroplasts are present

3. Name the two organelles in a plant cell that contain their own genetic material and ribosomes

4. Complete the following table by writing the name of the cell part or organelle in the right hand column that matches the structure/function in the left hand column. A cell part may be used more than once.

Structure/Function

Cell Part

1

Stores material within the cell

2

Helps in the digestion and removes wastes and digests dead and damaged cells. Therefore, it is also called as the “suicidal bags”.

3

Membrane-bound, sac-like organelles, present within the cytoplasm of the eukaryotic cells mainly involved in secretion and intracellular transport.

4

The sites of protein synthesis

5

Jelly-like substance in the cell

6

Organelle that manages or controls all the cell functions in a eukaryotic cell

7

Firm, protective structure that gives the cell its shape in plants, fungi, most bacteria and made up of cellulose

8

Contains chlorophyll, a green pigment that traps energy from sunlight and gives plants their green color

9

Digests excess or worn-out cell parts, food particles and invading viruses or bacteri

10

Produces a usable form of energy for the cell

11

Packages proteins for transport out of the cell

12

Produces lipids

13

Collection of DNA in the nucleus of eukaryotic cells in the form of a network

14

Provides shape, protects the inner organelle of the cell and acts as a selectively permeable membrane.

5. Differentiate between rough and smooth endoplasmic reticulum. How is endoplasmic reticulum important for membrane biogenesis

6. Given below is the diagram of a prokaryotic cell. Observe it and fill in the blanks given below:

Difference between eukaryotic cell and prokaryotic cell
