Homework 3 Chapter

Question 1Centrioles

carry on cellular respiration.

are found in plant cells.

consist of a 9 + 2 pattern.

are composed of microtubule triplets.

are composed of actin.

Question 2Considering that minute differences in organelle structure are enough to provide selective toxicity, which of the following cell organelles would be a good target for an antibiotic so it doesn't attack your cells?

DNA

cytoplasm

plasma membrane

ribosomes

endoplasmic reticulum

Question 3During photosynthesis, solar energy is converted to chemical energy by the chloroplasts. The process is represented by

carbohydrate + oxygen → carbon dioxide + water + energy

solar energy + carbon dioxide + water → carbohydrate + oxygen

solar energy → carbohydrate + oxygen

solar energy + oxygen + water → carbohydrate + oxygen

carbohydrate + carbon dioxide → oxygen + water + energy

Question 4If the chloroplast is the result of endosymbiosis, what membrane of the chloroplast represents the plasma membrane of the original prokaryote?

the inner chloroplast membrane

the outer chloroplast membrane

crista

thylakoid membrane

granum

Question 5Ribosomal RNA is produced in the

ribosomes.

smooth endoplasmic reticulum.

rough endoplasmic reticulum.

Golgi apparatus.

nucleolus.

Question 6Surface-area-to-volume ratios indicate

a chicken egg is one cell thus demonstrating the upper limit for metabolizing cell size.

as cells get larger, their surface area actually decreases.

as cells get larger, their surface area gets larger but at a slower rate than the volume increases.

cells must exceed a certain minimum size.

that the largest cells have a less proportionate need for food intake and waste removal.

Question 7The nucleolus

contains DNA and is found in the cytoplasm.

contains DNA and is found in the nucleus.

contains RNA and is found in the cytoplasm.

contains ribosome subunits and is found in the cytoplasm.

contains RNA and is found in the nucleus.

Question 8Tissues that produce large amounts of secretions, such as the gastric glands of the stomach, contain cells with large numbers of

lysosomes.

nucleoli.

Golgi apparati.

centrioles.

mitochondria.

Question 9When a lysosome fuses with a vacuole,

its contents are digested.

they both return to the Golgi apparatus.

protein synthesis begins.

they both disappear.

division begins.

Question 10Which of the following is not true concerning the cell theory?

               

Schleiden determined that all plants are made of cells.

Hooke observed the cells of cork.

Virchow asserted that all cells come from preexisting cells.

Schwann researched animal tissues and discovered that they were all made of cells.

Leeuwenhoek first used the term "cells."
