Answer 16

chloroplasts

Question 17

What do euglena lose in direct sunlight?

Answer 17

chloroplasts

Question 18

Eukaryotes

Answer 18

cells that have a nucleus (both animal and plant)

Question 19

Prokaryotes

Answer 19

cells that do not have a nucleus (Eubacteria and Archaebacteria)

does not have organelles

Question 20

Why are eukaryotic cells larger than prokaryotic cells

Answer 20

their internal membrane system allows compartmentalization of fxns which makes them have a larger surface area for nutrient exchange and placement of enzymes

Question 21

Nucleus

Answer 21

control center of the cell

protects DNA/RNA

Question 22

Nuclear Pore

Answer 22

holes in the nuclear envelope that allow materials to pass in and out the nucleus

Question 23

Nuclear Envelope

Answer 23

outer membrane of the nucleus

Question 24

Nucleolus

Answer 24

found inside the nucleus

responsible for rRNA synthesis

Question 25

Chromatin

Answer 25

loose DNA to make chromosomes within the nucleus

Question 26

Golgi Sacks

Answer 26

receives vesicles from ER modifies proteins and lipids makes lysosomes process molecules and packages for secretion

Question 27

Rough ER

Answer 27

covered in ribosomes protein synthesis they produce, fold, control quality, and despatch proteins

Question 28

Smooth ER

Answer 28

lipid, steroid, carb synthesis stores calcium important for liver function: helps detoxify

Question 29

Mitochondria

Answer 29

has two membrane (bilayer) has own circular DNA, ribosomes, and proteins site of ATP production

Question 30

Lysosomes

Answer 30

membrane enclosed vesicles that contain inactive digestive enzymes and when activated(pH drop btw 2-4) they break down certain materials in the cell cell clean up made by the Golgi Body

Question 31

Cytoskeleton

Answer 31

network of fibers in cytoplasm that hold cell together Microfilaments Microtubules Intermediate Filaments

Question 32

Microfilaments (Actin Filaments)

Answer 32

thin filaments in cytoplasm that change shape have a short life span

Question 33

Microtubules

Answer 33

spiral strands of protein molecules that form tubelike structures

Question 34

Intermediate Filaments

Answer 34

protein rods that provide mechanical support for the plasma membrane where it comes into contact with other cells

Question 35

Centrosomes

Answer 35

aids in cell division they are 90 degrees to each other and they are formed by 9 sets of triplets of microtubules

Question 36

Peroxisomes

Answer 36

detoxifies harmful substances in the cell protects cell from oxidative environment eliminates anything that "attacks" your cells saves you from producing too much oxygen

Question 37

Cytoplasm

Answer 37

jellylike fluid inside the cell where organelles are suspended

Question 38

Ribosomes

Answer 38

consists of RNA they bind mRNA and tRNA to synthesize proteins has a large and small subunit that come together to capture the mRNA then break apart when synthesis is done

Question 39

Cilia

Answer 39

hairlike projections that extend from the plasma membrane

Question 40

Flagella

Answer 40

long whiplike structure that helps a cell move made up of microtubules

Question 41

Secretory Vesicles

Answer 41

mediates transport from an organelle to specific sites at the cell membrane move molecules inside the cell (exocytosis)

Question 42

Vacuoles

Answer 42

membrane enclosed structure holds pressure (water regulation) stores food, water, waste and other materials Turgidity-it is swollen Tonoplasts-pressure of water pushing against each other to give its structure larger in plant cells

Question 43

Plasmodesmata

Answer 43

how plant cells communicate they channel btwn adjacent plant cells

Question 44

Chloroplast

Answer 44

found in plant cell capture the energy from sunlight and converts it into chemical energy double membrane
