Question | Answer |
the female part of the flower that looks like a large vase | Pistil |
the male part of the flower that has a filament and an ANTHER | Stamen |
what is produced in the ANTHER | Pollen |
what is located inside the pollen | sperm |
Describe the chromosome arrangement in the sperm or egg of a flower | they have half the number of chromosomes found in typical cells of the plant ...they are haploid |
What is the large part of the pistil located at the bottom of the structure | ovary |
What is located within the ovary of the flower | ovulues or eggs... after fertilization the eggs will become seeds and the ovary will become the fruit ( picture an apple) |
where does pollination occur in a flower | On top of the pistil... there is a sticky surface |
where does fertilization occur in the flower | At the bottom of the ovary where the eggs are located |
How does the sperm of a flowering plant get to the egg of a flowering plant | the pollen (containing sperm) lands on the pistil and starts to grow a POLLEN TUBE. The sperm travels down the pollen tube and will then unite with the egg within the ovary |
What is self pollination | when a plant has both male and female reproductive structures and the pollen goes from the male structure to the female structure within the same plant |
what is another way that some people describe self pollination..they could also say _____ | Self fertilization ( self pollination is probably a better term) |
what is cross pollination | When the pollen goes from the male structure to the female structure in ANOTHER plant... it must be the same species ( pea to pea , rose to rose etc... not pea to rose) |
What is pollination | when the pollen containing the sperm goes from the male's stamen to the female's pistil by insect, bird, bat, wind, or other means... two types are self and cross pollination |
What is fertilization | when the sperm unites with an egg to make a new organism ( first cell is a zygote).. part of sexual reproduction |
