Monocots and Dicots

Question 1

This refers to the initial stage of growth where a seed sprouts to become a seedling

Answer 1

Germination

Question 2

What are the four structures of a seed?

Answer 2

1. Plumule
2. Radical
3. Cotyledons
4. Seed coat

Question 3

What is the germination process?

Answer 3

1. A root system is established
2. The first shoot and leaves develop from the plumule
3. The cotyledon transform into leaf-life structure known as seed leaves, which can perform photosynthesis until the first true leaf develops

Answer 9

seed

Question 10

This is the outer covering of the ovule ovule where the seed coat is formed

Answer 10

integument

Question 11

What are the two layers of the integument?

Answer 11

testa and tegmen

Question 12

what is the difference between the testa and tegmen?

Question 14

This is the small opening present at one end of the seed coat

Answer 14

Micropyle

Question 15

The seed stalk with which the seed is attached to the fruit body

Answer 15

Funiculus

Question 16

the region from which the seed breaks off from the fruit leaving a scar

Answer 16

Hilum

Question 17

The base of the funiculus that is fused with the integument

This is the tissue that is rich in starch, oil, and protein

Answer 18

Endosperm

Question 19

Two types of seeds

Answer 19

Answer 20

Non-endospermic or exalbuminous

Question 21

This type of seed is characterized by the presence of the endosperm

Answer 21

Endospermic or albuminous
