Answer:Phaeophyta--Described as "hairy" in appearance produce alginic acid, which can be used as a thickening agent.
Rhodophyta ;are utilized commercially to produce carrageenan and can photosynthesize at depths greater than 10 meters
Chlorophyta;Considered the progenitor of land plants, have 18S rRNA sequences comparable to plants
Chrysophyta;The is a diverse group that includes the diatoms, a major component of phytoplankton
Explanation:algae are a diverse group of organisms with majority of them living in water and a few on land. They are green and contains chlorophyll.they also contains phycobillins pigments.
Chlorophyta are green algae that exist in water habitat an example is Chlamydomanas reinhardi.they have similar structures with higher plants such as chlorophyll, cellulose cell wall and stores food as starch.
The chrysophyta includes diatoms.diatoms have a cell wall composed of pectin and deposits of silica. They may occur in large deposit as diatomaceous earth.
Phaeophyta--are brown algae. An example is sea weed they are found in deeper ocean waters. Sea weed has a thallus which branches into a basal holdfast that aids attachment to rocks.their blade allows the plant to float
Rhodophyta are algae which are sometimes Unicellular in form they have a characteristic red color due to the presence of phycoerythrin along with phycocyanin, chlorophyll.they are used as source of algar for microorganism culture.

b. active phase
c. transition phase
2. Second Stage: Pushing and Birth
3. Third Stage: Delivery of the Placenta
Answer:
Pumps, also called transporters, are transmembrane proteins that actively move ions and/or solutes against a concentration or electrochemical gradient across biological membranes. One moves with the concentration gradient (high to low) which powers the movement of the other against the gradient (low to high).
The study of plants is called botany. There are different types of plants in the living being and these are algae, bryophytes, pteridophytes, gymnosperm, and angiosperm.
The correct answer is mentioned as follows:-
<h3>GYMNOSPERM</h3>
- The less developed plant which does not bear flowers and has covered less seed is called gymnosperm.
According to the question, the diagram is not mentioned in the question hence we can not able to tell the characteristics of the area marked as X. The plants do not look like palm trees.
Hence, provide it with the diagram for better assessment.
