organelles

Question 1

cell membrane

Answer 1

selective permeable barrier, double layer of phospholipids and proteins, contains cell contents

Question 2

cell wall

Answer 2

provides strength structure and support, rigid outer later of plant cell

Question 3

cytoplasm

Answer 3

gelatinous fluid that fills a cell, protects components from damage, maintain optimal environment

Question 4

mitochondria

Answer 4

generates ATP by chemical respiration, turns glucose into usable energy, membrane bound

Question 5

lysosome

Answer 5

contain digestive enzymes to break down food and worn out cell parts to recycle and make more organelles, digest invaders

Question 6

vacuole

Answer 6

store food water waste and other materials, membrane bound storage sacs, maintain water balance

Question 7

Golgi body

Answer 7

process package and sort proteins and transport them into membrane bound vesicles to where they are needed, receives proteins from ER

Question 8

chloroplast

Answer 8

green plastids, carry out photosynthesis, filled with chlorophyll (photosynthetic pigment)

Question 9

endoplasmic reticulum

Answer 9

outer nuclear membrane, carry proteins and other materials form one part of a cell to another

Question 10

smooth ER

Answer 10

no attached ribosomes, build carbohydrates and lipids, store toxins

Question 11

rough ER

Answer 11

ribosomes attached to surface, produce proteins, may modify proteins from ribosomes

Question 12

nucleus

Answer 12

store information needed to control all cell activity, contains DNA

Question 13

ribosomes

Answer 13

where protein synthesis takes place, assembles amino acids to create proteins

Question 14

nucleolus

Answer 14

found inside the nucleus and produces ribosomes

Question 15

chromatin

Answer 15

tiny strands inside the nucleus that contain instructions for directing the cell’s function
