SEEDS
A seed is an embryonic plant enclosed in a protective outer covering. The formation of the seed is part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants. Seeds are the product of the ripened ovule, after fertilization by pollen and some breed within the plant. The embryo develops from the zygote, and the seed coat from the integuments of the ovule. Seeds have been an important development in the reproduction and success of gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses, and liverworts, which do not have seeds and use water-dependent means to grow.
Seed plants now dominate biological niches on land, from forests to grasslands, both in hot and cold climates. The term "seed" also has a general meaning that antedates the above anything that can be sown, e.g., “seeds’’ potatoes, “seeds" of corn or sunflower "seeds". In the case of sunflower and corn "seeds'l, what is sown is the seed enclosed in a shell or husk, whereas the potato is a tuber. In the angiosperms (flowering plants), the ovary ripens to a fruit which contains the seed and serves to disseminate it. Many structures commonly referred to as 'seeds" are actually dry fruits. Sunflower seeds are sold commercially while still enclosed within the hard wall of the fruit, which must be split open to reach the seed. Different groups of plants have other modifications; the so-called stone fruits (such as the peach) have a hardened fruit layer (the endocarp) fused to and surrounding the actual seed. Nuts are the one-seeded, hard-shelled fruit of some plants with an indehiscent seed, such as an acorn or hazelnut.
Seeds are produced in several related groups of plants, and their manner of production distinguishes the angiosperms ("enclosed seeds") from the gymnosperms ("naked seeds"). Angiosperm seeds are produced in a hard or fleshy structure called a fruit that encloses the seeds for protection in order to secure healthy growth. Some fruits have layers of both hard and fleshy material. In gymnosperms, no special structure develops to enclose the seeds, which begin their development "naked" on the bracts of cones. However, the seeds do become covered by the cone scales as they develop in some species of conifer.
Seed production in natural plant populations varies widely from year to year in response to weather variables, insects and diseases, and internal cycles within the plants themselves. Over a 20-year period, for example, forests composed of loblolly pine and short leaf pine produced from 0 to nearly 5 million sound pine seeds per hectare. Over this period, there were six bumper, five poor, and nine good seed crops, when evaluated for the production of adequate seedlings for natural forest reproduction. Angiosperm (flowering plants) seeds consist of three genetically distinct constituents: the embryo formed from the zygote, the endosperm, which is normally triploid, the seed coat from tissue derived from the maternal tissue of the ovule. In angiosperms, the process of seed development begins with binary impregnation, which involves the fusion of two male gametes with the egg cell and the central cell to form the primary endosperm and the zygote. Right after fertilization, the zygote is mostly inactive, but the primary endosperm divides rapidly to form the endosperm tissue. This tissue becomes the food, and the young plant will consume until the roots have developed after germination.
Questions 7-13
Do the following statements agree with the Information given in the Reading Passage?
TRUE If the statement agrees with the information.
FALSE If the statement contradicts the information.
NOT GIVEN If there is no Information on this.
7. The seeds cannot nurture inside a plant.
Answer: FALSE
Supporting statement: Seeds are the product of the ripened ovule, after fertilization by pollen and some breed within the plant
Keywords: Seeds, plant
Keyword Location: Para 1, Lines 3-4
Explanation: The seed can develop inside the plant according to the passage.
8. Some seedless plants depend on water resources to propagate.
Answer: TRUE
Supporting statement: which do not have seeds and use water-dependent means to grow.
Keywords: water, dependent
Keyword Location: Para 1, Line 8
Explanation: Plants like ferns, mosses, and liverworts without seeds depend on water to grow.
9. Seed plants used to raise well in hot environment as compared to cold weather in the ancient times.
Answer: NOT GIVEN
Explanation: No information about the above-mentioned statement is given in the passage.
10. Sunflower seeds are sold commercially by taking them out of their shell.
Answer: FALSE
Supporting statement: Sunflower seeds are sold commercially while still enclosed within the hard wall of the fruit, which must be split open to reach the seed.
Keywords: Sunflower, split
Keyword Location: Para 2, Lines 7-8
Explanation: Commercially sold sunflower seeds are usually sold enclosed, as mentioned in the passage.
11. Gymnosperm kernels are formed in a rigid or plump fruit.
Answer: FALSE
Supporting statement: Some fruits have layers of both hard and fleshy material. In gymnosperms, no special structure develops to enclose the seeds,
Keywords: hard and fleshy, gymnosperms
Keyword Location: Para 3, Lines 4-5
Explanation: According to the text, gymnosperm kernels are not formed in a rigid or plump fruit as there is no special structure present that develops to enclose the seed.
12. The angiosperms' progression of seed expansion requires two stages of insemination.
Answer: TRUE
Supporting statement: which involves the fusion of two male gametes with the egg cell and the central cell to form the primary endosperm and the zygote.
Keywords: gametes, endosperm
Keyword Location: Para 4, Lines 10-11
Explanation: According to the text, angiosperms go through two stages of insemination, one where the endosperm or the zygote forms and the second one where the endosperm divides rapidly to form the endosperm tissue.
13. Zygote remains sedentary immediately after fertilization.
Answer: TRUE
Supporting statement: Right after fertilization, the zygote is mostly inactive
Keywords: fertilization, zygote
Keyword Location: Para 4, Line 11
Explanation: According to the passage, the zygote right after fertilization remains inactive.
