Question 4

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

Accepted Answer

Human cells and plant cells have fundamental differences in structure and function, such as the presence of cell walls and chloroplasts in plant cells, which are not found in human cells.

Accepted Answer

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

Question 8

Membrane-enclosed structures in eukaryotic cells are called ________.

Accepted Answer

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

Question 9

Prokaryotic cells are generally larger than eukaryotic cells.

Accepted Answer

Eukaryotic cells are generally larger than prokaryotic cells. Prokaryotic cells are usually around 0.1-5.0 micrometers in size, while eukaryotic cells range from 10-100 micrometers. Some eukaryotic cells, such as ostrich egg cells, can even be seen with the naked eye.

Question 10

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 11

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 12

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 13

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 14

The ________ found in eukaryotic cells have cristae.

Accepted Answer

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

Question 15

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

The hydrophobic tails of phospholipids are nonpolar and thus repel water molecules. Therefore, they are oriented towards the center of the membrane, creating a hydrophobic environment. The hydrophilic heads of phospholipids, which are polar and interact with water, are oriented towards the aqueous environments both inside and outside the cell.

Question 16

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 17

A ribosome has internal cristae.

Accepted Answer

Ribosomes do not have internal cristae. Cristae are found in mitochondria, which are the powerhouses of the cell.

Question 18

The ________ endoplasmic reticulum is covered with ribosomes.

Accepted Answer

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

Question 19

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 only allows certain substances to pass through, while preventing others from entering or leaving the cell. This is important for maintaining homeostasis and protecting the cell from harmful substances. Allowing solutes to enter and leave indiscriminately would be harmful to the cell.

Question 20

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

Accepted Answer

This is true. A microscope is a device that uses lenses to magnify objects that are too small to be seen with the naked eye.
