Questions and Answers

Match the following flower parts with their descriptions:

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, produce scent to attract insects Stamens = Male part of the plant and consists of anther and filament Carpel = Female part of the plant and consists of stigma, style, and ovary

Match the following flower parts with their functions:

Anther = Produces pollen which forms male gametes 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

Match the following flower parts with their associated plant genders:

Stamens = Male part of the plant Carpel = Female part of the plant Sepals = No specific gender Petals = No specific gender

Match the following plant propagation methods with their descriptions:

Artificial Propagation Cuttings = Part of the shoot is removed and placed in soil or water to form roots Layering = A cut shoot is pegged into soil and develops into a new plant Grafting = A shoot twig (scion) is removed and taped into the root stock Micropropagation = Individual cells i.e., stem, root, or leaf, can be removed from a plant and then grown in tissue culture Signup and view all the answers

Match the following plant propagation methods with their examples:

Artificial Propagation Cuttings = Geranium Layering = Blackberry Grafting = Apples Micropropagation = Bananas Signup and view all the answers

Match the following parts of the plant with their role in propagation:

Plantlet = When it touches the ground, roots grow into the ground Runner = Withers when the new plant becomes independent Scion = Part of the plant that is removed and taped into the root stock in grafting Adventitious roots = Grow after one year in layering and then are cut off from parent plant Signup and view all the answers

Match the following seed dispersal methods with their examples:

Animal Dispersal = Tomato seeds and apple seeds Wind Dispersal = Sycamore parachutes and dandelion parachutes Self-dispersal = Gorse Water-dispersal = Yellow water lily Signup and view all the answers

Match the following types of asexual reproduction with their examples:

Stem Tubers = Potatoes Root Tubers = Sweet potatoes Bulbs = Daffodils Plantlets = Strawberry plants Signup and view all the answers

Match the following stages in germination with their descriptions:

Radicle Emergence = The root starts to grow downwards from the seed Plumule Growth = The shoot starts to grow upwards from the seed Leaf Break = The leaves break the surface and the seedling begins to photosynthesize Weight Gain = The plant starts to gain weight Signup and view all the answers

Match the following methods of breaking dormancy with their descriptions:

Soaking the seeds in chemicals = To wash out inhibitors Applying plant hormones such as gibberellins = To promote germination Soaking the Testa = To allow water to enter the seed Cracking the Testa = To break the seed coat Signup and view all the answers

Match the following parts of a flower with their descriptions:

Egg sac = Contains the egg cell and two polar nuclei which will form the endosperm Receptacle = Thickened part of the pedicel from which the flower parts grow Nectary = Located at the base of the petals and produces nectar Pollen grain = Matures, forming a tough layer on the outside called the exine Signup and view all the answers

Match the following terms related to pollination with their definitions:

Self-pollination = Occurs when the anther and stigma are on the same plant, leading to less variation Cross-pollination = Occurs when the anthers and stigma are on different plants, promoting genetic diversity Insect Pollination = Bees visit the flower to collect nectar and pollen to feed their young, becoming covered in pollen Wind Pollination = Plants like wheat and barley produce light pollen which drifts away on the breeze Signup and view all the answers

Match the following terms related to fertilization with their descriptions:

Fertilization = The fusion of the male gamete with the female gamete to form a diploid zygote Pollen tube = Grows down the style to the ovule, guided by chemotropism and the tube nucleus Generative nucleus = Divides by mitosis to form two sperm nuclei as the pollen tube grows down Double fertilization = One male gamete fuses with the egg cell, while the other fuses with the two polar nuclei to form the endosperm Signup and view all the answers

Match the following seed structures with their descriptions:

Embryo = Part of the seed that will develop into the new plant Testa = A tough and hard seed coat which protects the seed before germination Radicle = First part of the new plant to emerge from the seed, develops into the root Cotyledons = Seed leaves which contain food reserves used in the early stage of germination Signup and view all the answers
