Grana
Chlorophyll

2

Photosynthesis process

Chlorophasts contains grana which contains chlorophyll and absorbs light energy to create glucose.

Or scientific equation
6Carbon Dioxide + water = 6glucose(c6h1206) + 6 oxygen + 6water

3

What light do plants absorb?

Any light on the visible light spectrum but preferably red and blue right and they reflect green light.

4

Producers / autotroph

At the base of the food chain and doesn't rely on other organisms for food. Plants use photosynthesis to create food.

5

Metabolism

Chemical equations that occur when an organism uses energy to grow and repair cells

6

Cellular Respiraiton

When oxygen is used to move glucose and atp around the organism

7

Aerobic respiration

The chemical breakdown of food saving oxygen. The reactions need enzymes, occurs in all body cells and releases energy.

8

Glycolysis

Process by which glucose is converted into a simple form, during which energy is released.

9

Cytosol

The fluid found inside cells.

10

Kerbs cycle

Part of the aerobic respiration process in which carbon dioxide and ATP are produced.

11

Electron transport : chain reaction

Part of the aerobic respiration process.

12

Mitochondria

Small rod shaped organelles that supply energy to other parts of the cell. They are usually too small to be seen with light microscopes. Singular form is mitochondrion.

13

Anaerobic respiration

The chemical breakdown of food without oxygen. The reaction needs enzymes, occurs in cells and realises less energy than aerobic respiration.

14

Lactic acid

The product of anaerobic respiration in animals also known as lactate.

15

Ethanol

An end prodyct of anaerobic respiration in plants, a form of alcohol

16

Obligate anaerobes

Organisms that can respire only anaerobically, when there is oxygen.

17

Species

A group of living organisms capable of interbreeding with each other but not with members of other species.

18

Population

A group of individuals of the same species living in the same area at a particular time

19

Community

More than one populations living in the same area at a particular time

20

Ecosystem

Communities of organisms that interact with each other and their environment

21

Producers

Organism at the base of the food chain that does not need to feed on other organisms; also known as an autotroph.

22

Decomposers

Organisms that breaks down organic matter into inorganic materials

23

Heterotrophs

Consumer

24

Herbivore

Animal that eats plants only

25

Primary consumers

The first consumer in a food chain; aka first-order consumer.

26

Detritivores

Animals that feeds on and breaks down dead plant or animal matter.

27

Ecological niche

The position of a species or population in its ecosystem in relation to each other.

28

Competition

The struggle among organisms for food, territory and other factors.

29

Parasitism

Mutualism

Commensalism

Where a parasite lives in/on the host and the parasite has the benefits but the host is affected negatively.

Relationship between two different organisms in which both benefit

Relationship between organisms where one benefits and the other is unaffected

30

Interspecific competition

Intraspecific completion

Competition between organisms of same species

Same as above but different species

31

Symbiotic relationship

Very close relationship between two organisms of different species. It may benefit or harm one of the partners.

32

Carrying Capacity

The maximum amount of an organism's population in an ecosystem

33

(X)iticdes

Something that kills (x)

34

Bioaccumulation

Magnification of concentrations of a substance such as a nonbiodegradable pesticide along the food chain; also known as biological magnification
