Q

Why does the volume to surface area ratio matter to cells?

A
  • The volume increases faster than the surface area.
  • If the volume gets too big, the surface area won’t be large enough and the cell won’t be able to expel enough waste or import enough nutrients

Q

Why are cells small?

A
  1. The ratio of volume to surface area limits how large the cell can be
  2. The nucleus can only control a certain amount of cytoplasm

16
Q

These types of cells are able to specialize

A

Eukaryote

17
Q

What is cell specialization?

A

The ability of eukaryotic cells to do one specific function (ex. heart cell, nerve cell, blood cell)

Shape is related to function

18
Q

What are the two main parts cells are divided into?

A

The nucleus and the cytoplasm

19
Q

The organelle responsible for containing the cell’s DNA

A

Nucleus

20
Q

Which organelle contains the instructions for making proteins?

A

The nucleus

The instructions are found in the DNA

21
Q

Surrounds the nucleus, lets things in and out

A

Nuclear membrane

22
Q

What is the function of the nucleolus?

A

The inner portion of the nucleus that is responsible for the production of ribosomes

23
Q

The jelly-like substance outside of the nucleus where most chemical reactions take place

A

Cytoplasm

24
Q

Which organelle functions like roadways in the cell by transporting materials?

A

Endoplasmic Reticulum

25
Q

Helps in making lipids

A

Endoplasmic Reticulum

26
Q

What is the function of the golgi apparatus?

A

Modifies, sorts, and packages proteins and other materials (UPS)

27
Q

Contains digestive enzymes

A

Lysosome

28
Q

What is the function of the lysosome?

A

Cleans up dead/excess materials (janitor)

29
Q

The powerhouse of the cell

A

Mitochondria

30
Q

Which organelle uses materials to make energy for the cell?

A

Mitochondria

31
Q

What is the function of the ribosome?

A

Makes proteins

32
Q

Stores water and other materials

A

Vacuole

33
Q

Do NOTHING except during ______

A

Centrioles; cell division

34
Q

Help maintain the shape of the cell

A

Cytoskeleton

35
Q

Flexible material that surrounds the cell, allows things in and out

A

Cell Membrane

36
Q

Rigid structure outside of the cell membrane; supplies structure and strength to the cell

A

Cell Wall

37
Q

Chloroplasts’ function are to

A

Use energy from the sun to do photosynthesis (make plant food)

38
Q

How are cilia different from flagella?

A

Cilia are hair-like structures that form around the outside of the entire cell

Flagella are whip-like (tails) and only a couple of them can be found on the outside of some cells

Both are organelles for cell movement

39
Q

Why are cells small?

A
  1. They’re limited by the ratio of surface area to volume

(volume increases faster than surface area)

  1. The nucleus can only control a certain amount of active, living cytoplasm
