<span>Answer : spores, which grow into
a gametophyte<span>
</span><span>A
sporophyte produces spores therefore those plants that have spores is called
sporophyte. A sporophyte is a type of a diploid organism so, which means
that meiosis must occur in order to be able to produce haploid cells containing
half number of chromosomes. Meiosis in sporophyte occurs in an area called
sporangia. The spores that are being created inside sporangia shall be release
into the air. Mitosis is expected to take place on a single haploid spore in
order to be a multicellular gametophyte.</span></span>
Answer:
A. Phytoplankton
Explanation:
They as producers contribute the most. Others do too, but not as much.
Answer:
The endosymbiotic event that brought chloroplast in eukaryotic cells happened after the lineage delivered.
Explanation:
The endosymbiotic theory says that the ancestral cell gains the ability of photosynthesis when it engulfed a photosynthetic bacteria and this bacteria remained in a symbiotic relationship with the ancestral cell and evolved as chloroplast in plants that can perform photosynthesis.
All the eukaryotes do not have this internal structure like chloroplast because this endosymbiotic event must be happened after the divergence of the lineage into different groups. Therefore plant cells have chloroplast and animals cell do not have.
I would say it deactivates, because enzymes are picky about the type of environment they are in and will only work if they have the right environment. Hope i help.
