Question 1

Few crops that dominate the agricultural landscape.

Answer 1

Rice, wheat and potatoes

Question 2

It is the embryonic stage of plant life cycle.
An important part of flowering plant (give rise to a new plant).
Have different shapes and sizes (round,wrinkled, winged or hairy).
They are in dormant condition until they receive adequate sunlight, water and soil.

Answer 2

Seeds

Question 3

The growth of the plant from a seeds is known as?

Answer 3

Germination

Question 4

The protective covering that can help seeds remain viable for long periods of time.

Answer 4

Seed Coat

Question 5

It is the outer thick layer of seed coat that prohibit the entry of sunlight, water and parasites with in the seeds. It also prevent the germination of seeds during unfavorable environmental condition.

Answer 5

Testa

Question 6

The second inner thin protective layer of seed coat present within the testa. Just like the testa, it also protects the seed and its contents.

Answer 6

Tegmen

Question 7

The nutritive tissue of the seed, provides nutrients to the seed in the form of starch, carbohydrates and proteins to support the embryo during germination.

Answer 7

Endosperm

Question 8

It is coconut water, not to be confused with coconut milk, which is harvested from the flesh of fully developed coconuts.

Answer 8

Coconut Endosperm

Question 9

The most important part of a seed, developed from the fertilized egg. It comprises the following parts:
Epicotyl
Hypocotyl
Radicle
Cotyledons

Answer 9

Embryo

Question 10

The tiny shoot of an embryo, from which the entire system develops.

Answer 10

Epicotyl

Question 11

The tip of the epicotyl is called?

Answer 11

Plumule

Question 12

A plantlet that giving rise to the first true leaves and is grown into shoot plant giving rise to several leaves, branches, flowers, and seeds.

Answer 12

Plumule

Question 13

The stage of transition for the growing shoot and root of the embryo, the stem of a germinating seedling.

Answer 13

Hypocotyl

Question 14

The part of a plant embryo that develops into the primary root, tiny roots in the embryo, first root of seed.

Answer 14

Radicle

Question 15

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

Answer 15

Cotyledons

Question 16

The first part of a plant to emerge from the seed. They contain reserve food material that provides nourishment to the developing seedling. The function of it is to store food for the growing embryo.

Answer 16

Cotyledons

Question 17

These comprise a single cotyledon emerging from the seed on germination (cereals) rice, corn, wheat.

Answer 17

Monocotyledonous seeds

Question 18

These comprise two cotyledons emerging from the seeds on germination.

Answer 18

Dicotyledonous Seeds

Question 19

When do photosynthetic system starts?

Answer 19

When it is color green or it has green color green pigment. Or once the leaves appear.

Question 20

Any of a group of plants that produce seeds and include the gymnosperms and flowering plants.

Answer 20

Spermatophytes

Question 21

Large group of vascular seed plants, the seeds do not develop enclosed within an ovary but are usually borne exposed on the surfaces of reproductive structures, such as cones. (Ex. conifers and cycads.

Answer 21

Gymnosperms or naked seeded

Question 22

Flowering plant, any of about 300,000 species of flowering plants, the largest and most diverse group within the kingdom Plantae. It represent approximately 80 percent of all the known green plants now living.

Answer 22

Angiosperm

Question 23

Are the smallest seeds which are only 1/300th of an inch (85 micrometer) long- smaller than can be seed by the unaided eye.

Answer 23

Epiphytic orchid seed

Question 24

Are vascular seed plants in which the ovule (egg) is fertilized and develops into a seed in an enclosed hollow ovary.

Answer 24

Angiosperm

Question 25

These seeds are dispersed in the air like minute dust particles. They lack endosperm, tiny, underdeveloped embryos.

Answer 25

Epiphytic orchid seed

Question 26

Nut is technically a fruit, but we usually eat the seed and discharge the fruit (shell). (T or F)

Answer 26

True

Question 27

Technically, grains are seeds that are fused to the ovary wall, so they are fruits, even though most of what we eat (nearly all of the nutritional value) is the seed. (T or F)

Answer 27

True

Question 28

Pine nuts, almonds and Brazil nuts are also seeds even though none of this comes from a nut. (T or F)

Answer 28

True
