Monocots and Dicots Flashcards
This refers to the initial stage of growth where a seed sprouts to become a seedling
Germination
What are the four structures of a seed?
- Plumule
- Radical
- Cotyledons
- Seed coat
What is the germination process?
- A root system is established
- The first shoot and leaves develop from the plumule
- The cotyledon transform into leaf-life structure known as seed leaves, which can perform photosynthesis until the first true leaf develops

This part of a seed becomes the first plant shoot
Plumule
This part of a seed forms the first shoot
Radical
This part of a seed acts as a food storage for the new plant until it can perform photosynthesis
Cotyledons
This part of a seed provides a protective layer around the seed
Seed coat
What are the requirements for germination?
- soil
- water
- sunlight
- carbon dioxide
- oxygen
- warm temperature
This refers to a structure that encloses the embryo of a plant in a protective outer covering
seed
This is the outer covering of the ovule ovule where the seed coat is formed
integument
What are the two layers of the integument?
testa and tegmen
what is the difference between the testa and tegmen?
testa - thick outer layer
tegmen- delicate inner layer
What are the four parts of a seed coat?
micropyle
funiculus
hilum
raphe
This is the small opening present at one end of the seed coat
Micropyle
The seed stalk with which the seed is attached to the fruit body
Funiculus
the region from which the seed breaks off from the fruit leaving a scar
Hilum
The base of the funiculus that is fused with the integument
Raphe
This is the tissue that is rich in starch, oil, and protein
Endosperm
Two types of seeds
-Non-endospermic or exalbuminous
-Endospermic or albuminous
This type of seed is characterized by the complete absence of the endosperm
Non-endospermic or exalbuminous
This type of seed is characterized by the presence of the endosperm
Endospermic or albuminous
This protects the seed from physical and mechanical damage
Seed coat
This stores the reserve foods that provide nourishment to the developing plant
Endosperm
This protects the embryo, the next part of the seed, by acting as the mechanical barrier
Endosperm
This refers to the young plant that is developing inside the seed coat
embryo
What are the parts of an embryo of a seed
- epicotyl
-hypocotyl
-radicle
-cotyledons
What are the two types of cotyledons present in flowering plants?
monocots and dicots
refers to embryo with one cotyledon
monocot
refers to embryo with two cotyledons
dicots
This gives rise to a complete new plant
embryo
this refers to the tiny shoot of an embryo, from which the entire shoot system develops
Epicotyl
refers to the stage of transition for the growing shoot and root of the embryo
hypocotyl
the tiny root of the embryo
radicle
the leaves of the embryo that provide nourishment to the developing plant
cotyledons
this is produced when beans absorb water
Gibberlin
this triggers the production of amylase, breaking down the starch to use for the germination process
Gibberlin
This is the germination for dicots
Epigeal
This is the germination for monocots
Hypogeal
