Viruses are classified into which one of the three Domains?

Archaea

Bacteria

Eukarya

Viruses are not considered to be members of any of the domains.

Which statement is true of the comparison of diffusion and osmosis?

Diffusion involves liquids or gasses, where osmosis only relates to gasses.

Diffusion must always be facilitated, it will not occur passively.

Osmosis relates to molecules that are too big to pass through the cell membrane by themselves.

Osmosis is a special type of diffusion that involves water movement across a membrane.

What is assumed to be the advantage of the long, folded inner membrane of the mitochondria? What do the folds of the inner membrane do to make the mitochondrion more efficient?

cool off the cell\'s interior

allow for a place to store the mitochondrial DNA

increased surface area for reactions

None of these are correct regarding the folded inner membrane of mitochondria.

Which structures within a cell are responsible for making the ATP molecules used for cellular energy?

rough ER

smooth ER

lysosomes

mitochondria

Given that a cell\'s structure reflects its function, what do you predict would be the function of an animal cell with a very large amount of Golgi apparatus inside of it?

movement within the animal using cilia and flagella

cell growth and division management

secretion of lipids for use in insulating tissue

storage of pigmentation molecules

The cellular cytoskeleton of eukaryotes contains which of these types of protein fibers?

microtubules

intermediate filaments

microfilaments (actin filaments)

All of these types of fibers are involved in the cytoskeleton.

How is an individual cell identified by the organism in which it lives (assuming we are talking about a multicellular organism)? How does a cell show itself as \"friendly\" to the immune system in humans, for example?

the size and particular shape of the cell determine it\'s identity

the types of phospholipids in the bilayer determines the cell\'s identity

carbohydrate and protein pieces in and on the cell membrane identify the cell

All of these are correct in determining the cell\'s identity.

What is the term for the model used by biologists to describe the various proteins, carbohydrates, and other molecules that make up the cell membrane, and their structure and function?

the gel electrophoresis model

the fluid mosaic model

the egg cell model

the triphosphate model

The Cell Theory of Schleiden and Schwann was very important in establishing that...

all living things are always composed of multiple cells, some of which are living and most of which are non-living.

cells are part of a continuous membrane system, and are not individual living entities.

all living things are composed of at least one living cell.

DNA is a double helix in shape and is directly related to heredity and genetic traits.

Ribosomes are not considered organelles in a living cell, but they are extremely important because they are the site of protein assembly. Ribosomes can be found attached to the rough ER, and also floating freely in the cytoplasm of the cell. But the ribosomes themselves are assembled in what organelle?

mitochondria

vesicles

Golgi apparatus

nucleolus

Why, from a functional or performance standpoint, are most individual cells very, very, small (whether prokaryotic or eukaryotic)?

They only start small, but then grow huge in size and volume during their lifecycle.

The surface area to volume ratio has to be high enough for diffusion and osmosis to be able to occur.

They have to stay small so that all of the organelles and structural components do not slosh around too much within the cytoplasm and/or the nucleus.

All of these answers are true of the size of individual cells.

Which of these organelles would typically be found in large numbers within the cells of the human liver?

rough ER

smooth ER

lysosomes

chloroplasts

Every living cell on the planet is enclosed by a ...

cell wall composed of mainly cellulose.

group of cilia or flagella that allow for cell movement.

lipid bilayer cell membrane.

rigid protein coat that protects the cell from physical damage.

Which of the following is not part of our definition of a \"functional unit of life\"? In other words, which of these is not required to define a cell as a living thing?

Performs metabolic activities (acquires and uses energy to live).

Contains a membrane-bound nucleus (which houses the genetic material).

Senses and responds to its environment (in a variety of ways).

Can reproduce itself (although it doesn\'t always have to do so).

Which one of these forms of microscopy is the most powerful (gives the highest resolution)?

phase-contrast light microscopy

transmission electron microscopy

fluorescent light microscopy

reverse binocular light microscopy

	Archaea
	Bacteria

Solution

Ans D

Viruses is a separate classification altogether , it cannot be placed into any of the mentioned domains.

Whittaker\'s classification did not include viruses into its five Kingdom classification.
