AsterQuiz Science ExamOnline version Get ready for you exam by Leila Valderrama Valderrama 1 Which part of the flower is responsible for producing pollen grains? a Stigma b Style c Anther 2 The male reproductive part of a flower (stamen) consists of: a Stigma and ovary b Anther and filament c Petal and sepal 3 Which structure protects the flower before it opens? a Sepal b Petal c Carpel 4 The female part of the flower (carpel) includes which three structures? a Anther, filament, and pollen b Stigma, style, and ovary c Roots, stem, and leaves 5 What is the correct order of events in plant reproduction? a Fertilisation → Pollination → Seed formation b Seed formation → Fertilisation → Pollination c Pollination → Fertilisation → Seed formation 6 What happens during fertilisation? a Pollen lands on the stigma b Male and female cells join together inside the ovule c The petals attract animals 7 Why do flowers have colorful petals? a To protect the roots from the sun b To attract insects and other pollinators c To produce food for the plant 8 Which part of the flower receives the pollen during pollination? a Anther b Sepal c Stigma 9 If a seed has wings or light hairs, how is it most likely dispersed? a By animals b By water c By wind 10 Where does a young plant get its food before it can perform photosynthesis? a From the soil b From the sun c From the cotyledon 11 A plant stem helps the plant by a Absorbing water directly from the air b Carrying water and nutrients between the roots and leaves c Protecting the flower before it blooms 12 What do leaves need to capture from the environment to make food? a Light energy and carbon dioxide b Soil and shade c Pollen and minerals 13 What type of reproduction uses a tuber or a runner? a Sexual reproduction (with seeds) b Asexual reproduction c Germination 14 After fertilisation occurs, what does the ovary turn into? a A seed b A new flower c A fruit 15 A seed with sticky hooks is designed to be moved by: a Floating down a river b Sticking to animal fur or human clothes c Flying in the breeze 16 What is a perfect flower? a A flower that has both male (stamen) and female (carpel) parts b A flower with bright colorful petals c A flower that does not need water to grow 17 Which three conditions are necessary for a seed to germinate? a Soil, darkness, and fertilizer b Water, air, and warmth c Light, carbon dioxide, and fruit 18 Why is seed dispersal helpful to new plants? a It makes seeds grow faster b It prevents new plants from competing with parent plants for space and light c It protects seeds from insects 19 How many cotyledons does a dicotyledonous seed have? a One b Two c None 20 Pollination and fertilisation are the exact same process. a True b Falsa 21 During dormancy, a seed is actively growing into a seedling. a True b False 22 The sepal protects the flower bud before it opens. a True b False 23 In cross-pollination, pollen moves between flowers on DIFFERENT plants of the same type. a True b False 24 In fertilisation, a pollen grain produces a __________ that grows through the style. a Seed coat b Pollen tube c Runner 25 What happens during self-pollination? a Pollen travels to a flower on a different plant. b Pollen moves to the stigma of the same flower or plant. c Seeds are dispersed by explosive pods.
