4. none of them
Algae live in bodies of water and damp places and are commonly found in both aquatic and terrestrial environments. Terrestrial algae mostly live in moist, tropical areas. They prefer wet places because they do not have vascular tissues and the other necessary adaptations to survive on land.
Enzymes can either help break a substrate molecule down to smaller ones or help substrate molecules join to form a larger one. They work as catalysts by reducing the activation energy of the reaction by providing an alternate pathway for it. The enzymes are specific with their substrates.
Answer:
The correct answer is A it transport the food generated by photosynthesis.
Explanation:
Both xylem and phloem are the examples of vascular tissue present in plants.xylem helps in the transport of water from root to different parts of the plants.
Whereas phloem helps in the transport of photo synthate from mesophyll tissue to sieve element companion cell complex.The transport of photosynthate to different non photo sythetic parts of a plant involves both symplastic and appoplastic pathway.
Symplastic pathway is a passive process depending on the pressure gradient for the transport of solutes through the plasmodesmata which connect 2 adjacent plant cells.
Appoplastic pathway is an active transport process occuring against the concentration gradient which does not involve plasmodesmata.
The correct answer is:
D. It divides one diploid cell into four haploid cells.
Explanation:
Meiosis is a specific type of cell division that reduces the chromosome number by half, forming four haploid cells, each genetically different from the parent cell that yielded growth to them. Meiosis is a method where a single cell divides double to produce four cells comprising half the innovative amount of genetic information.
