Robert Hooke (1665)

  • coined the word "cell"

  • found that they appeared as tiny compartments or small fitted rooms

New cards
2
New cards

Anton van Leeuwenhoek (1676)

  • observed tiny living organisms

  • called them "animalcules"

  • first observed red blood cells of animals and sperm cells

New cards
3
New cards

Robert Brown (1831)

observed and coined "nucleus" inside the cells

New cards
4
New cards

Matthias Schleiden (1838)

all plant parts are made up of cells

New cards
5
New cards

Theodor Schwann (1839)

all animal tissues are composed of cells

New cards
6
New cards

Rudolf Virchow (1858)

  • all cells come from pre-existing cells

  • "omnis cellila e cellula"

Three Postulates of Cell Theory

  1. all living organisms are composed of one or more cells

  2. the cell is the basic unit of life

  3. all cells come from preexisting cells

New cards
8
New cards

Prokaryotic Cells

single-celled microorganisms whose cells lack a nucleus and other organelles

New cards
9
New cards

Eukaryotic Cells

multicellular cell or organism that possesses a clearly defined nucleus

New cards
10
New cards

Plant Cell Structure

similar in shape (mostly rectangular or cube shaped), larger than animal cells in size,

New cards
11
New cards

Animal Cell Structure

shape and size vary greatly from irregular to round shapes defined by function

New cards
12
New cards

Three Roles of Cells

  1. produce energy

  2. produce protein

  3. reproduce / make more cells

New cards
13
New cards

Organelles that Produce Energy

mitochondria, cell membrane, vacuole and vesicle, lysosome

New cards
14
New cards

Organelles that Produce Protein

Nucleus, Ribosome, Endoplasmic Reticulum, Golgi Apparatus

New cards
15
New cards

ATP

adenosine triphosphate (ATP), energy-carrying molecule found in the cells of all living things

New cards
16
New cards

cell membrane

  • separates cell from outside

  • controls what enters or leaves the cell

New cards
17
New cards

phospholipid

makes the cell membrane; composed of phosphate head and lipid tail (composed of fatty and phosphoric acid)

New cards
18
New cards

cell membrane

recognizes signals and allows communication between cells

New cards
19
New cards

cytoplasm

jelly-like material holding organelles in place, full of protein

New cards
20
New cards

vacuole and vesicles

  • responsible for transporting materials around the cell

  • food and water storage

New cards
21
New cards

mitochondria

"powerhouse of the cell" makes ATP energy from cellular respiration (is double membraned)

New cards
22
New cards

ATP Formula

sugar + O₂ → ATP

New cards
23
New cards

lysosome

  • responsible for food digestion

  • garbage disposal and recycling

New cards
24
New cards

chloroplasts

make energy and glucose from sunlight through photosynthesis

New cards
25
New cards

Central Dogma of Biology

Nucleus: DNA → RNA → Ribosome → Protein → Vasicle → Golgi Apparatus → Vesicle → Cells

New cards
26
New cards

Nucleus

  • control center of the cell

  • protects DNA

New cards
27
New cards

DNA

contains genetic code, and instructions for building proteins

New cards
28
New cards

Structure of Nucleus

contains: nuclear membrane, nucleolus (ribosome factory), chromosomes

New cards
29
New cards

ribosomes

protein factories, some are free in the cytoplasm, some are attached to ER

New cards
30
New cards

Centrioles

help coordinate cell division in animal cells
