100% VERIFIED ANSWERS LATEST UPDATED
What is the basic organizational unit of all living things? - ANSWER the cell
What is one thing that all cells have in common? - ANSWER a cell membrane
What is a membrane comparable to? - ANSWER a semi-permeable plastic pag
What is the membrane composed of? - ANSWER phospholipids
What are transport holes? - ANSWER proteins that help certain molecules and ions
move in and out of the cell
What is cytoplasm? - ANSWER the fluid that fills the cell; aka cytosol
What are organelles? - ANSWER groups of complex molecules that help a cell
survive; the larger the cell the more organelles needed
What do all cells contain? - ANSWER DNA and RNA
What can all cells do? - ANSWER synthesize protein
What does each cell of an organism consist of? - ANSWER nucleic acids,
cytoplasm, and a cell membrane
What makes the mitochondria and chloroplasts unique? - ANSWER they are
specialized organelles that have specific functions within the cell
How do single-celled organisms differ from multicellular? - ANSWER
single-celled organisms contain all of the components necessary for life, while
multicellular organism cells can be specialized
How does life begin on the cellular level? - ANSWER life begins as a single cell by
either asexual or sexual reproduction
How are cells grouped? - ANSWER in tissues
How are tissues grouped? - ANSWER in organs
How are organs grouped? - ANSWER in systems
,What is considered a complete individual? - ANSWER an organism
What are ribosomes involved in? - ANSWER synthesizing proteins from amino
acids
How many ribosomes are in a single cell? - ANSWER numerous and take up about
one-quarter of the cell
Where are ribosomes located in the cell? - ANSWER some are mobile and some
are embedded in the endoplasmic reticulum
What does the Golgi apparatus (Golgi complex) do? - ANSWER synthesizes
materials such as proteins that are transported out of the cell
Where is the Golgi apparatus (Golgi complex) located? - ANSWER near the
nucleus
What does the Golgi apparatus (Golgi complex) consist of? - ANSWER layers of
membranes
What are vacuoles? - ANSWER sacs are used for storage, digestion, and waste
removal
How are vacuoles presented in different cells (plant/animal)? - ANSWER plant:
one large vacuole
animal: small, sometimes numerous vacuoles
What is a vesicle within the cell and what does it have? - ANSWER it is a small
organelle and has a membrane
What does a vesicle in the cell do? - ANSWER performs varying functions
including moving materials within a cell
What does the cytoskeleton of the cell consist of? - ANSWER microtubules
What does the cytoskeleton of the cell do? - ANSWER shape and support the cell
What are microtubules apart of? - ANSWER the cell cytoskeleton
What do microtubules do? - ANSWER support the cell
, What are microtubules made of? - ANSWER protein
What is cytosol? - ANSWER liquid material in the cell
What makes up the cytosol? - ANSWER mostly water, but also contains some
floating molecules
What does the term cytoplasm refer to? - ANSWER cytosol and the substructures
(organelles) found within the plasma membrane, but not within the nucleus
What does the cell membrane (plasma membrane) do? - ANSWER defines the cell
by acting as a barrier, helps keep cytoplasm in and substances located outside the
cell, and determines what enters and exits the cell
What are the two types of endoplasmic reticulum? - ANSWER smooth and rough
What distinguishes rough ER? - ANSWER ribosomes on the surface
What distinguishes smooth ER? - ANSWER does not have ribosomes on the
surface
What is endoplasmic reticulum? - ANSWER a tubular network that comprises the
transport system of a cell
Where is the endoplasmic reticulum located? - ANSWER it is fused to the nuclear
membrane and extends through the cytoplasm to the cell membrane
