What are pooters used for?
Pooters are for collecting ground insects.
1 of 16
What are pitfall traps used for?
Used to investigate ground insects.
2 of 16
What are pond nets used for?
Used to collect aquatic animals in ponds and lakes.
3 of 16
What are Quadrats used for?
to study the distribution of small organisms.
4 of 16
What is the word equation for photosynthesis?
Carbon Dioxide + Water ---> Glucose + Oxygen
5 of 16
How are leaves adapted for efficient photosynthesis?
Leaves are broad-large surface area exposed to light. Leaves contain chlorophyll in chloroplasts to absorb light. Leaves are full of stomata-let C02 and 02 in and out and allow water vapour to excape-transpiration.
6 of 16
What is diffusion?
Its the movement of particles from an area of higher concentration to an area of lower concentration.
7 of 16
What is respiration?
Respiration is the process of breaking down glucose to release energy, which goes on in every living cell.
8 of 16
What is osmosis?
Its the movement of water molecules across a partially permeable membrane from an area of high concentration to an area of low concentration.
9 of 16
What is transpiration?
its the loss of water from the plant.
10 of 16
Whats the Xylem?
are tubes that transport water and minerals from the roots to the rest of the plant.
11 of 16
Whats the Phloem?
are tubes that transport sugars from the leaves to growing and storage tissues.
12 of 16
What is active transport?
uses energy from respiration to help the plant pull minerals into the the root hair against the concentration gradient.
13 of 16
Name the limiting factors for photosynthesis?
light intensity, carbon dioxide and temperature.
14 of 16
What is respiration used for?
the release of energy to: build up larger molecules, contract muscles, maintain a stable body temperature.
15 of 16
What is the equation for anaerobic respiration?
Glucosse ---> Lactic Acid (+ Energy)
