QUIZ 1.2 Flashcards
Photosynthesis occurs in the _____ which
are only present in plant and ___.
chloroplasts, algal cells
The house the cellular respiration of
the cell.
mitochondria
___, ___, and ___ are the
digestion centers of the cell.
Lysosomes, vacuoles, and peroxisomes
___ work together with the endoplasmic
reticulum to synthesize, store, transport, and release
molecules.
Golgi Body
Eukaryotic cell houses DNA in a ____.
Nucleus
___ allow the exchange of materials
through the nuclear envelope.
Nuclear pores
The smooth endoplasmic reticulum synthesizes ___
Lipids
Rough endoplasmic reticulum synthesizes ___.
Proteins
- Ancestral prokaryote
- infolding of plasma membrane
- endosymbiosis
- ancestral eukaryote
Endosymbiotic theory
Genetic control of the cell (2)
(nucleus and ribosomes)
Endomembrane system (5)
(endoplasmic reticulum, Golgi bodies, lysosomes, peroxisomes, and vacuoles)
Energy houses (2)
(mitochondria and chloroplast)
● This is a prominent, usually oval structure in a eukaryotic cell.
● It is located in almost the center of the cell.
Nucleus
Parts of the nucleus:
- Nucleoplasm
- Nuclear Envelope
- Nuclear Pore
____ is the semifluid matrix
Nucleoplasm
____ separates the nucleus from the cytoplasm
Nuclear envelope
____ Permit the passage of ribosomal subunits and mRNA out of the nucleus into the cytoplasm
Nuclear pores
___ are the organelles that use instructions from the
nucleus, written in mRNA, to build proteins or to synthesize.
Ribosomes
2 types of ribosome:
- Free
- Bounded
___ are found in the cytosol.
Free ribosomes
are attached to the outside of the endoplasmic reticulum or nuclear envelope.
Bound ribosomes
have thousands of ribosomes attached to the outer surface which give his organelle a “rough appearance. Their main role is to produce proteins.
Rough ER
does not have attached ribosomes. This organelle produces lipids.
Smooth ER
These serve functions similar to a warehouse and processing center, garbage center, processing products of the ER.
Golgi Bodies / Golgi Apparatus
Digestive systems, transfer to ER if use, if not to Golgi Body
Lysosomes
- Assist, digest toxic materials, detoxify the cell
- These contain enzymes and serve
as metabolic assistance to organelles and specialize synthesizing & breaking down lipids
Peroxisomes
This is known as the “powerhouse of the cell”
Mitochondrion (singular)
This is only to plant and algae cells, This organelle perform photosynthesis
Chloroplast
These serve as storage of water, organic nutrients, variety of salts, sugar & some weak acids.
Vacoules
in chloroplasts. Croma means ___ (cromatil)
green
a foreign part of the cell are ___&___
chloroplasts and mitochondria
Pro means ____, Karyon means ____
Nothing, Nucleus or False nucleus
eukaryon means
True nucleus
___ is a single strand
DNA
includes 1 chromosome ___, includes more than 1 ___
Prokaryote, Eukaryote
Reproduction of body cells
Mitosis
Production of sex cells
Meiosis
in Prokaryotic fission means to __ and Fussion means to ___
seperate, combine
