What is the Structural and Functional Unit of any complex organism CORRECT
ANSWERS Cell
Characteristics of Healthy Cells CORRECT ANSWERS -Take in only the nutrients
needed to function properly
-Grow to a fairly uniform size and shape
-Multiply only when needed or directed to
-Don't infringe on each other's space
-Communicate and cooperate with each other for the good of the whole organism
Characteristics of Unhealthy Cells CORRECT ANSWERS -Take in all the nutrients they
can get, thereby depriving surrounding cells of vital nutrients
-Keep growing beyond their normal preprogrammed size and shape.
-Multiply out of control
-Infringe upon and push into and damage surrounding healthy cells
-Cease to communicate and/or cooperate with other cells or the body as a whole. This
leads to a breakdown in the function and structural integrity of the tissue or organ
involved.
Cell Theory States.. CORRECT ANSWERS -Cells are the building blocks of plants and
animals
-All cells are produced by the division of pre-existing cells
-Cells are the smallest units that perform all vital physiological functions
-Each cell maintains homeostasis at the cellular level
-Homeostasis at higher levels, reflects combined, coordinated action of many cells
-The human body contains many different types of cells
Cytology CORRECT ANSWERS The study of structure and function of cells
Homeostasis CORRECT ANSWERS The property of a system (Cell, Tissue, Organ,
Organism) either open or closed, that regulates its internal environment and tends to
maintain a stable, constant condition.
A typical cell.. CORRECT ANSWERS -Is surrounded by extra-cellular fluid, which is the
interstitial fluid of the tissue.
-Has an outer boundary called a cell membrane
-Has many components including the cellular organelles. These organelles carry out all
the vital processes required for life.
-Must take in nutrients from the interstitial fluid; use those nutrients to create all the
substances needed to carry on life; secrete any products meant for use outside the cell;
as well as excrete all waste products
,Cell Membrane CORRECT ANSWERS The outer boundary of a cell
DNA CORRECT ANSWERS Is a sequence of chemical bases that essentially stores
information in a "code" that tells the cell what proteins to make
When unraveled, how far would the DNA in each cell stretch? CORRECT ANSWERS 2-
3 meters long
When unraveled, all of the DNA in a single body would stretch how far? CORRECT
ANSWERS From the Earth to the Sun and around 400 times
How many DNA are in the body? CORRECT ANSWERS Approximately 35,000 genes
that make up 300,000 different proteins
Gene Activation CORRECT ANSWERS Initiates with Ribonucleic Acid (RNA)
Polymerase binding to the gene. (RNA Polymerase is a large protein)
Transcription CORRECT ANSWERS The formation of Messenger Ribonucleic Acid
(mRNA) from DNA.
mRNA CORRECT ANSWERS Carries instructions from the nucleus to the cytoplasm.
What are the two types of organelles found in cells? CORRECT ANSWERS
Membranous and Non-membranous
Membranous Organelles are surrounded by CORRECT ANSWERS Lipid Membranes
Membranous Organelles also feature CORRECT ANSWERS -Endoplasmic reticulum
-Golgi Apparatus
-Lysosomes
-Peroxisomes
-Mitochondria
Non-Membranous Organelles are CORRECT ANSWERS not enclosed by a membrane
and always in touch with the cytosol.
Non-Membranous Organelles also consist of CORRECT ANSWERS -Cytoskeleton
-Microvilli
-Centrioles
-Cilia
-Ribosomes
-Proteasomes
, Cell Membrane CORRECT ANSWERS Provides isolation, support and protection;
controls movement of materials in and out of the cell; acts as a barrier between the cell
and its environment
Cell Wall CORRECT ANSWERS Provides support that allows them to grow tall;
provides protection; allows water, oxygen and CO2 to diffuse in and out of the cell
The ________ is the Border of the Country because it surrounds the cell CORRECT
ANSWERS Cell Membrane
The ________ is the City Wall in a medieval city because it is stronger than the Cell
Membrane CORRECT ANSWERS Cell Wall
The ______ is the solar energy panel of the cell because it uses sunlight to create
energy for the cell CORRECT ANSWERS Chloroplast
The _____ is the Lawns, Parks, Forest and Foliage of the cell because it is the cell
landscape and is found in any space where organelles aren't. CORRECT ANSWERS
Cytoplasam
The _____ is the Steel Girders as they give each cell its distinctive shape and high level
of organization CORRECT ANSWERS Cytoskeleton
The ______ is the Highways and Road Systems because it its involved in so many of
metabolic processes CORRECT ANSWERS Endoplasmic Reticulum
The ______ is the Post Office/FedEx/UPS of the Cell because it sends proteins created
by the ER and ribosomes throughout the cell. CORRECT ANSWERS Golgi Apparatus
Contains the genetic info, 23 pairs in humans CORRECT ANSWERS Chromosomes
The _______ is the Recycling and Disposal Plants of the cell, as it is involved in
breaking down large molecules for either recycling or waste removal CORRECT
ANSWERS Lysosomes
The________ is the Cell's Energy plant as it converts glucose to ATP CORRECT
ANSWERS Mitochondria
The______ is the Brain of the Cell because it houses a majority of the genetic material
and controls all activity within the cell CORRECT ANSWERS Nucleus
Nuclear Membrane CORRECT ANSWERS Controls movement of materials in/out of
nucleus
Nucleolus CORRECT ANSWERS Inside Nucleus, Makes Ribosomes
