Algae are photosynthetic, but they are also unicellular organisms (Euglena) and shares some of the common features with plants as well as animals. They move like animals and perform photosynthesis like plants. Therefore, they are classified into Protists, and not the Algae. Their most features resemble the non-photosynthetic protozoa, and not plants, and therefore, are put into the Protista.
They also lack a cell wall, which is a feature of plants.
Some scientists advocate their classification in plants because of their sexual mode of reproductiona, and formation of spores.
Answer:
cell transport or membrane transport helps in the transport of solute molecules and ion across the plasma membrane and helps in maintaining homeostasis of these molecules in the biological system.
Explanation:
Homeostasis is very very important to maintain a steady body physiology and the maintenance of steady body physiology is highly significant because any type of disturbance in the homeostasis can leads various physiological abnormalities.
Various membrane transport process such as osmosis helps in the movement of water from high concentration region to the region of low water concentration until equilibrium is reached.Thus osmosis helps to maintain water homeostasis in our body.
By the same way glucose transporter maintain the homeostasis of glucose inside our body.
Organisms with the most favourable traits will increase their success rate in a particular environment. Organisms with favorable traits are more likely to reproduce and pass on their traits than organisms without favorable traits, allowing it to survive.
Answer;
Semi-permeability means that only certain molecules are allowed to pass through.
Explanation;
-Semi-permeability is one of the features of a cell membrane, which means that the membrane allows selective movement of materials in and out of the cell; that is only certain molecules can enter or leave the cell.
-For example smaller molecules such water and ions such as potassium and sodium ions are able to leave and enter the cell, while other molecules that are large such as protein molecules can not enter or leave the cell.
Answer:
I'm not sure but maybe for the first it's less than 3% and for the second it's equal to 3%?
