Responsible for intracellular transit within the cell? - CORRECT ANSWERS
Cytoskeleton (microtubules and microfilaments), Vesicles
Responsible for intercellular transit within the cell? - CORRECT ANSWERS Cell
wall, plasma membrane
Where does power come from in the cell - CORRECT ANSWERS Chloroplasts,
mitochondria (produces mostly ATP), break down of storage organelles.
Where are things stored in the cells? - CORRECT ANSWERS
Plastids(amyloplasts), Vacuoles (protein storage vacuoles), oil bodies
Where does waste in a cell go? - CORRECT ANSWERS Vacuoles, apoplast,
crystals, entire cell by cell death
What order are the zones of root growth? - CORRECT ANSWERS Closest to the
tip is division zone, middle is elongation zone and following that is
differentiation zone. some overlap may occur.
Order of interphase phases - CORRECT ANSWERS G1, S, G2
Order of Mitosis Phases - CORRECT ANSWERS interphase, prophase,
metaphase, anaphase, telophase, cytokinesis

Cell shapes - CORRECT ANSWERS Isodiametric, polyhedral, elongated,
branched
Different cell types can have what kind of cytoplasm? - CORRECT ANSWERS
Dense or vacuolated
Different ways cells can be distributed around the plant? - CORRECT ANSWERS
Specialized cells are only found in one tissue, Generalists are found in many
tissues
How are new cell walls created by cell division? - CORRECT ANSWERS Form
during cytokinesis, cell plate expands outwardly until hits parental wall, once
cell plate fuses with parental wall it becomes cell wall
How does a new cell grow and specialize into interphase? - CORRECT ANSWERS
Cell growth occurs during the interphase through the synthesis of needed
proteins for the cell's subsequent stages, as well as the replication of DNA for
cell division.
Primary cell wall from outside to inside - CORRECT ANSWERS PM, Cell wall,
plasmodesma, middle lamella

Pectin's role in cell wall - CORRECT ANSWERS Gives cell wall some flexibility,
absorbs water allowing it to be mushier (attributing flexibility), padding
between cells helping them not get damaged
Hemicellulose crosslinks with what? - CORRECT ANSWERS Nearby Cellulose
microfibril
Atomic force microscope - CORRECT ANSWERS can produce images of
individual atoms on a surface, shows texture and is almost like it is feeling the
surface
Cellulose microfibril orientation determines what? - CORRECT ANSWERS Cell
shape
Role of Cellulose synthase in building a cell wall? - CORRECT ANSWERS They
are mobile and their trajectories are determined by microtubules, they make
cellulose microfibrils in the plasma membrane
Primary cell walls - CORRECT ANSWERS In all cells, thin and flexible, deposited
during cell expansion, hydrophilic
secondary cell wall - CORRECT ANSWERS not in all cells, deposited after cell
expansion, thick and rigid, can be multiple layers, formed internal to primary
wall

lignin in secondary cell wall - CORRECT ANSWERS Gives mechanical strength,
hydrophobic polymer, fills space between cellulose, since its hydrophobic it
improves water transport into xylem
What are pits? - CORRECT ANSWERS recessed cavities in the cell wall where
the secondary wall does not form
What is happening when pits form at primary pit field? - CORRECT ANSWERS
Plasmodesmata in primary cell wall gets clustered into primary pit field and
becomes pits in secondary cell wall, and the pit membrane is a primary wall
region where the pit field was
Primary tissues - CORRECT ANSWERS formed by primary growth, increase in
organ length, herbaceous plants, cells are supplied by primary meristems
Secondary tissues - CORRECT ANSWERS Formed by secondary cell growth,
increase in organ width, woody plants, cells are supplied by secondary
meristems
dermal tissue system - CORRECT ANSWERS Outermost layer of cells, controls
what goes in and out, protects from environment, often covered with waxy
hydrophobic cuticle
Dermal tissue cell types - CORRECT ANSWERS 1) Trichomes
2) unspecialized Pavement epidermis Cells
