Cell Wall
Only in plants. Holds in fixed position; stops too much water consumption and from bursting.
1 of 40
Cell Membrane
All cells have this. It controls movement of substances in and out of the cell.
2 of 40
Cytoplasm
Jelly-like substance which holds the organelles. Also a transport system called cytoplasmic streaming.
3 of 40
Nucleus
Control center of cell with chromosomes inside which make DNA which carry info about proteins.
4 of 40
Nucleolus
Darkened part of nucleus. Contains genetic info for production of ribosomes.
5 of 40
Chloroplasts
Responsible for process of photosynthesis
6 of 40
Vacuole
Fluid filled storage spaces (sacks). Plants have large ones full of cell sap. Contains water, salts, sugars, acids and chemicals.
7 of 40
Mitochondrion
Power house of cells. Respiration occurs here.
8 of 40
Lysosome
Stores digestive enzymes that break down old organelles and some complex molecules.
9 of 40
Ribosome
Responsible for protein synthesis. Often found on the ER
10 of 40
Endoplasmic Reticulum
Transport system for proteins throughout cell. Smooth ER transports lipids, rough transports proteins.
11 of 40
Golgi Body
Sorts and packages protein for secretion. Create lysosomes and transport lipids.
12 of 40
Cell Theory
All living things are made up of cells. Cells are the smallest living units of life. All cells come from pre-existing cells.

Robert Hooke
First person to use the term 'cell' when describing cork.
14 of 40
Robert Brown
Discovered the nucleus of plants.
15 of 40
Chemicals in cells
Nucleic acid, proteins, carbohydrates, lipids, water, sodium chloride, carbon dioxide and oxygen.
16 of 40
Human Impacts
Land clearance, slash and burn agriculture, integrated pest management, land and water degradation, erosion, soil acidification, soil and water salinity, polluting the atmosphere and introduced species.
17 of 40
Allelopathy
Chemicals are released into the soil by plants to influence another. Example: Pine tree's needles drop to the ground and decompose, releasing chemicals which stop plants growing too close.
18 of 40
Parasitism
Parasite feels on hots's tissue. Example: Tape worm in human.
19 of 40
Mutualism
Two species have some benefit from living together. Example: Clown fish and sea anemone.
20 of 40
Commensalism
One is benefited and another is unharmed. Example: Fig growing up another trees trunk to get closer to the sun.
21 of 40
Food Chain
Shows the movement of energy from one living thing to another.
22 of 40
Food Web
Shows the complex food interaction within an ecosystem.
23 of 40
Trophic Levels
producer --> herbivore --> carnvivore
24 of 40
Reliability
The degree to which an assessment tool produces stable and consistent results. Improvement: do more tests are average it out.
25 of 40
Validity
Refers to how well a test measures what it is purported to measure. Improvements: make sure it is a fair test. FORMULA ... ICDRC
26 of 40
Fluid Mosaic Model
Current model of the cell membrane. Made of a double layer of phospholipids, which have hydrophobic tails and hydrophilic heads.
27 of 40
Surface Area To Volume Ratio
Cells have a large SA:V. The larger the SA:V, the GREATER the rate of movement of substances into and out of the cell.
28 of 40
Diffusion
The movement of any molecules from a region of high concentration to low concentration until equilibrium is reached.
29 of 40
Osmosis
The movement of WATER molecules from a region of high concentration to low concentration through a selectively permeable membrane.
30 of 40
Light Microscope
Cheaper, observe living tissue, only see basic organelles in less detail.
31 of 40
Electron Microscope
More expensive, only observe dead tissue, high magnification and resolution.
32 of 40
Photosynthesis
Carbon Dioxide + Water --> Glucose + Oxygen ....... 6CO2 + 6H2O --> C6H12O6 + 6O2
33 of 40
Respiration
Glucose + Oxygen --> Carbon Dioxide + Water + Energy (ATP) ....... C6H12O6 + 6O2 --> 6CO2 + 6H2O + Energy
34 of 40
Sampling Methods
Random quadrats, transects and mark-release-recapture (CxR/MR)
35 of 40
Test for Glucose
Benedict's solution
36 of 40
Test for Starch
Iodi
