Question 1

The ________ is the place where the majority of the genetic material in a eukaryotic cell is stored.

Accepted Answer

The answer of The ________ is the place where the...

Question 2

A ribosome has internal cristae.

Accepted Answer

Ribosomes do not contain internal cristae. They are composed of RNA and protein molecules and are responsible for protein synthesis. Cristae are folds in the mitochondrial inner membrane that increase its surface area for energy production.

Question 3

In the chloroplast,pancake-like,membrane-bound structures known as ________ are arranged into stacks.

Accepted Answer

The answer of In the chloroplast,pancake-like,membrane-bound structures known as ________...

Question 4

The ________ has a double membrane,DNA,and stacks of hollow membranous disks,but no cristae.

Accepted Answer

The answer of The ________ has a double membrane,DNA,and stacks...

Question 5

A microscope is used to obtain a magnified view of an object.

Accepted Answer

This is a true statement. A microscope uses lenses to magnify an object, allowing for closer inspection of its structure and details.

Question 6

Membrane-enclosed structures in eukaryotic cells are called ________.

Accepted Answer

The answer of Membrane-enclosed structures in eukaryotic cells are called...

Question 7

During the process of photosynthesis,________ is given off as a by-product.

Accepted Answer

The answer of During the process of photosynthesis,________ is given...

Question 8

The hydrophobic portions of a membrane's phospholipid bilayer are oriented toward the interior of the membrane and pointed away from aqueous environments.

Accepted Answer

This is because the hydrophobic portions of phospholipids are nonpolar and therefore repel water, while the hydrophilic portions are polar and interact with water. Thus, they arrange themselves such that the hydrophobic tails are shielded from the aqueous environment by the hydrophilic heads. This forms a stable barrier that enables the cell to maintain its internal environment while communicating with the external environment.

Question 9

The ________ endoplasmic reticulum is covered with ribosomes.

Accepted Answer

The answer of The ________ endoplasmic reticulum is covered with...

Question 10

A membrane that is selectively permeable causes damage to the cell by allowing solutes to enter and leave the cell indiscriminately.

Accepted Answer

A selectively permeable membrane allows only certain small molecules or ions to pass through, while blocking larger molecules and charged particles. This function is essential for maintaining the appropriate internal environment of the cell and preventing harmful substances from entering or important molecules from leaving.

Question 11

The components of the cytoskeleton that provide mechanical strength to cells and reinforce the membranes of organelles are called ________.

Accepted Answer

The answer of The components of the cytoskeleton that provide...

Question 12

The symptoms of ________ range from relatively mild muscle weakness to hearing and vision loss and severe muscle and nerve impairment.

Accepted Answer

The answer of The symptoms of ________ range from relatively...

Question 13

Certain cells found in humans are identical to certain cells found in plants.

Accepted Answer

Human and plant cells have distinct structures and functions, although they share some common organelles like mitochondria. However, plant cells have unique features such as chloroplasts and a cell wall that are not found in human cells.

Question 14

A cell structure that pinches off from a membrane,encloses material,and then fuses with another membrane to release its contents at its destination is called a(n)________.

Accepted Answer

The answer of A cell structure that pinches off from...

Question 15

In eukaryotic cells,most of the ATP used for cellular reactions is produced by the specialized,membrane-enclosed compartments known as ________.

Accepted Answer

The answer of In eukaryotic cells,most of the ATP used...

Question 16

The microfilaments that allow cells to move contain the protein ________.

Accepted Answer

The answer of The microfilaments that allow cells to move...

Question 17

In general,chemical reactions occur more efficiently and quickly in ________ because the reactants of different reactions are concentrated within compartments in the cell specialized to contain those reactions.

Accepted Answer

The answer of In general,chemical reactions occur more efficiently and...

Question 18

Prokaryotic cells are generally larger than eukaryotic cells.

Accepted Answer

Prokaryotic cells are generally much smaller than eukaryotic cells.

Question 19

All of the energy in the food we eat is produced when organelles in plants called ________ convert the energy in sunlight to chemical energy.

Accepted Answer

The answer of All of the energy in the food...

Question 20

The ________ found in eukaryotic cells have cristae.

Accepted Answer

The answer of The ________ found in eukaryotic cells have...
