Cell Theory point 1

All organisms are composed of at least one cell

New cards
2
New cards

Cell theory point 2

The cell is the basic unit of structure+organization in organisms

New cards
3
New cards

Cell theory point 3

All cells come from preexisting cells

New cards
4
New cards

Leeuwenhoek

1st guy to view organisms/bacteria 1673

New cards
5
New cards

Robert Hooke

Coined the term “the cell”

New cards
6
New cards

Endosymbiotic Theory

Some organelles within cells were at one time free living cells themsevels

New cards
7
New cards

Plant cell>animal cell>bacteria

Cells in order of size!

New cards
8
New cards

Cells

Smallest unit that can carry out all process of life

New cards
9
New cards

Surface to Volume Ratio

The reason why cells are small, and allows them to easily exchange food and waste. As cell size ⬆️, volume ⬆️ faster than Surface Area

New cards
10
New cards

Prokaryotic Cells

The 1st ever cell! Had no nucleus, simplest type of all! Ex. E-Coli, Salmonella, Bacteria

New cards
11
New cards

Eukaryotic Cells!

The supreme type of cell! Has a nucleus, membrane bound organelles, super complex. Ex. plants, animals, fungi, protists

New cards
12
New cards

Drawing Magnification

=measured size of drawing/size of specimen

New cards
13
New cards

1 Millimeters

1000 micrometers

New cards
14
New cards

1 centimeter

10 millimeters

New cards
15
New cards

Organism Actual Size

  1. measure size on paper in micrometers

  2. divide by magnification

New cards
16
New cards

Organelles

The “organs” of a cell. Prokaryotes have a few (ribosomes). Eukaryotes have many, usually surrounded by a membrane

New cards
17
New cards

Cell Membrane ( aka Plasma membrane )

A lipid bilayer that protects and supports cells, controls what enters/leaves cells,

New cards
18
New cards

Cell Wall

Found in plant and protist walls, main function is protection, allows dissolved water to pass through substances

New cards
19
New cards

The Nucleus

The brain of the cell, controls most of the activity per cell, 1 per cell. Contains DNA + other molecules for the cell

New cards
20
New cards

DNA

The coded instructions for making proteins

New cards
21
New cards

Nucleolus

Small, dense region in the middle of the nucleus where ribosomes are formed

New cards
22
New cards

Cytoplasm

The cell’s juice! Moves materials throughout the cell

New cards
23
New cards

Ribosomes

Makes proteins in the cell, may be free in cytoplasm or attached to ER

New cards
24
New cards

Golgi Apparatus (bodies)

Stacks of membranes used for storing, modifying, or packaging

New cards
25
New cards

Endoplasmic Reticulum

Series of folded membranes that form sacs or tubes that help moves things throughout the cell

New cards
26
New cards

Smooth ER

No ribosomes, makes lipids, detoxifies drugs

New cards
27
New cards

Rough ER

Ribosomes make it look rough, the ribosomes make the proteins

New cards
28
New cards

Lysosomes

Made by Golgi Apparatus, full of digestive enzymes to digest unwanted particles, the clean up crew

New cards
29
New cards

Peroxisomes

Filled with enzymes to digest toxic substances (type of Lysosomes)

New cards
30
New cards

Vacuoles

Membrane bound compartments that store food, water, or waste.

New cards
31
New cards

Chloroplasts

Found in Eukaryotic plant/some protist cells. Capture light energy and convert it into chemical energy during photosynthesis-reason why plants 🌱 are green

New cards
32
New cards

Mitochondria

Energy producers-the “powerhouse” of the cell! Converts chemical energy into usable energy

New cards
33
New cards

Cytoskeleton

Overlapping network of filaments and fibers that support the cell and help maintain its shape

New cards
34
New cards

Centrioles

Help to organize the cell during cell division. They migrate to either side of the cell and help pull it apart-only in animal cells

New cards
35
New cards

Flagellum

Extension of the cytoskeleton- allows movement, main source of transportation for cells (the little tail some cells have)

New cards
36
New cards

Cilia/Pili

Extension of the cytoskeleton- allows things to move around the cell (only in so me animals cells + prokaryotes)

New cards
37
New cards

High to low concentration!

Molecules move from?

New cards
38
New cards

isotonic

When the concentration of two solutions are equal

New cards
39
New cards

hypertonic

the solution with the higher consecration of solutes

New cards
40
New cards

Hypotonic

The solution with the lower concentration of solution

New cards
41
New cards

osmosis

diffusion of molecules through a semipermeable membrane from a place of higher concentration to a place of lower concentration until the concentration on both sides is equal

New cards
42
New cards

What’s up embedded in the Semi-permeable membrane of the cell

Lipid molecules, cholesterol, carbohydrates, and protiens

New cards
43
New cards

Protein channels

Nonstatic doorways on the cell membrane that allow cells to enter/exit

New cards
44
New cards

Facilitated Diffusion

Diffusion that has the aid of a protein channel

New cards
45
New cards

Passive Transport

Movement of molecules that requires no ATP

New cards
46
New cards

To move stuff in bulk

Purpose of Endocytosis and Exocytosis?

New cards
47
New cards

ENdocytosis

Part of the surface membrane surrounding the bulk that’s ENtering-active

New cards
48
New cards

EXocytosis

Part of the surface membrane that helps the bulk EXit-active

New cards
49
New cards

Phagocytosis

Type of Endocytosis that takes in big particles

New cards
50
New cards

Pinocytosis

Type of Endocytosis that takes in liquids

New cards
51
New cards

Receptor-mediated Endocytosis

Type of Endocytosis that takes in the low concentration particle that the cell needs

New cards
52
New cards

Sodium/Potassium Pump

A type of protein channel that allows sodium particles (3 at a time) to exit the cell and potassium particles (2 at a time) to enter the cell. Requires ATP to pump therefore active

New cards
53
New cards

diffusion

the process in which there is movement of a substance from an area of high concentration of that substance to an area of lower concentration

New cards
54
New cards

Semi-permeable membrane (SPM)

A membrane that allows some particles to naturally flow through- a Holy Membrane 😇
