Question

to show budding in hydra practical​

Answer 1

Explanation:

hope this helps you:

Aim: To study budding in hydra with the help of prepared slides

Theory:

1.    Reproduction: Plants and animals reproduces (i.e., create new individuals) either by asexual method or by sexual method.

2.    Asexual reproduction: When an organism reproduces by single organism, it is called asexual reproduction. The different ways of asexual reproduction are fission, budding and regeneration in animals.

Budding:  Type of asexual reproduction in which a small bud develops as an outgrowth due to repeated cell division at one specific site. These buds develop into tiny individuals and when fully mature detach from the parent body and become new independent individual.

For e.g., Hydra and Yeast reproduce through budding

Procedure:

1.    Place the permanent/prepared slides of hydra showing different stages of reproduction on the stage of microscope.

2.    Make the adjustments in mirror of the microscope for focussing maximum light on the slide.

3.    Adjust the eye-piece so that the slide is clearly seen. Draw diagrams of the stages of budding hydra cells.

Observations:

  1. Hydra is tubular, radially symmetric body in shape.

  2. It is a multicellular organism.

  3. In the second stage, hydra shows a small growth on it called ‘bud’.

  4. In the third stage, the hydra shows that in some situations many such chain of buds is seen on the parent cell. This process is called ‘budding’.

  5. On maturity the buds get separated from parent cell to form and grow’ as a new organism. This process is called budding.

Conclusion:

The given slides showed the small growth (bud) on hydra. These buds on maturity separates from parent cell and grow as a new organism, hence, hydra shows budding.

Precautions:

1. Use microscope very carefully. Do not disturb its adjustments.

2. The slides shown under the microscope should not be disturbed.

3. Set the mirror of the microscope for better focus of light on the slide.

4. The slide can be seen under low power or high power of the microscope. These adjustments should be done very carefully.
