Flashcards in Bio Cell Parts Deck (45):
1

biology

scientific study of life

2

evolution

process of change that ahs transformed life on earth

3

What are the properties of life?

order regulation, reproduction, energy processing, growth and development, evolutionary adaption, response to environment

4

emergent properties

science becomes more advance, we know more

5

negative feedback

produces product to stop something

6

positive feedback

stimulus for something to go

7

What are the three domains?

bacteria, archaea, eukarya

8

What are the four kingdoms?

protists (mostly in pond water)
fungi (mushrooms)
plantae (plants)
animalia (animals)

9

theory

idea supported by experimentation

10

chemistry

study of matter

11

compounds

two or more elements

12

energy

capacity to do work

13

potential energy

energy that has the ability to do work

14

kinetic energy

energy in motion

15

valence electrons

outermost electron shell

16

covalent bonds

sharing of a pair of valence electrons by 2 atoms

17

nonpolar covalent bond

electrons are shared equally

18

electronegativity

attraction of a particular kind of atoms for the electrons of a covalent bond

19

organelles

membrane enclosed compartments

20

cell fractionation

takes cell apart and separates the major organelles and other subcellular structures from one another

21

cytosol

semifluid, jellylike. allows for flexibility

22

eukaryotic cell

an organelle called nucleus bound by double membrane

23

cytoplasm

jelly-like substance. shock absorbent. keeps everything in its place

24

nuclear envelope

double membrane

25

ribosomes

complexes made of ribosomal RNA and proteins, cellular components tat carry out protein synthesis

26

free ribosomes

suspended in the cytosol

27

bound ribosomes

outside of endoplasmic reticulum or nuclear envelope

28

vesicles

sacs that transport things around

29

smooth ER

metabolic process; synthesis of lipids, metabolism of carbs, detoxification of drugs and poison

30

rough ER

check protein for errors, destroys bad proteins

31

Golgi apparatus

process, package, and ship transport vesicles

32

lysosome

ingests bad things

33

food vacuole

hold food for the plant

34

contractile vacuole

pump excess water out of cell

35

central vacuole

like a storage facility. back up supplies

36

mitochondria

convert energy to forms that cells can use for work

37

chloroplasts

sites of photosynthesis

38

peroxisome

imports its proteins primarily from the cytosol

39

microtubules

shaped like tubes

40

microfilaments

built from molecules of actin, globular protein

41

intermediate filaments

bearing tensions

42

cell wall

plasma desmata

43

extracellular matrix

glycoproteins secreted by the cells

44

collagen

forms strong fibers outside the cells

45

proteoglycans

small core proteins with many carb chains covalently attached
