Seeds and Germination Flashcards
Name the parts of this seed
A. Cotyledon
B. Embryo
C. Seed Coat
The outer covering of the seed that protects its internal parts is know as
Seed Coat
Cotyledons are also known as?
Seed Leaves
Based on the number of cotyledons, seeds are divided as ?
Monocotyledon
Dicotyledon
Name the part of the seed that absorbs food from the parent plant and gives good to the growing embryo?
Cotyledon
Give three examples of seeds that have two cotyledons
Gram
Pea
Bean
The part of the seed that develops into a new plant is known as?
Embryo
When the embryo grows it gives rise to two parts, name them
Plumule
Radicle
The outer covering of the seed is the seed coat. This is also known as?
Testa
The development of a seed into a new plant is known as?
Germination
The seed absorbs water through a tiny opening called the
Seed hole
Once the water enters the seed the embryo starts dividing and increasing in size, is this true
yes
water entering the seed through a seed hole, this process is known as?
Imbibition
As the embryo in the seed grows in size, what finally happens to the testa ( seed coat )
It breaks open
After the seed coat breaks open, the part of the seed that grows downward is known as the
Radicle
After the seed coat breaks open the part of the seed that moves upwards is known as the?
Plumule
When do the cotyledons dry up
after the seedling grows new leaves and can make its own food
The process by which plants create their own food is known as?
Photosynthesis
The Radicle forms which part of the plant?
Root
The Plumule forms which part of the plant
Stem and leaves
Other than the number of cotyledons, wht is the main difference between monocotyledons and dicotyledons
Monocotyledons have endosperm. Dicotyledons do not have angiosperms
Cotyledons give nutrition to the growing embryo, endosperms give nutrition to what>
seedling
From which part of the plant do we get the seeds
From the OVULES after fertilization
The ovules are produced from which part of the plant
Ovary
Do dicotyledons have endosperm
No
Do monocotyledons have endosperm
yes
