What are the 3 basic parts of a cell

Cell membrane
Nucleus
Cytoplasm

1

What substance helps to maintain the inner cell membrane stable?

Cholesterol

2

What is mucus?

A fluid that lubricates the tissues in the mucous membrane and also help immune function by trapping foreign matter

3

What does the mucus membranes line ?

Tubular organs
Oral and nasal cavities
Respiratory tract
Urinary tract

4

What are the 4 types of transport ?

Diffusion
Osmosis
Facilitated diffusion
Active transport

5

What are the two types of endoplasmic reticulum

Smooth and rough

6

Rough endoplasmic reticulum is involved in what

The building of proteins

7

Smooth endoplasmic reticulum is involved in what

Building lipids (fats)

8

What does cytosol contain?

Water (mostly)
Glucose
Amino acids
Fatty acids
Ions
Lipids
Proteins
ATP
Waste products

9

Where is the site of many chemical reactions

In the cytosol

10

What is cytokinesis

The division of the cytoplasm of a cell

11

What are the 4 phases of mitosis

Prophase (two new centriole pairs move to opposite ends of the cell)

Metaphase (chromosomes align near the middle portion between the centrioles, and spindle fibers attach to them)

Anaphase (centromere secretions of each chromosomes, and move toward opposite ends of the cell)(cytokinesis begins here)

Telophase (chromosomes arrive at each pole, and new nuclear membranes form)

12

4 types of cells?

Epithelial tissue
Connective tissue
Muscle tissue
Nervous tissues

13

Example of epithelial tissues?

Body surfaces (skin)

Cover and lining internal organs (gallbladder)

Make up the glands (enabling secretion and absorption to occur throughout the body)

14

Name the 9 types of epithelial tissues

Simple squamous
Simple cuboidal
Simple columnar
