eukaryotic

Question 1

what is the definition of a nucleus?

Answer 1

a membrane bound organelle that contains chromatin and nucleous

Question 2

In eukaryotic cells what does DNA associate with to form a complex called chromatin?

Answer 2

histones (proteins) to form a complex called chromatn

Question 3

what does the nucleolus produce and what does Dna contain to help with this?

Answer 3

RRNA and Ribosomes for photosynthesis. Dna contains info to rpoduce MRNA and TRNA

Question 4

Describe what the mitochondria does?

Answer 4

the mitochondria is the site of aerobic respiration

Question 5

what does the inner membrane of the mitochondria do to increase surface area?

Answer 5

folds into cristae to increase the surface area for enzymes involved

Question 6

what’s the purpose of the cel wall?

Answer 6

provides structure on outer layer of cell for support and structure

Question 7

what does the cell wall contain?

Answer 7

cellulose (in plants and algae) chitin (in fungi) Murein (in prokaryotes)

Question 8

what is a vacuole?

Answer 8

a membrane bound organelle with the cell sap

Question 9

what role does the vacuoe have?

Answer 9

keeps (plant) cells turgid (swollen by fluid)

Question 10

what is the tonoplast?

Answer 10

membrane of the vacuole that keeps the vacoule acidic by bringing protons

Question 11

what is the cell membrane?

Answer 11

a phospho lipid bilayer that regukates transport in and out the cell

Question 12

what does the cell membrane have to achieve it’s function?

Answer 12

contains protein and cholesterol

Question 13

what is the function of ribosomes?

Answer 13

synthesize ,store and transpot lipids and carbohydrates and the site of translation during protein synthesis

Question 14

what do ribosomes have to transport proteins and material throughout the cell?

Answer 14

fluid-filled tubules

Question 15

what type of structure does a ribosomehave to increase surface area?

Answer 15

fold structure - large surface area for protein synthesis

Question 16

Difference between rough and smooth endoplasmic reticulum?

Answer 16

one has ribosomes surrounding it while the other lacks it but both perform the function of synthesizing, storing and transporting lipids

Question 17

where are 70s and 80s proteins found?

Answer 17

found in prokaryotic and eukaryotic cells and are subunits made of RRNA and protein

Question 18

what are the function of chloroplasts?

Answer 18

double membrane organelle which is the site of aerobic respiration

Question 19

what does the thylakoid do in chloroplasts?

Answer 19

absorbs sunlight for photosynthesis tto occur and stacks up to form gana toincrease surface pigments to absorb light

Question 20

what does the stroma do in the chloroplast?

Answer 20

provides nutrients to the tissue or organ and removes waste and extra fluid

Question 21

what does the granum do in the chloroplasts?

Answer 21

increases surface area of thylakoids which results in more light being absorbed in photosynthesis

Question 22

what do the membranes of thylakoids have?

Answer 22

contain pigments involved in photosynthesis

Question 23

what is the golgi vesicle ?

Answer 23

plays a role in digestion and immune response. lysosomes are a type of them which contains lyzozyme enzymes.

Question 24

what is the golgi apparatus?

Answer 24

responsible for modifying proteins and packaging them into vesicles
