|
Autotrophs |
Use inorganic substance to make food |
|
|
Heterotrophs |
Get energy from eating organic substances |
|
|
Organic substances example |
Fats, sugar |
|
|
Inorganic substance example |
Carbon dioxide, water |
|
|
Photosynthesis reaction (chemical equation) |
6CO2 + 6H2O → C6H12O6 + 6O2 |
|
|
Photosynthesis word equation |
Carbon dioxide + water → glucose + oxygen |
|
|
What is chlorophyll and use? |
Is the green pigment, to trap sunlight |
|
|
. |
|
|
Chloroplast in epidermis,guard cells, mesophyll |
No,Yes,Yes. |
|
|
Epidermis |
Top and bottom layer Top protect the inner layer of cells in the leaf* and they also have the cuticle
*(from bacteria etc. So they can only enter through the stomata which is guarded).
|
|
|
Cuticle |
In the epidermis To stop water from evaporating from the leaf. |
|
|
Stomata |
Lower epidermis Guard by guard cells for gas exchange. Close at hot days (So water don't escape) |
|
|
Mesophyll |
Middle Top- Palisade (arrange in a fence formation) absorb light Bottom- Spongy (rounder, arrange loosely, air space) gas exchange |
|
|
Veins →xylem |
For carrying water |
|
|
Phloem |
For carrying sucrose and other things that leaf had made. |
|
|
Adaptation for CO2 |
Large surface area Thin |
|
|
Adaptation for water |
Xylem vessel close to the Mesophyll |
|
|
Adaptation for sunlight |
No chloroplast in epidermal (So sunlight can go to the Mesophyll layer) Palisade many chlorophyll in it |
|
|
Use of glucose |
-Energy (for respiration) -Stored as starch (not reactive, insoluble) -To make proteins (nitrate/ammonium and magnesium) -Convert to sucrose (less reactive)
|
|
|
Nitrates use and deficiency |
Proteins and yellow all |
|
|
Magnesium use and deficiency |
Chlorophyll, yellow except veins. |
|
|
Limiting factor |
If it's less it will stun the growth. |
