Answer:

A phylogenetic tree is a diagram that represents evolutionary relationships among organisms. Phylogenetic trees are hypotheses, not definitive facts. The pattern of branching in a phylogenetic tree reflects how species or other groups evolved from a series of common ancestors.

What is true of matter in ecosystems?
Sidana [21]
D.Elements continuously cycle between the physical environment and living organisms.

Ecosystem is encompassing all the life on earth in the physical environment that supports it. An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.  <span> </span>

The sporophyte of an unknown plant species grows as a separate plant than the gametophyte. The plant produces both female and fl
N76 [4]

Answer:

The correct answer would be "The plant is a fern, and sporophyte is its dominant phase".

Ferns refer to the lower plants which do not bear flowers, have leafy or feathery fronds, and they reproduce by spores.

They show alternation of generation in which sporophyte is the dominant stage.

The mature diploid sporophyte releases haploid spores with the help of meiotic divisions.

The haploid spore divides by mitotic division and matures into a haploid gametophyte. The single gametophyte bears antheridium and archegonium which release flagellated male gametes and egg (female gamete) respectively with the help of mitotic division.

The gametes fertilize to produce a diploid zygote.

The zygote divides mitotically and matures into the diploid sporophyte.
