Which type of cell? (It has a nucleus, membrane-bound organelles). Check all that apply.

Are eukaryotes multicellular or unicellular?

Two students are reading an article about the evidence of the endosymbiotic theory. As they are reading, they have drawn images of what they believe to be occurring on index cards. The two students are engaging in a discussion on how the index cards should be ordered to accurately show the evolution of eukaryotic cells.

Student A claims the order should be B, E, D, A, C. Their reasoning is that since the small circles without lines in the index cards represent chloroplasts, photosynthesizing organisms evolved before aerobic organisms.

Student B claims the order should be B, A, C, E, D. Their reasoning is that since the small ovals with lines in the index cards represent mitochondria, respiratory organisms evolved before photosynthesizing organisms

Use the diagram to answer the question. Which statement below is accurate about the discussion above?

____________ & _________________ are organelles that definitely arose from endosymbiosis.

"Endosymbiosis" means

Both eukaryotic and prokaryotic cells have:

ribosomes

cell membranes

Mitochondria and chloroplasts have their own DNA.

Mitochondria , chloroplast , and bacteria are similar in size.

Mitochondria and chloroplast do not divide on their own.

Eukaryotes are thought to have evolved by a prokaryote engulfing one heterotrophic bacteria and one photosynthetic bacteria.

Which statement below correctly explains and gives the importance of the endosymbiotic theory?

The shape of this bacterial cell is:

The shape of this bacterial cell is:

A prokaryotic cell has a cell membrane.

Bacterial cells can have one of three shapes. Which of the following is not a common shape of bacterial cell?

Which of the following is the largest organism type?

Bacteria are treated with:

The organelle described as a long, thin-like projection that helps with movement.

Organelle that creates proteins in bacteria.

Where is the DNA located in prokaryotic cells?

In the bacterial cell, the chromosome or DNA is located floating freely in the cytoplasm in a region called the:

Bacteria have small, circular chromosomes separate from the nucleoid that they can easily exchange with other bacteria called:

Bacteria that line up in chains have the prefix:

Bacteria that arrange in clusters have the prefix:

These bacteria are:

What would be the gram stain results of a bacteria with this cell wall? (Hint: look at the peptidoglycan layer in the cell wall.)

Select all that apply to this bacteria:

These bacteria have a thin peptidoglycan cell wall and therefore have an outer membrane (capsule) to help protect them.

Which part of a bacteria cell wall "holds" the Gram stains?

These bacteria are

This diagram shows a bacterium that will be _________________ when stained with the Gram staining method.

Select all that apply to the above bacterial species that were stained using the Gram Stain method. (There are three).

Select all that apply to the above bacterial species that were stained using the Gram Stain method. (There are three)

The term that describes bacteria being found virtually "everywhere"

this term indicates that the morphology of bacteria is rod shaped

this term indicates that the morphology of bacteria is spherical shaped

What bacterial arrangement is represented in this picture?

What bacterial morphology is present in the image?

True / False:

Gram negative bacteria has MORE layers of protection than Gram positive bacteria

Gram positive bacterial cell walls are so thick that when they are dyed, they are able to absorb more crystal violet and appear purple during Gram Stain.

Gram negative bacteria have an extra outer layer of ____________ which help give them more protection and antibiotic resistance.

This scientists finally disproved spontaneous generation once and for all.

Pasteur proved the spontaneous generation theory wrong and also demonstrated microorganisms are everywhere.
