Question

The male trees of a plant with vascular tissue and cones have multiflagellated sperm. The female trees produce rotten-smelling fleshy seeds that contain butyric acid. Which of the following is the most logical conclusion about the classification of this plant?

Answer 12

First of all lemme tell you that `Ginkoales` is one of the 4 orders that come under the larger group \(\bf Coniferophyta\)

Answer 13

Now both Cycadophyta and Ginkoales have cones in male species. But the keyword here is seeds contains `butyric acid`

Answer 14

You wanna chose any one?

HINT: The answer is a living fossil

Answer 18

I'm going with Ginkgophyta..

Answer 19

"Its fleshy outer layer (the sarcotesta) is light yellow-brown, soft, and fruit-like. It is attractive in appearance, but contains butyric acid."

Answer 20

Yes, that's \(\huge \checkmark\)

Ginkgoales are the oldest of coniferophyta. Maximum plants in this group are extinct.

One of the example is \(\ Ginko~biloba\), it is a living fossil and is also called as `Maiden hair tree` These have cones on male plant and as question says contain butyric acid in seeds.
