Question 1

Peroxisomes are membrane-bound organelles.

Accepted Answer

Peroxisomes are organelles enclosed by a single membrane, making them membrane-bound organelles.

Question 2

The fluid contained in the nucleus is the _________.

Accepted Answer

nucleoplasm

Question 3

Some of the largest spherical cells in the human body (for example,oocytes)have a diameter of approximately

Accepted Answer

The options given include sizes ranging from nanometers to centimeters. The largest spherical cells in the human body are oocytes, which have a diameter of about 100 micrometers or 100,000 nanometers. Therefore, the best choice is option E, which is 100 micrometers in diameter.

Question 4

One example of a membrane-bound organelle is a ribosome.

Accepted Answer

Ribosomes are not considered membrane-bound organelles because they do not have a membrane surrounding them. They are composed of RNA and proteins and are found either floating freely in the cytoplasm or attached to the endoplasmic reticulum, but they are not surrounded by a membrane. Examples of membrane-bound organelles include the nucleus, mitochondria, lysosomes, and endoplasmic reticulum.

Question 5

Another name for the intracellular fluid is

Accepted Answer

The intracellular fluid is the fluid inside the cell, and it consists of the cytosol, which is the liquid component of the cytoplasm. Therefore, choice A) is the correct answer. Choice B) (interstitial fluid) refers to the fluid in the spaces between cells, choice C) (intercellular matrix) refers to the material between cells (such as the extracellular matrix), choice D) (cytoplasm) refers to the entire contents within the cell membrane (not just the fluid), and choice E) (cisternae) refers to flattened membrane-bound sacs within the cell that are involved in processes such as protein and lipid synthesis.

Question 6

Which is a non-membrane-bound organelle

Accepted Answer

Microtubules are a part of the cytoskeleton, but they are not membrane-bound organelles. The other options (Lysosome, Golgi apparatus, Rough endoplasmic reticulum, and Mitochondrion) are membrane-bound organelles.

Question 7

The shape of skeletal muscle cells is described as

Accepted Answer

Skeletal muscle cells have a cylindrical shape.

Question 8

The microscope of choice for a detailed three-dimensional study of the surface of a specimen is the

Accepted Answer

The scanning electron microscope is able to produce high-resolution, 3D images of a sample's surface by scanning it with a beam of electrons. This is not possible with a light microscope, which only produces 2D images, or a transmission electron microscope, which is better suited for studying the internal structure of a sample. A telescope is not a microscope and is not capable of studying the surface structure of specimens.

Question 9

What unit of measurement is often used to measure cell size

Accepted Answer

Micrometers (also known as microns) are the most commonly used unit of measurement for cell size as they are smaller than millimeters and larger than nanometers, making them ideal for measuring the size of individual cells. Hectometers and centimeters are too large to accurately measure cell size, while nanometers are too small.

Question 10

Cartilage cells and intestinal lining cells are described as being cube-shaped.

Accepted Answer

The answer of Cartilage cells and intestinal lining cells are...

Question 11

The centrosome is considered to be an inclusion.

Question 12

The _______ is responsible for forming the outer,limiting barrier of a cell.

Accepted Answer

The plasma membrane is a selectively permeable phospholipid bilayer that forms the outer boundary of a cell, separating its internal environment from the external environment. It is responsible for regulating the movement of molecules in and out of the cell.

Question 13

The largest internal cellular structure is known as the ______ and is the cell's control center.

Accepted Answer

The largest internal cellular structure is the nucleus, which is considered the control center of the cell as it contains genetic information in the form of DNA that controls the cell's activities. The Golgi apparatus is responsible for packaging and modifying proteins, lysosomes are responsible for breaking down waste materials, and the smooth ER is involved in lipid synthesis and detoxification. The cytosol is the fluid portion of the cytoplasm.

Question 14

An image produced by passing visible light through a specimen is obtained using the

Accepted Answer

The passage indicates that the image is produced by passing visible light through a specimen. The only microscope listed that uses visible light is the light microscope, so the answer is B. The transmission electron microscope and scanning electron microscope both use electron beams, the dissecting scope is used for studying larger organisms or specimens, and the "ocular examination method" is not a commonly used term in microscopy.

Question 15

Most cells in the human body are between 1 $\mu$m and 100 $\mu$m in diameter.

Accepted Answer

This is true, as most cells in the human body fall within this size range. However, there are exceptions such as gametes (sperm and egg cells) which are smaller, and certain nerve cells which can be very long (up to a meter or more) but still have a small diameter.

Question 16

If the nutrient glycogen is found stored inside a cell,it is considered a(n)

Accepted Answer

Glycogen is a carbohydrate polymer and is stored as an inclusion inside cells, rather than being a membrane-bound or non-membrane-bound organelle or a pigment.

Question 17

Which is not considered part of the cytoplasm

Accepted Answer

The nucleus is a membrane-bound organelle that is not considered part of the cytoplasm. The cytoplasm is composed of the cytosol, organelles, and inclusions.

Question 18

One of the general functions that all cells must maintain throughout their life is the ability to divide and give rise to new cells.

Accepted Answer

The answer of One of the general functions that all...

Question 19

The diameter of a red blood cell is a little less than 1 $\mu$m.
