Fern spore germinates into prothallus.
Explanation:
Ferns are members of phylum pteridophyta, the vascular cryptogams.
These are first land plants which are known to have a distinct conducting system of xylem and phloem.
They reproduce by forming spores that germinates into a heart shaped gametophyte.
The gametophyte of the fern is called prothallus.
The heart shaped gametophyte has root like structure called rhizoids.
These rhizoids anchor the gametophyte to the substratum.

<h3>What are the various parts of the brain?</h3>
The brain is the most important organ found in the body. The brain controls all the other processes occurring in the body.
The brain consists of cells called neurons which are interconnected to each other and which receive information from other parts of the body, processes it and sends out response signals.
The various parts of the brain are as follows:
- subdural space
- third ventricle
- fourth ventricle
- lateral ventricle
- foramen of magendie
- pia matter
- corpus callosum
- straight sinus
- arachnoid villa
- foramen of monroe
- dura matter
- skull - the protective covering of the brain
- subarachnoid space
- cerebral aqueduct
- choroid plexus
- arachnoid
- cerebellum
- cerebrum
In conclusion, the various parts of the brain function to make the brain work efficiently.

Perceptual constancy
Perceptual constancy is the
ability to view or consider an object as unchanged under different conditions
such as changes in distance, physical features or illumination. For the
question above, Immanuel knows the kite is not shrinking due to his brain's
ability to maintain perceptual constancy.
I would say burning a campfire would contribute most to climate change over the others.
C)
Bacteria and other small organisms within an ecosystem play an important role in maintaining homeostasis of an ecosystem while also helping to break down dead materials. These small organism play a vital role in decomposing of dead plant and animal matter that then becomes nutrients for the ecosystem in the future provide fertile soil for new plant life to grow supporting the cycle of life in an ecosystem.
