Photosynthesis

Question 0

What are two adaptations for obtaining glucose?

Answer 0

Autotrophic nutrition(photosynthesis) & heterotrophic nutrition (ingestion , digestion)

Question 1

Nutrition

Answer 1

Obtaining and processing of food molecules. All living things obtain and process food molecules but the way they do it is different

Question 2

Autotroph

Answer 2

They are producers and can make their own food and change inorganic raw materials into organic products. Examples are plants and algae

Question 3

Heterotroph

Answer 3

Cannot make their own food, examples are animals

Question 4

Autotrophic nutrition

Answer 4

☀️. (Light energy ) —-> glucose. (chemical bond energy)

Question 5

Respiration

Answer 5

The release of energy from chemical bonds of glucose, energy is transferred to the chemical bonds of atp. Respiration is a life process but photosynthesis is not , it’s a type of nutrition Chemical energy(glucose) to chemical energy ATP

Question 6

Photosynthesis

Answer 6

Light energy to chemical energy

Question 7

How are the energy generating chemical reactions photosynthesis and respiration related?

Answer 7

Products made from photosynthesis are used as reactants in respiration and vice versa,…..their opposite

Question 8

Cuticle

Answer 8

Waxy covering of leaf for protection and prevents excess water loss

Question 9

Stomates(stoma ,stomata)

Answer 9

Open and close to allow for movement for water vapor and gas (CO2 and O2)

Question 10

Guard cells

Answer 10

Kidney shaped cells around stomates and regulate opening and closing by swelling with water when needed

Question 11

Palisade mesophyll

Answer 11

Where photosynthesis occurs and one or two cells thick. Lots of chloroplast

Question 12

Spongy mesophyll

Answer 12

Lots of air space to allow for gas exchange

Question 13

Plant transport

Answer 13

Veins”vascular bundle”, xylem,phloem

Question 14

Veins

Answer 14

Contains vascular tissue

Question 15

Xylem

Answer 15

Water and materials UP ONLY

Question 16

Phloem

Answer 16

“Ph”food. Nutrients ALL DIRECTIONS

Question 17

Path of water takes up through a plant

Answer 17

Into roots-through xylem-to leaves-out through stomates when guard cells are opened

Question 18

Root hairs

Answer 18

Increase surface area for greater absorption

Question 19

Root pressure

Answer 19

Osmotic pressure in xylem of a root

Question 20

Capillary action

Answer 20

Tendency of liquid to rise inside narrow tubes

Question 21

Transpirtation

Answer 21

Evaporation of water off leaves

Question 22

Transpiration pull

Answer 22

Chief process that moves water through xylem

Question 23

Pigments

Answer 23

Substances that absorb certain wavelengths of light energy and reflect others example is chlorophyll it absorbs red orange blues and violets but reflects green and yellow

Question 24

Pigments founded in plants

Answer 24

Carotenes-orange Xanthophyll -yellow

Question 25

Chromatography

Answer 25

Used to separate pigments by separating the mixture by solubility or ability to dissolve. The more sociable the better to dissolve and it will move farther up the paper, less solvable materials will adhere better

Question 26

Light

Answer 26

Travels in waves(photons,white light)

Question 27

Photons

Answer 27

Packages of light energy

Question 28

White light

Answer 28

Made of a spectrum of colors

Question 29

What is the photosynthesis formula ?

Answer 29

CO2+H2O+Sunlight --> O2+H2O+C6H12O6 (organic raw materials). (Organic c+h). Reactants Product

Question 30

Photosynthesis summary

Answer 30

Energy= sunlight --> chemical bonds in glucose. Materials used(reactants)= carbon dioxide and water and sunlight. Materials produced(product)= glucose(organic) and water/oxygen(waste product) Time frame= daylight hours Location(organelle)= chloroplast Importance= stores energy from sun and made atp available to other organisms

Question 31

Oxidation

Answer 31

Any chemical change in which an atom or molecule loses an electron and hydrogen and phosphate Leo

Question 32

Reduction

Answer 32

Any chemical change in which and atom or a molecule gains an electron and hydrogen and phosphate Ger

Question 33

Redox

Answer 33

Oxidation and reduction occurring at the same time

Question 34

Biochemical pathway

Answer 34

Sequence of chemical reactions that leads to a particular results. Reactions require enzymes and enzymes require coenzymes

Question 35

Coenzymes act as hydrogen acceptors

Answer 35

Can accept H+ NADP + H --> NAPPH. Gain H....GER...reduced

Question 36

Light dependent reaction

Answer 36

Location- grana. Water is split(photolysis) and oxygen is released into the atmosphere. NADPH and ATP are made to be used in light independent reaction

Question 37

Light independent reaction or Calvin cycle or carbon fixation

Answer 37

Location - stroma. Enzyme Rubisco converts inorganic CO2 into organic glucose by combining two PGAL molecules (a 3 C molecule)
