Select ALL of the features that a plant cell has but an animal cell does not.

		nucleolus
		chloroplast
		vacuole
		Golgi apparatus
		centrioles
		cell wall

Select ALL of the features that eukaryotic cells have but prokaryotic cells do not.

		DNA
		ribosome
		endoplasmic reticulum
		mitochondrion
		nucleus

Select ALL of the functions of a cell wall of a plant.

		Cell walls provide the plant structural support allowing plants to grow upright.
		Cell walls help the cell maintain a specific shape.
		Cell walls help plant cell create turgor pressure.

The endoplasmic reticulum is continuous with the nuclear envelope.

True

False

Which of these organelles in a eukaryotic cell has DNA housed within them. Select ALL of the correct answers.

		nucleus
		Golgi Apparatus
		ribosomes
		mitochondrion
		endoplasmic reticulum

Place the following events in order.

  

Protein gets processed in the Golgi apparatus.

DNA synthesizes RNA via transcription.

Mature RNA leave the nucleus through the nuclear pore.

RNA is translated into a ribosome in the rough endoplasmic reticulum.

Protein leaves the rough endoplasmic reticulum in a transport vesicle.

Cellular respiration is more efficient at producing ATP than fermentation.

True

False

During the electron transport chain, energy from the molecules _____ is used to pump hydrogen ions into the _____.

		NADH and FADH2 ... mitochondrial matrix
		NADH and FADH2 ... intermembrane space
		NADH ... intermembrane space
		NADH ... mitochondrial matrix

In dephosphorylation, ATP is hydrolyzed into ADP and inorganic phosphate and _____.

		energy remains constant
		energy is released
		energy is required

Without this molecule, cellular respiration does not happen, because it is the final electron acceptor. What is it?

		O2
		water
		FADH2
		CO2

Yeasts are single-celled eukaryotes that don't have a mitochondrion. Can they exist in an environment without oxygen?

		Yes, yeasts can exist in an oxygen-poor environment. They will only be able to produce 2 net ATP via fermentation, but the absence of oxygen will not kill the organisms.
		No, the presence of oxygen will kill yeast because they will not be able to undergo fermentation.

Sugar is "quick energy" because provides energy to the cell directly, whereas carbohydrates like starch must be broken down before the body can utilize the energy.

True

False

Answer 1

Ans-1- RNA synthesis occurs at rough endoplasmic reticulum and catalysed by ribosomes.

Ans-2- animal cells does not have chloroplast, cell wall, vacuole.

Ans-3- endoplasmic reticulum, mitochondria and nucleus is present in animal cells not in bacteria (prokaryotes)

Ans-4- all the given statement about cell wall is true.

Ans-5- yes it is true that endoplasmic reticulum is in continuous with nuclear membrane.

Ans-6- mitochondria and nucleus both have the DNA

Ans-7- Correct order is-

-DNA synthesizes RNA BY TRANSCRIPTION

- mature mRNA is transported out of the nucleus.

RNA is translated into a ribosomes in rough endoplasmic reticulum.

- protein leaves RER in transport vesicle

-protein get processed in Golgi apparatus.

Ans-8- cellluet respiration produces 32 ATP while fermentation produces only 2 ATP (TRUE).

Ans-9- during ETC electron from NADH and FADH2 are used to pump H+ in inter membrane space of mitochondria.

Ans-10- energy is released in dephosphorylation of ATP .

Ans-11- O2 is the final electron acceptor and ETC is incomplete without it.

Ans-12- yes, in absence of O2 yeast produces only 2 ATP by fermentation

Ans-13- true sugar Is the ultimate form of any polymers that can be oxidized (True).
