Term
| What does cytoplasmic streaming facilitate? between what two things? |
|
Definition
| Faciliates transport of materials within cell and between cell and environment |
|
|
Term
| What is the function of the plasma membrane in regards to transport, the cell wall, and signaling. |
|
Definition
Transports material in and out of protoplast
coordinates synthesis and assembly of cell wall
receives and transmits signals
Better covered in chapter 4 |

Term
| Plastids -describe structure (3), what do they have to do with regards with DNA, and how do they divide |
|
Definition
stucture: double membrane with thylakoids and stroma inside
plastids "own" DNA and ribosomes
Divide by fission |
|
|
Term
| Chloroplasts - what are they a part of, what do they contain (3), what do they do (2). |
|
Definition
Part of plastids, contain chlorophyll, carotenoids, and temporarily store starch.
They are the site of photosynthesis and synthesis of other compounds |
|
|
Term
| What are the chromoplasts, leucoplasts, and proplastids a part of, and decribe them briefly. |
|
Definition
all part of plastids
- chromoplasts include carotenoids
- leucoplasts lack pigments and synthesize starch
- proplastids are undifferentiated plastids in meristematic cells.
|
|
|
Term
| Plastid developmental cycle: 7 steps (2 and 3 dont have a name) |
|
Definition
- proplastid (undifferentiated)
- starts differentiating
- continues to diff
- start seeing shit form still maturing
- mature chloroplast
- chromoplast stage
- amyloplast
know that the proplastid can also go to amyloplast, and chromoplast directly (still has to mature), instead of forming a chloroplast first. |

|
Term
| Mitchondria : what does it have, what is structure, how do they divide, and what do they do |
|
Definition
- have own DNA and ribosomes
- double membrane structure
- divide by fission
- site of cellular respiration
|
|
|
Term
| Vacuoles - what is structure, and what is function in regards to storage and other things (4) |
|
Definition
- Membrane bounded region filled with liquid (call sap)
- may be 90% cell volume in mature cells
- function: maintain tissue rigidity, store primary and secondary metabolites, store prigments, and may breakdown and recycle macromolecules

Term
| Components of cell wall, what are they and what are they made of/what do they do (3) |
|
Definition
- cellulose - made of carbs, most abundant organic compound on earth, framework interpenetrated by matric of noncelluloseic materials
- lignin - phenolic compound, second most abundant organic compound on earth
- cutin, suberin, and waxes - made of lipids

Term
| Cell wall: what does secondary cell wall have. What are three things in cell wall |
|
Definition
Secondary cell wall - more cellulose than primary
also has middle lamella and pit fields/pits |
|
|
Term
| Stone cells -what are they and where are they found |
|
Definition
| They are sclerieds from the pear flesh, have thick secondary walls |
