Newton's Second Law of motion
Acceleration of a mass is porportional to the net force applied to it.
Someone who tested spontaneous generation with jars of meat. Lead to the discovery of active principle.
First to describe single-cell organisms as he studied blood cells, pond water, and matter scraped from his teeth.
The two S
Discovered and created the cell theory. Studied plants and animal cells, noticing that they had nucleis.
Tested the two S's hypothesises and concluded that "Where a cell exists, there must have been a pre-existing cell".
All organisms are composed of one or more cells. Cells are the smallest funtion unit in life. All cells are produced from other cells.
_______________ need energy. Produce wastes. reproduce. grow. respond and adapt to environment.
Transmission Electron Microscope
Produces 2 dimensional images of a specimen using a beam of electrons.
Confocal Laser Scanning Microscope
Produces 2 and 3 dimensional images of a specimen using a laser that 'slices' the 3D specimen.
Scanning Tunnelling Microscope
Produces a 3 dimensional image of a specimen as a metal probe brought near a specimen, electrons flow onto the atoms of the specimen.
Rough Endoplasmic Reticulum
This cell structure builds proteins which are then packaged in vesicles for transport.
Smooth Endoplasmic Reticulum
Makes lipids and packages larger molecules (lipids and proteins) in vesicles. These packages are then transported to the golgi app.
Sorts and repackages the molecules which are then distributed to other parts of the cell.
Only plant cells have this as it is a bigger storage place for food, water and minerals in the cell.
Composed of phospholipids and proteins arranged in two layers called phospholipid bilayer.
Forms tunnel-like pores in the cell membrane allowing electrically charged ions in and out of the cells.
A type of passive transport describing the movement of particles from high to low concentration.
A form of diffusion involving the movement of water molecules from a high to low concentration.
Concentration gradient, temperature, and particle size contribute to factors of __________?
Type of active transport protein as it ______ ions in and out of the cell. (Potassium and Sodium ions)
This process is used by cells to take in substances, in which the membrane folds in, encloses the item in a sphere, then pinches off a vesicle.
A process that expells compounds into the external environment by fusing the membrane of a vesicle or vacuole with the cell membrane
Process used to filter out wastes in blood while keeping in the important components (blood cells, proteins etc). Involves a dialysis tubing.
Biochemical process powered by light energy in which carbon dioxide from the air and water from the soil are combined to make glucose and oxygen.
Upper and lower cells of a leaf that are tightly interlocked to prevent physical damage or penetration by pathogens. (disease)
Substance on the top layer of epiidermis that acts as a water barrier to conserve water.
One of the main types of photosynthesis cells of plants. Long and narrow that are closly packed together containing chloroplasts.
One of the main types of photosynthesis cells of plants that are located right beneath the upper epidermis.
Spongy Tissue cells
One of the main types of photosynthesis cells of plants that are lossely packed and contain few chloroplasts. These cells help the leaf exchange gases and water with the environment.
Spongy Tissue cells
One of the main types of photosynthesis cells of plants that helps the leaf exchange gases and water with the environment.
Both plants and animals consume oxygen and produce carbon dioxide and water during _________.
In transpiration, water moves into the guard cells by osmosis, and as it does so, the pressure inside the cells _______ and causes the cell to swell.
Transportation of materials within the body of plant involves two types of vascular tissue, ________ and _________. (water, sugars)
Type of vessel that transports water and inorganic minerals through the plant from the root to stem and leaves.
Living cells form ______ vessels with porus cell walls. Consists of sieve tubes and companion cells arranged from end to end.
_______ vessels transports organic food material (produced by leaves during photosynthesis) to all parts of the plant.
Type of diffusion used by transport proteins to aid the diffusion of particles across the membrane of a cell.
Root cells use facilitate diffusion and ______________ to move minerals across their membranes. (Uses ATP)
Concluded that the nucleus of an atom contained all positive charges and negative charges located great distances away.
Law of Conservation of mass
During a chemical reaction, the total mass of the reacting substances are always equal to the total mass of the resulting substances.
Energy is released/consumed, odour change, color change, irreversable, formation of a precipitate (somtimes) are all forms of what change?
