Question 1

Question
The cell theory states that the cell is the mst basic unit of life, all organisms are made of cells and all cells come from cells. What makes the cell theory a scientific theory?
Answer
  • It is based on a scientific publication that is read by scientists worldwide.
  • It is based on the work of many scientists and leads to accurate predictions.
  • It is based on ideas that have been proven true and that are not subject to revision.
  • It is based on preliminary evidence but still needs to be confirmed with experiments.

Question 2

Question
Which of the following pairs incorrectly matches a cell structure with its function?
Answer
  • Cell Membrane : Protein Synthesis
  • Nucleus : Information (DNA) storage
  • vacuole : storage
  • chloroplast : energy conversion

Question 3

Question
Which of the following is a function on the Golgi Apparatus?
Answer
  • Storing genetic information.
  • Recycling waste products of the cell.
  • Providing a protective barrier.
  • Processing and storing proteins.

Question 4

Question
What are the folds in the Golgi Apparatus called?
Answer
  • cisternae
  • cillia

Question 5

Question
The cell membrane maintains homeostasis and is made of a combination of phospolipids and proteins.
Answer
  • True
  • False

Question 6

Question
Why is the cell membrane made of phospolipds and proteins?
Answer
  • The phospholipids prevent the membrane from dissolving and the proteins aid in semi-permeability.
  • Phospholipids have little oxygen and proteins cause enzyme catalyzed reactions.

Question 7

Question
What is the function of the ribosome?
Answer
  • To make proteins.
  • To make RNA.
  • To adhere to the Rough Endoplasmic Reticulum and adhere itself to the nucleus.

Question 8

Question
What is the function of lyosomes?
Answer
  • To transport the proteins
  • To carry out the waste of a cell.

Question 9

Question
Prokaryotic means...
Answer
  • primitive nucleus
  • True nucleus

Question 10

Question
What are chromosomes?
Answer
  • Long, thread-like bodies clearly visible during mitosis. Composed of DNA. Linear genes.
  • Genetic Archetypes.
  • The central focus of a cell.

Question 11

Question
What invention was an early step in the discovery of cells?
Answer
  • Microscope
  • Cell Theory

Question 12

Question
Which of the following is NOT a component of the cell theory?
Answer
  • All Living things are made of one or more cells
  • The cell is the smallest unit of life
  • All new cells come from preexisting cells
  • All cells contain cell walls

Question 13

Question
Which organism creates the energy required by cells?
Answer
  • Mitochondria
  • Chloroplast
  • Nucleus

Question 14

Question
What organelle creates proteins?
Answer
  • Ribosomes
  • Nucleus
  • Cell Membrane

Question 15

Question
Which organelle processes and transports proteins?
Answer
  • Golgi Apparatus
  • Lyosomes

Question 16

Question
Which organelle contains digestive enzymes to break down foreign invaders?
Answer
  • Lyosomes
  • Golgi Body
  • Cell membrane

Question 17

Question
Which organelle is a network of fibers that criss‐cross to support a cell from the inside?
Answer
  • Cytoskeleton
  • Cytoplasm

Question 18

Question
Which organelle performs photosynthesis to make sugar?
Answer
  • Mitochondria
  • Chlorophyll
  • Chloroplast

Question 19

Question
Which organelle is thought to help with cell division in animal cells?
Answer
  • Centriole
  • Golgi Apparatus

Question 20

Question
Which cell part is the internal fluid found in all cells?
Answer
  • Endoplasmic Reticulum
  • Cytoplasm
  • Cytoskeleton

Question 21

Question
Which organelle holds DNA and chromosomes?
Answer
  • Nucleolus
  • Neutrons

Question 22

Question
The Rough Endoplasmic Reticulum is studded with ribosomes and is often the site of protein synthesis.
Answer
  • True
  • False

Question 23

Question
How does form fit function apply to cytology?
Answer
  • Neurons are long and thin as they typically connect to one another to perform tasks.
  • Red blood cells are typically small and have large vacuoles and more proteins in the cell membrane so that they can hold and transport oxygen and nutrients.
  • Plant Cells have cell walls to protect them from nature as they are exposed.
