Unit 6: General
Pollination happens before, ____ and travels by _____
Fertilization, and wind+insects
Xylem is made of ____ cells
What is dead
Mineral ions are pumped into the cell, water follows by ________
osmosis
Nucleic Acid
In terms of living, a virus is?
Not alive
Maltose can be further broken down, into _______
glucose
Phloem is made of ______ cells
The two parts consist of the root hair cells, but also the root _________
epidermis
Size, relative to cells?
very small
Occasionally, viral DNA may be removed from host DNA and enter the _____ cycle
lyctic
____ stomata is expected on the bottom of the leaf
More
The XYLEM transport
What is water and dissolved minerals
In the _______ pathway water moves around the cells, through the cell walls (it does NOT pass through cell ????????)
apoplast, membranes
Capsid made of
protein
What are some reasons that there may be a decline in the number of cases of a disease over time?
Decrease in number of _______ (animal vectors)
Auxin activates?
Proton pumps in cells
Phloem includes ____ cells, and _________ cells.
Sieve tube, companion
Water follows the ______ pathway, or the _______ pathway. (Step II)
Symplast, apoplast
Few or No:
proteins
What distinguishes the lytic cycle of viruses from the lysogenic cycle?
The lysogenic cycle is when the virus’ genetic material is incorporated into the host cell’s DNA. The viral DNA is then replicated along with the host cell’s own DNA and is therefore present in new cells after host cell reproduction. The virus:
Attaches to specific host cell and injects DNA
Incorporates viral DNA with host cell DNA
Host cell replicates DNA and _________ _______
New cells contain copy of _____ ___
Occasionally, viral DNA may be removed from host DNA and enter the lytic cycle
reproduces normally,
Viral DNA
Cotyledons release ___, a plant hormone
Gibberellin
The PHLOEM transport direction is
What is, both ways
In the symplast pathway water moves through the inside of cells, water is taken into cells through membranes, moves in and out of vacuoles, and through _________ from cell to cell
plasmodesmata
No _______
cytoplasm
How could you tell by looking at an electromicrograph of a virus if it has already infected a host cell or not?
A virus that has already infected a host cell will no longer contain its ___________ inside the capsid once the ____/___ has been injected into the host cell. There may be a visible opening in the virus’s capsid / envelop where the genetic material exited.
Genetic information, DNA/RNA
