The diploid form in a plant's life cycle is called what?

The diploid form in a plant's life cycle is called the sporophyte. To understand this, let's break it down:

1. Life cycle: The life cycle of a plant involves various stages and processes through which it undergoes growth, reproduction, and development.

2. Diploid: In genetics, diploid refers to the condition where an organism has two sets of chromosomes, one from each parent. Diploidy is represented by the symbol "2n".

3. Sporophyte: The sporophyte is the stage in the plant's life cycle where it produces spores. These spores are formed through a process called meiosis, which halves the number of chromosomes and produces haploid cells. The sporophyte is typically the dominant and long-lived stage in the life cycle of most plants.

In summary, the diploid form in a plant's life cycle is called the sporophyte because it is the stage where the plant produces spores through meiosis.
