Question

• Collect water from a lake or pond that appears dark green and
contains filamentous structures.
Put one or two filaments on a slide.
Put a drop of glycerine on these filaments and cover it with a coverslip.
Observe the slide under a microscope.
Can you identify different tissues in the Spirogyra filaments?​

Answer 1

Answer:

We see that amoeba divides with different planes in a separate slide

Explanation: Amoeba is the simplest unicellular organism. It does not have any shape, complex structure or organs .

Answer 2

Answer:

Yes, many kinds of tissues that can be seen under a microscope make up spirogyra filaments. Spirogyra is a multicellular, filamentous, green alga in which there is no tissue differentiation and cells are identical.

Explanation:

• Green multicellular algae that are long, thin, and typically unbranched makeup filaments. Spirogyra filaments have elongated, cylindrical cells with a thick covering of chloroplasts and a central vacuole surrounded by cytoplasm.

• Spirogyra filaments include a variety of tissues that can be seen under a microscope, including:

• The epidermis, which is made up of the filament's outermost layer of cells, shields and supports the deeper tissues.

• The cortex, a layer of cells underneath the epidermis, is in charge of synthesizing and storing food for the organism.

• The nucleus, chloroplasts, and other organelles are located in the central cylinder, which is the layer of cells closest to the filament's outer surface.

• By observing the Spirogyra filaments under a microscope, it is possible to see these different tissues and study their structure and function in more detail.
• The addition of glycerine helps to preserve the structure of the filaments and makes them easier to observe.
• Therefore, we can identify different tissues in the Spirogyra filaments.
