RATED A+
Protoplasm, Nucleus, and plasma membrane - The basic components of a typical cell
a viscous, translucent, water material - Protoplasm is
Protoplasm - The essential component of plant and animal cells
a high percentage of water, inorganic ions (potassium, sodium, magnesium, and calcium), and
naturally occurring organic compounds (proteins, carbohydrates, and lipids) - Protoplasm
contains
1. Control acid-base balance
2. Control the amount of intracellular water - Special functions ions perform within the cell
Ions that have become dissociated into a negative or positive charge - Electrolytes are
The protoplasm of the cell nucleus - Nucleoplasm is
Reproduction - The role or function of the Nucleoplasm
Cytoplasm - The protoplasm of the cell body
Cytoplasm - Converts raw materials to energy
Nucleus - Cytoplasm surrounds the...
Cytosol, Organelles, and Inclusions - Cytoplasm contains
a viscous, semitransparent fluid consisting of 70% to 90% water; containing proteins, salts, and
sugars - Cytosol is
The metabolic units of the cell, performing specific functions to maintain the life of the cell -
Organelles are
1. Mitochondria
2. Ribosomes
3. Endoplasmic Reticulum
4. the Golgi Apparatus
5. Lysosomes
6. Peroxisomes
7. Cytoskeletal Elements
,8. Centrosomes - Organelles include
Mitochondria - threadlike structures within the cytoplasm that provide most of the body's
adenosine triphosphate (ATP)
Ribosomes - the sites of protein synthesis
an extensive network of membrane-enclosed tubules in the cytoplasm - Endoplasmic Reticulum
is
Proteins - Rough ER produces
lipids - Smooth ER produces
modifies concentrates and is associated with the formation of proteins and other substances -
Golgi apparatus function
Intracellular digestion - Lysosomes take part in
oxidases capable of reducing oxygen to hydrogen peroxide and hydrogen peroxide to water -
Peroxisomes contain
form a network of protein structures - Cytoskeletal elements
centrioles - Centrosomes contain
cell division - Centrioles take part in
nonfunctioning, commonly temporary, units - Inclusions are
glycogen in liver cells; melanin in epithelial cells - Examples of inclusions
The cytoplasm of the cell - Most synthesizing activities occur in
Nucleus - The control center of the cell
Cell growth, metabolism, and reproduction - Nucleus plays a role in
deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) - The nucleus contains
a large molecule composed of two long, twisted chains of phosphate, sugar molecules
(deoxyribose), purines, and pyrimidines - DNA is
the chromosomes of the cell - DNA is found in
genetic information...the blueprint for protein synthesis - DNA carries...and provides...
, a complex polynucleotide that controls protein synthesis; it serves as the genetic material for
many viruses - RNA is
the cytoplasm and nucleus - RNA is found in
a dark-staining body within the nucleus that lacks membranes and contains ribosomal RNA and
proteins - The Nucleolus is
one or more nucleoli - The Nucleus may contain
Ribosomes - The nucleus produces
a semipermeable membrane; only 7 nanometers to 8 nanometers thick, and is a double layer of
phospholipids with protein molecules - The Plasma Membrane is
the cell's external boundary, separating it from other cells and from the external environment. -
Function of the Plasma Membrane
division - Cells reproduce through
Because all tissues increase in size during childhood - Why do more cells undergo division in a
growing child rather than in an adult?
mitosis and meiosis - Cells divide by
the equal division of nuclear material - Mitosis (karyokinesis) is
division of the cell body - Cytokinesis is
2 exact duplicates of the original cell - Mitosis results in
4 phases (prophase, metaphase, anaphase, telophase) - Mitosis occurs in
the period between two mitotic cycles; the cell prepares for division and enlarges - Interphase is
No - Is interphase a phase of mitosis?
Chromosomes and DNA - ...are replicated during interphase
Chromatin...nuclear membrane - ....is diffused and the...remains intact during interphase
Chromosomal material - Chromatin
the centriole pairs in the nucleus move to opposite ends of the cell; the diffused chromatin
condenses, forming bars of chromosomes - Prophase
