Answer:The Cycad tree is the sporophyte.They have flagellated sperm.
Explanation:
During pollination, the contents of the megaspore divide to form many–celled gamateophyte called the endosperm and archegonium. There is a micropyle opening with a sticky fluid, which traps the wind-borne male gametophyte (microspores) which,at this time is made up of prothallus cell;an antheridial cell and a large tube cell. The trapped microspore is sucked into the archegonia chamber. Antherizoids are released, but only one penetrates each oospore and fuses with the female nucleus. The zygote is formed in the ovule and the later develops into seed.The diploid seed germinates into a new sporophyte plant and the life cycle begins again. Examples of cycad include Cycas circinalis ,Cycas celebrical and Cycas revoluta
The answer would be used batteries. You would be able to recycle the vegetable waste within fertilizing and/or throw it away safely by disposing it in a trashcan since it is not a hazard towards the environment. As for aluminum cans, they are recyclable and are easy to use again once it is filtered through the system. However, batteries are NOT recyclable nor easy to dispose because they can release Alkaline which can harm the environment.
