1The 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?
- AIt is based on a scientific publication that is read by scientists worldwide.
- BIt is based on the work of many scientists and leads to accurate predictions.
- CIt is based on ideas that have been proven true and that are not subject to revision.
- DIt is based on preliminary evidence but still needs to be confirmed with experiments.
2Which of the following pairs incorrectly matches a cell structure with its function?
- ACell Membrane : Protein Synthesis
- BNucleus : Information (DNA) storage
- Cvacuole : storage
- Dchloroplast : energy conversion
3Which of the following is a function on the Golgi Apparatus?
- AStoring genetic information.
- BRecycling waste products of the cell.
- CProviding a protective barrier.
- DProcessing and storing proteins.
4What are the folds in the Golgi Apparatus called?
- Acisternae
- Bcillia
5The cell membrane maintains homeostasis and is made of a combination of phospolipids and proteins.
- ARichtig
- BFalsch
6Why is the cell membrane made of phospolipds and proteins?
- AThe phospholipids prevent the membrane from dissolving and the proteins aid in semi-permeability.
- BPhospholipids have little oxygen and proteins cause enzyme catalyzed reactions.
7What is the function of the ribosome?
- ATo make proteins.
- BTo make RNA.
- CTo adhere to the Rough Endoplasmic Reticulum and adhere itself to the nucleus.
8What is the function of lyosomes?
- ATo transport the proteins
- BTo carry out the waste of a cell.
9Prokaryotic means...
- Aprimitive nucleus
- BTrue nucleus
10What are chromosomes?
- ALong, thread-like bodies clearly visible during mitosis. Composed of DNA. Linear genes.
- BGenetic Archetypes.
- CThe central focus of a cell.
11What invention was an early step in the discovery of cells?
- AMicroscope
- BCell Theory
12Which of the following is NOT a component of the cell theory?
- AAll Living things are made of one or more cells
- BThe cell is the smallest unit of life
- CAll new cells come from preexisting cells
- DAll cells contain cell walls
13Which organism creates the energy required by cells?
- AMitochondria
- BChloroplast
- CNucleus
14What organelle creates proteins?
- ARibosomes
- BNucleus
- CCell Membrane
15Which organelle processes and transports proteins?
- AGolgi Apparatus
- BLyosomes
16 Which organelle contains digestive enzymes to break down foreign invaders?
- ALyosomes
- BGolgi Body
- CCell membrane
17Which organelle is a network of fibers that criss‐cross to support a cell from the inside?
- ACytoskeleton
- BCytoplasm
18Which organelle performs photosynthesis to make sugar?
- AMitochondria
- BChlorophyll
- CChloroplast
19Which organelle is thought to help with cell division in animal cells?
- ACentriole
- BGolgi Apparatus
20Which cell part is the internal fluid found in all cells?
- AEndoplasmic Reticulum
- BCytoplasm
- CCytoskeleton
21Which organelle holds DNA and chromosomes?
- ANucleolus
- BNeutrons
22The Rough Endoplasmic Reticulum is studded with ribosomes and is often the site of protein synthesis.
- ARichtig
- BFalsch
23How does form fit function apply to cytology?
- ANeurons are long and thin as they typically connect to one another to perform tasks.
- BRed 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.
- CPlant Cells have cell walls to protect them from nature as they are exposed.
