Flashcards in Unit 2: Cell History & Organelles Deck (29):
1

Type of cell that has a nucleus and other membrane-bound organelles

eukaryotic cells

2

Makes proteins for the membrane or for export to other cells

Rough ER

3

Two types of electron microscopes

Scanning

and 

Transmission 

Electron Microscopes

4

Type of cell that bacteria are classified as

prokaryotic cell

5

Organelles only found in plant cells

Chloroplasts

Central Vacuole

Cell Wall

6

Microscope that gives us an internal up-close view of a speciman

Transmission Electron Microscope

7

Component of cell walls

Cellulose

8

Contains the genetic material of the cell in eukaryotic cells

nucleus

9

During cellular respiration, this organelle breaks down large carbohydrate molecules into individual glucose molecules.

Lysosome

10

Helps to move around organelles inside the cell as well as products from the ER's to the Golgi bodies.

Cytoskeleton

11

Concluded that all animals are made up of cells

Theodore Schwann

(Schwann=swan=animal)

 

12

Receives the products of the ER's and ships them to the membrane for export.

Golgi apparatus

13

Came up with the word cell

Robert Hooke

14

Organisms that are only one cell in size are known as....

unicellular

15

Organism this is made up of more than one cell is called?

multicellular

16

Found inside of the nucleus.  They synthesize (make) the ribosomes

nucleolus

17

Makes phospholipids (fats) for the cell membrane

smooth ER

18

Type of microscope that gives us an external 3D view of a specimen

Scanning electron microsope

19

Type of microscope that can view a living organism

Light microscope

20

Concluded that all cells come from preexisting cells

Rudolf Virchow

21

Helps make the cells mobile

cilia and flagella

22

Organelles only in animal cells

Lysosomes

Cilia and Flagella

 

23

Microscope that coats the speciman with a metal.  Electrons bounce off the speciman and produce a surface image

Scanning electron microscope

24

Regulates the movement of food into the cell and waste out of the cell

Cell membrane

25

Concluded that all plants are made up of cells

Matthias Schleiden

26

Microscope that thinnly slices the speciman.  Electrons are then forced through the speciman. The rate at which the electrons are collected on the other side is used to put together an image of the inside

Transmission electron microscope

27

Type of cell that lacks a nucleus

prokaryotic cell

28

First to look at protozoa (moving living organisms) in pond water

Anton Van Leewenhooke

29

Type of micoscope we use in the classroom

light microscope
