Parts Of The Cell

Question 1

Plasma membrane

Answer 1

Made of a phospholipid bilayer (hydrophilic head, hydrophobic tail). Is selective permeabile

Question 2

Cytoplasm

Answer 2

Made up of cytosol and stores the cell organelles

Question 3

Ribosomes

Answer 3

The site of proteins synthesis, ribosomal RNA.

Question 4

Rough endoplasmic reticulum

Answer 4

The ribosomes are on the RER make proteins that are secreted from the cell; makes the cells membranes.

Question 5

Smooth endoplasmic reticulum

Answer 5

Lipid and steroid synthesis, lipid, metabolism, and drug detoxification

Question 6

Golgi apparatus

Answer 6

Packages, modifies, and segregates proteins for secretion from the cell

Question 7

Lysosomes

Answer 7

Acid hydrolasesfor intracellular digestion

Question 8

Mitochondria

Answer 8

Powerhouse of the cell. ATP synthesis.

Question 9

Peroxisomes

Answer 9

Oxidase enzymes (catalase) , detoxify and breakdown, hydrogen peroxide

Question 10

Microfilaments

Answer 10

Actin, muscle contraction, cellular movement, cytoskeleton, cell division

Question 11

Intermediate filaments

Answer 11

Protect cell from mechanical stress, and help organize cells organelles. The stable cytoskeletal elements; resist tension forces acting on the cell

Question 12

Microtubules

Answer 12

Give cell shape and do intracellular and cellular movement, centrioles. Make up cilia and flagella

Question 13

Centrioles

Answer 13

Forms spindle fibers (act as an anchor), cilia, and flagella. Made of microtubules

Question 14

Nucleus

Answer 14

Control center of the cell; responsible for transmitting, genetic information in providing the instructions for proteins synthesis

Question 15

Nuclear envelope

Answer 15

Contains pores, regulates passage of substances

Question 16

Nucleoli

Answer 16

Site of ribosome subunit manufacture

Question 17

Chromatin

Answer 17

DNA and histone proteins
