- What is the WORD EQUATION FOR PHOTOSYNTHESIS?
-
COW > GO
GO> WEC - What is the full word equation for Phot.?
-
Water + C02= Glucose + Oxygen
Glucose + Oxygen = Water + Energy + C02 - BIOMASS
- The Mass of the materiaaaals that PLANTS and ANIMALS are made of!
- What is the FIRST substance that plants make?
- GLUCOSE ( A type of Sugar)
- The glucose is...
- Changed into other substances!
- The mass of all the materials in a plant or animal is called the
- BIOMASS
- Plants need?
- Warmth and Minerals
- A plant can live without...
- SOIL (as long as there is water)
- Plants need ______ to make their OWN FOOD.
-
-Water
-CO2
- Most photosynthesis occurs in the
- PALISADE CELLSSSS
- A STOMA is...
- A space between the cells.
- List all the cells we learned about in a leaf.
-
- Epidermal Cells.
- Palisade Cells
- Guard Cells.
- Spongy Mesophyll Cells. - Epidermal cells have...
- NO CHOLORPLASTS.
- Why is the cuticle of a plant cell waxy?
- So that its waterproof, so it stops water from evaporating at the top of a leaf!
- What is chlorophyll?
- Chlorophyll is a green substance in LEAVES that ABSORBS LIGHT.
- Without light...
- There is no photosynthesis.
- Why does a root hair cell have tiny root hairs all over its surface?
- So that it covers a large surface area of the soil.
- Name the parts of a cell (root hair)
-
CYTOPLASM
CELL MEMBRANE
NUCLEUS
VACUOLE - Water goes into the ROOT HAIR CELLS by the process of....
- OSMOSIS (DIFFUSION OF WATER)
- Water helps by keeping plants..
- RIGID.
- Roots take in...
- DISSOLVED MINERALS IN WATER (NITRATES)
- Why is floding BAD for the plant?!
- Not enough Oxygen, suffocates :(
- Plants produce...
- OXYGEN.
- GLUCOSE CAN BE CONVERTED TO...
-
-PROTEINS
-MAKING STARCH
-FATS&OILS
-CELLULOSE CELL WALL
-SUGERS (EG FRUCTOSE) - Sucrose is the form...
- C02 + H20 > C6H12O6
- Some of the Glucose is used to
- RELEASE ENERGYYYYY
- What is the use of water in plants?
-
-Cell growth
-Firms cells
-Forming Fruits
-Cooling Leaves -
No Light > No photosynthesis...
- >No starch produced > Iodine stays YELLOW.
- Light > Photosynthesis>...
- >Produce starch > Iodine turns BLUE/BLACK.
- FOUR THINGS AFFECTING PHOTOSYNTHESIS:
-
1 LIGHT -more light, more phot.
2 WATER -little water, slows it down.
3 TEMPERATURE -Optimum temp 30c
4 CO2 LEVELS - Increases, increases growth. - WORD EQUATION FOR RESPIRATION
- SUGAR + OXYGEN > CARBON DIOXIDE + WATER + ENERGY
- The light energy needed for phot. is trappped by?
- CHLOROPHYLL.
- STARCH is needed to
- RELEASE ENERGY DURING RESPIRATION AND TO MAKE NEW MATERIALS.
- PLANTS NEED NITRATES TO MAKE...
- PROTEINS (REPAIR)
- Most photosynthesis happens at the
- TOP OF THE LEAF ^
- Respiration, rotting, and burning all release
- CO2
-
Humans are part of a complex _________
_ - FOOD WEB.
- Humans need to protect _______and the e________
- Food webs and the environment.
-
How do humans manage crop production?
-
-Using Fertilizers
-Using Irrigation
-Reducing Destructions!!! -
Human development can
a) harm the environment
b) help us dance
c) improve with the environment -
HARM THE ENVIRONMENT.
A
- HUMAN DEVELOPMENT can be SUSTAINABLE IF WEEE...?
-
PREVENT POLLUTION
PRESERVE HABITATS
MAINTAIN BIODIVERSITY - HUMANS > ___________ > _______-
- HUMANS > ANIMALS > PLANTS.
- Plants make food using
-
CO2
WATER
MINERALS
SUNLIGHT! - The Environment affects plant growth, how?
-
If there is no CO2, little water and little minerals, the plant is unhealty
-PESTS can be more likely to come
-WEEDS are more likely to grow
- Why do farmers use pesticide?
-
So they can produce
-more food and make more profit
-undamaged food, higher price - What is BIACCUMULATION?
-
It is when a disease is passed on.
PESTICIDES
-Get into nearby bodies of water
- Water plants and animals absorb the chemicals
- Small fish eat the tiny plants and animals and they store the chemical.
- Larger fish and animals eat the small fish and they store the disease.
- Chemical amount increases because larger animals eat larger amounts of the small food. - What do pests do?
- They eat FARMERS CROPS.
- A weedkiller is...
- A chemical that kills weeds.
- A weed is
- A fast growing plant that is growing where it is unwanted.
- Weeds take a lot of time and effort to remove.
- TRUE.
- ONLY GREEN PLANTS MAKE
- FOOD
- Word equation for plants making proteins?
- Glucose + Minerals>>>>Energy from Respiration>>>Amino ACIDS >>>>Energy from resp. >>>>PROTEINS
- What are the two types of FERTILIZERS?
-
-NATURAL (cow manure, made naturally, cheaper, organic farmer)
AND
-CHEMICAL (expensive, unnatural) - POLLUTION LEVELS INCREASE ALONG THE FOOD CHAIN
- TRUE
- rESPIRATION
- Release ENGERGYY
- Heated Green houses are expensive to
- Heat up in the winters.
- Which part of a cell is ONLY for plants????
-
-CHLOROPLAST
-CELL WALL
-CYTOPLASM
