#sporophyte

[revretch]

Everyone compares pollen to semen, but it's not the same thing at all.

See, with flowering plants, what you're seeing is the sporophyte. It doesn't actually have sex itself. Instead, plants that have "female" parts have separate little plants growing inside their flowers. These are the female gametophytes, which do have sex.

However, plants with "male" parts don't have male gametophytes in them. Instead, they have pollen, which will become male gametophytes when it gets to a female gametophyte.

In other words, pollen isn't like sperm--it's like an egg with little men in it.

None of you thought it might be important to tell me that ferns have sperm that swim???

So.

None of you thought it might be important to tell me that ferns have sperm that swim??? I just had to find all this out on my own?

And, (apparently, & no one thought to bring this up either🙄) fern plants are only one form… they have this 'other form' (tiny, ephemeral, difficult to find in the wild) alternates generations-- Fern spores don't grow into ferns! (WHAT) they grow into 'gemetophytes' (WHAT) THEN you get a fern.

Feel like I've uncovered a massive scandal.

Is it just me or do we only ever learn about liverworts when talking about alternation of generation life cycles or the oldest plant lineages? Recently I was looking through my microscope pictures from last summer, and I must have been too excited to collect samples and look at them to bother posting much of it on here because there are a lot of cool pictures that I never shared. Here are some cute liverwort sporophytes that I unwittingly brought home with a wolf's milk slime mold sample. It was my first time ever seeing liverwort sporophytes, which bear the spore capsule (sporangium) at the tip.

Here's the opened spore capsule with my fingers in the background to provide scale. Unlike moss sporophytes, liverwort sporophytes are relatively ephemeral, often collapsing a day after the capsule opens rather than sticking around for weeks or months or years like mosses.

I'm going to be posting more of my backlog of pictures in the coming days, so buckle up!

Some plant bits for display: botanical model of a moss sporophyte, fern fossil, large pinecone, botanical model of a fruit cross section.

It was interesting trying to make educational models of plant parts that would be magnified because they're for teaching, yet still read as in-scale. Think my fruit should probably have been bigger, and I wasn't able to make the moss spores small enough.

[whats-in-a-sentence]

The development of the seed plant sporophyte can be broken down into three major stages (Figure 17.2): embryogenesis, vegetative development, and reproductive development. (...) An essential feature of this basic architecture is the presence of apical meristems at the tips of the root and shoot axes (see Figure 17.2), which are key to sustaining indeterminate patterns of vegetative growth.

What's funny about flowering plants is that the big plant you're looking at (sporophyte) is never male, female, or even both. Instead, in its flowers it makes separate, smaller plants (gametophytes) that are themselves male or female--the females are called "ovules," and the males are pollen! These little plants are what actually make sperm and eggs and have sex.

So in other words, plants aren't sexed according to their own sex. They're sexed according to whether they "give birth" to male children, female children, or both.
