Q

WHAT IS a lysosome and it’s FUNCTION

A
  • the digestive system of the cell
  • digestive enzymes break down waste molecules
  • it helps with detoxification of the cell
  • without a membrane, it cant use the distructive enzyme

Q

What is centrioles of centrosome

A
  • a centriole is a small set of microtubes arranged in a specific way
17
Q

At what angle do teo centrioles meet

A

Right angle

18
Q

How many groups of microtubes are there

A

9

19
Q

What do centrioles do during cell division

A

They are found in pairs and move towards the 2 poles (opposite ends)

20
Q

What are threads and what do treads do during division

A

Threads= mitotic spindle
Groups attach to the centrioles
Its near the nucleus and not sean during division

21
Q

Do threads and centrioles work in mitosis or meiosis

A

Both

22
Q

What is the difference between the cilia and flagella in appearance

A
  • they are structurally identical
  • cilia = short and have large numbers per cell
  • flagella = longer and fewer numbers
23
Q

What are the functions of the flagella and cilia and the difference

A

They are organells of movement

  • flagella = wave like motions
  • ciliary movement = power stroke + recovery strokes
