Quizzmiss Day 2- Cell Strucure and Transport, organells, and photosynthesis

Mrs. Smith Honors Biology

the - is the basic unit of life

cell

-are made of RNA and are the site of protein assembly

ribosomes

the - is a membrane bound organelle containing the gentic information

nucleus

the - - contains smooth and rough and is the site where lipid membance parts are made

endoplasmic reticulum

- are cells that contain a true nucleus

eurkaryote

the - - modifies, packages and ships products from the ER

golgi apparatus

— are cells (organisms) that do not contain a nucleus

prokaryote

specialized membrane bound structures in the eukaryotic cell that carry out specific functions are called

organelle

a sac like organelle used for storage in plants can best be describes as a

vacuole

the - is a specialized fluid medium outside the nucleus where the organelles are found

cytoplasm

the - is an organelle found in plants and is the site of photosynthesis

chloroplast

the — is a membrane structure that surrounds the nucleus

nuclear envelope

the eukaryotic cell maintains shape with a supporting structure called the

cytoskeleton

— is the threadlike genetic material wound around protiens

chromatin

— are found in animal cells and aid in organizing cell divison

centriole

— are the condensed form of chromatin (X-like structures)

chromosome

the — is responsible for converting chemical energy found in foods to a usable source (ATP)

mitchondria

the — is a small condensed portion of the nucleus containing RNA for the assembly of ribosomes

nucleolus

the work of many scientists went into the formulation of the - - which states that all livng things are made of cells that came from living organisms.

cell theory

the — are located in the chloroplasts annd are the site of the light reaction in photosynthesis

thylakoid

— are organisms that must consume orgainic molecules in order to produce energy

heterotroph

— is an enzyme that creates ATP in the inner thylakoid membrane

ATP synthase

the light dependent reaction begins in photosystem

PII

— is the process where plants harvest the sun’s energy and place it into a glucose molecule

photosynthesis

— is the electorn carrier that is used in PSI to transfer energy to the Calvin Cycle

NADPH

— is the primary pigment that plants use to absorb light energy

chlorophyll

the — is where the Calvin Cycle takes place

stroma

— is a molecule produced in both autotrophs and heterotrophs that contains stored potential energy

ATP

an — is an organism that produces its own energy

autotroph

the — connects PSII to PSI

ETC

a — is a molecule that absorbs light at a particular frequency while reflecting all others

pigment

Chlorophyll-a absorbs - and - light best while reflecting predominantly - light

red, violet, green

in PSII - is split to form -, - and 2e-

water, H+, o2

the - - reaction consists of PSI and PSII

light dependent

the - - is where CO2 is fixed into the growing carbohydrate

calvin cycle

a - is an organism that produces its energy using energy from the sun to fix CO2 into usable sugars

photoautotroph

a - is a stack of thylakoids

granum

one of most important functions of cell membrane

regulate movement of molecules into and out of the celll

passive transport

no energy required because movement occurs down the concentration gradient

diffusion

Movement of molecules from an area of greater concentration to an area of lesser concentration

osmosis

Diffusion (movement) of water across a

selectively permeable membrane

facilitated diffusion

involves the use of protein channels located in the cell membrane

If a cell is placed in freshwater, which way will the water move

INTO THE CELL!! Which will cause the cell to swell and burst

blood is what with cells

isotonic

isotonic

the concentration of solutes is the same inside and outside of the cell

If you drink seawater, what will happen to the water

It will be pulled OUT OF your cells

the concentration of solutes is the greater outside of the cell

Hypertonic

active transport

requires energy because material is moved across the membrane  going against the concentration gradient

why do we need active transport

Transport (or pump) macromolecules across the cell membrane

Endocytosis

taking materials into a cell (forms a vacuole within the cytoplasm

what is 1

nucleolus

what is 2

nucleus

what is 3 / the dots

ribosome

what is 4/ helps transport substances

vesical

what is 5

rough er

what is 6

golgi apparatus

what is 7 / structural element

cytoskeleton

what is 8

smooth er

what is 9

mitochondria

what is 11

cytoplasm

what is 13

centriole

detoxification organelle

smooth er
