Cell Structure and Functions Flashcards
building blocks of all living things
cell
carry out all chemical activities needed to sustain life
cells and tissues
are group of cells that have the same structure an they work together as a unit
tissue
the basic unit of life
cell
give the three main region of a cell
nucleus, cytoplasm, plasma membrane
it is the control center of the cell and contains the genetic material
nucleus
the three regions of the nucleus
chromatin, nucleolus, and nuclear membrane
DNA stands for?
deoxyribonucleic acid
serves as the barrier of the nucleus
nuclear membrane
nuclear membrane contains ___________ that allows of exchange of material in the cell
nuclear pores
it separates the nucleus to cytoplasm
nuclear membrane
nucleus contains one or more _________
nucleoli
site of ribosome production
nucleolus
composed of DNA and protein
chromatin
how many chromosomes does human have?
46 or 23 pairs
it is scattered throughout nucleus
chromatin
a chromosomal condition wherein characterized by an additional chromosome
trisomy
additional chromosome on the 21st pair
trisomy 21 or Down Syndrome
trisomy 18 is also called?
Edward syndrome
additional chromosome on the 13th pair
Patau syndrome
XXY or also known as?
Klinefelter syndrome
XXX or the triple X syndrome contains?
super female features
it serves as a regulator for molecules in and out of the cell and it is the barrier for cell contents
plasma membrane
water loving
hydrophilic heads
water fearing
hydrophobic tails
give the other materials in plasma membrane
protein, cholesterol, and glycoproteins
it is the site where most of the cellular activities happens
cytoplasm
three major elements of cytoplasm
cytosol, organelles, and inclusions
this are chemical substances which may not present depending on the type of cell
inclusions
these are parts of the cell that carry out specific functions to maintain the homeostasis
organelles
a semi transparent fluid which contains suspension for organelles
cytosol
