The two main processes by which plant cells absorb, release, and use
energy are photosynthesis and respiration. The
process of photosynthesis is present in the chloroplasts of a pant cell.
Photosynthesis uses the sun’s rays in the form of electromagnetic energy to
convert it into chemical energy to be used for the plants. It needs proteins
that are present in the plants to perform a series of necessary conversions.
Moreover, the energy from the sun is the main catalyst to convert the
carbohydrates in the plant into simpler sugars. And then a series of complex
reaction takes place that their end product is oxygen. The oxygen produced is
the cellular respiration.
Answer:
Dinoflagellates
Explanation:
Protists are unicellular eukaryotes and dinoflagellates is a protist that is responsible for causing annual Florida red tides. When a large amount of dinoflagellates accumulates in the ocean they make the sea color red which is also called an algal bloom.
They also secrete a toxin that kills lots of aquatic animals. They are also toxic to other creatures like birds, humans. They come together to reproduce in a definite area therefore they accumulate together in large amounts causing red tides annually. Therefore the correct answer is dinoflagellates.
The correct answer is xylem.
<span>Xylem is a type of plants’ transport tissue. The function of the xylem is to transport water and solutes from the roots to the leaves. The xylem transport system is composed of continuous tubes called xylem vessels. Xylem vessels enable transport (after absorption from the soil through root hair cells) up the stem to the leaves. Water evaporation from the leaves (transpiration) is also mainteined by xylem. Xylem vessels consist of dead cells with a thick, strengthened cell wall with a cellulose and hollow lumen. Vessel element is one of the cell types found in xylem and together with tracheids, is involved in the actual transport.</span>
