Sexual reproduction in flowering plants
What you must be able to do:
You need to be able to name all the parts of a flower (find different
pictures of flowers on the internet to practice).
You need to be able to label all the parts of a seed / bean
What develops from the ovule, ovary and egg cell (in a flower)?
Name and explain the methods of a plant of dispersing seeds. Be able to
recognise this in pictures of fruits.
Name and explain the methods by which a plant can be pollinated. Name
the characteristics of flowers that use each method.
Explain how a plant fills the fruits and the seeds leaves with nutrients
(story from leaves to fruit (seed leaves) step by step.
What structures are involved in this process?
What is the advantage of storing nutrients in seeds and of storing
nutrients in fruits?
Explain the sequence of events starting from pollination, growth of a
pollen tube, fertilisation, development of a seed, germination and growth
of a new plant: the life cycle of a plant. Name all the names of the parts
of the plant and the names of the processes that take place.
