1

Rough Endoplasmic Reticulum is responsible for

Protein assembly, secretory granules, ribosomes

2

Ribosomes stain

dark

3

Golgi Apparatus

packages molecules to vesicles

4

Basal bodies

formed from centrioles with cylindrical microtubules

5

Peroxisomes

break down long chain FAs and H2O2

6

What are microfilaments made of?

Actin

7

What are microtubules made of?

Tubulin

8

What do chief cells release?

Pepsinogen

9

What do parietal cells release?

Gastric acid to change pepsinogen to pepsin

10

What color do parietal cells stain?

Pink with a dark nucleus (fried egg)

11

What color do chief cells stain?

Dark and located next to parietal cells

12

Are pale staining nuclei more or less active than dark staining nuclei?

More active

13

What organelle stains pink?

Mitochondria

14

What effect does mucus have on the nucleus?

It displaces the nucleus to the edge of the cell and creates a pyramidal cell

15

What is a defining characteristic of the plasma cell?

The golgi apparatus does not stain and contrasts the nucleus

16

Why do plasma cells stain blue?

The production of antibodies by ribosomes

17

Polymorphonucleur cell

Neutrophil

18

What type of microfilaments are in microvilli

Actin filaments

19

How do you determine microvilli under a microscope

It is a shiny brush border

20

What are cilia made of?

Tublin, microtubules

21

What surface modification is a basal body?

CIlia

22

Which is a more active nucleus? Round or elongated?

Round

23

If a nucleus stains dark, what is it composed of?

Heterochromatic (compressed DNA)

24

What color does euchromatic nuclei stain?

Lighter than heterochromatic

25

What are cell inclusions?

Temporary structures that accumulate inside the cell

26

Name types of cell inclusions

Lipids, crystals, pigment

27

What causes vacuoles in stains?

Lipids and glycogen don't stain and leave empty spaces

28

What color does melanin stain?

Brown

29

Describe prophase

DNA is jumbled and not separaed

30

Describe Metaphase

Chromosome are lined along the center
