Section 2

Question 1

prokayutes

Answer 1

which include only bacteria, and
Cyanobacteria They lack membrane bound nuelei and mist of the organelles found in other cells.

Question 2

Eukaryotes

Answer 2

Which include the protists, tungi, Pants and animals, These are cells specialized to perform particular functions

Question 3

Cell wall

Answer 3

Present in eukaryotic Plant cells and bacteria prokaryles Main tuneron is to Suppet and Protect Channels in the cell wall
Connect neighbor calls(rigid membrane, found in plants and some bacteria)

Question 4

Ribosomes

Answer 4

Small dark dots found in the cytoplasm at the cen. responsible for protein Synthesis.(protein synthesis.)

Question 5

Endoplastic reticulum (ER)

Answer 5

forms a system
a tubular Channels
that brances thrughot
the Cytoplasm.(transport nutrients within the cell)

Question 6

mitochondria

Answer 6

sites of cellular respiration ,use glucose
to produce energy in form of ATP(breaks down glucose into ATP energy)

Question 7

Chloroplasts

Answer 7

found and in plants cells only site of photosynthesis in eukaryote plants(glucose and oxygen from carbon dioxide and water) gives plants to green colour

Question 8

vacuole

Answer 8

A large membrane enclosed Sac that
transport materials
thought the cell(storage)

Question 9

vesicle

Answer 9

Small vocuole, transport material
around the cell

Question 10

golgi Apparatus

Answer 10

stacks of membranes. functions in modifying packaging, String and distributing Preteins plodued by the ER Creates Small membrane Contained Sacs Called Vesicles(package proteins made you exocytosis)

Question 11

LySosomes

Answer 11

in animal celles ony, hold digestive enzymes, break down large molecules and old cell parts within the cytoplasm.(breaks down the nutrients and waste)

Question 12

Cell membrane

Answer 12

flexible Structure that Surrounds the cell, holding it togeter. regulates the passage at materials into and out of the cell Composed of a phodhoipid bilayer arranged with their hydrophobic fatty tails(flexible membrane around the eukaryotic)

Question 13

Passive Transport

Answer 13

movement of high to low Concentrations (down Conc gradient) which requiem the energy usage since molecules energy drives the movement

Question 14

Facilitated Diffusion

Answer 14

Specialized structres in the membrare allow larger water-solute molecules to diffuse. This is driven by the concentration gradient

Question 15

Osmosis

Answer 15

Diffusion of water across a semi permeable membrane

Question 16

Active transport

Answer 16

Movement of a substance from a area of low concentration area of high concentration

Question 17

function of proteins

Answer 17

Transport channels, enzyme, receptors, identification, communication

Question 18

lipids tails are…..

Answer 18

hydrophobic

Question 19

recognition proteins

Answer 19

-are embedded in the membrane but stick out into Surroundings So that cells Can recognize each other
ex-egg and Sperm cells link, , white blood cells recognizns and  attaching to bacteria, viruses

Question 20

Semi permeable membrane

Answer 20

A type of membrane which allows certain particles to pass through while others are excluded, can natural or synthetically  produce

Question 21

Hypotonic solution(osmosis)

Answer 21

describe the solution that has lower solute concentration than other  solution

Question 22

hypertonic solution (osmosis)

Answer 22

describe a solution that has a higher solute concentration to another solution

Question 23

isotonic solution(osmosis)

Answer 23

Describes a solution that has the same salute concentration as an another solution

Question 24

centrosome

Answer 24

Has a role in mitosis to separate chromosomes

Question 25

nucleus

Answer 25

contains DNA that genetic materials and directs all cellular activity(contains DNA)

Question 26

cytoplasm

Answer 26

Joe likes something that holds organelles contains nutrients for life process, found outside the nucleus and inside the membrane.

Question 27

nucleolus

Answer 27

located within the nucleus, responsible for creating ribosomes(humans only have in their cells)
