Match the following flower parts with their functions:
Sepals = Enclose and protect the flower before it opens and will sometimes close over the flower at night Petals = Most obvious part of the flower, large, variously shaped, and bright to attract pollinators Stamens = Male part of the plant and consists of two parts: anther and filament Carpel = Female part of the plant and consists of three parts: stigma, style, and ovary
Match the following reproductive methods with their descriptions:
Sexual reproduction = Involves the fertilization of gametes Asexual reproduction = Reproduction not involving gametes
Match the following flower parts with their components:
Stamens = Consists of anther and filament Carpel = Consists of stigma, style, and ovary Anther = Produces pollen which forms male gametes Ovary = Has one or more ovules which contain the embryo sac
Match the following flower parts with their roles in sexual reproduction:
Stigma = Catches pollen Style = Connects the stigma to the ovary and holds it in a suitable position to collect the pollen Ovary = Has one or more ovules which contain the embryo sac Anther = Produces pollen which forms male gametes
Match the following flower parts with their roles in asexual reproduction:
Sepals = Enclose and protect the flower before it opens and will sometimes close over the flower at night Petals = Large, variously shaped, and bright to attract pollinators Stamens = Male part of the plant and consists of two parts: anther and filament Carpel = Female part of the plant and consists of three parts: stigma, style, and ovary
Match the following plant processes with their descriptions:
Dormancy = Allows plants to avoid adverse conditions and gives seeds time to disperse and mature Germination = Requires water, oxygen, suitable temperature, and food reserves Asexual Reproduction = Results in genetically identical offspring Practical Investigation = Shows the effect of water, oxygen, and temperature on germination
Match the following methods with their purpose in plant propagation:
Soaking, abrasion, and chemical treatments = Break seed dormancy Stem and root tubers, bulbs, and plantlets = Natural propagation methods Cuttings, layering, grafting, and micropropagation = Artificial propagation methods Starch agar plate experiment = Demonstrates digestive activity during germination
Match the following stages of germination with their activities:
Root and shoot growth = Germination stages Photosynthesis = Germination stages Weight gain = Germination stages Optimizing storage conditions and sowing times = Use of dormancy in agriculture
Match the following practical investigations with their demonstrated concepts:
Effect of water, oxygen, and temperature on germination = Practical investigation Using starch agar plates to demonstrate digestive activity during germination = Practical investigation Seeds need water, oxygen, and the correct temperature for germination = Investigation concept Natural propagation methods include stem and root tubers, bulbs, and plantlets = Demonstrated concept
Match the following plant propagation concepts with their examples:
Dormancy = Optimizing storage conditions and sowing times Asexual reproduction = Artificial propagation methods include cuttings, layering, grafting, and micropropagation Germination = Another practical involves using starch agar plates to demonstrate digestive activity during germination Practical investigation = The investigation shows that seeds need water, oxygen, and the correct temperature for germination
Match the following parts of a flower with their functions in plant reproduction:
Egg sac = Contains the egg cell and two polar nuclei which form the endosperm Receptacle = Thickened part of the pedicel from which flower parts grow Nectaries = Produce nectar at the base of petals Ovary = Where female gametes are formed through meiosis
Match the following processes in plant reproduction with their descriptions:
Pollination = Can be self-pollination or cross-pollination by insects, wind, or other methods Fertilization = Involves the fusion of male and female gametes to form a diploid zygote Seed dispersal = Occurs through animal, wind, water, and self-dispersal methods to ensure survival and minimize competition Dormancy = Period of reduced growth or metabolism, even when conditions are suitable for germination
Match the following seed components with their roles in seed formation:
Zygote = Forms the seed embryo after fertilization Seed coat (testa) = Provides protection to the seed Radicle = Develops into the root of the new plant Plumule = Forms the shoot of the new plant
Match the following plant reproductive structures with their functions:
Anther = Produces male gametes and forms the pollen grain Ovule = Contains the female gametes and is located in the ovary Fruit = Essential for protecting and dispersing seeds, with seedless fruit varieties developed for consumer markets Pollen grain = Carries male gametes for fertilization
Match the following methods of seed formation and dispersal with their functions:
Female gamete formation in the ovule = Occurs through meiosis in the ovary Seed formation after fertilization = Involves the development of the ovule into the seed, with the zygote forming the seed embryo Seedless fruit varieties = Developed for consumer markets to protect and disperse seeds Seed dispersal through animal, wind, water, and self-dispersal methods = Ensures survival and minimizes competition
Study Notes
Plant Reproduction and Seed Formation
- The egg sac in a flower contains the egg cell and two polar nuclei which form the endosperm.
- The receptacle is the thickened part of the pedicel from which flower parts grow.
- Nectaries, located at the base of petals, produce nectar.
- Female gametes are formed in the ovule contained in the ovary through meiosis.
- Male gametes are produced inside the anther and form the pollen grain.
- Pollination can be self-pollination or cross-pollination by insects, wind, or other methods.
- Fertilization involves the fusion of male and female gametes to form a diploid zygote.
- After fertilization, the ovule develops into the seed, with the zygote forming the seed embryo.
- The seed structure includes the embryo, tough seed coat (testa), radicle, plumule, and cotyledons.
- Fruit formation is essential for protecting and dispersing seeds, with seedless fruit varieties developed for consumer markets.
- Seed dispersal occurs through animal, wind, water, and self-dispersal methods to ensure survival and minimize competition.
- Dormancy is a period of reduced growth or metabolism, even when conditions are suitable for germination.
