Bio intro to cells

Question 1

Cell Membrane

Answer 1

Semi-permeable layer that allows only certain substances to go through. Is made of a phospholipid bi-layer

Question 2

Centrioles

Answer 2

Organizes microtubules for cell division.

Question 3

Chloroplasts

Answer 3

Energy from sunlight

Question 4

Amyloplast

Answer 4

Glucose/polymer manufacture through starch consumption/storage

Question 5

Nucleolus

Answer 5

RNA creation. RNA serves as signalling element

Question 6

Ribosome

Answer 6

Encoded with RNA from nucleolus, which it then uses to manufacture proteins.

Question 7

Nucleus

Answer 7

Contains many nuclear bodies used for encoding DNA/RNA for instruction transfer. Nucleolus included in this.

Question 8

Nuclear Membrane

Answer 8

Controls what enters nucleus

Question 9

Vacuoles

Answer 9

Storage system

Question 10

Lysosome

Answer 10

waste storage

Question 11

Cytoplasm

Answer 11

basic metabolic medium of the cell

Question 12

Mitochondria

Answer 12

generates ATP for cell energy from glucose products

Question 13

Rough E.R

Answer 13

manufactures proteins and enzymes with ribosomes attached. Works with ribosomes, and transfers products.

Question 14

Smooth E.R

Answer 14

Detoxification and lipid/carbohydrate synthesis.

Question 15

Golgi Body

Answer 15

Packages proteins into vesicles and moves those around the cell

Question 16

Peroxisome

Answer 16

involved in oxidative reactions

Question 17

Peripheral Proteins

Answer 17

Proteins that stick into or out of the cell membrane. Useful as enzymes and support cells.

Question 18

Glycoprotein

Answer 18

A surface protein used for recognition and pathogen defence

Question 19

Glycolipid

Answer 19

A surface protein used for recognition and pathogen defence

Question 20

Pinocytosis

Answer 20

Vesicles are used to envelop dissolved materials, and to pull them inside the cell

Question 21

Phagocytosis

Answer 21

envelopment of larger materials to bring them into the cell. used in immune responses
