Question Answer
What is asexual reproduction? Asexual reproduction is the production of offspring by an individual without the use of gametes or a partner
What is sexual reproduction? sexual reproduction involves a male and a female, producing sex cells called gametes. the two gametes unite and give rise to a new organism.
what is a gamete? a gamete is a cell which cannot develop any further until it unites with another gamete from the opposite sex
what are the male organs in a plant called? the male organs in a plant are called stamens
what are the female organs in plant called? the female organs in a plant are called carpels
where are the male gametes (stamen) of a plant produced? the male gametes ( stamen) are produced inside the anther
where are the female gametes of a plant produced? the female gametes of a plant are produced in the ovary
what is the function of the filament? the filament holds the anther in the best position to enable it to release its pollen grains
what is the function of the sepal? the sepal protect the flower when it is in a bud stage against insects fungi and frost
what is the function of the petal? the petal is often brightly coloured and scented to attract insects and may produce nectar
what are the three parts of the carpel? the three parts of the carpel are the ovary, style and stigma
what are the two parts of the stamen? the two parts of the stamen are the filament and the anther
what are four examples of monocotyledous flowering plants? four examples of monocot flowers are grasses, wheat, maize and rice
what are four examples of dicotyledonous plants? four examples of dicotyledonous plants are sweet pea, wallflower, primrose and dandelion
what are the two types of flowering plants? monocotyledonous an dicotyledonous plants
what is a monocotyledonous plant a monocot plant is a plant that only contains one cotyledon
what is a dicot plant? a dicot plant is a plant which contains two cotyledons
what is a cotyledon? a cotyledon is a seed leaf that stores food
what is a leguminous plant? a leguminous plant contains its seeds in pods
what are three examples of leguminous plants? peans beans and lupins are all leguminous plants
what are the general features of a monocot flower? monocot flowers are tiny and dull in colour, have no petals or sepals, their reproductive organs are in bracts, have feathery stigmas and three stamens, and two styles
what are the features of dicot flowers? dicot flowers have 5 sepals joined together, 5 petals, a standard, wings, a keel, a single carpel, and ten stamens and 9 filaments
what is pollination? pollination is the transfer of pollen from the anther to a ripe stigma
what is self pollination? self pollination is when pollen is carried from the anther to the stigma of a flower of the same plant
what is cross pollination? cross pollination is when pollen is carried from the anthers of one flower to the stigma of a flower on another plant of the same species
how do plants prevent self pollination? plants prevent self pollination by situating the stigma higher than the anthers, some plants are also self sterile, and the ovules mature before the anthers ripen and split open
how are plants adapted to insect pollination? insect pollinated flowers usually have large brightly coloured petals which are scented and often have nectaries, dark lines called honey guides on petals, anthers tend to be small and located inside the flower where insects tend to brush up against them, some plants produce pollen grains that are sticky and smooth or covered with spiky hairs in order to increase the chances of the pollen attaching to the insects
