Flashcards in Chapter 1.1 Cell Structure Deck (21):
A unicellular organism has
one single cell
A multicellular organism is made up of
The ultrastructure of a cell is its
fine structure as revealed at high magnification
Chloroplasts are present in
green plant cells
The nucleus of a cells contains
genetic material and controls cell activities
The cell membrane controls
the entry and exit of substances into and out of the cell
Cell organelles are
compartments found in the cytoplasm and are the site of chemical reactions
Bacterial cells do not contain
The cell wall is for
support and shape and prevents plant cells from bursting.
Plant, fungal and bacterial cell walls have different
structures and are composed of different chemicals
The vacuole stores a
watery solution of salts and sugars and helps to support cells.
chlorophyll and are the sites of photosynthesis
Mitochondria are the sites of
aerobic respiration in cells.
Ribosomes are the sites of
protein synthesis in cells
In bacterial cells, plasmids hold
some of the genetic material (DNA) of the cell.
Aerobic respiration is the
release of energy from food by a cell using oxygen
structural carbohydrate of which plant cell walls are composed
Cytoplasm is a
jelly-like liquid containing cell organelles and the site of many chemical reactions.
Deoxyribonucleic acid; a substance in chromosomes that carries the genetic code of an organism
Mitochondrion is the
organelle that is the site of aerobic respiration and ATP production in cells
