A | B |
spontaneous generation | the belief that something non-living could turn into something living... MAGICAL! |
controlled variables | the variables that need to stay the same |
manipulated veriable | the variable that you change in order to measure something |
responding variable | the variable that you measure |
nucleus | the control center of the cell |
organelles | the components of the cell |
rough endoplasmic reticulum | has ribosomes on it and it transports stuff |
smooth endoplasmic reticulum | does not have ribosomes on it and it transports stuff |
golgi apparatus | looks like intestines and packages waste and proteins |
lisosomes | like the "hospital" of the cell |
cytoplasm | the gel-like substance that all of the organelles "float" in |
cell wall | provides structure for the plant |
cell membrane | controls the movement of water, nutrients, etc in and out of the cell |
vacuole | stores water and waste |
chloroplast | where photosynthesis takes place |
chlorophyll | is found inside chloroplasts |
cohesion | water molecules are attracted to one another |
adhesion | water "sticks" to the insides of the xylem tubes |
transpiration pull | water leaves the leaves (ha!) through transpiration. Water naturally wants to fill those empty spaces with more water. |
mitochondrion | where energy is made/the site of cellular respiration |
carbon dioxide + water = oxygen + glucose | photosynthesis |
oxygen + glucose = water + carbon dioxide | cellular respiration |
xylem | moves water and minerals from the roots to the leaves |
phloem | living cells transport sugars, starches and other food down to the stem and leaves |
endocytosis | when molecules outside of the cell are absorbed into the cell |
exocytosis | when molecules are in the cell and then transported outside of the cell |
hypertonic | when their is a higher concentration outside of the cell |
hypotonic | when their is a higher concentration inside the cell |
isotonic | when the concentrations inside and outside of the cell are equal |
osmosis | diffusion of water across a membrane |
diffusion | when molecules move from an area of high concentration to low concentration |
cuticle | waxy substance that protects the plant |
dermal tissue/epidermis | the outer layer of cells on a plant (for example, the bark on a tree) |
desalination | removing salt from sea water |
reverse osmosis | requires water to be pumped against its concentration gradient |
peritoneal dialysis | a type of dialysis that uses a catheter tube and allows the person to function whilst it happens |
hemodialysis | blood is removed completely from the body, cleaned by a machine and then returned to the body. More complicated. |
organs | a group of tissues that work together to perform a specific function |
tissues | a group of similar cells that perform a specific function |
systems | a set of interconnected parts. It can be open, closed or isolated. |
ground tissue | parts of the plant body not included in the dermal or vacular tissue systems; function in storage, photosynthesis and support |
vascular tissue | transport tissue formed in cells joined into tubes that carry water and nutrients through the body of the plant |
meristem | growth region of the plant with tissue in which cells divide by mitosis |
pallisade tissue cell | column-shaped mesophyll cells in a plant leaf; responsible for photosynthesis |
transpiration | loss of water from leaves (stomata) through evaporation |
guard cell | specialized epidermal cell that swells and contracts to control gas exchange through a stoma in a leaf |
turgor pressure | pressure exerted against a cell wall by the water that has entered the cell through osmosis |
root pressure | upward force exerted on water in the xylem in the roots of some plants |
lenticel | a raised spongy region in the stem of a woody plant that allows gas exchange between the atmosphere and the interior of a plant |
surface area to volume ratio | 6 divided by the side length = ? |
auxin | the type of plant hormone that promoes cell growth |
phospholipid bilayer fluid mosaic model | the idea that there are two layers of lipids in the cell membrane and materials can pass through it because there are fluids |
