GERMINATION

Question 1

What are the main parts a seed has?

Answer 1

EMBRYO
FOOD STORE
SSEED COAT (TESTA)

Question 2

What is an embryo in a seed?

Answer 2

young root + shoot that will become an adult plant

Question 3

Why do seeds have a food store?

Answer 3

contains starch for seedling to use until its able to carry out photosynthesis

Question 4

What is the testa?

Answer 4

seed coat -> tough protective outer covering

Question 5

How do seeds utilise food reserves until they are able to carry out photosynthesis?

Answer 5

Glucose used in aerobic respiration to release energy for growth
This continues until seed germinates + can start to photosynthesise independently

Question 6

What is germination?

Answer 6

start of growth of a seed

Question 7

What are the factors required for succesful germination?

Answer 7

WATER
OXYGEN
WARMTH

Question 8

Why is water required for succesful germination?

Answer 8

allows seed to swell up + enzymes in embryo to start working so growth can occur

Question 9

Why is oxygen required for succesful germination?

Answer 9

so energy can be released for germination

Question 10

Why is warmth required for succesful germination?

Answer 10

GERMINATION IMPROVES AS TEMPERATURE RISES
