A

All cells take in food, get rid waste, and reproduce

1-plasma membrane
2- nucleus
3- cytoplasm

Q

Plasma membrane

A

Bilayer of lipids & proteins

Job- allow materials to enter/exit

Semi permeable- only specific materials may enter and exit through pores & protein channels

Nucleus

A

Job- controls cell activity

Inside:

chromatin are long strands of DNA, holds info to make proteins

Nucleolus- makes ribosomes

Q

Describe the protein shipment

A

1-nucleolus makes ribosomes
2-ribosomes travels through rough ER making proteins
3-protein is brought to the Golgi body by a protective vesicle. Then the Golgi body sorts & packages the protein.
4- vesicle release the protein from the cell

Q

Allows materials to enter/exit a cell?

A

Cell membrane

17
Q

Links chains of amino acids together?

A

Ribosomes

18
Q

Mitochondria

A

Job- create ATP (energy molecule) in a process called cellular respiration

Endosymbiosis theory; once free living organisms that became parts of modern cells

Evidence
Own DNA and ribosomes
Make proteins
Replicate

19
Q

Lysosome

A

Contains digestive enzymes

Jobs
Break down food
Kill pathogens
Autolysis- destroy dying cell

20
Q

Cilia & flagella

A

Job- movement

Cilia- short hair like extensions (numerous)

Flagella- long whip like extensions (very few)

21
Q

Cell wall

A

Outermost layer of plant, fungi and bacteria cells

Job- adds support for growth

Made of tough cellulose- hard to digest

22
Q

Chloroplast

A

Job- perform photosynthesis

Chlorophyll molecules absorb sunlight & concert water and CO2 info sugars

23
Q

Vacuole

A

Job- stores food, water, waste, color pigments

Plant cells: large central vacuole

Animal cells: scattered smaller vacuoles

24
Q

What are the two types of cells?

A

Prokaryotic (bacteria and archaea) & Eukaryotic (plants and animals, fungi)

25
Q

Cytosol

A

Fluid inside the cell membrane

26
Q

Centriole

A

Spindle
