Eukaryoric Cells and Organelles

Question 1

function of cell-surface membrane

Answer 1

regulate the movement of substances in and out the cell, also have receptors which allow them to respond to chemicals like hormones

Question 2

aspects of the nucleus

Answer 2

nuclear envelope, chromatin, nucleolus and nuclear pore

Question 3

function of the nucleus

Answer 3

controls cell activity
contains genetic material
DNA contains instructions to make proteins
Pores allow substances to move between the nucleus and the cytoplasm
Nucleolus makes ribosomes

Question 4

function of mitochondria

Answer 4

Site of aerobic respiration which produces ATP. Mitochondria are found in a large number of cells that are very active and require a lot of energy

Question 5

function of chloroplast

Answer 5

Site of photosynthesis

Question 6

golgi apparatus

Answer 6

it processes and packages new lipids and proteins. Also makes lysosomes

Question 7

golgi vesicles

Answer 7

stores lipids and proteins made by the golgi apparatus and transports them out of the cell

Question 8

function of lysosomes

Answer 8

contains digestive enzymes called lysozymes, kept away from cytoplasm surrounded by a membrane. can be used to digest invading cells or break down worn out components of the cell

Question 9

function of ribosomes

Answer 9

the site where proteins are made

Question 10

function of rough endoplasmic reticulum (RER)

Answer 10

folds and processes proteins that have been made at the ribosomes

Question 11

function of smooth endoplasmic reticulum (SER)

Answer 11

synthesis and processes lipids

Question 12

function of the cell wall

Answer 12

function of the cell wall supports cell and prevents them from changing shape

Question 13

function of the cell vacuole

Answer 13

helps to maintain pressure inside the cell and keep the cell rigid. This stops plants from wilting. Also involves isolating unwanted chemicals inside the cell
