Flashcards in Cells Deck (27):
1

Function of cells

Perform chemical reactions to create life processes (metabolism)

2

Compartmentalization

When you have a single cell, they are individual

They do their own thing but have a little specialization

3

General cell structure

1.) plasma(cell) membrane: outside
2.) cytoplasm: between cell and outside
3.) nucleus: contains dna, codes for everything

4

Plasma (cell) membrane

Outside part is what makes the cell different from eachother

5

Cytoplasm

Jellylike fluid & organelles

6

Matrix

Increase surface area

7

Golgi complex

Organizes and packages & sends it off (diffusion)

8

Ribosomes

Where proteins made

9

Smooth ER

Storage

10

Vessicle

Big package

Moving/transport vessicle

11

Lysosome

Intracellular (inside cell) digestion

Breaks down infection with enzyme

12

Proteasome

Breaks down proteins

13

Light microscope

LM

Uses visible white light that passes through cell

14

Transmission electron microscope

TEM

uses beam of electrons that passes through cell

Sees the inside

15

Scanning electron microscope

Beam of electrons which is reflected off the surface of a cell to provide a 3d study of cell surface

Cant see inside, only outside

16

Cell biology/ cytology

Study of cells

17

Apoptosis

Normal cell death

Programmed

18

Necrosis

Abnormal cell death

Forms necrotic tissue

19

Neoplasia

Abnormal cell growth

Ex: cancer

Result: tumor

20

Hyperplasia/hypoplasia

Tissue of all similar cells

21

Hyperplasia

Cell growth to increase mass

22

Hypoplasia

Normal cell decrease

Atrophy

23

Metaplasia

Abnormal

Changing of one type of cell tissue to another

Ex: smoking

24

Hypertonia/ hypotonia

Cell

25

Hypertonia

Increasing cell size

Muscle and lipid cell

26

Hypotonia

decreasing cell size

Muscle and lipid cell

27

Cellular diversity

All cells have an optimal volume to surface area ratio

Difference in shape and concentration of cells based on particular function
