Chapter 3 -- Part 2: Cells
The cell has a flexible boundary.
In one or two sentences, describe the differences between a plant cell in a leaf with full exposure to the sun and one in the shade.
The rough endoplasmic reticulum can be used to export lysosomes from the cell.
The pathway of the glycoprotein from the ER to the outside of the cell can be described in two or three sentences.
The cellular characteristics of prokaryotes and eukaryotes can be compared.
In contrast to this, the motion of a particular molecule with respect to another molecule is being described.
The energy requirement is indicative of active transport.
Water leaves the cell if the solute concentration is higher outside than inside.
The collapse of the cell is caused by this.
Since the motion of the molecule is random, there are bound to be some moving against the concentration.
Plant cells do not have the cholesterol that animal cells do.
Both plants and animals have ER cells with ribosomes.
Phospholipids are not found in cell walls.
peptidoglycans are found in the cell walls ofbacteria, while Chitin is found in the cell walls of fungi.
The solute cannot be passed through the tubing.
The bag will gain weight because of the water in it.
Answer choice A refers to the movement of water and answer choice B refers to the movement of the solute.
The water in the beaker is hypotonic and the solution in the bag is hypertonic when compared to their solute concentrations.
The tube can't hold sucrose since it can't pass through the membrane.
Water will diffuse down the concentration gradient.
The beginning concentrations of water in the tube and beaker are both 100%.
Water will move from the tube to the beaker.
The beaker level will rise and the water level in the tube will fall.
The large surface area of the reticulum provides a lot of space for ribosomes and the production and modification of proteins.
The number of saturated and unsaturated fatty acids in the phospholipids has an influence on the flexibility of the plasma membrane.
The bend in the double bonds of the unsaturated fatty acids increases the separation of the phospholipids, which increases the flexibility of the membranes in response to cooler temperatures.
After a ribosome on the ER produces a ribosome on the ER, the ER packages the glycoprotein into a vesicle.
The Golgi apparatus may undergo additional modification after the glycoprotein is transported to it.
The modified glycoprotein is packaged into a vesicle that transports it from the Golgi apparatus to the plasma membrane, where it is exported by exocytosis.
The bilayer is composed oflipids.
A molecule of phospholipid is made up of two fatty acids and a phosphate group.
The glycerol-phosphate head is a part of the molecule that is hydrophilic.
The heads of thelipids are pointing to the outside and the tails are pointing to the inside.
The barrier to most molecules is the plasma membrane.
The cell wall in plants, fungi, andbacteria is created by the deposits of polysaccharides on the outside of the membrane.
The cell wall supports the cell.
In animals cells, cholesterol molecule are embedded in the phospholipid bilayer.
The fluid mosaic model of the plasma membrane is a highly flexible lipid boundary impregnated with various other molecules.
The plasma is impermeable to water.
O2 and CO2 can be seen through the membranes.
The movement of larger molecule is regulated by a small group of genes.
There are many kinds of the same thing.
Some dissolved substances can be passed through channel proteins.
Transport proteins transport substances.
The matrix in animal cells is made up of a mixture of glycoproteins and glycolipids.
The inside of the cell is where hormones are transmitted.
Various substances can be exported.
In exocytosis, substances are packaged in vesicles.
Their contents are released to the outside once they merge.
Food and other substances can be imported by endocytosis.
In endocytosis, the substance is encased in a vesicle.
When a question has more than one part, you should separate your answers.
You need to separate your answer into two separate parts.
They both have some of the same things.
Many prokaryotes have a cell wall similar to the cells of plants and fungi.
In the second part of your answer, describe how prokaryotes and eukaryotes are different.
Indicate that the prokaryotic flagella do not contain micro organisms, and that the prokaryotic ribosomes are smaller than those of eukaryotes.
The cell walls ofbacteria and archaea containpeptidoglycans, but not the polysaccharides found in the cell walls of plants and fungi.
This is the first part of the question.
Explain each cell organelle's function in the first part.
In the second part, explain that the biochemical activities are separated from the metabolic functions.
Explain how the channels among layers of reticulum create compartments.
The ER and Golgi bodies have packaging relationships.
