Q

What are the three main things to Cell Theory?

A
  1. All living things are made of cells
  2. Cells are the basic unit of life
  3. Cells come from the reproduction of existing

Q

What is the difference between Eukaryote and Prokaryote cells?

A

Eukaryotes: Have cells that have a nucleus and membrane-bound organelles
Prokaryotes: cells have no nucleus/organelles and are very simple

16
Q

Where and what is ribosomes?

A

Can be on rough ER or free-floating

16
Q

what is the function of the mitochondria?

A

Makes energy called ATP, Has its own DNA

17
Q

What is the function of ribosomes?

A

Join amino acids to make proteins

18
Q

What and where is endoplasmic reticulum?

A

Smooth and Rough (rough has ribosomes on it)

19
Q

What is the function of ER?

A

Creates cell products and transports things

20
Q

What is Golgi Bodies?

A

Stacks of flattened sacs

21
Q

What is Golgi Bodies’s functions?

A

Receives proteins from ER, Modify, sort, and package things for storage or transport out
of cell

22
Q

What are lysosomes?

A

Contain digestive enzymes

23
Q

What is the function of lysosomes?

A

Break down food, bacteria, cell parts for the cell

24
What is the vacuole?
fluid-filled sacs
25
What is the function of vacuole?
storage of sugars, proteins, wastes, water,etc
26
What and where are chloroplasts?
Found in plant producers (not found in animal cells) VERY GREEN
27
What is the function of chloroplasts?
Use energy from sun to make their own food (glucose). Energy from sun is stored in chemical bonds of sugars
28
What and where is centrosomes?
Complex of centrioles (microtubules) and protein structures and Composed of microtubules
29
What is the function of centrosomes?
Centrioles can only be seen during cell division aid in moving chromosomes around during cell division
30
What is found in plant cells only?
Cell Wall and Chloroplast
31
What is found in animal cells only?
centrioles
