What is the study of cellular structure and function? - ANSWER: Cytology.
The ____ is the structural and functional unit of all living matter. - ANSWER: Cell.
The cell is encased by a _______. - ANSWER: Cell membrane.
Cell membrane is also called a what? - ANSWER: Plasma membrane.
What does the cell membrane do? - ANSWER: Seperates intracellular material form
extracellular material.
What are the functions of the cell membrane? - ANSWER: To hold the cell together,
and determine what substances are allowed to enter or leave the cell.
The cell membrane is semipermeable -- true or false? - ANSWER: True.
What makes up the cell membrane? - ANSWER: Phospholipids and protein and a
small amount of carbohydrates.
What do the protein molecules in the cell membrane do? - ANSWER: Provide
structural support for the membrane, act as binding sites for hormones, and create
pores through the lipid membrane.
How can substances move across the semipermeable membrane? - ANSWER:
Dissolve in the lipid portion, or cross the membrane by flowing through the pores.
Inside the cell is divided into two compartments: 1,2. - ANSWER: The nucleus and the
cytoplasm.
What is the nucleus? - ANSWER: The control center of the cell.
The nucleus is filled with a fliud substance called ______. - ANSWER: Nucleoplasm.
DNA containing structures are called what? - ANSWER: Chromosomes.
What is cytoplasm? - ANSWER: The gel-like substance found inside the cell, but
outside the nucleus.
, What does the cytoplasm contain? - ANSWER: Cytosol and organelles.
What is the mitochondria? - ANSWER: Tiny, slipper-shaped organelles.
What organ contains a lot of mitochondria? - ANSWER: The liver.
What is the "power plant" of the cell? - ANSWER: Mitochondria.
What does the mitochondria produce? - ANSWER: ATP.
What are ribosomes? - ANSWER: Cytoplasmic organelles involved with protein
synthesis.
Some ribosomes are attached to the ER and are called ______. - ANSWER: Fixed
ribosomes.
Ribosomes that float freely within the cytoplasm are _______. - ANSWER: Free
ribosomes.
What is the ER? - ANSWER: A network of membranes within the cytoplasm.
What are the two types of ER? - ANSWER: Smooth and rough.
What is the RER concerned with? - ANSWER: Protein synthesis.
What is the SER concerned with? - ANSWER: Synthesis of lipids, steriods, glycerides,
and glycogen.
What is the golgi apparatus? - ANSWER: A series of flattened membranous sacs.
What are lysosomes? - ANSWER: Membranous sacs containing powerful enzymes.
What do lysosomes do? - ANSWER: Break down intracellular waste and debris;
"clean house"
Lysosomes participate in the destruction of ingested bacteria, a process called
_________. - ANSWER: Phagocytosis.
The cytoskeleton is composed of threadlike structures called _______ and _______. -
ANSWER: Microfilaments and microtubules.
What does the cytoskeleton do? - ANSWER: Help maintain shape of the cell and
assists the cell in various forms of cellular movement.
What is the primary component of the cytoskeleton? - ANSWER: Microtubules.
