Answer:

Two Organisms that contain chloroplasts and eyespots are: some green algae and euglenids

Explanation:

   The ocular spot (or stigma) is a photoreceptor organelle found in flagellated (mobile) cells. The eye spot allows cells to detect the direction and intensity of the light and respond by moving towards it (phototaxis) or moving away ("photoshock" or photophobic response). This allows the cell to look for the optimal amount of light for photosynthesis. They are the simplest and most common eyes found in Nature, as they are simply composed of photoreceptor proteins and a signal transduction system that generates a photovoltaic response.

  Talking about the chloroplasts, it is important in the realization of photosynthesis. Main characteristics of chloroplasts: - They are green in color due to the presence of chlorophyll. Inside is the presence of a fluid called stroma. They have DNA, RNA and ribosomes. Thus, they have the ability to perform the process of protein synthesis and multiply and is within the stroma that we have DNA, RNA and ribossomes.

It seems that you have missed the necessary options for us to answer this question, so I had to look for it. Anyway, here is the answer. The two organisms that contain chloroplasts and eyespots are volvox and euglena. Hope this answers your question.

Match each phrase with the correct answer. Group of answer choices Organism in a lichen that provides protection [ Choose ] Orga
jekas [21]

Answer:

Organism in a lichen that provides protection - algae

Organism in a lichen that provides nutrients through photosynthesis - algae

Branched growth form of lichen - fruticose

Leafy growth form of lichen - foliose

Small and flat growth form of lichen - crustose

Explanation:

<em>Lichens are composite organisms that are formed from symbiotic relationships between fungi and cyanobacteria/algae. The Green algae layer offers food to the fungi by photosynthesis while the latter supplies nutrients and offers protection to the algal component. </em>

There are different types of lichen based on the growth structure:

Fruticose lichens grow upright and shrubby and posses either round or flat branches.

Foliose lichen appears like a leaf with upper and lower layers. They are usually flat or convoluted in nature.

Crustose lichens are small in appearance with flat, crusty growth on surfaces on which they grow.
