3
Q
rules of naming system
A
- two parts
=> genus & species - written in italics / underlined
- capitalize genus and lowercase species
4
Q
genus
A
- group of species related to one another
5
Q
shape of cell
- animal
- plant
A
- no fixed shape
- fixed shape
6
Q
nucleus
A
- controls ALL activity of the cell
7
Q
cytoplasm
A
- where chemical reactions take place
8
Q
cell membrane
A
- controls what does in and out of a cell
9
Q
mitochondria
A
- released by respiration
- gives energy
10
Q
cell wall
A
- gives shape
- protects
11
Q
vacuole
A
- contains water and glucose
12
Q
green chloroplasts
A
- contains chlorophyll
- stores starch
13
Q
ribosome
A
- protien systhesis takes place
- found on RER
14
Q
RER
A
- rough endoplasmic reticulum
15
Q
SER
A
- smooth endoplasmic reticulum
16
Q
two types of cells
A
- Prokaryote
- Eukaryote
17
Q
prokaryote
A
- one cell
- no nucleus
18
Q
eukaryote
A
- multiple cells
- nucleus
19
Q
types of substances that move in and out of a cell
A
solid = calcium, protein, glucose
liquid = H2O
gas = CO2, O2
20
Q
diffusion
A
- particles move (gas)
- high to low concentration
- down the concentration gradient
- random movements
- needs to reach equilibrium
21
Q
osmosis
A
- only water movement
- high to low concentration
- down the concentration gradient
- p.p.m
22
Q
P.P.M
A
- partially permeable membrane
- allows certain substances
23
Q
active transport
A
- requires energy
- low to high concentration
- mitochondria
- carrier protein
24
Q
turgid
A
- plant cell fully inflated with water
25
flaccid
- plant cell that is soft and limp through a reduction of pressure inside the cell
26
factors of diffusion rate
- temperature
- surface area
- concentration gradient
- size of particles
27
concentrated solution =
diluted solution =
=> low water potential
=> high water potential
