Q

What is the germination process?

A
  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

16
Q

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

A

Hilum

17
Q

The base of the funiculus that is fused with the integument

A

Raphe

18
Q

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

A

Endosperm

19
Q

Two types of seeds

A

-Non-endospermic or exalbuminous
-Endospermic or albuminous

20
Q

This type of seed is characterized by the complete absence of the endosperm

A

Non-endospermic or exalbuminous

21
Q

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

A

Endospermic or albuminous

22
Q

This protects the seed from physical and mechanical damage

A

Seed coat

23
Q

This stores the reserve foods that provide nourishment to the developing plant

A

Endosperm

24
Q

This protects the embryo, the next part of the seed, by acting as the mechanical barrier

A

Endosperm

25
Q

This refers to the young plant that is developing inside the seed coat

A

embryo

26
Q

What are the parts of an embryo of a seed

A
  • epicotyl
    -hypocotyl
    -radicle
    -cotyledons
27
Q

What are the two types of cotyledons present in flowering plants?

A

monocots and dicots

28
Q

refers to embryo with one cotyledon

A

monocot

29
Q

refers to embryo with two cotyledons

A

dicots

30
Q

This gives rise to a complete new plant

A

embryo

31
Q

this refers to the tiny shoot of an embryo, from which the entire shoot system develops

A

Epicotyl

32
Q

refers to the stage of transition for the growing shoot and root of the embryo

A

hypocotyl

33
Q

the tiny root of the embryo

A

radicle

34
Q

the leaves of the embryo that provide nourishment to the developing plant

A

cotyledons

35
Q

this is produced when beans absorb water

A

Gibberlin

36
Q

this triggers the production of amylase, breaking down the starch to use for the germination process

A

Gibberlin

37
Q

This is the germination for dicots

A

Epigeal

38
Q

This is the germination for monocots

A

Hypogeal
