Parts Of A Plant Cell
Which statements correctly refer to the organic protoplasm:
- the chemicals of the protoplasm are synthesized within the cell - the instructions for synthesizing protoplasm come from DNA
What cell part is described below? - The organic materials between the membrane and nucleus, which contains a variety of tiny bodies, or organelles.
cytoplasm
The construction of the cell walls of all plants is similar.
False
The number of chromosomes within each species of plant or animal:
is constant
Chemical messages originate from:
DNA
Inherited physical traits are directly related to:
Genes
What cell part is described below? - Flattened membrane sacs and tubes that are believed to be centers for collecting and packaging cell structures and enzymes.
Golgi bodies
A chemical important in taking blueprint messages from DNA
RNA
Why is a cell analogous to an engineered watch?
- because it consists of numerous interdependent subunits - because coded information cannot arise from random processes
ATP is a:
- product of decomposition of starch - chemical associated with mitochondria - a form of chemical energy
The chemical structure of genes which control inheritance
DNA
DNA is an abbreviation for _________ acid.
Deoxyribonucleic
A chloroplast consists solely of a football shaped container of chlorophyll.
False
RIbosomes are made of RNA
False
What cell part is described below? - A feature of plants that gives shape and texture and provides support.
cell wall
What cell part is described below? - Green, football-shaped plastids that carry out the life-support system of photosynthesis.
chloroplast
What cell part is described below? - Major segments of DNA during cell division.
chromosomes
What cell part is described below? - A system of membranes that appears to be a factory for life processes and a cell communication system for chemical messages.
endoplasmic reticulum
The cell powerhouse
mitochondria
What cell part is described below? - Rod-shaped structures scattered throughout the cytoplasm that are involved with energy release.
mitochondria
A smaller, darker body found in the nucleus
nucleolus
What cell part is described below? - A concentration of the nucleic acid RNA, which is important in carrying chemical messages to other bodies in the cytoplasm.
nucleolus
What cell part is described below? - The cell headquarters and inheritance; controls and orders the activities of the cell.
nucleus
The microscopic assembly units or subsystems suspended in cytoplasm are generally called
organelles
The basic food produced by a plant is:
produced by chloroplasts
The transfer of information from the nucleus to organelles is accomplished by:
ribonucleic acid
Important in protein synthesis
ribosome
The known operational complexities of a cell make the phrase "__________" obsolete and misleading.
simple cell
Tissues which are normally difficult to discern with an optical microscope may be revealed by:
stain
The total energy production of a mitochondrion is enhanced by:
the large internal surface area
