Cell Organelles

Question 1

Cell membrane

Answer 1

A border/gate that lets certain things in and out (semi-permeable).

Question 2

Vesicle

Answer 2

Small sac made by the cell mebrane made through endocytosis and exocytosis. It moves substances/particles into or out of the cell.

Question 3

Chloroplast

Answer 3

• conducts photosynthesis
• takes glucose made in the day and uses it as its source of energy at night (since there’s no sun)
• plant cell only

Question 4

Mitochondria

Answer 4

• where cell respiration occurs, making ATP (adenosine triphosphate)
• runs on glucose as its main energy source

Question 5

Nucleus

Answer 5

• contains DNA (eukaryotic cells only) and keeps it safe
• small blob in the nucleus is the nucleolus, the specific part where the DNA is located

Question 6

Endoplasmic reticulum

Answer 6

• attached to the nucleus
• transports molecules around
• two types: rough and smooth
• rough endoplasmic reticulum has ribosomes attached which produces proteins for the rest of the cell to function which are transported
• smooth endoplasmic reticulum helps make and process lipids
• forms channels and compartments in cytoplasm to separate different organelle functions

Question 7

Golgi Apparatus

Answer 7

• packages chemicals and proteins into vesicles which are pinched off for storage or secretion
• a type of vesicle produced is the lysosome

Question 8

Ribosome

Answer 8

• not membrane bound organelle
• makes proteins

Question 9

Vacuole

Answer 9

• acts as storage of materials
• plants cell has one large vacuole
• animal cells has small vacuole scattered or none at all

Question 10

Cell Wall

Answer 10

• extra layer in plant cells for further protection
• keep it’s structure/shape
• only plant cells
