4、A plant cell is placed into a beaker that contains a sucrose solution. The setup is shown in the diagram below.

正确答案

Which of the following is correct about what will occur and gives themost accurate reason for that occurrence?

(A) The cell will shrink because the water potential (Ψ) is greater inside the cell.

(B) The cell will shrink because the water potential (Ψ) is greater outside the cell.

(C) The cell will swell because the water potential (Ψ) is greater inside the cell.

(D) The cell will swell because the water potential (Ψ) is greater outside the cell.

5、Below is an illustration of a plasma membrane transporting two substances: sucrose and protons (H+).

Which of the following statements is supported by what is shown in the illustration?

(A Sucrose is diffusing down its gradient through a channel, but only in the presence of protons that are also diffusing in the same direction.

(B) Sucrose is diffusing down its gradient through a channel, but only in the presence of protons that are being pumped against a gradient.

(C) Sucrose is being carried against a gradient, but only while protons are diffusing down a gradient.

(D) Sucrose and protons are simultaneously being pumped against their gradients by a membrane pump.

6、Which of the following is correct about microtubules?

(A) They consist of actin fibers.

(B) They assist in the formation of pseudopods in amoeboid cells.

(C) They make up flagella in paramecia.

(D) They assist in the formation of the cleavage furrow in animal cells during cell division.

7、Below is an illustration of an important cell organelle.

Which of the following statements correctly describes this organelle and what is occurring in the figure?

(A) This is a rough endoplasmic reticulum that is producing proteins in attached ribosomes.

(B) This is a smooth endoplasmic reticulum that is producing proteins in attached ribosomes.

(C) This is a Golgi body that is packaging material, sent from the endoplasmic reticulum, near the trans face.

(D) This is a Golgi body that is packaging material, sent from the endoplasmic reticulum, near the cis face.

8、Which of the following is false about cytoskeletons?

(A) Centrosome which makes spindle fibers is made up of two centrioles.

(B) Pseudopods that allow ameba to move is an example that is related with microfilaments.

(C) Flagella are not made of microtubules when present in prokaryotes.

(D) Cilia and spindle fibers consist of 9 pairs of microtubules organized around 2 singlet microtubules

9、What decides either it is passive transport or active transport?

(A) Did solute move?

(B) Was the energy (ATP) used?

(C) Was there any movement of solvent?

(D) Was the movement random?

10. Which of the following is not a stage of cell signaling ?

(A) Transduction

(B) Reception

(C) Transformation

(D) Response

11、STRUCTURE AND FUNCTION OF THE CELL

A major theme in biology (and therefore a common free-response question topic) is that function dictates form and vice versa. As a result, one would expect that all cells do not look alike. And they do not. The nerve cell, whose purpose is to send electrical impulses, is long and spindly. Cells that store fat are rounded, large, and distended. Cells that make up a tough peach pit resemble square building blocks.

Read the paragraph, then infer and pick the nerve cell

(A) 1

(B) 2

(C) 3

(D) 4

12、Which of the information below are correct about the cells?

(A) All cells have only one mitochondria.

(B) Cell wall can be found both in animal cells and plant cells.

(C) Ribosome function as a protein factories

(D) Endoplasmic Reticulum assist in the synthesis of glucose.

13、Which of the following organelles contain an outer double membranes and inner series membranes called 'cristate' in them?

(A) Mitochondria

(B) Lysosome

(C) Chloroplast

(D) Endoplasmic Reticulum(ER)

14、Which of the following initiates a signal transduction pathway that leads to a response in a cell?

(A) Cyclic Amp is formed in the cytoplasm.

(B) A transmembrane receptor changes its conformation.

(C) A kinase transfers a phosphate group from ATP to another molecule inside the cell.

(D) An ion channel opens.
