FLOWERS STAMENPISTIL ATTRACT INSECTS AND ANIMAL POLLINATORS PETALS PROTECT THE FLOWER MEANWHILE IS A BUD. MALEFEMALESEPALS IN THE ANTHER IS PRODUCED THE POLLEN STIGMA: SITE OF POLLINATION PRODUCE POLLEN GRAINS INSIDE AN OVARY, EGG CELLS: OVULES OVARY IS THE BASE OF PISTIL

A flower is pollinated when a pollen grain lands on its stigma. Each carpel grows into a fruit which contains the seeds.

POLLINATION Organize the following words : anther - to the – poller grains – from the – stigma – of - transfer

POLLINATION IS THE TRANSFER OF POLLEN GRAINS FROM THE AHTHER TO THE STIGMA.

Some flowers secrete a sugary liquid(nectar), which pollinators use as food.

As an animal explores these flowers, pollen sticks on its body. When animals wanders away, it tranfers the pollen to the stigma of another flower.

Fertilization Pollen grain Stigma The tissue of the pistil Ovule zygote Two sperms Egg cells A pollen tube #1 #2 Two nuclei

Pollen grains germinate on the stigma, growing down the style to reach an ovule. Fertilized ovules develop into seeds. The carpel enlarges to form the flesh of the fruit and to protect the ovary.

POLLINATION IS NOT THE EQUIVALENT OF FERTILIZATION. FERTILIZATION INVOLVES THE UNION OF EGG AND SPERM AND MAY NOT OCCUR UNTIL WEEKS OR MONTHS AFTER POLLINATION HAS TAKEN PLACE.

FERTILIZATION CAUSES RAPID CHANGES TO OCCUR IN FLOWER. 1.The ovule develops into a seed, often with a tough coat protecting the developing plant and its supply. 2.The ovary grows larger and develop into a fruit(enlarged ovary of plant that contains seeds)

Flowering plants use the wind, insects, bats, birds and mammals to transfer pollen from the male (stamen) part of the flower to the female (stigma) part of the flower.

Seeds dispersal: Seeds are dispersed in many different ways: Wind Explosion Water Animals Birds Scatter

Some seeds are hidden in the ground as a winter store. Some fruits have hooks on them and cling to fur or clothes.

Birds and animals eat the fruits and excrete the seeds away from the parent plant.

GERMINATION IS: The growth of the root through the seed coat,
