1. Lysosome is regarded as a body that is covered by membrane, a little smaller than
mitochondrion and functions as storage for several hydrolytic enzymes. The enzymes in
lysosome can digest substances that are engulfed by the cell and under certain conditions
can destroy the cell itself.
(a) Name ONE type of cell in the human body that contains many lysosomes. Explain
why the cell contains many lysosomes.
(b) State ONE different between the lysosome membrane and the mitochondrion
membrane.
(c) State ONE special feature of the lysosome membrane.
(d) Explain how lysosome acts to release its enzymes in the cell.

- The endoplasmic reticulum (ER) and Golgi apparatus are two organelles that are not physically joined, yet materials can still be exchanged between them. How can materials, such as proteins, move between the ER and Golgi when these organelles are not touching each other?

- -Mature parent cell Budding- cell 1 μη Test II. Examine the micrograph of the yeast cells. The scale bar under the photo is labeled 1 um. The scale bar works in the same way as a scale on a map, where, for example, 1 inch equals 1 mile. In this case the bar represents one thousandth of a millimeter. Using the scale bar as a basic unit, determine the diameter of the mature parent cell and the new cell. Start by measuring the scale bar and the diameter of each cell. The units you use are irrelevant, but working in millimeters is convenient. Divide each diameter by the length of the scale bar and then multiply by the scale bar's length value to give you the diameter in micrometers.arrow_forwardWhich of the following is the most fundamental feature that enables the cell to function as a distinct entity, separate from its environment?
