Organelles

Question 1

Nucleus

Answer 1

Contains DNA, directs cellular activity, surrounded by nuclear envelop with pores that allow transports of materials

Question 2

Cytoplasm

Answer 2

Gel like substance inside cell membrane, organelles suspended in it, allows for cytoplasmic streaming(speed in transport of molecules)

Question 3

Cell wall

Answer 3

Found in plants, not in animal cells, rigid frame around cell, strength and support

Question 4

Chloroplasts

Answer 4

Found only in plants and some protists, contains chlorophyll; site of photosynthesis, energy from the sun converts to convert c02 and water jnto sugars

Question 5

Vacuoles/vesicles

Answer 5

Membrane bound structures, store nutrients, productions of secretion and fats, plant cells have one central vacuole. Vesicles transport material through the cell

Question 6

ER

Answer 6

Series of interconnected small tubes(tubules), materials transported via tubes, used for protein synthesis. The smooth ER is responsible for synthesis of lipids=fat/oil production. Rough ER has ribsomes on it and is responsible for protein synthesis

Question 7

Ribosomes

Answer 7

Can be on cytoplasm or protein synthesis, protein synthesis

Question 8

Lysosome

Answer 8

Membrane bound sacs, digestion, defence against bacteria, destruction of damaged organelles DIGESTIVE SYSTEM OF THE CELL, located in cytoplasm

Question 9

Golgi apparatus

Answer 9

Flat, disc shaped sacs, secretion, transports proteins and nutrients, receives from ER, transports out of cell

Question 10

Mitochondria

Answer 10

Reactions occur to convert chemical energy into energy the cell can use through cellular respiration
