cell

Question 1

mitochondria

Answer 1

• powerhouse/energy production for cell

- food enters the cell as glucose and this is where glucose is converted into energy to power

Question 2

endoplasmic reticulum

Answer 2

• divides the cell into compartments
• forms surfaces where many chemical reactions occur
• two types, smooth, and rough

Question 3

cell membrane

Answer 3

select what goes in and out

Question 4

peroxisome

Answer 4

releases enzymes to breakdown harmful substances

Question 5

vacuole

Answer 5

stores everything

ex, fluid, waste, food, proteins, toxins etc (grandmas attic)

Question 6

lysosome

Answer 6

relates enzymes to digest old/worn out cells

Question 7

Golgi app/complex

Answer 7

modify and transport proteins

Question 8

microvilli

Answer 8

• not on all cells
• increases surface area for secretion or absorption
• short extension of the cell membrane

Question 9

centrioles

Answer 9

-aids in cell division by pulling the chromosomes towards the opposite poles to help in the formation of two new cells

Question 10

cytoplasm

Answer 10

fluid in cell

-found btw the nuclear membrane and cell membrane

Question 11

nuclear membrane

Answer 11

select what goes in and out of the nucleus

Question 12

nucleus

Answer 12

control centre

• contains all the genetic material and chromosomes
• regulates the passage of substances into the cell

Question 13

nucleolus

Answer 13

makes ribosomes

Question 14

what is the study of cells called

Answer 14

cytology

Question 15

cell functions

Answer 15

• obtain or make food
• digest and assimilate nutrients
• expel waste into the environment

Question 16

flagellum

Answer 16

• long, whip-like projection from the cell
• moves the cell
• in humans, the only cell with a flagellum is a sperm cell

Question 17

microtubules

Answer 17

-play an important role in lining up duplicated chromosomes and movement of chromosomes to opposite poles of a cell undergoing cell division (mitosis)

Question 18

rough end. reticulum

Answer 18

• gives a large surface area for ribosomes to attach to the cytoplasmic surface of the ER
• bumpy appearance
• allows for transportation of proteins into the ER

Question 19

smooth end. reticulum

Answer 19

-area of the ER without attachment of ribosomes

Question 20

ribosomes

Answer 20

makes protein

Question 21

cilia

Answer 21

hair like projections to filter

Question 22

vesicle

Answer 22

stores materials to transport

Question 23

chromatin

Answer 23
