BIO Lab Practical Review

Front

Water always flows from a ________ to a ________ solution.

Back

Hypotonic/Hypertonic

Front

Label F represents which of the following?

Back

Coarse Adjustment

Front

Why was toluidine blue placed on the onion root tip?

Back

To make the chromosomes visible and easy to view with a microscope

Front

Label B represents which of the following?

Back

Objective Lens

Front

Label B represents which of the following?

Back

Coccus

Front

Define Isotonic solution.

Back

A solution with the same solute concentration as another solution, resulting in no net movement of water.

Front

What is the function of the Coarse Adjustment knob on a microscope?

Back

To quickly bring the specimen into focus by moving the stage up or down.

Front

What is the role of the Objective Lens in microscopy?

Back

To magnify the specimen being observed.

Front

What is the significance of using toluidine blue in microscopy?

Back

It stains the chromosomes, making them visible under a microscope.

Front

Differentiate between Hypertonic and Hypotonic solutions.

Back

Hypertonic solutions have a higher solute concentration than the cell, causing water to flow out; Hypotonic solutions have a lower solute concentration, causing water to flow in.
