Resource Aquisituon Plants

Question 1

Water comes through the plant through what. What is this process called that’s one way?

Answer 1

Through the root system to the shoot system and evaporates through the leaves. This is called transportation goes through its own system of tubes called xylem

Question 2

Sugar in plant goes?

Answer 2

Double sided up and down. But usually flows from a sugar source to a sugar sink or a place in the plant that needs sugar

Question 3

What are the primary sugar sources in plants

Answer 3

Leaves and travels through the phloem

Question 4

O2 and CO2 cone out and in

Answer 4

Carbon is taking in by photosynthesis and is fixed into organic material. This process is carbon fixation.

Through photosynthesis oxygen leaves the leaves and cones in through the roots

Question 5

What organelle foes photosynthesis

Answer 5

Chloroplast

Question 6

Complete oxidation of glucose

Answer 6

You use the glucose as efficiently as possible to get the most energy out of it

Question 7

Glycolysis

Answer 7

Incomplete oxidation that gives you some energy and pyruvate

Question 8

Cellular respiration

Answer 8

Plants have this as well in the mitochondria that maximizes atp

Question 9

In the root system why does CO2 come out and o2 go in

Answer 9

Because the plant is in the dark. The complete oxidation of glucose is used and cellular respiration occurs to gain energy and release CO2 and water

Question 10

Phyllotqxy

Answer 10

The way in which leaves are arranged

Leaves are arranged to maximize the sunlight absorption

Question 11

Are the cells in plants body all connected

Answer 11

Yes intercellular junctions called plasmodesmata

Question 12

Symplast

Answer 12

In the plasma membrane where the stuff is all connected

Question 13

Apoplast

Answer 13

Travels in the cell walls and doesn’t contain all the cytosol

Question 14

Transmemrane route

Answer 14

Start In either the apoplastic or symplastic route and transfer to the other.

Question 15

What are the types of transport across a cells membrane

Answer 15

Active
Passive
Vesicular

Question 16

Two majors of vesicular transport

Answer 16

Inward vesicular transport. Endsytosis

Exosytosis

Question 17

Passive transport requires

Answer 17

Energy that’s already there such as a gradient

Question 18

Active transport

Answer 18

An external source of energy

Moves things against a gradient. Moves things from a scarce position to a more plentiful position against the gradient

Question 19

Diffusion always happens

Answer 19

Down a gradient from more highly concentration to less concentrated area

Question 20

Simple diffusion through a transmemrane bilayer

Answer 20

Going through the phosphate head a lipid tail. Certain types of particles can go across the phospholipid bilayer. They must be small enough and non-polar

Question 21

Simple diffusion that requires the help of a protein is

Answer 21

Facilitated diffusion that uses a transport protein that’s part of the membrane

Question 22

Chanel proteins

Answer 22

Acts as a tunnel that acts for a specific particle based on the gradient. It is passive transport

Question 23

Carrier protein

Answer 23

Temporarily binds to a receptor and the protein changes it’s shape. Can be passive and the energy can be from the gradient

Can be active transport if the protein uses external energy to carry a particle

Question 24

Uniporter

Answer 24

Is a carrier protein that transport one type of particle

Question 25

Cotransporters

Answer 25

Can move two different kinds of particle at the same time possibly.

If they are moving in the same direction they are symporters
Antiporters is one is coming in and the other is leaving

Question 26

Pump

Answer 26

A carrier proteins that are being used for active transport

Question 27

Primary active transport

Answer 27

Energy is being used directly for the pump

Question 28

Secondary active transport

Answer 28

Using a gradient to drive a pump as the energy source to go against another particles gradient

Question 29

Osmosis

Answer 29

The movement of a solvent across a selectively permeable from a high concentration of solute to a low concentration in order to reach equilibrium

Question 30

Tonicity

Answer 30

The tendency for osmosis to occur through a cells membrane

Hypertonic
Hypotonic
Isotonic

Used to describe a cells environment

Question 31

Plasmolysis

Answer 31

When a plant cell loses water due to the its hypertonic environment and osmosis which causes the cell to peak from the cell wall

This process is damaging to the cell

Question 32

Hydroponics

Answer 32

Using aqueous solutions to grow a plant. You can replace solutes to see what plants need and what they can live without.

Botanist figure out elements plants need and don’t need through this in a chart

They need macronutrients and micronutrients

Question 33

Macronutrients make up

Answer 33

The macromolecules that make up life

Polynucleotides polypeptides
Polysaccharides lipids

Question 34

What two macromolecules have nitrogen in them

Answer 34

Polypeptides

Polynucleotides

Question 35

Amino acids have

Answer 35

Amino group NH3 so nitrogen

Question 36

What roles do micronutrients play in most organisms

Answer 36

They act as cofactors to bind to an enzyme to allow the enzyme to do its job

Question 37

Cation exchange

Answer 37

A plants roothair will release protons through their proton pump into a soil solution in order to neutralized a soil particle that is negatively charged and has cations attaches to it. The cations will then be bombarded and released from the soil particle for the plant to utilize as cofactors
