Plant "reproduction"?

I am doing a project which is about comparing reproduction in a range of organisms.





We had to choose a mammal, something by binary fission so i chose amoeba, and the final choice is a flower/plant.





I want to do arum lilies or lotus flowers but I cant find anything about them producing more of themselves by natural means, all the info is by human help.





we're supposssed to outline whether they reproduce sexually or asexually, discuss any courtship and parental care and discuss whether they reproduce by K or R strategies.





I'm kinda confused cos i thought pollen just got blown by the wind from one flower to another and new flowers grow??





please help

Plant "reproduction"?
Mammals are easy, but you have to choose any type of bacteria for binary fission, it should be really easy.


All plants, with or without flowers, reproduce sexually. In the case of flowering plants, the pollen from one flower has to reach the stigma of another flower (if it happens in the same flower the plant will be a clone, but it ver rarely happens in nature). There are two ways in which it can happen, either the wind carries the pollen (as it happens in cereals and grass) or an animal pollinates the flower, usually insects like bees or butterflies, but also some birds can do it. The flowers have special structures, colours, etc. that help them draw their pollinator. Once the pollen reaches the stigma two things happen. Pollen is actually formed of two cells, and double fecundation occurs, one of the cells fertilizes the egg cell, which will eventually turn into the embryo that will be inside the seed; the other cells fetilizes one accessory cell that will become the endosperm, a tissue that will provide energy to the embryo or "feed" it. The endosperm is the fleshy part of the fruits, it usually looks that way. Plants don't obviously have parental care, but sometimes the seed germinates while the fruit is still attached to the plant. The reproductive strategies of plants vary depending on which plant family or group you are talking about.


Flowering plants are divided into 2 mayor classes: Liliopsida %26amp; Magnoliopsida. Lilies are in class Liliopsida inside the subclass Lilidae, the order Liliales %26amp; the family Liliaceae. They are the most evolved monocots and are pollinated mostly by insects.


Lotus flowers, on the other hand, are in class Magnoliopsida, subclass Magnoliidae, order Nymphaeales (all lotus flowers) and there are 2 families Nelumbonaceae and Nymphaeaceae. These are the most primitive dicots and have relictual characters that belonged to the primitive angiosperms. Their pollen is uniaperturate, it only has one germination pore. Since these plants live in water, they are pollinated through water, the pollen is transported trough water to the stigma.





Hope it helps :)
Reply:Pollen is passed on by bees and other insects. they go in to the flowers to collect pollen or nectar and so pass it from flower to flower.
Reply:All plants reproduce sexually, by exchanging pollen from one flower to another. Pollen contains gametes (like sperm), that combine with the gametes present in plants' female sexual organs to form a fertilized cell. The flower then develops into a fruit containing seeds. Note that flowers can be either only male (containing stamens), only female (containing pistils), or can be hermaphroditic (containing both), depending on the plant. Also, some plants are capable of self-fertilizing, while others are not.





Incidentally, amoeba do NOT reproduce by binary fission - they are eukaryotes and undergo mitosis.
Reply:asexually through pollen
Reply:use the 'bumblebee orchid' as an example. it has flowers that look and smell like a female bumble bee. the male bee is tricked by this flower and attempts to mate with it. instead of fertilizing a bee, the plant attaches a sac of pollen onto the bee. the next time the male bee makes the same mistake, the pollen sac is transfered to the stigma of the next flower and fertilization takes place.





here are a few links that describe this cool system:

Reply:Plants produce using pollen and stigmas or something. Or probably ovaries. So, what happesn is that the pollen is carried by the wind, or a bee, to the ovaries of the flower where it polinates the seed and fertilizers the plant.
Reply:http://en.wikipedia.org/wiki/Zantedeschi... contains some good information on the plant you are looking at. Under normal conditions it will reproduce using its rhizomes - underground root systems, (asexual) however when this water loving plant suffers drought conditions it will flower and thus engage in sexual reproduction. This will not just be by pollen being blown, but by insects and animals engaging in pollenation.
