Asexual reproduction in plants - NATURALLY: The Parent plant sends out _______, which are ____-growing stems that grow out sideways, just above the ______ The _______ take root at various points ( a short distance away & ___ plants start to grow The new plants are CLONES of the parent plant,so there's __ genetic variation between them. This process is a result of _______

Fertilisation: After pollination, the pollen grain grows a ____ from the ______, down the _____ (digesting though tissue), and into the _____. The pollen _______ from the male gamete then moves down the tube. Here it grows around to the opening in an _____. The tip of the tube dissolves, allowing the nucleus from the pollen to join with a female gamete in the ovule to make a ______. This divides by ________ to form an _______ Each Fertilised female gamete (ovule) forms a ____, and the ovary develops into a _____ around it

Pollination: Pollen grains are the ____ gametes and the ovules are the ______ gametes. Pollen grains are produced in the _______ of the stamens. The gametes are formed by _______ During pollination, pollen grains are transferred from the _______ to the ______. If this occurs within the same flower it is called ____-pollination, and if the pollen grains are transferred to another flower it is called _____-pollination, which relies on the pollen being transferred by _______ or wind

Seed & Fruit formation: Each Fertilised female gamete (ovule) forms a ____, and the ovary develops into a _____ around it. Each seed contains an embryo plant, which has: - A root ( the _______) and a shoot (the ______) - The __________ acts as the food store while the seed __________ - Seed coat, also known as the _____ The ovary wall becomes the _____ and the rest of the plant dies away around it Seeds are adapted to disperse as far away from the ______ plant as possible, to avoid competition for water minerals and light. They may be dispersed by animals, wind or water

Seed Germination: 1) During germination, the seeds own ____ store is used up. It gets _______ for respiration from this supply. 2) this allows the radicle and pumule to grow. The Radicle grows into the ____ and absorbs water and mineral ions. The pumule grows towards the _____ 3) Once the plant has grown enough to produce _____ leaves, it can get its own energy from ______________, meaning germination is over.
