2. Theodore Schwann

3. Rudolf Virchow

Front 7

What did Mat Thais Schleiden do for the cell theory?

Back 7

Schlseiden studied the plant-based part of the cell theory. He realized that all plants are made up of cells.

Front 8

What did Theodore Schwann do for the cell theory?

Back 8

Schwann came to the conclusion that all animals were made up of cells

Front 9

What did Rudolf Virchow do for the cell theory?

Back 9

Virchow proved that all existing cells arise from pre-existing cells.

Front 10

Label the microscope

Back 10

Front 11

when would you use a dry mount?

Back 11

when you are working with inanimate objects or things that do not need water to live.

Front 12

when would you use a wet mount?

Back 12

when you are working with live cells, it lets the cells become hydrated, keeping them alive longer, therefore making them be able to move.

Front 13

name the 9 parts to an animal cell

Back 13

1. cell membrane

2. cyptoplasm

3. ribosomes

4.golgi apparatus

5. endoplasmic reticulum

6. mitochondria

7. nucleus

8. vacuoles

9. lysosomes

Front 14

name the 10 parts to a plant cell

Back 14

1. cell membrane

2. cyptoplasm

3. ribosomes

4.golgi apparatus

5. endoplasmic reticulum

6. mitochondria

7. nucleus

8. vacuole

9. chloroplasts

10. cell wall

Front 15

what is the cell membrane?

Back 15

The cell membrane surrounds and holds the cell contents together; controls movement into and out of the cell

Front 16

what is the nucleus?

Back 16

The nucleus is the control centre of the cell surrounded by a nuclear membrane

Front 17

what are the vacuoles (animal cell)

Back 17

storage compartments for the cell that stores water, nutrients, waste, and other substances.

Front 18

what is the cyptoplasm?

Back 18

Jelly like material that fills the cell and surrounds the organelles. food and oxygen move through the cytoplasm to get to the organelles.

Front 19

what are ribosomes?

Back 19

ribosomes are tiny organelles that help make proteins. There are many in the cyptoplasm.

Front 20

what is the endoplasmic reticulum?

Back 20

a folded organelle that makes proteins

Front 21

what is the golgi apparatus?

Back 21

a folded organelle that combines proteins made by the endoplasmic reticulum and delivers them to the rest of the cell and outside the cell

Front 22

what are mitochondria's?

Back 22

the powerhouses of the cell. these organelles break down food particles and release their stored energy. the cell uses its energy to fuel all of its activities.

Front 23

what is a vacuole?? (plant cell)

Back 23

a large, sac-like organelle that stores excess food, waste, and other substances.

Front 24

what are chloroplasts? (plant cell)

Back 24

membrane-bound organelles that contain a green substance (pigment) called chlorophyll.

Front 25

what is the cell wall? (plant cells)

Back 25

the rigid structure that surrounds the cell membrane. it provides the cell with strength and support. materials pass in or out through pores in the cell wall.

Front 26

what are lysosomes?

Back 26

organelles that break down food and digest wastes.

Front 27

whats a micrograph?

Back 27

A micrograph is a photo taken by means of a microscope

Front 28

what does permeable mean?

Back 28

allowing fluids to pass through

Front 29

what does impermeable mean?

Back 29

not allowing liquids to add through

Front 30

what does selective permeability mean?

Back 30

selective permeability is when some particles, ions, or water can cross the membrane.

Front 31

give an example of selective permeability

Back 31

1. coffee filters let the water go through but not the coffee ground

2. window screens let air and liquids in, but not solid things such as bugs and birds

Front 32

give an example of an impermeable thing

Back 32

1. plastic

2. tin foil

3. metal

Front 33

give an example of a permeable thing

Back 33

1. cotton

2. net/mesh

Front 34

what are the 2 types of cellular transport?

Back 34

1. Diffusion

2. Osmosis

Front 35

what is diffusion?

Back 35

Diffusion is the movement of particles from an area of high concentration to an area of low concentration

Front 36

What is a concentration gradient?

Back 36

the difference in concentration between two areas

Front 37

Give an example of diffusion

Back 37
