Homework Answers
The plant part is not a source of fibers at an industrial scale is D. FLOWER
The plant fibres of industrial value are cotton, jute, hemp and Flax. Plant fibres are composed of cellulose and to a less extent Lignin. Plant fibres can be extracted from various parts of plants at an industrial scale such as
Stem: Flax, jute, Hemp, Bamboo, etc.,
Seeds: Cotton, milk weed
Fruit: Coir, Seed Hair
Leaves: Sisal, Manila, Abaca
But the plant fibres cannot be extracted from flower.

A purple flowering, smooth seed dihybrid plant (genotype PpSs) is test crossed with a white flowering, wrinkled seed plant (genotype ppss). These produce progeny in the following numbers of four phenotypes: 24:76:74:26 (purple flower + smooth seed coat: purple flower + wrinkled seed coat: white flower + smooth seed coat: white flower + wrinkled seed coat). a) Explain how ratios of progeny show that the two genes are linked. b) How many map units separate the colour and seed coat...

Describe (in words), the life cycle of an Angiosperm starting with a seed that is germinating right now, following that seedling though its life until it produces a seed of its own that will complete one full generation. Be sure to explain the steps involved in this plant’s life cycle related to its alternation of generations. Describe the reproductive structures produced along the way, using proper terminology that we have repeatedly discussed in the context of plant life cycles. Be...

Part B - Deducing genotypes of crossed parents A plant grown from a [round, yellow] seed is crossed with a plant grown from a [wrinkled, yellow] seed. This cross produces four progeny types in the F [round, yellow], [wrinkled, yellow], [round, green], and [wrinkled, green]. Use this information to deduce the genotypes of the parent plants. Indicate the genotypes by dragging the correct label to the appropriate location.

on what part of the frond are the sori located?
ACTIVITY 9: In angiosperms, fruits play an important role in seed dispersal. Plant biologists recognize different types of fruit, 11 of which are described in the table below. Dried fruits can be further classified as indehiscent (the fruit/pod does not split open when ripe) or dehiscent (fruits/pods split open when mature)." Examine the provided examples of fruits.
